title: Convergent validity of the aberrant behavior checklist and behavior problems inventory with people with complex needs.
abstract: The current study aimed to replicate and extend Rojahn et al. [Rojahn, J., Aman, M. G., Matson, J. L., & Mayville, E. (2003). The aberrant behavior checklist and the behavior problems inventory: Convergent and divergent validity. Research in Developmental Disabilities, 24, 391-404] by examining the convergent validity of the behavior problems inventory (BPI) and the aberrant behavior checklist (ABC) for individuals presenting with multiple complex behavior problems. Data were collected from 69 children and adults with severe intellectual disabilities and challenging behavior living in residential establishments. MANCOVA analyses showed that individuals with elevated BPI stereotyped behavior subscale scores had higher scores on ABC lethargy and stereotypy subscales, while those with elevated BPI aggressive/destructive behavior subscale scores obtained higher scores on ABC irritability, stereotypy and hyperactivity subscales. Multiple regression analyses showed a corresponding pattern of results in the prediction of ABC subscale scores by BPI subscale scores. Exploratory factor analysis of the BPI data suggested a six-factor solution with an aggressive/destructive behavior factor, four factors relating to stereotypy, and one related to stereotypy and self-injury. These results, discussed with reference to Rojahn et al. [Rojahn, J., Aman, M. G., Matson, J. L., & Mayville, E. (2003). The aberrant behavior checklist and the behavior problems inventory: Convergent and divergent validity. Research in Developmental Disabilities, 24, 391-404], support the existence of relationships between specific subscales of the two instruments in addition to an overall association between total scores related to general severity of behavioral disturbance.
