Forecasting recidivism in delinquency by intelligence and related constructs

The Role of Dynamic Risk and Protective Factors in Predicting Violent Recidivism: Intellectual Ability as a Possible Moderator?

This study investigated which risk and protective factors, based on the 14 clinical indicators of the Historical-Clinical-Future Revised, significantly predicted violent recidivism in a sample of 315 male forensic psychiatric patients. Additionally, it was investigated whether these associations were moderated by intellectual ability. Regarding risk factors, a stronger influence of risky network members, and higher levels of hostility, impulsivity, and addiction significantly predicted violent recidivism. Likewise, regarding protective factors, poorer social and labor skills, and a lower degree of patient's acceptance of crime responsibility were significant predictors of violent recidivism. Contrary to our expectations, better coping skills and more insight into risky behaviors that can lead to relapse also contributed significantly to an increased likelihood of violent recidivism. Intellectual ability had no significant moderating effect on the associations between the factors and violent recidivism. The results offer an insight into which factors need to be prioritized during treatment.

Intelligent diagnosing of intellectual disabilities in offenders: food for thought

Research on offenders with intellectual disabilities (IDs) in the criminal justice arena is on the rise, reflected by a growing number of relevant publications each year. However, there is a long recognized methodological problem that hampers the comparability of empirical studies and that raises doubts about the accuracy of prevalence rates, comorbidities, and various correlates and characteristics. In this paper we will argue that the crux of the problem can, on the one hand, be found in the plurality of assessment methods for intelligence and adaptive functioning, which are not all sufficiently reliable and valid. On the other hand, assessment of IQ in criminal justice and mental health-related areas appears to be informed more by practical aspects and needs rather than grounded in a solid theoretical model. Hence, we suggest that the Cattell-Horn-Carroll (CHC) model of intelligence has potential value in this regard, and deserves a closer look. Finally, we will discuss its incorporation into, and possible implications for, criminal justice practice and future study designs.

Recognition of facial affect in girls with conduct disorder

Impaired recognition of facial affect has been reported in youths and adults with antisocial behavior. However, few of these studies have examined subjects with the psychiatric disorders associated with antisocial behavior, and there are virtually no data on females. Our goal was to determine if facial affect recognition was impaired in adolescent girls with conduct disorder (CD). Performance on the Ekman Pictures of Facial Affect (POFA) task was compared in 35 girls with CD (mean age of 17.9 years+/-0.95; 38.9% African-American) and 30 girls who had no lifetime history of psychiatric disorder (mean age of 17.6 years+/-0.77; 30% African-American). Forty-five slides representing the six emotions in the POFA were presented one at a time; stimulus duration was 5s. Multivariate analyses indicated that CD vs. control status was not significantly associated with the total number of correct answers nor the number of correct answers for any specific emotion. Effect sizes were all considered small. Within-CD analyses did not demonstrate a significant effect for aggressive antisocial behavior on facial affect recognition. Our findings suggest that girls with CD are not impaired in facial affect recognition. However, we did find that girls with a history of trauma/neglect made a greater number of errors in recognizing fearful faces. Explanations for these findings are discussed and implications for future research presented.
