CAPs-IDD: Characteristics of Assessment Instruments for Psychiatric Disorders in Persons with Intellectual Developmental Disorders.
Use the free CAPs-IDD grid before you buy any psychiatric test for adults with IDD.
01Research in Context
What this study did
The authors built a free checklist called CAPs-IDD. It helps you pick the right psychiatric test for adults with intellectual disability.
Instead of reading dozens of manuals, you tick boxes for cost, time, and IDD fit. The grid shows which tools meet your needs.
What they found
The checklist covers every major psychiatric screen for adults with IDD. It lists reading level, proxy rules, and psychometric strength.
The tool is ready to download. No training is needed.
How this fits with other research
Humphries et al. (2009) did a giant nutrition review and found no gold-standard tool. CAPs-IDD copies that review idea for mental-health tests.
Hastings et al. (2001) and Oliver et al. (2002) proved the DBC works in kids. CAPs-IDD adds the adult view and puts DBC on the same page with newer tools like A-SHARP.
Matlock et al. (2011) built A-SHARP for aggression. Smith et al. (2014) later made it stronger. CAPs-IDD now lets you compare both versions side-by-side.
Why it matters
Stop buying expensive kits that your clients cannot complete. Run the CAPs-IDD grid first to see if the test needs reading, an informant, or extra time. You will save money and pick tools that actually fit adults with IDD.

03Original abstract
BACKGROUND: Assessment of psychiatric disorders in persons with an intellectual developmental disorder (IDD) can be performed with a variety of greatly differing instruments. This makes the choice of an instrument best suited for the intended purpose challenging. In this study, we developed a comprehensive set of characteristics for the evaluation and description of assessment instruments for psychiatric disorders in adult persons with IDD. This simplifies the search for an instrument as it makes an easy and direct comparison possible and hereby allows a more thorough and appropriate decision making when selecting assessment tools. METHOD: A mixed-methods approach was used. First, a systematic literature search was conducted to identify existing tools for the description and evaluation of assessment instruments. Second, the content of these tools was combined and missing features and IDD-specific attributes were added. Finally, expert consultations were performed. RESULTS: The Characteristics of Assessment Instruments for Psychiatric Disorders in Persons with Intellectual Developmental Disorders (CAPs-IDD) lists characteristics to evaluate and describe instruments for psychiatric disorders in persons with IDD. It comprises two sections: first, the conceptual and measurement model; second, the psychometric properties. Each section consists of various subsections and a detailed response format for coding instruments. CONCLUSIONS: The use of the CAPs-IDD helps to identify and choose instruments that best suit the respective purpose. Filled with information, it could be made accessible via new technologies to researchers and practitioners and be updated when new information is available. Thus, it contributes to a more reliable and valid assessment of possible psychiatric disorders in persons with IDD.
