Background:
The Psychiatric Assessment Schedule for Adult with Developmental Disability (PAS-ADD) is an international reference tool for the diagnosis and assessment of mental health problems and behavioural disorders among people with intellectual disabilities. Although the original PAS-ADD instrument has been validated in the Spanish language, the shorter PAS-ADD Checklist has yet not been validated. The aim of this study is to validate the PAS-ADD Checklist for the Spanish population.
Methods:
The PAS-ADD Checklist Questionnaire was administered to 208 adults with intellectual disabilities at a vocational centre in Madrid, Spain. The psychometric analyses included internal consistency, inter-rater and test-retest reliability, Varimax rotation factor analysis for construct validity, criterion validity and feasibility.
Results:
The Cronbach's alpha was 0.80 for the overall questionnaire and between 0.40 and 0.79 for the subscales. The Kappa coefficients for test-retest and inter-rater reliability were between 0.66 and 0.80. Varimax rotation factor analysis showed five well-defined factors. The Kappa coefficients for criterion validity were between 0.30 and 0.70. Feasibility was also good.
Conclusions:
The PAS-ADD Checklist is a feasible and reliable instrument for carrying out initial assessment of the mental health status of adults with intellectual disabilities, referring cases to more specialised diagnosis and treatment.
