A Dutch version of the Psychopathology Inventory for Mentally Retarded Adults (PIMRA)

Eighty-nine mildly mentally retarded adults were assessed using the Psychopathology Inventory for Mentally Retarded Adults (PIMRA). This study reports on the psychometric properties of the PIMRA in a Dutch population, the correlation between self-report and ratings-by-others forms, and the relationship of the PIMRA to both behavior problems and subject characteristics. It was revealed that internal consistency was good for both forms on total scores but modest for most of the subscales. Furthermore, interrater reliability was low to modest. Both forms of the PIMRA showed good criterion validity. The correlation between the two forms was modest. A strong relationship was found between PIMRA scores and behavior problems, as measured using the Reiss Screen of Maladaptive Behavior. Furthermore, the relationship between PIMRA scores and subject characteristics was weak.
