Abstract:

Incarcerated populations have an estimated incidence of intellectual disabilities (IDs) far higher than national norms, ranging as high as 10%. In the present study, the relation between ID and violence exposure in 115 incarcerated adolescents was examined. Interpersonal violence exposure (IPV-E) predicted an average decrease in full scale IQ of 4.5 points, explaining approximately 5% of the difference in IQ. Child maltreatment increased the odds of having a verbal disability by three folds and explained 17% of the variance in verbal disability. Hierarchical regression was used to examine the relative contribution of ethnicity, poverty, and violence exposure to intellectual functioning. The literature on racial bias in incarceration and the implications for the present study are discussed.
