The French PAS-ADD Checklist is a reliable screening tool for psychiatric disorders in adults with intellectual disabilities. While its sensitivity was lower than the English version, its specificity was higher, indicating acceptable validity.
Area of Science:
- Psychiatry
- Psychometrics
- Developmental Disabilities
Background:
- Psychiatric Assessment Schedule for Adult with Developmental Disability (PAS-ADD) Checklist developed as a screening tool for non-specialists.
- PAS-ADD Checklist validated for adults with intellectual disabilities (ID).
- Need for psychometric measures in ID population addressed by PAS-ADD.
Purpose of the Study:
- To translate and validate the French version of the PAS-ADD Checklist.
- To assess psychometric properties of the French PAS-ADD Checklist in outpatients with ID.
- To compare the French version with the original English version.
Main Methods:
- Translation and back-translation for French version creation.
- Assessment of acceptability, internal consistency, inter-rater reliability, and factorial analysis.
- Calculation of sensitivity and specificity for the French PAS-ADD Checklist.
Main Results:
- Good to acceptable internal consistency (Cronbach's alpha > 0.6).
- High inter-rater reliability (Spearman correlations > 0.66).
- Sensitivity 55%, Specificity 70%; confirmatory factor analysis showed mediocre fit.
Conclusions:
- French PAS-ADD Checklist demonstrates acceptable validity in the studied sample.
- Higher specificity but lower sensitivity compared to the English version.
- Reliable as a general screening tool for psychiatric disorders in French-speaking ID population.
