Rating scale
Rating Scale

  • Measurement instrument used to elicit a rating.

    • A rating is a systematic estimation of some attribute of a person, object, or event along some dimension (e.g., degree of agreement about finances)


Individualized rating scale irs
Individualized Rating Scale (IRS)

  • Scales for rating the degree, magnitude, and intensity of problems identified for individual clients

  • Tailor-made for each client

  • Also known as a “target complaint scale”


Constructing irs s
Constructing IRS’s

  • Identify and define problems

  • Select rating dimensions

  • Select number of response categories

  • Select rating scale anchors

  • Create equidistant response categories

  • Select time period, event, or situation

  • Set goals


Identify and define problems
Identify and Define Problems

Identify, conceptualize, and operationalize problems


Select rating dimensions
Select Rating Dimensions

  • Quantitative quality or property (i.e., attribute) of a person, object, or event

    • Quality of social support or of time spent with a spouse, children, or friends, etc.

    • Degree of impairment caused by self-injurious thoughts, panic attacks, alcohol consumption, illegal drug use, or diabetes, etc.

    • Severity of drug or alcohol cravings, stress, self-deprecating or intrusive thoughts, or tension or migraine headaches, etc.


Select number of response categories
Select Number of Response Categories

  • Point on a rating scale that represents the degree, magnitude, or intensity of an outcome

  • Can influence reliability and validity

  • Large enough to detect important differences, but not so large that it is difficult to distinguish among categories

  • 7 plus or minus 2 (i.e., 5 to 9)


Select rating scale anchors
Select Rating Scale Anchors

  • Brief (usually) explicit labels, descriptions, or examples used to define points or numbers on a rating scale (e.g., 1 = poor, 2 = fair, 3 = good, 4 = very good, 5 = excellent).

  • Define numbers

  • Higher numbers should represent more of the dimension measured

  • Anchors should be congruent with the problem being rated


Select rating scale anchors cont d
Select Rating Scale Anchors (cont’d)

  • Individualized or generic anchors

  • Generic anchors can be applied to a wide variety of problems and clients allow comparability across problems

  • Individualized anchors may be more relevant and meaningful to clients


Create equidistant response categories
Create Equidistant Response Categories

  • Makes it easier to evaluate change

  • View as a thermometer


Select time period event or situation
Select Time Period, Event, or Situation

  • Certain time at the end of each day or week

  • In response to a certain event or situation such as after an interaction with a particular person


Set goals and objectives
Set Goals and Objectives

  • Point on the scale that the client, you, or a relevant other hopes to achieve

  • Percentage change


Decide who where when and how often to collect data
Decide Who, Where, When, and How Often to Collect Data

  • Select respondent(s)

  • Decide when and where to collect ratings

  • Decide how often to collect ratings


Who?

  • Clients

  • Practitioners

  • Relevant others

  • Independent evaluator


When and where
When and Where?

  • Representative times and conditions

  • Conditions conducive to accurate measurement

  • Standardize times and conditions


How often
How Often?

  • Regular, frequent, pre-designated intervals to monitor clients’ progress, before, during, and after intervention

  • Often enough to detect significant changes, but not so often that it burdensome to the rater or intrudes on intervention efforts


Engage and prepare clients
Engage and Prepare Clients

  • Be certain the client understands and accepts the value and purpose of monitoring progress

  • Discuss confidentiality

  • Present measures with confidence

  • Don’t ask for info the client can’t provide

  • Be sure the client is prepared

  • Be careful how you respond to information

  • Use the information that is collected


Advantages of irss
Advantages of IRSs

  • Can be completed by clients, practitioners, relevant others, or independent evaluators

  • Tailored to individual clients

  • Flexibility in the type of problem

  • Measure the degree, magnitude, or intensity of problems

  • Easy to use, and so can be used frequently

  • Easy to interpret


Precautions in using irss
Precautions in Using IRSs

  • Consider behavioral observation when interest is in measuring the duration or frequency of a behavior

  • Consider standardized scales when interest is in measuring a construct with general relevance to different clients
