First text published by G. Allport in the 1930s

First theoretical models date back to William James and Sigmund Freud (both late 1800s)

Considerable variability in explanations for personality (biological/genetic models, psychodynamic, self-theory, etc.)

Common Elements:

Stability (situations and time) – differentiated from mood

Research on stability over the lifespan (greater as we age)

Affective, cognitive and behavioral components

Personality assessment

Personality assessment

Recent survey of practicing Ph.D.s, PsyD.s, and Ed.s revealed that only 32% use personality tests and only 43% do treatment planning.

De-emphasis in personality training occurred at the same time as Mischel shock in 1968, so clinicians trained in the late 1960s and 1970s did not value personality assessment

Today, treatment planning based on assessments is essential from both an ethical standpoint and for insurance reimbursement

Objective assessments
Objective assessments?

  • How can personality assessment be more objective

    • assess any biases and correct for them (lie, defensiveness)

    • find a method to avoid such biases

    • look for convergence with reports from others

    • assess with low face valid instruments and look for consistent patterns (though this only really addresses intentional faking)

  • Personality assessment is used to further describe the client, just as a diagnosis does (note that you would not say that depression is causing the patient's behaviors, you merely use the term to summarize a cluster of behaviors. The diagnosis itself also does not necessarily imply a causal mechanism nor an explanation - those from different perspectives would define it differently)

    • e.g., if someone is depressed it could be explained biologically, cognitively, behaviorally, or even in psychodynamic terms

The structure of personality

The structure of personality

Personality involves stable patterns of behavior, affect, and cognitions. So how stable is stable? (states vs. traits)

Levels of analysis

1. factors - groups of traits that show better global predictive utility (e.g., Big 5 of N, E, O, A, C; The Big 3 of N, E, P; Big 2)

2. traits - clusters of consistent individual behaviors

3. habits - consistent (over time) individual behaviors

4. single acts - individual behaviors

All levels are used to predict future behavior with the top being the most robust

Consider this model when recommending or implementing change in clients

Predicting behavior

Predicting behavior

Difficult to predict specific single behaviors from global trends; (Epstein, 1983)

For clinical evaluations, if the context of interest is known, then you may want to trade off the generalizability and give a specific prediction

e.g., Pt.’s test scores indicate that he is generally impulsive. This may be exacerbated when in the company of other individuals who are also impulsive and when the individual is drinking, as alcohol minimizes any inhibition processes that he might have. This substantially increases the likelihood that he will act impulsively when...

Two key discussions
Two key discussions

  • Read material in advance and know your MMPI

  • Scheduled discussion:

  • Should we use projective tests?

  • Are they tests or techniques?

Assessing axis i and ii

Assessing Axis I and II

Personality addresses both AXIS I and AXIS II disorders.

What are some AXIS I disorders that might be related to personality traits?e.g.,

depression and NA/Neuroticism

anxiety and NA/neuroticism

impulse control disorders & extraversion/sensation seeking

AXIS II personality disorders explicitly link up with personality assessments (video & DSM-IV)

Cluster A (odd): Paranoid, Schizoid, Schizotypal

Custer B (emotional): ASPD, Borderline, Histrionic, Narcissistic

Cluster C (anxious): Avoidant, Dependent, Obsessive-Compulsive

PD NOS – features of several Dx,but does not meet criteria for any one.

Selecting a test battery see beutler 1995
Selecting a test battery (see Beutler, 1995)

  • What is the referral question?

    • Single most important determinant

  • Are there any limiting factors with regard to the client?

  • Context of the evaluation? (work, school, hospital, etc.)

  • Follow up assessment relevant to trait findings (e.g., patients who show impulse control problems should also be assessed for potential for acting out violently)

  • Problem focused or broad, multipurpose battery

    • Nomothetic (allows for normative evaluations) or ipsative (allows for the evaluation of the individual) analysis

If using qualitative methods consider
If using qualitative methods, consider:

  • 1.Method appropriateness – are there quantitative methods that you could use instead?

  • 2.Openness – make clear the theoretical orientation that undergirds the qualitative assessment

  • 3.Theoretical sensitivity – use qualitative methods that are based on accepted theories not your own theories 4.Bracketing of expectation – you must explicitly state where your conclusions depart from accepted theories 5.Responsibility – how were the qualitative methods administered and interpreted

  • 6.Saturation/generalizability – when assessing traits, sample from a large number and wide range of situations 7.verification of methods – cross-validate your methods using other reports, other test material to see if it agrees with your conclusions, do findings predict outcomes, etc.

If using qualitative methods consider cont
If using qualitative methods, consider: (cont)

  • 8.grounding – stay close to the data when making interpretations (no big theoretical leaps)

  • 9.coherence – do all of the interpretations fit together to make a coherent story

  • 10.believability/usefulness – does the use of the qualitative method provide more info on the client, or just raise more questions? Does it result in a believable narrative?

  • 11. Intelligibility – Is the report readable and jargon free?

Mmpi hathaway mckinley 1943
MMPI (Hathaway & McKinley, 1943)

  • 10 clinical scales and 3 validity scales

  • Empirical scale development with items selected based on their ability to differentiate normals, from a target group (another clinical group with similar symptoms was sometimes also employed)

  • Clients should be 18 or older & 6th grade education

  • Generally lower face validity (breaks with tradition of items that clearly sample the domain of interest); most relevant for clinical population

Mmpi development
MMPI development

  • Item pool derived from psychological and psychiatric reports, textbooks, previous scales, etc.

  • Criterion group composition

    • Minnesota normals – 724 relatives and visitors of patients at the U. of M. Hospitals, 265 recent high school grads, 265 administration workers, and 254 medical patients

    • Clinical groups – 221 patients representing the major psychiatric categories (excludes those with multiple diagnoses, or questionable diagnoses)

  • Item analysis to identify those items differentiating the clinical and normal groups

Mmpi development cont
MMPI development – cont.

  • The items that could differentiate were then cross validated with new groups of normals and patients

  • Later developed two non-clinical scales

    • M/F – initially to identify male homosexuals was augmented with broader items

    • Si – derived from an introversion/extraversion scale and cross validated by predicting involvement in college activities in a second sample (all female college students)

  • Validity scales were either derived rationally (L & K) or from baserates in the normal group (F)

Utility of the mmpi
Utility of the MMPI

  • Not considered a diagnostic inventory (as was originally intended)

  • Ineffective at differential diagnosis (based on how it was originally developed)

  • Numerical scale labels was intended to further minimize the connection with a specific diagnostic label

Some problems with mmpi
Some problems with MMPI

  • Method of determining the criterion group

  • The PIGs were not a truly random group (relatives and friends of those in the hospital – though largely the medical patients); convenient

  • Criterion and PIGs were largely from the midwest, in the late 1930s/early 1940s

  • Utility of some of the scales as it matched diagnostic concerns of that era, dated and culture-specific item content, and representativeness of the norm group.

Mmpi vs mmpi 2 1989
MMPI vs. MMPI-2 (1989)

  • MMPI was the most widely used personality test in all pops (though only validated for inpatient adult samples)

  • MMPI validation and norm samples were ones of convenience with limited variability on education (M=8 years), coming from a rural background in the midwest

  • Normative data collected in the 1930s

  • Clinical cut-off now defined by t-score of 65 vs. 70 on the MMPI

Mmpi vs mmpi 2

  • Advantages of updating the test

    • more representative norms (based on projected census data)

    • relevance of the items

    • language employed for the items (both temporally laden references like “drop the hanky”, and gender biases in item content)

    • addition of new scales of relevance today

    • Uniform T-score transformation now used so that T-scores reflect percentile ranks that are the same across all clinical scales

Mmpi vs mmpi 21

  • Disadvantages to all updates

    • over 20,000 published studies no longer apply

    • MMPI-2 must revalidate all of the scales

    • inability to make comparisons with adolescent scores (MMPI-2 vs. MMPI-A)

    • Many of the new scales are very short and lack appropriate psychometric properties

    • How often should we redevelop or renorm the scale?

Mmpi 2 1989 567 items
MMPI-2 (1989): 567 items

  • Norm group = 2,600 community based subjects

    • 1138 m & 1462 f, aged 18-85 (M=41, SD15.3), education 3 yrs - 20+, 61% married median incomes $25-$35,000, 3% of m and 6% of f receiving mental health treatment

    • 81% Caucasian, 12% A-A, 3% Hispanic, 3% Native American, 1% Asian-American

Validity scales
Validity scales

  • Assumption that the clinical population will not be able to answer forthright

  • Lie – naive or unsophisticated lying (low SES and education)

  • K – less obvious (high SES and education) defensiveness is a component of all responding

  • F – answering questions in such a way so as to be different from 90% or more of the population (non-normative responses); See fake bad/fake good profiles

  • F – K Index = can be used to indicate fake bad, with larger numbers making it more likely (little evidence to suggest that fake good can be detected); see p. 38

Clinical scales
Clinical Scales

  • 1. Hs - exaggerated concerns re: physical illness, or tendency to report symptoms

  • 2. D - Clinical dep; unhappy & pessimistic about the future

  • 3. Hy - conversion reactions (substitute illness for emotions)

  • 4. Pd - History of delinquency, antisocial behavior (non-conventional re: moral standards)

Clinical scales continued
Clinical scales - continued

  • 5. Mf - prototypical gender identity (military recruits, stewardesses, homosexual males students)

  • 6. Pa - paranoid symptoms (ideas of reference, persecution, grandeur)

  • 7. Pt - anxious, obsessive-compulsive, guilt ridden, self-doubts

  • 8. Sc - thought disorder, perceptual abnormalities (various types of Schiz.)

Clinical scales continued1
Clinical Scales - continued

  • 9. Ma - exhibition of mania, elevated mood, excessive activity, distractibility, (possible manic-depression or BP II)

  • 10. Si - college students scoring in the extreme range on introversion - extra.

  • Costa & McCrae (1990) suggest that the MMPI-2 wont work in the normal pop. As people don’t respond “passively” to items

New validity indexes
New Validity Indexes

  • Basic validity comes from L, F, & K

  • VRIN (variable response inconsistency)

    • 47 pairs of items that should be answered similarly or the opposing direction. Client gets a point for each inconsistent response.

    • A completely random response set results in T scores of 96 for m and 98 for f (>80 inval.)

    • acquiescent responding T = 50

New validity cont
New Validity – cont.

  • TRIN (true response inconsistency)

    • 23 pairs of items that are opposite in content

    • either T/T or F/F to assess acquiescent or non-acquiescent responding

    • larger raw scores = true responding while smaller raw scores = false responding

    • raw scores should be between 6 and 12 in order to consider the profile valid

  • Fb - back infrequency items for latter part

Coding the profile
Coding the Profile

  • List scale # codes in order of their T-score elevations (from highest to lowest)

    • usually only interpret 4 scale codes and order does not matter

  • Welsh coding system involves adding symbols to numerical scale codes

    • e.g., L F K 1 2 3 4 5 6 7 8 9 0

    • T 57 75 43 69 88 75 94 52 81 75 79 59 65

    • Welsh: 4268371095 FLK

Codes listed to the right
Codes (listed to the right)

  • ** 100-109, * 90-99, “80-89, ‘70-79, +65-69, -60-64, /50-59, .:40-49, #30-39

  • Some coding forms use ! to denote scores of 110-119 and !! for 120 or greater

  • Underline identical T-scores (and list in ascending order) as well as those within one point of each other

  • e.g., 4*26”837’10+95/ F’L/K.:

  • Code Types 2,3 and 4 point codes: 5 point diff between lowest code T and T of highest scale not in the code.

Mmpi 2 practice case m s
MMPI-2 practice case: M.S.

  • Integrate the MMPI-2 data with the client information (vs. laundry list). Note: profile valid.

    • e.g., profile 3-2/2-3 should revolve around the discussion of depression and the manifestation of symptoms (physical symptoms tend to be substituted)

      • How does this relate to M.S.?

      • Recent loss, seeing her physician, isolation

    • What does the 8 (or 2-3-8) tell you?

      • How might psychotic symptoms relate to M.S.?

      • Confusion from malnutrition, confusion as a result of depression, her age re: dementia? All are possible

M s continued
M.S. - continued

  • Include discussion of (or section on) prognosis, recommendations, and diagnosis

    • Axis I: 296.24, Major depression, single episode, with psychotic features

    • AXIS II: No diagnosis (or deferred)

    • AXIS III: Malnutrition, dehydration, poor hygiene & personal care

    • AXIS IV: Death of spouse (Severity: extreme (acute event)

    • AXIS V: GAF: Current, 24; highest past year, 52

Mmpi 2 with other pops
MMPI-2 with other pops.

  • MMPI was originally developed using Caucasian groups of patients

  • Although some research has shown mean score differences between majority and minority groups, this is less relevant to the issue of whether there is differential predictive validity (few studies on this)

  • Hall, Bansal, & Lopez, 2000, have conducted a meta-analysis of 30 years research on minority groups and the MMPI (both versions)

Hall et al 2000 summary
Hall et al., 2000 - summary

  • AA – first note that cultural identification moderates all findings (cf. acculturation)

  • Inconsistent findings re: mean differences, with F, 8, & 9 sometimes higher by approximately 5 T-score points

  • Many matched grouped studies of patients have found no differences, though Ns were small (meaning what?)

  • Generally no differences in predictive validity that achieve statistical or clinical significance and any differences can be attributed to SES and age

  • MMPI-2 has representative norms

  • Minimal information on the supplemental scales and even less for the content scales

Hall et al 2000 sum cont
Hall et al., 2000 – sum cont

  • Hispanics likewise show few differences from Caucasians

  • Possible differences for scales 3 and 0, with Hispanics scoring higher on 3 and lower on 0, but these effects were small with minimal clinical or statistical sig.

  • Much stronger effect for acculturation in this ethnic group

  • Few studies on Native Americans, but they show this pop. to score slightly higher on most scales

  • Few studies for Asian Americans, and they show slight elevations for scales F, 2, & 8.

  • Generally valid to use for these pops given appropriate acculturation and understanding of the language

Other populations
Other populations

  • Given its original construction, there should be no problems using the MMPI in medical settings

    • Medical problems do not necessarily result in higher scores (i.e., more distress)

  • In substance abuse settings, no profile emerged to detect substance abuse, but scale 4 was a good predictor (see also the supplemental scales)

  • We will discuss forensic applications later in the semester (see chapter 13)

  • MMPI-2 can be used in non-clinical settings to screen for psychopathology, but there are some concerns.

    • False positives are more common

    • Has not been validated to predict success in other settings (e.g., jobs) which is true of most personality tests (predict interest)

Mmpi a 1992
MMPI-A (1992)

  • Do we need a different inventory for adolescents? Why? Scales of concern?

    • M/F for adolescents may be less defined

    • Theoretically Pd is thought to be elevated, but actually it tends to be lower

    • Personality is less stable overall so we need different norms to better interpret scores and relevant items for this age group

  • Valid for those aged 14-18 (for 18 y.o., the decision is based on life circumstances; e.g. at home? working?)

    • Important to score on both adult and adolescent norms as there can be substantial differences (T-score shifts of 15 points)

  • 478 items (some new some from the original inventory)

  • written & auditory forms both in English and Spanish

Mmpi a

  • Includes all of the clinical, & some new supplemental & content scales. So we use basically the same scales but different descriptors (i.e., a high score on Hs will not mean exactly the same thing for the MMPI-A; e.g., Pd equates more with acting out)

  • Biggest change was with the F scale since it is a norm defined scale (we need new norms)

  • Norms: 805 boys & 815 girls aged 14-18 solicited randomly from schools in 7 states. Represents the U.S. for SES and ethnicity (again minimal diffs for ethnicity)

  • Change from MMPI which had separate norms for different adolescent age groups (now only one)

  • F scale now has 2 parts: F1 = 1st part of test, F2 = 2nd part (F=total)

Mmpi a new scales
MMPI-A: New scales

  • New Supplemental scales:

  • Alcohol/drug problem proneness (PRO) – empirically derived to assess the likelihood of alcohol or other drug problems. Items differentiate adolescents in tx from those having other psychological problems

  • Alcohol/drug problem acknowledgement (ACK) – face valid items that reflect the admission of problems

  • Immaturity (IMM) – reporting behaviors, attitudes, and perceptions that reflect immaturity (e.g., poor impulse control, judgment, and self-awareness). Items predict academic problems and cognitive limitations.

  • Check for diagnoses such as oppositional-defiant, conduct disorder, and in adulthood ASPD

Mmpi a psychometrics
MMPI-A Psychometrics

  • For the most part, the psychometric properties of the MMPI-A are sound. The reliability values are lower than the MMPI-2 values, but still within acceptable limits.

    • Why might there be less temporal stability in the MMPI-A?

  • General interpretative data from the MMPI-2 can be generalized to the MMPI-A, but this data should be considered in light of the client’s position in life (i.e., consider how the scores relate to school life, problems with parents, need for independence, etc.)

  • Note: no K-correction for clinical scales even though a defensiveness score is calculated. So what are the clinical scale implications for a high K?

Mcmi iii millon 1990
MCMI-III (Millon, 1990)

  • 175 item scale assessing problematic personality styles and classic psychiatric disorders (drawn from the DSM)

  • In contrast to the MMPI, this scale was derived theoretically to match the nosology (taxonomy) of the DSM to facilitate diagnosis and intervention planning. Assumes that any assessment is theory driven (vs. MMPI which tried to be a theoretical)

  • The theory is grounded in evolutionary principles assessing 4 spheres: existence (from serendipity to an organized structure), adaptation (survival), replication (reproductive styles that maximize diversity), and abstraction (the emergence of competencies to foster planning).

  • Scored according to a polarity model. e.g., self vs. other orientation (reproduction), pleasure vs. pain (existential, or aim of, existence)

  • Illustration: Schizoid is marked by deficits in both pleasure and pain as indicated by the lack of emotion and apathy

Mcmi iii properties
MCMI-III properties

  • A brief inventory (175 items) that takes only 30 minutes to complete

  • 3 modifier scales that correspond to the validity scales

    • Disclosure = defensiveness

    • Desirability = favorable response set

    • Debasement = lying

  • 11 clinical personality patterns: schizoid, avoidant, depressive, dependent, histrionic, narcissistic, antisocial, aggressive (sadistic), compulsive, passive-aggressive, self-defeating

  • 3 scales denoting severe personality patterns: schizotypal, borderline, paranoid

  • 7 clinical syndromes: anxiety, somatoform, bipolar, dysthymia, alcohol dependence, drug dependence, PTSD

  • 3 severe syndromes: thought disorder, major depression, delusional disorder

Mcmi iii continued
MCMI-III- continued

  • Scales interpreted based on base rates for each dx and it assumes that disorders are interconnected (consistent with comorbidity data)

  • Initial studies had classification rates of 90%, but follow-up studies have been much lower (50% or less)

  • Validity data has been equivocal and the reliability data is likewise lower than the MMPI-2 (these are related, and both linked to number of items)

Cpi harrison gough
CPI (Harrison & Gough)

  • Developed at the same time as the MMPI and served as the personality test for the normal population (MMPI for the clinical pop.). Drew from a similar item pool.

  • 480 T/F questions (some overlap with MMPI and others are new)

  • Emphasizes more positive/normal aspects of personality

  • 3 validity scales: well being (normals asked to fake bad), good impression (normals asked to fake good), communality (popular/obvious responding that may reflect defensiveness and conformity)

  • 15 general scales assessing a wide range of traits such as intellectual efficiency, capacity for status, achievement via conformity

  • Grouped into 4 quadrants (factors): Norm favoring vs. norm doubting and externalizing vs. internalizing

Cpi continued
CPI - continued

  • CPI was revised in 1986 with norms based on 13,000 males & females

  • Most commonly used personality inventory overall

  • It has been replaced by the NEO-PI as most common in the last 15 years.

  • Psychometrically sound (reliability and validity coefficients are high and stable for different pops), but a very long instrument.

  • Also some question as to the need for validity scales in the normal pop.

    • Burisch suggests this is unnecessary provided; 1) no reason to lie, 2) knowledge of the construct(s), and 3) self awareness.

Neo pi costa mccrae 1985 1992
NEO-PI (Costa & McCrae, 1985, 1992)

  • Based on the empirically derived 5 factor model

    • Assumption that 5 factors can represent all of normal personality

    • Evaluated this model in a variety of contexts, with samples from all over the world and in different languages

    • Assumes that language is the best place to start examining how to describe behavior (132 Eskimo words for “snow” indicates it is a meaningful construct)

  • Neuroticism (emotional stability), extraversion, openness to new experience, agreeableness (quality of interactions) and conscientiousness (dutiful, organized).

  • 5 factors have been recovered from other inventories like the Myers-Briggs, 16PF, etc.

Neo pi

  • Full version is 220 items and has 6 facets for each of the 5 factors

  • Short form (NEO-FFI) has 60 items and provides factor scores only

  • Norms are available for adults, college students and adolescents (though minimal differences between the latter two groups)

  • Strong psychometric properties including very stable retest coefficients, internal reliability, and validated with other personality scales.

  • Can be used to predict job interests (though vocational inventories such as the Strong Interest Inventory are better suited for this), but they do not predict job success (same is true for interest inventories)

  • Often used for intuitive purposes and not empirically validated purposes (e.g., assume that a manager should be low on N and high on C vs. empirically testing this assumption with current managers)

Structure of affect and other issues
Structure of affect and other issues

  • Big two (PA/NA) vs. 5 factor

  • Bipolarity of affect (vs. orthogonality)

  • Temporal question for what defines affect vs. personality

    • Problem of temporal language (e.g., “at this moment”)

Measures of affect
Measures of Affect

  • Note: The EPI (Eysenck) likewise measures personality (extraversion and neuroticism) in the normal population, and these two factors are usually the first two to emerge in factor analysis.

  • These factors correspond to the Big Two affect constructs (PA and NA)

  • Note: most of these measures do not address validity of responding

  • Nevertheless, research suggests that these scales tend to be fairly accurate and reflect actuarial rates for affective disorders (5-9% of adult women and 2-3% of adult men)

  • BDI – published in 1961 and revised in ’74, ’78, and ’96.

    • Among the most commonly used inventories with a comprehensive manuals published in 1987, 1993, and 1996 (BDI-II)

    • Normed for adolescents and adults aged 13 and older. 21 items with items arranged in a Guttman approach (increasing order of severity)

    • Suicide potential in items 2 and 9. For dx of Depression see neurovegetative items

Bdi continued
BDI - continued

  • Internally consistent and reliabilities range from .48 to .86 for periods ranging from several hours to four weeks

    • Why are retest coefficients smaller?

  • No way to correct for faked scores

  • Validated extensively for use in clinical settings

  • BDI-II validated on 500 outpatients drawn from across the country and a student sample of 120

  • 1 week retest was .93 and coefficient alphas were .92 or higher

  • Average BDI-II scores are 3 points higher than the original BDI

  • BDI-II time frame for each item focuses on last two weeks to match the DSM criteria

Bai beck steer 1993
BAI (Beck & Steer, 1993)

  • 21 item symptomatic inventory

  • Items rated on a 0-3 scale

  • Validated for use for inpatient (N = 1,086), outpatient (N = 160) and college student samples (N=65).

  • Shows convergent validity with other measures of anxiety and some disciminant validity with depression measures (though they are correlated – sharing 10-25% variance)

  • Rapid self-report tool

Ces d radloff 1977
CES-D (Radloff, 1977)

  • Developed by NIMH for use as a screening tool in the general population (also in college and geriatric pops)

  • Optimal test for this purpose in this population

  • 20 likert type items focusing on the last week

  • Better than the BDI-II at differentiating among those experiencing lower levels of depression

  • Internal consistency is high (.85 in general pop. and .90 in patient samples).

  • Retest figures tend to be low (.48) but this is less relevant for this construct

  • A score of 16 is clinical cutoff and it assesses depressed affect, positive affect, somatic activity, and interpersonal functioning

Maacl r zuckerman lubin 1985
MAACL-R (Zuckerman & Lubin, 1985)

  • Originally published in 1965 and revised in ’85. (132 checklist type items)

  • Normed on over 1500 adults, 400 adolescents (approx. 90% Caucasian, 10% Black)

  • Scores for Anxiety, Depression, hostility, PA, and SS (the latter has very poor internal reliability)

  • A rapid assessment but not as good psychometrically

  • Can be used to evaluate states or traits and reliability figures are better (though not very high) for the latter

  • Scales don’t corr with social desirability and do converge with MMPI ratings

Behavioral assessments
Behavioral Assessments

  • Assumption: behaviors can reflect cognitions and emotions (e.g., FACS; Ekman & Friesen, 1978)

  • Proliferation of behavioral assessments with limited validity due to the assumption that behavior can be easily defined and that it represents a meaningful (typically underlying) construct e.g., sweating, pacing

  • How to improve behavioral assessments?

    • Identify the actual behavior being assessed (lip turned downward vs. sadness)

    • Habitual behaviors may indicate underlying condition

    • Acknowledge role of both traits and situations

Beh assessments cont
Beh assessments – cont.

  • Also influenced by factors such as social desirability (varies depending if one is aware of the assessment)

  • Difficult to organize and systematize behaviors (e.g., how does one smile equate with the absence of a frown re: depression?)

    • Very inconsistent findings regarding the organization of individual behaviors (even physical symptoms) via F.A.

  • Why might self-report and behavioral assessments not overlap? What does this mean?

  • Recall behavioral reactivity phenomenon – change in behavior as a function of its assessment

Physiological measures
Physiological measures

  • “Some people want to fill the world with silly physiological measures. And what's wrong with that?” (McCartney et al., 1976)

  • Biofeedback – long history but very mixed findings

  • Plethysmography – changes in blood volume that may relate to emotional changes

  • Pupillary responses – attraction and fear?

  • Polygraph – arousal related to lying?

Cognitive testing refresher
Cognitive testing refresher

  • WAIS-III score interpretations for reports:

  • With regard to the index scores, which declines the most with age?

    • Quick, it’s PS!

  • Which show the greatest decrements secondary to organic dysfunction (trauma or disease)?

    • PS, WM, and PO: Depends on the area of the brain that is damaged. If diffuse, then all three. If temporal then WM, if more right hemisphere then PO.

  • Which is the best indicator of premorbid functioning?

    • VC (or subtests of vocabulary, similarities & info.)

      • Overlap with maturity? Less complex presentations?

      • What PD is associated with extremist thinking (splitting), inability to recognize subtleties?

  • Other implications?

    • Ease of use for clients, alternative test format, wider range of responses (variability), alternative approach to detecting pathology, difficult for client to identify socially desirable or undesirable responding, theory based

    • Defensiveness strategies (see MMPI-2)?

Projective test technique
Projective test/technique

  • MMPI/MMPI-2 is most frequently used test in inpatient settings

  • Rorschach & TAT are not too far behind

  • Advantages of projectives?

  • Disadvantages of projectives?

    • Administration and scoring is generally less standardized so reliability and validity are compromised

Minimal criteria for a test
Minimal criteria for a test

  • Standardized administration

    • Rorschach has numerous administration procedures (Bleck, Klopfer, Exner, etc.)

  • Standardized scoring

    • Rorschach has numerous scoring approaches (Bleck, Klopfer, Exner, etc.)

  • Standard of comparison for interpretations (norm group)

    • Minimal information with regard to representative norms

Exner s scoring system
Exner’s scoring system

  • Location – part of the blot

    • W, D, d, S, (WS)

    • How common is the location (normative comparisons from manual)

  • Determinant – what led to response

    • Form, Color, FC or CF, Movement, etc.

    • Evaluate form quality (normative decision based on manual of responses). Low F+% = psychosis/poor reality contact

  • Content – focus on what specifically

    • Human or animal, whole or detail, nature, etc.

  • Populars – determines normative responding

Rorschach exner
Rorschach – Exner

  • Exner’s (1987) scoring system involves an attempt to increase validity by objectifying the scoring, increasing the number of responses (14), and standardizing the administration

  • This has resulted in significant improvements in the test’s reliability and validity

  • In a meta-analysis, Hiller et al. (1999) found the Rorschach (using Exner’s scoring) to have larger validity coefficients than the MMPI-2 for studies using objective criterion variables

Other projective tests
Other projective “tests”

  • TAT (Thematic apperception test, Murray)

    • Stimuli are less ambiguous than the ink blots

    • Tell a story, though little standardization re: which pictures to be used, scoring (typically a content analysis), etc.

    • Used extensively with less literate pops like children (CAT), geriatric pops (GAT), non-English speaking individuals, etc.

  • Draw-a-figure test (figure drawings)

    • Person, family, house, tree, etc. – all are interpreted as you

    • Minimal standardization for scoring

  • Sentence completion

    • Sentence stems like “Mom is”, “Life”, etc. largely scored for a thematic standpoint

  • Bender-Gestalt (the same test used for neuropsychological screens)

    • Copying figures and making personality interpretations

Assessment of malingering
Assessment of malingering

  • What is malingering? What must it include?

    • Intentional? Awareness? Personal gain?

  • Very complex phenomenon that may change over time

    • e.g., A lie (or lies) that become “real/true” for the individual over time, or a truthful statement that becomes a lie.

    • Most statements can’t be categorized as one or the other, and typically involve aspects of both

    • Berry et al (1995) suggest that faking good and faking bad are distinct constructs (not opposite ends of the same continuum)

    • Harder to detect specific faking vs. general faking

    • Content nonresponsivity (CNR) – random responding, all true or all false

    • Content response faking (CRF) – fake good or bad; research suggests that these may be independent dimensions (client may fake good on some parts and fake bad on others)

  • Should always be considered (in some form) when there are contingencies for the patient

Classifications of misrepresentation
Classifications of Misrepresentation

  • Are symptoms under conscious control? Are physical/psychological symptoms motivated by internal or external gains?

  • Factitious Disorders – intentional production of symptoms (feigning) that are motivated by internal gains

    • Motivation is to assume the “sick role” as there are no external incentives for the behavior (e.g., economic gain, avoiding legal responsibility, etc.)

  • Somatoform disorder – unintentional (i.e., unconscious) production of symptoms for internal gains

  • Malingering – intentional production or exaggeration of symptoms (i.e., conscious) motivated by external incentives

    • Lack of cooperation during the evaluation, presence of ASPD, discrepancy between self-reported data and objective findings, medicolegal context for referral (e.g., attorney, police, etc.)

    • Note: Exaggeration rather than fabrication makes differential very difficult

Pros and cons of malingering dx
Pros and Cons of Malingering Dx

  • What are the costs of labeling someone a “malingerer”

    • Questions all present and future clinical presentations

  • What are the limits of our measures to make this differential?

  • After weighing the strength of any claim of malingering (relatively weak given the limits of our measures) and the costs of making an erroneous judgment, we need to act very carefully

  • Use converging, independent evidence to make any determinations

    • e.g., objective inventories like the MMPI-2, strong contextual factors (i.e., to provide the motive and baserates), interview, low probability baserates for responding (e.g., incorrect on all options when this would be well below chance responding), and response to the evaluator’s feedback (e.g., “Actually, you’re doing quite well” – followed by decrements in performance)

Mind of a murderer the bianchi tapes
Mind of a murderer – the Bianchi tapes

  • Identify the circumstances that could be seen as contingencies for malingering (reinforcers for malingering)

  • Why would that particular malingering behavior be manifested?

  • How could client have obtained the information necessary to provide the malingering profile? Any evidence that this information was obtained?

  • Any indications of malingering in his presentation? (Be objective)

  • What are some reasons why he might not be malingering?

  • Predict response sets in advance of testing (vs. scoring in hindsight)

  • What pattern of responses do you predict for the Rorschach?

  • What pattern of responses would you predict for the MMPI-2?

  • What’s your call?

Measures of malingering berry et al
Measures of malingering – Berry et al

  • The pasta strainer and photo copy machine “incident”

  • MMPI-2: F, F-K (note: these two indices are not independent), VRIN (random), TRIN (all true or all false), and Fb

    • Also look for discrepancies between some of your subtle and obvious supplemental scales (though this can also just assess sophistication in malingering)

    • The D scale has also been used with some success, as the items appear to reflect a less sophisticated (popular) view of mental illness

  • MCMI – evaluates random responding, low frequency responding, willingness to disclose information, debasement (willingness to endorse psychological problems), and desirability (unwilling to endorse psychological problems). Also as with the D scale of the MMPI, the well-being scale can likewise assess psychopathology

Measures of malingering 2 continued
Measures of malingering – 2 continued

  • CPI (Cough, 1957) – intended to assess personality in the normal population

    • Has 3 validity scales: good impression (faking good), communality (items with either very high or very low endorsement frequency that assesses random responding), well-being (assesses fake bad)

  • Basic personality inventory (BPI: Jackson, 1989) contains 12 scales each with 20 T/F items. Research is limited on its utility for this.

    • Deviation scale is comparable to the MMPI-2 F scale

  • Personality assessment inventory (PAI: Morey, 1991) is a 344 items

    • 4 validity scales: Inconsistency, infrequency, negative impression management and positive impression management

  • NEO-PI-R (Costa & McCrae, 1991) – no effective validity index, so should not be used in this context

  • 16 PF also lacks adequate validity measures and should not be used

Measures to specifically detect malingering
Measures to specifically detect malingering

  • These measures should be administered when the referral question specifically implicates malingering and/or when there are substantial contingencies to suggest that malingering is likely

  • Structured Interview of reported symptoms (SIRS)

    • Has shown some promise, though it is susceptible to acquiescence and false positives (claiming malingering when it is not)

  • The M test is a 33 item T/F test with three scales: genuine symptoms of schizophrenia, atypical attitudes not characteristic of mental illness, and bizarre and unusual symptoms rarely found in mental illness

    • Showed some ability to differentiate patients from directed malingerers and from suspected malingerers (Note: The problem with using the latter criterion group as there is no definitive knowledge about those individuals)

Measures to specifically detect malinger 2
Measures to specifically detect malinger. - 2

  • Test battery approach including WAIS-III and the MMPI-2 – the more tests administered, the harder it is to present a consistent profile

  • This approach should use baserates for incorrect responses as the primary means of classifying (see also TOMM)

    • Provide response options (typically no more than two) such that a chance correct criterion can be calculated (e.g., 50% for a two item version) – this should be no lower than 30% to avoid floor effects

    • Track responses over at least 30 trials (the more the better as this minimizes chance outcomes).

    • Calculate the probabilities for deviations from .50 correct and apply it to client’s correct response rate (i.e., what are the odds that they would have missed as many as they did if they were truly guessing)

    • Evaluate responsiveness to your feedback (e.g., “You’re actually not doing that bad” vs. “Most people with your type of injury do better”)

    • If less sophisticated malingering there will be an immediate and relatively large response to your comments

Who is your client
Who is your client?

  • Why is this question important in addressing the malingering issue?

  • If the suspected malingerer is your client who is undergoing therapy with you (or someone else) to whom is your obligation and what are the costs/benefits of undertaking an evaluation of malingering?

    • Does it help the therapeutic process? Focus on why one might be deceptive to better understand client’s behavior

  • If the “client” is the court, then to whom is your obligation and what are the costs/benefits of undertaking an evaluation of malingering?

    • Question now is to determine if client is being deceptive/evasive.

Assessing psychopathic personality
Assessing psychopathic personality

  • Psychopathic personality = behavior characterized by remorseful and callous disregard for others and a chronic antisocial lifestyle. Thus, most ASPDs are not necessarily psychopathic.

  • Drawing data from various sources (at least three)

    • In person interview

    • Testing

    • Independent historical information (anything that is not self report – it is important to note that other official records are not necessarily based on anything other than self-report)

  • Although all three of the above are important in order to provide converging evidence, the test data will be the strongest tool in court (due to its psychometric strengths)

Assessment meloy gacono 1995
Assessment (Meloy & Gacono, 1995)

  • The Psychopathy checklist – revised (Hare, 1991) – 20 item test with a 4-point Likert scale response format. Largely intended for males (little data on females)

    • To be completed by the clinician after a clinical interview and review of historical data (includes descriptors falling under a single dimension of psychopathy) e.g., impulsive, irresponsible, shallow emotions, etc.

    • Items must be scored in a particular sequence, with more structured items first, followed by the least structured items (with the former contributing to the latter)

    • Cutoff score of 30 or greater to define psychopathy, with higher scores denoting more extreme presentations

    • Adequate reliability and validity, though note the overlap between some of the validity criteria and the info used to determine the score (e.g., extent of criminal record is used for both)

Assessment meloy gacono 1995 p 2
Assessment (Meloy & Gacono, 1995) – p. 2

  • The Rorschach – should still pursue the minimum number of responses (14 or more) as suggested by Exner (1986)

    • Include an assessment of defenses and object relations (both of which appear to have modest reliability) that suggest more narcissism (self-references), violations of boundaries, etc. in the psychopathic personality (specific ratios from Exner’s scoring system are described)

  • MMPI-2 – primary focus is on scale 4 (also content subscales drawn from 4 – be cautious with the latter)

    • If administering scale 4 alone, note that you will not have the benefit of the k correction. Thus, scores will be suppressed.

    • L and F will also predict psychopathy (tendency to be untruthful)

  • Cognitive abilities (e.g., WAIS-III) are unrelated to the presence of psychopathy, but may be informative as to the nature of the presentation (e.g., level of sophistication, concordance with traditional/normative concepts of intelligence, etc.)

Integrity testing
Integrity testing

  • Evaluating integrity as a trait, whereas such behavior may be situation specific (e.g., someone who would not lie in interpersonal settings might not hesitate to cheat on their taxes).

    • Characterological view of integrity downplays situational factors

    • Integrity is a very broad concept that can include diverse responses (e.g., passive vs. active lying, cheating vs. theft, etc.)

  • Early paper and pencil tests were validated with the polygraph

  • Employed in low end entry jobs when people have to interact with money (retail, financial services, etc.)

  • Today, such tests attempt to predict a wide range of behaviors including violations of work rules, fraud, absenteeism, etc.

Integrity testing p 2
Integrity testing – p. 2

  • Overt integrity tests – evaluate beliefs about the incidence of theft and other counterproductive behaviors, punitive attitudes towards theft, endorsement of common rationalizations for theft, and direct questions about one’s own involvement in such activities.

  • Personality oriented measures – much broader than integrity tests and tend to have lower face validity (e.g., high conscientiousness on the NEO)

  • Clinical measures like the MMPI – validity scales

  • All are difficult to validate because the behavior we are trying to predict goes largely undetected. So if a test score does not predict it could just mean that this is a false positive or someone who was not caught

The polygraph test
The polygraph test

  • Measures physiological arousal that is presumed to be associated with lying. e.g., perspiration as indicated by galvanic skin response, brain activity suggesting arousal, etc. to the question (not answer)

    • Is this assumption reasonable?

    • Confounds?

    • Under what circumstances can lying not be associated with arousal?

      • Habituation effect from repeated lying?

      • Lack of awareness of the lying? (issue of conscious vs. unconscious)

  • What is the best way to quantify arousal? Should we evaluate this normatively or ipsatively?

  • Control Question Test (CQT) – compares relevant questions to control questions which are intended to elicit a strong physiological response from innocent subjects (e.g., “Prior to 1993, did you ever do anything that was illegal or dishonest?”)

    • While innocent people know they didn’t commit the crime, they are either uncertain or lying about the CQ. Guilty persons should not respond as much to the CQ

The polygraph test p 2
The polygraph test – p. 2

  • Criticisms of the CQT

    • Difficult to develop good control questions that will produce similar responses relative to relevant questions for innocent people. This results in many false positives (Note: Bias for positive outcome is why most of these tests have artificially high success rates in forensic settings – most are guilty)

    • CQ are designed for each individual, so standardization is compromised

  • Direct Lie Control Test (DLCT) – if person answers truthfully to a question they are asked the question again and told to lie about it when asked again (a known lie for comparison)

    • Can be standardized and the power of the DLCT is from the instruction (which is standardized) not the content of the question

    • Can reduce the rate of false positives and generally does better than the CQT

  • Initially employed absolute standards for arousal = lying and this was not at all effective

The polygraph test p 3
The polygraph test – p. 3

  • The guilty knowledge test (GKT) – not designed to detect deception, rather it tries to differentiate between those who have knowledge about a particular event (crime) and those who do not (the innocent)

  • The concealed information test (CIT) – is similar to the above approach and likewise tries to assess familiarity with specific information as opposed to lying

  • Both of these approaches have the advantage of asking the exact same questions of all individuals and comparing responses both within and between subjects

  • Minimal data on these approaches, as the bulk of the research is on the CQT

Does it work
Does it work?

  • Honts (1994) reviewed the literature on the effectiveness of the polygraph and found that it does about as well as chance in experimental settings. Most of the reviewed research uses the DLCT

  • In real life and experimental settings, the majority of errors are false negatives (saying someone is innocent when they are guilty)

  • Most deceptive individuals (up to 95%) are misclassified

  • Because the cost of a false positive (saying someone is guilty when really they are innocent) is deemed to be higher in our legal system. Therefore, the cutoff scores (criteria) have been altered so as to make false negatives more likely

  • Why does it fail?

    • If high arousal to control questions, then more difficult to discriminate

    • Idiosyncratic responses to lying

Admissibility of the polygraph saxe ben shakhar 1999
Admissibility of the polygraph (Saxe & Ben-Shakhar, 1999)

  • Courts have almost universally rejected the polygraph, though this question has been and continues to be litigated extensively

  • Courts are increasingly being made responsible for evaluating the merits of test data, despite lacking the expertise to do so.

    • Note: The literature has become increasingly discrepant in its view on the polygraph (disagreement on its validity even in the scientific community)

  • What criteria should be used to evaluate this information and what should we tell the courts?

  • History

    • Marston (1917) used a blood pressure cuff to determine truthfulness (arousal) in a defendant (Frye), based on the assumption that while truth required little or no energy, lies do – rejected by the courts

History of the polygraph
History of the Polygraph

  • Note the courts use of the term “experimental” as “not well established evidence”

  • The Frye ruling adequately reflects the courts treatment of the polygraph even today, though now based on the Federal Rules of Evidence (FRE) which require that the evidence (polygraph or otherwise) be relevant and that it aid the jury (i.e., be valid).

  • Daubert (1993) was based on the FRE and highlights 4 considerations when ruling on evidence:

    • Testability or falsifiability (see Popper and the method of science)

    • Error rate

    • Peer review and publication

    • General acceptance

  • This basically requires juries & judges to evaluate scientific issues

History of the polygraph p 2
History of the Polygraph – p. 2

  • In trials like Daubert, scientists with opposing views on the polygraph present their views and the jury must decide on the merits of their arguments

  • Generally there has been no legal distinction between the concepts of reliability and validity (you can see where this is go, since, from a scientific standpoint, reliability limits validity)

  • An additional problem with these concepts is that the data is collected as a series of discrepancy scores and these are then summed to reflect a qualitative assessment of truthful, deceptive, and inconclusive. Thus, very different discrepancy readings might still result in similar qualitative assessments.

  • Two accepted approaches for reliability are:

    • Test the same person twice on the same issue using the same polygraph technique with 2 different testers

    • Test the person once, but have the chart scored by two different people

History of the polygraph p 3
History of the Polygraph – p. 3

  • The latter approach deals on with the error involved in chart scoring and ignores (or equates) administration error

  • The real issue is whether the procedure as a whole is reliable (e.g., the creation and administration of control questions), thereby getting at internal reliability (do different parts of the test agree), test retest reliability (different administrations of the test agree), inter-rater reliability (different test administrators agree as to the outcome)

    • Note: There are practical limitations to how often the “same” test could be given to the same individual

  • What little data exists on reliability focuses only on the between examiners approach (inter-rater reliability), though this reliability is reasonable (not high). Thus, this remains an unevaluated component of the polygraph (major limitation)

History of the polygraph p 4
History of the Polygraph – p. 4

  • Because the courts do not distinguish between reliability and validity, the minimal reliability that does exist carries far more weight than it should.

  • Modern views of validity highlight the integrative component of validity (recall Messick, 1995), though to evaluate it, it is necessary to consider different aspects separately

  • Different types of validity are more relevant depending on the question at hand

    • e.g., predictive validity for integrity testing in job placement/hiring, vs. criterion validity being more relevant for determining truth/lying

  • Construct validity gets at the theoretical issue of what is a lie. Is it a situational phenomenon or a trait? Can it be represented by physiological responding? Etc.

    • No theory to explain why a stronger response should occur for lies vs. truth

History of the polygraph p 5
History of the Polygraph – p. 5

  • Similar physiological responses to lying appear to occur for experiences such as surprise/novelty

    • Note: For the CQT, questions about the crime are expected to be well rehearsed for the criminal

  • Thus, they have questionable construct validity (not necessarily measuring what they propose to measure)

    • Under-represents the construct of interest and over-represents irrelevant constructs (surprise, stress, etc.)

  • What criterion can be used?

    • Outcome of a trial? If the case is dismissed?

    • Do either of these assure that we know the client’s status re: lying?

  • Note also that a true evaluation of the polygraph would mean that the examiner only has access to the polygraph data (that s never the case).

History of the polygraph p 6
History of the Polygraph – p. 6

  • The criterion and predictor are rarely independent.

    • e.g., if the polygraph is used to get a confession and the confession helps get a conviction, then by definition, the polygraph is part of the criterion (polygraphs are frequently used to get confessions)

  • Experimental criteria for the polygraph generally lack external validity (is lying in an experiment = to lying in a crime involving yourself? That is, are all types of deception equal?), while real life evaluations of the polygraph lack experimental rigor and control (e.g., only a subset of them will ultimately have a clear outcome regarding deception and this may not be representative of all respondents).

  • The CQT assumes that you can create similar “control” questions.

  • Do deceptions involving different types of crime result in the same physiological response?

Issues in assessing alcohol substance abuse
Issues in assessing alcohol/substance abuse

  • Recognition of dual diagnosis (vs. assuming all other problems are merely secondary to the addiction) – How can we address this?

  • Timing of assessment remains an important concern as this can dramatically alter the outcome- When is the optimal time to assess?

  • Patterns of use/abuse and general categories (e.g., stimulants, sedatives, etc.) of use may be important to assessment and intervention

    • Also some drugs may be used to offset the deleterious effects of other drugs

  • Context in which use typically occurs may help in identifying triggers and high risk settings for potential relapse – Examples of assess & tx?

  • Motivation for seeking treatment is likewise a critical component to evaluating the patient – Why? How would you assess and tx differently?

    • e.g., legal motivation, social/family pressure, work requirement, etc.

  • May require different test features to identify those still using as opposed to those who have used before but are not now using

  • The outcome of research in this area varies greatly as a function of how use is defined (any use, quantity/freq, problem behaviors, combos., etc.)

    • May identify different pops (e.g., those with liver damage vs. those losing jobs)

Specific measures to assess alcohol and drug abuse
Specific measures to assess alcohol and drug abuse

  • The MMPI-2 has 2 items (264 “I have used alcohol excessively” & 489 “I have a drug or alcohol problem”) that directly assess use, but the small number of items limits their psychometric properties.

  • These items each appear to identify very different groups

    • Sensitivity (how well the test identifies those who abuse alcohol) of approx. 80% for males and 75% for women

    • Specificity (how well the test identifies those who do not abuse alcohol) ranges from 53% to 95% for men and from 76% to 97% for women (varying on the item and race of the respondent)

  • Because the lifetime prevalence base rates for use in the population are 8% for women and 16% for men, it is difficult to improve on the base rate of non-use (84% or more)

  • Other measures include the MAST and the CAGE – what do you know about these?

    • Both have problems identifying female substance abusers (they were developed for and validated on, men)

Specific measures to assess alcohol and drug abuse mmpi 2 scales p 2
Specific measures to assess alcohol and drug abuse: MMPI-2 scales – p. 2

  • MacAndrew Alcoholism scale – (from the MMPI-2) is best for identifying white males who have a propensity for polydrug abuse. It has a sensitivity of approx. 70-75% and 20% false negatives.

    • Very high false positive rate for black males, little data on females and adolescents, and lower hit rates for psychiatric patients

  • Addiction Admission scale (also from the MMPI-2) – acknowledgment or denial of substance abuse problems

    • Low reliability

  • Addiction Potential scale (also from the MMPI-2) – personality features associated with use

    • Low reliability

  • MMPI-2 profiles associated with use: 2/4, 4/2, 2/7, 7/2, 9/4, 4/9,

    • Just males: 1/2, 2/1

    • Just females: 3/4, 4/3, 6/4, 4/6, 8/4, 4/8

    • Code types account for 25-35% of alcoholics & they don’t differ on tx success

Issues in alcohol drug assessment
Issues in alcohol/drug assessment scales – p. 2

  • Is there any utility in identify substance abusers who are doing so covertly or who don’t believe they have a problem?

    • Drawbacks: Treatment generally requires the clients willing consent, so why bother identifying anyone other than those who acknowledge use? This is consistent with the most widely used model, AA.

    • Some benefits: Accuracy of other diagnoses, as use can alter presentation of other symptoms, it can make some medication treatments undesirable due to interaction effects, it could bring a problem to a higher level of awareness for the client, etc.

  • Utility in administering a measure for some clients as it can serve as a standard (vs. an opinion) to the lay person, that allows for a normative evaluation

    • * Research suggests that exposure to norms can not only help with assessment, but also recognition of problem drinking

  • Use, in and of itself is considered problem use for an alcoholic from an AA perspective. What factors are relevant from a CD perspective?

Legal ethical issues in assessing children
Legal/ethical issues in assessing children scales – p. 2

  • Three components of “consent” for testing (anyone)

    • Knowledge – what will be done, why, and how

    • Voluntariness – absence of coercion; a child alone can’t do this, but they are usually asked for assent

    • Competence – parents must be legally competent and guardians to give consent for child

  • Also you are ethically (though not legally) bound to tell the parents of potential risks from testing (e.g., what test scores can be used for – such as being grounds to deny entry to a special education program)

  • Child is not likely to be the one who asked for testing. So are they the client? If not, who is?

  • Legal issues abound for intelligence testing, but there have been few precedents for personality assessment. Why?

Legal precedents
Legal precedents scales – p. 2

  • Griggs v Duke Power Company (1971) – job testing

  • Hobson v Hansen (1967) – racial disparity (problems with standardization & norms; assessed present skills rather than innate ability)

  • Larry P. v Riles (1972) – culturally biased IQ tests for EMR determination

  • PASE v. Hannon (1980) – reversed the Larry P. decision based on the fact that EMR determinations were based on more than just IQ testing (any thoughts on the item by item review by the judge?)

  • Lora v Board of Education City of New York – use of TAT, Rorschach, & Bender-Gestalt to label minority children as emotionally disturbed (vague def. for latter)

  • Note: Most personality tests are administered voluntarily. Test validation issues:

    • Tests must be validated for the purpose for which they are being used

    • Tests must be reliable for the pop being used, and appropriate norms must exist for that pop.

    • The tests must be capable of generating appropriate decisions for that pop (i.e., validity)

  • Note: many personality tests were developed for adults and co-opted for children. Which of the above issues is most affected?

Demers 1986 on testing
Demers (1986) on testing scales – p. 2

  • Although there are few legal challenges of personality tests, these measures do tend to have more problems with reliability and validity

  • Little to no evidence for gender or racial bias in personality testing

  • Also, most personality tests are administered in a voluntary context

  • Test validation issues:

    • Tests must be validated for the purpose for which they are being used

    • Tests must be reliable for the pop being used, and appropriate norms must exist for that pop.

    • The tests must be capable of generating appropriate decisions for that pop (i.e., validity)

Providing feedback to clients
Providing feedback to clients scales – p. 2

  • APA requires that feedback be provided after testing, but it must be in a form that they can understand (varies depending on the client)

    • This can be best accomplished through an overview of the findings and then a Q & A session.

  • The feedback should provide a clear path to treatment goals

  • Consider anything that is assessed as representing a continuum, such that any characteristic will be shared by some portion of the population

  • Terminology such as unique and different can be substituted for “abnormal”, “deviant”, or “pathological”

  • Client need not agree with your feedback. Objections can be used to clarify findings and as a starting point for the intervention

  • Have client summarize info. Back to you

Providing feedback to clients p 2
Providing feedback to clients - p.2 scales – p. 2

  • Feedback should also include information on the tests themselves (validity and reliability) in language that can be understood by the client

    • General psychometrics can be used to enhance the credibility of the test e.g., “The MMPI has been used for over 50 years by clinicians and it is one of the most widely used tests. Many research studies have been done to show that it is pretty consistent in the scores it produces and that it works pretty well at predicting behaviors.”

  • This issue may be further complicated when giving feedback to those with limited cognitive abilities, but a more detailed account can be provided to those who have legal guardianship

Providing mmpi 2 feedback to clients
Providing MMPI-2 feedback to clients scales – p. 2

  • Empirical evaluation of getting MMPI-2 feedback

  • Compared MMPI-2 feedback of college students relative to attention with no feedback

  • The former showed increased self-esteem, immediately & after 2 weeks

  • Decreased symptomatic distress, immediately and after 2 weeks

  • Why would this occur?

    • Nature of the client population? (higher functioning, therefore feedback is likely to be generally positive?)

    • Selective sampling? (Those seeking out personality evaluations are wanting feedback and are more likely to construe it positively?)

  • When initially meeting with clients and discussing the testing and the eventual feedback you will be able to differentiate those who will be most/least receptive to the feedback

    • Highlights the importance of having the client arrive at the decision to test

Dsm iv codes
DSM-IV codes scales – p. 2

  • The parenthetical term “(provisional)” may follow a diagnosis to indicate a significant degree of diagnostic uncertainty

  • The phrase “rule out” is used to denote other diagnoses that should be considered and that are still to be ruled out.

  • The numeric code should follow the AXIS number and then the formal name of the disorder should be listed.

    • e.g., AXIS I: 295.40 Schizophreniform disorder (Provisional, rule out Organic Delusional Disorder), with(out) good prognostic features.

  • Numeric codes from the DSM are matched to the ICD (International Classification of Diseases) codes to allow for international compatibility.

  • Recording procedures: e.g., Major Depressive Disorder

    • AXIS I: 296.34 - 4th digit is either 2 (single episode) or 3 (multiple) -5th digit is severity: 1 = mild, 2= moderate, 3 = severe without psychotic features, 4= severe with psychotic features, 5= partial remission, 6= full remission

    • 4th and 5th digits typically apply to most recent or current episode

Dsm iv codes continued
DSM-IV codes - continued scales – p. 2

  • Recording procedures: e.g., Bipolar I disorder

    • AXIS I: 296.34 - 4th digit is 0 (single episode). For recurrent episodes, it’s 4 if current or most recent episode is hypomanic or manic, 5 if depressive, 6 if mixed, 7 if unspecified.

      -5th digit is severity: 1 = mild, 2= moderate, 3 = severe without psychotic features, 4= severe with psychotic features, 5= partial remission, 6= full remission, 0 = unspecified (except for hypomanic where 5th digit is always a 0, and unspecified, where there is no 5th digit).

  • For Bipolar II, the 4th digit coding is the same, but do not use the 5th digit code as is already specified as 9.
