The Behavior Problems Inventory: an instrument for the assessment of self-injury, stereotyped behavior, and aggression/destruction in individuals with developmental disabilities

J Autism Dev Disord. 2001 Dec;31(6):577-88. doi: 10.1023/a:1013299028321.


The Behavior Problems Inventory (BPI-01) is a 52-item respondent-based behavior rating instrument for self-injurious, stereotypic, and aggressive/destructive behavior in mental retardation and other developmental disabilities. Items are rated on a frequency scale and a severity scale. The BPI-01 was administered by interviewing direct care staff of 432 randomly selected residents from a developmental center between the ages of 14 to 91 years. For 73% of those selected, at least one problem was endorsed on the BPI-01. A total of 43% showed self-injury, 54% stereotyped behavior, and 38% aggressive/destructive behavior. Confirmatory factor analysis and item-total correlations supported the three a priori factors. Analyses of variance (ANOVA) showed that of the variables age, sex, and level of mental retardation, only the latter had a significant effect on the BPI-01 total score, the SIB subscale score, and the Stereotyped Behavior subscale score. Aggression/destruction was not significantly related to any of the three variables. Individuals with a diagnosis of pervasive developmental disorder had higher scores on all three subscales than those without, whereas residents with a diagnosis of stereotyped movement disorder had higher Stereotyped Behavior scale scores than those without. The BPI-01 was found to be a reliable (retest reliability, internal consistency, and between-interviewer-agreement) and valid (factor and criterion validity) behavior rating instrument for problem behaviors in mental retardation and developmental disabilities with a variety of potentially useful applications. Strengths and limitations of the instrument are discussed.
