Psychometric properties and factor structure of the Behavior Problems Inventory (BPI-01) in a Swedish community population of adults with intellectual disability.
The Swedish BPI-01 is a solid way to measure self-injury, stereotypy, and aggression in adults with ID, and the newer 30-item BPI-S works just as fast.
01Research in Context
What this study did
Lundqvist (2011) tested the Swedish BPI-01 on adults with intellectual disability living in the community. Caregivers answered 49 questions about self-injury, stereotypy, and aggression. The team checked if the three subscales held together and gave steady scores.
What they found
The three-factor structure held up. Internal consistency was acceptable for stereotyped behavior and for aggressive/destructive behavior. The study shows the Swedish BPI-01 is a sound tool for tracking problem behavior in adults with ID.
How this fits with other research
Van der Molen et al. (2010) found the same good reliability in US community adults, so the tool works on both sides of the Atlantic.
Dumont et al. (2014) later got the same positive results with Dutch adults in residential care, proving the BPI-01 travels across languages and settings.
Rojahn et al. (2012) then trimmed the form to 30 items. Their BPI-S keeps the same strength, so you can now save time without losing data.
Why it matters
If you assess adults with ID in community day programs, you can trust the Swedish BPI-01 or its 30-item BPI-S cousin. Both give quick, reliable scores for treatment planning and progress checks. Pick the short form when time is tight.

03Original 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.
