Introduction
Introduction questionnaire:

Severity Indices for Personality Problems (SIPP)

Verheul, Andrea et al, 2008

Recently developed self-report questionnaire

Dimensional measurement for severity of personality functioning -> relevant towards DSM-V

Previous research: concurrent validity when comparing PD patients with a non-clinical population

Also useful as a dimensional instrument within a clinical population?

Verheul, Andrea et al, Psychol Assessment 2008, 20, 23-34


Objective method
Objective & method questionnaire:

Is the dimensional assessment of the severity of personality pathology (SIPP)

associated with

other indices of the severity of personality pathology

in a clinical population?

Dimensional measurement

of severity

of personality pathology

Facets (subscales) SIPP

Other Indices

of severity of

personality pathology

DSM-IV based measurements:- Presence BPD- Number of PDs- Number of BPD criteria- Cluster A PDs


Study population
Study Population questionnaire:

  • SCEPTRE study: N=2078 patients referred to centers offering psychotherapy for personality problems

  • Structured Interview for DSM-IV Personality (SIDP-IV): N=379 patients (18%) with BPD - 79.2% female, mean age 30.47 (sd 7.85)- Dimensional scores 16 SIPP facets


SIPP questionnaire:

SIPP questionnaire:

118 items, 16 facets (subscales), 5 higher-order domains

Dimensional measurement of personality severity:

Lower score = more maladaptive level of functioning - higher severity

Higher score = more adaptive level of functioning – lower severity

Results sipp facets and bpd diagnosis
Results questionnaire:SIPP facets and BPD diagnosis

BPD diagnosis =

SIPP-scores more

maladaptive


Within the bpd population sipp scores associated with number of pds
Within questionnaire: the BPD population: SIPP scores associated with number of PDs?

Associations between SIPP

and DSM-IV severity Indices

for 10 (out of 16) facets

# BPD criteria

Cluster A PDs

Comparable pattern


Discussion (1) questionnaire:

  • Results (modestly) in support of the SIPP as a useful instrument for the dimensional assessment of severity among BPD-patients

    However….

  • Contrast within BPD-patients smaller than between BPD and non-BPD-patients

  • SIPP specific and sensitive enough??


Further research questionnaire:

  • Transition: DSM-IV -> DSM-V

    Proposal DSM-V:

  • Indicate level of personality functioning for a patient on the “Self and Interpersonal Functioning Continuum”

  • “Self”: Identity integration, Integrity of Self concept, Self-directnedness“Interpersonal”: Empathy, Intimacy, Cooperativeness, Complexity, Integration of representations of others

  • 5 levels: No/Mild/Moderate/Serious/Extreme Impairment

  • How are SIPP-scores related to this continuum?

  • Dimensional scores and/or cut-off scores? Specificity & sensitivity?
