Introduction

 * What are the acronyms? What do they stand for?
 * What is the purpose of the measure?
 * What is the intended population of the measure?
 * How long does it take to take/administer the assessment?
 * Who wrote the measure?
 * How many items does the measure contain?
 * What kind of impact did the measure have?
 * Ex: is it more sensitive than existing measures?
 * What kinds of settings is the measure most typically used?
 * Ex: research, clinical

Versions

 * How many versions of the measure are there?
 * What is the intended population for each version?
 * How many items are in each version of the measure?
 * What are the acronyms for each version?

Reliability
Reliability refers to whether the scores are reproducible. Unless otherwise specified, the reliability scores and values come from studies done with a United States population sample. Here is the rubric for evaluating the reliability of scores on a measure for the purpose of evidence based assessment.


 * What were the norms from the measure’s first publication?
 * IE what was the demographics of the population used to first validate this measure?
 * What is the internal consistency?
 * Internal consistency: how well the items relate/correlate to one another
 * Normally reported as an alpha or Cronbach's alpha
 * What is the inter-rater reliability?
 * Inter-rater reliability: how consistently the measure gives the same results across different raters (*not applicable for self-report*)
 * Normally reported as kappa
 * What is the test-retest reliability?
 * Test-retest: how consistently the measure gives the same result after the same person takes the test multiple times

Validity
Validity describes the evidence that an assessment tool measures what it was supposed to measure. There are many different ways of checking validity. For screening measures, diagnostic accuracy and discriminative validity are probably the most useful ways of looking at validity. Unless otherwise specified, the validity scores and values come from studies done with a United States population sample. Here is a rubric for describing validity of test scores in the context of evidence-based assessment.
 * What is the content validity?
 * Content validity: how much the items relate to what you are trying to measure
 * What is the construct validity?
 * Construct validity: how well the assessment is able to measure the abstract concept  it is trying to measure
 * Ex: An ADHD assessment with good construct validity correlates very highly with ADHD diagnoses
 * What is the discriminative validity?
 * Discriminative validity: how well the measure does NOT measure what it is NOT supposed to measure
 * Ex: An ADHD assessment with high discriminative validity would not measure severity of schizophrenic symptoms
 * What is the prescriptive validity?
 * Prescriptive validity: Refers to the capacity of an assessment to inform which intervention will have the best outcomes for a client
 * What is the validity generalization?
 * Validity generalization: how well the validity of the measure holds true across different populations
 * Ex: a measure that has been validated in multiple languages and has high validity with college students, as a self-report, and as a caregiver report would have good validity generalization
 * Is the measure sensitive to treatment? How sensitive?
 * IE: can you use this measure throughout the course of a treatment to see if the treatment is working?
 * What is the clinical utility of the measure?
 * IE: does this measure ultimately help clinicians and clients?
 * Ex: if the measure costs a lot of money to take, is long, cumbersome, and has low validity/reliability, then it would have low clinical utility

Development and history

 * Why was the instrument developed? What need did this instrument meet? When?
 * How was the scale developed? What was the theoretical background behind it?
 * If there were previous versions, when were they published?

Impact

 * What was the impact of this assessment? How did it affect assessment in psychiatry, psychology and health care professionals?
 * What can the assessment be used for in clinical settings? Can it be used to measure symptoms longitudinally? Developmentally?

Use in other populations

 * How widely has it been used? Has it been translated into different languages? Which languages?

Research

 * Any recent research done that is pertinent?

Limitations

 * What are some of the measure’s limitations? Be thorough in your explanation.
 * Ex: does it have low reliability? Is it a self-report measure?
 * Is the measure copyrighted?
