Persistence of early emerging aberrant behavior in children with developmental disabilities

This study examined the persistence of early emerging aberrant behavior in 13 preschool children with developmental disabilities. The severity of aberrant behavior was assessed every 6 months over a 3-year period. Teachers completed the assessments using the Aberrant Behavior Checklist [Aman, M. G., & Singh, N. N. (1986). Aberrant Behavior Checklist: Manual. East Aurora, NY: Slosson Educational Publications; (1994). Aberrant Behavior Checklist - Community. East Aurora, NY: Slosson Educational Publications]. Problem behaviors were present in all children at the beginning of the study. Nine of the 13 children entered the study with relatively high levels of aberrant behaviors that showed little change over the 3 years. These data suggest that aberrant behaviors often emerge early and can be highly persistent during the preschool years. Prevention would, therefore, seem to require home-based interventions that begin before 4 years of age. © 2004 Elsevier Ltd. All rights reserved.
