Assessing callous–unemotional traits in adolescent offenders: Validation of the Inventory of Callous–Unemotional Traits

The presence of callous–unemotional (CU) traits designates an important subgroup of antisocial youth. To improve upon existing measures, the Inventory of Callous–Unemotional Traits (ICU) was developed to provide an efficient, reliable, and valid assessment of CU traits in samples of youth. The current study tests the factor structure and correlates of the ICU scale in a sample (n = 248) of juvenile offenders (188 boys, 60 girls) between the ages of 12 and 20 (M = 15.47, SD = 1.37). Confirmatory factor analyses are consistent with the presence of three independent factors (i.e., Uncaring, Callousness, and Unemotional) that relate to a higher-order callous–unemotional dimension. Also, CU traits overall showed associations with aggression, delinquency, and both psychophysiological and self-report indices of emotional reactivity. There were some important differences across the three facets of the ICU in their associations with these key external criteria.

Treatment-Related Reductions in Disability Are Associated with Reductions in Perceived Injustice Following Treatment of Whiplash Injury

Emerging evidence suggests that perceived injustice is a risk factor for poor recovery outcomes in individuals with whiplash injuries. The present study examined the relative contributions of treatment-related reductions in pain severity, depressive symptoms, and disability in the prediction of reductions in perceived injustice in individuals with whiplash injury. The study sample consisted of 71 individuals (43 women and 28 men) who sustained whiplash injuries in motor vehicle accidents and who were enrolled in a treatment program designed to promote functional recovery following whiplash injury. For the purposes of this study, only individuals who scored above the risk threshold on a measure of perceived injustice were included in the study sample. Participants completed measures of pain severity, disability, depressive symptomatology, and perceived injustice prior to treatment and after treatment. Change scores were computed for study variables. The results revealed that reductions in pain severity and disability were correlated with reductions in perceived injustice. Regression analyses revealed that only reductions in disability contributed significant unique variance to the prediction of reductions in perceived injustice. Clinical and theoretical implications of the present findings are discussed.     

Weekly community interviews with high-risk participants: operational issues

To address several key questions in social science research, repeated interviews of individuals drawn from difficult populations are required. This article describes an approach for addressing the challenges associated with longitudinal interview studies, including locating research participants, obtaining reliable and valid interview data over time, and retaining participants across the course of the study. We applied this approach to conduct a study designed to identify changeable risk factors for violence among high-risk people with mental illness. To successfully conduct weekly interviews of these individuals in the community across a 6-month period, we developed a flexible and personalized interview format; carefully selected, trained, and supervised staff; and developed incentives to maximize participant retention. Each of these three steps is discussed as a guide for future longitudinal studies that involve interviewing difficult populations.

Effect of Psychopathy, Abuse, and Ethnicity on Juvenile Probation Officers’ Decision-Making and Supervision Strategies

Probation officers exercise substantial discretion in their daily work with troubled and troubling juvenile offenders. In this experiment, we examine the effect of psychopathic features, child abuse, and ethnicity on 204 officers’ expectancies of, recommendations for, and approach to supervising, juvenile offenders. The results indicate that officers (a) have decision-making and supervision approaches that are affected by a youth’s psychopathic traits and history of child abuse—but not ethnicity; (b) view both abused youth and psychopathic youth as highly challenging cases on a path toward adult criminality; and (c) have greater hope and sympathy for abused youth than psychopathic youth. For abused youth, officers are likely to recommend psychological services and “go the extra mile” by providing greater support, referrals, and networking than is typical for their caseload. For psychopathic youth, officers expect poor treatment outcomes and are” extra strict,” enforcing rules that typically are not enforced for others on their caseload.     

Social Networks and Social Control of Probationers with Co-Occurring Mental and Substance Abuse Problems

Probationers with co-occurring mental and substance abuse problems (PCPs) are both subject to considerable social control, and at high risk of probation failure. In this study, we screened 601 probationers for symptoms, interviewed 82 identified PCPs about their relationships, and then followed these PCPs for eight months to record treatment nonadherence and other probation violations. First, PCPs’ social networks were small, heavily comprised of professionals and opposing forces who engaged in risky behavior, and saturated with pressure to adhere to treatment. Second, the size and composition of PCPs’ social networks were more relevant to rule compliance than social support and undermining. Third, the quality of PCPs’ relationships was key: satisfying relationships with clinicians and, to a lesser extent, officers and the core network related to low perceived coercion, high treatment adherence, and low risk of future violations. In particular, having a likable clinician who engaged in participatory decision-making reduced the risk of violations. Implications for contextually sensitive risk reduction efforts are discussed.
