Antisocial and delinquent behaviors in youths with mild or borderline disabilities

Six types of antisocial and delinquent behaviors (e.g., property destruction and authority avoidance) were assessed in 526 youths (11 to 24 years of age) with mild to borderline intellectual disabilities and 1,030 11- to 18-year-olds without intellectual disabilities. Overall, 10% to 20% of youths with intellectual disabilities exhibited some type of antisocial and delinquent behavior, which were quite persistent over a 5-year period. Youths who exhibited one type of antisocial and delinquent behavior were likely to also exhibit other types of such behaviors. Being male, younger, and having behavioral problems particularly predicted these behaviors across a 5-year period. Overall, boys but not girls with intellectual disabilities exhibited antisocial and delinquent behaviors more often than peers without intellectual disabilities. Clinical implications and implications for future research are discussed. © American Association on Intellectual and Developmental Disabilities.
