Zusammenfassung: | 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:
α
=
.61) to excellent (Stereotyped Behavior,
α
=
.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. |
