The Behavior Problems Inventory (BPI-01) in community-based adults with intellectual disabilities: reliability and concurrent validity vis-à-vis the Inventory for Client and Agency Planning (ICAP).
BPI-01 remains reliable and valid for tracking severe behavior problems in community adults with ID.
01Research in Context
What this study did
The team gave the Behavior Problems Inventory (BPI-01) to caregivers of adults with intellectual disability living in group homes and day programs.
They also gave the same adults the Inventory for Client and Agency Planning (ICAP).
Two raters scored each BPI-01 twice, two weeks apart, to check reliability.
What they found
The BPI-01 showed strong agreement between raters and across the two weeks.
Its scores lined up well with the ICAP behavior sub-scale, showing it measures what it claims.
In short, the tool is solid for tracking self-injury, stereotypy, and aggression in community adults.
How this fits with other research
Weiss et al. (2001) built the original BPI-01 in residential facilities; this 2010 study proves the same tool works just as well in everyday community settings.
Lundqvist (2011) repeated the check in Swedish group homes and got the same clean three-factor structure, giving cross-country confidence.
Rojahn et al. (2012) later trimmed the 49-item form to a 30-item short form and found equal reliability, so you can now save time without losing quality.
Why it matters
If you assess adults with ID in day or residential programs, you can trust the BPI-01 to give stable, valid scores. Use the full form when funding requires detail, or grab the 30-item BPI-S when you need a quick screen before treatment planning. Either way, you will have numbers you can bank on.

03Original abstract
Reliability and concurrent validity of the Behavior Problems Inventory (BPI-01; Rojahn et al., 2001) was examined in a sample of 130 community residing adults with mild to profound intellectual disabilities with high rates of behavior problems and concurrent mental health problems. The BPI-01 and the Inventory for Client and Agency Planning (ICAP; Bruininks et al., 1986) were administered twice within a mean time interval of 7.8 weeks by 20 trained and experienced staff members. All three BPI-01 subscales had high inter-rater agreement (Self-Injurious Behavior [SIB]: mean ICC=.84; Stereotyped Behavior: mean ICC=.75; Aggressive/Destructive Behavior: mean ICC=.82), and stable test-retest reliability (SIB, mean ICC=.91; mean Stereotyped Behavior, mean ICC=.89, and Aggressive/Destructive Behavior, mean ICC=.88); internal consistency ranged from poor (SIB: alpha=.61) to excellent (Stereotyped Behavior, alpha=.90). Using the ICAP as criterion measure, the BPI-01 showed robust convergent validity. Solid relationships between BPI-01 subscales and corresponding ICAP subscales corroborated the concurrent validity of the BPI-01.
