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.
