The effectiveness of prevention programs is often assessed by examining program effects of a variety of factors that are known to elevate or reduce risk for delinquent involvement. It is necessary to identify whether differential programming is required for significantly represented offender subpopulations, including those with emotional/behavioral disorders (E/BD) or learning disabilities (LD). This study sought to determine the relevance of specific individual, family, and school-risk factors for delinquency across three categorical subtypes ofjuvenile offenders: (a) those with E/BD, (b) those with LD, and (c) those offenders considered nondisabled.
