Abstract

The aim of the present study was to evaluate the psychometric properties and factor structure of the Behavior Problems Inventory (BPI-01) in a community population. The Swedish version of the BPI-01 was administered by interviewing care staff of all adults (n=915) with administratively defined intellectual disabilities (IDs) living in Örebro County, Sweden. Sixty-two percent of the participants had at least one behavior problem. Altogether, 30.9% showed self-injurious behavior, 41.3% stereotyped behavior, and 34.8% aggressive/destructive behavior. All but the self-injurious behavior scale reached acceptable levels of internal consistency. Confirmatory factor analysis supported the unidimensionality of the subscales as well as the proposed three factor structure of the original BPI-01. The present study demonstrates that the three subscales are highly similar constructs across different language and cultural settings, and that the BPI-01 is applicable in research on populations with varying mental functioning, diagnoses, ages, and living arrangements.
