Factors contributing to criminal justice system involvement among individuals with developmental disabilities
This study examined the factors that may contribute to a person's with a developmental disability becoming involved in the criminal justice system by examining gender, ethnicity, level of mental retardation, prescription of psychotropic medication, and behavioral variables including an emotional, a social, and a communication domain. Participants included 180 forensically involved individuals and 189 individuals not involved forensically from two regional centers in California (N = 369). Two-hundred and thirty-one individuals were male and 138 were female. All participants were 18 years of age or older. Data were collected from the California Development Evaluation Report (CDER) database from each of the two regional centers. Logistic regression was used to determine significant factors in a developmentally disabled individual's involvement in the criminal justice system. The examined variables included gender, ethnicity, level of mental retardation, prescription of psychotropic medication, and behavioral variables. The analysis supported several of the hypotheses. The results appeared to follow the trend of the criminal justice system in general. The overall model was found to be statistically significant at an alpha level of .01 in predicting forensic involvement of individuals with a developmental disability, X2(11, N = 369) = 114.506, p < .001. Overall, the predictor variables accounted for between 26.7% and 35.6% of the variance in forensic involvement (Cox and Snell's R2 = .267, Nagelkerke's R2 = .356). In addition, successful prediction of forensic involvement was 75.6%, and correct classification for no forensic involvement was 72.0%, with an overall correct classification of 73.7%. This was significantly greater that the chance classification rate of 51.2%. The results of this study can be used to assist in determining at-risk individuals and in identifying clients who may benefit from prevention programs and education. They may also assist in treatment planning for care providers and case managers alike. Overall, it is the hope of the researcher that this study will assist with the goal of fewer individuals with developmental disabilities becoming criminally involved.
