The DC-LD is a new classification system providing operationalized diagnostic criteria in recognition of lacking applicability of standard psychiatric criteria for adults with intellectual disability. This study attempts to evaluate internal consistency, inter-rater reliability and factor structure of the Psychopathology Checklists for Adults with Intellectual Disability (P-AID), a set of checklists developed from the DC-LD. The P-AID checklists comprising 10 psychiatric diagnoses and 8 types of problem behaviors were filled in by staff at community based homes for adults with intellectual disability in Western Norway. ⋯ Issues regarding sensitivity and specificity are discussed. This study is the first attempt to develop and evaluate Psychopathology Checklists based on the DC-LD. The results from this study indicate the P-AID can be used in identifying mental health needs at a detailed diagnostic level.
