Accumulating research suggests that psychopathy can be disaggregated into low-anxious primary and high-anxious secondary variants, and this research may be important for understanding antisocial youths with callous-unemotional traits. Using model-based cluster analysis, the present study disaggregated 165 serious male adolescent offenders (M age = 16) with high scores on the Youth Psychopathic Traits Inventory into primary and secondary variants based on the presence of anxiety. The results indicated that the secondary, high-anxious variant was more likely to show a history of abuse and scored higher on measures of emotional and attentional problems. On a picture version of the dot-probe task, the low-anxious primary variant was not engaged by emotionally distressing pictures, whereas the high-anxious secondary variant was more attentive to such stimuli (Cohen d = 0.71). Although the two groups differed as hypothesized from one another, neither differed significantly in their emotional processing from a nonpsychopathic control group of offending youth (n = 208). These results are consistent with the possibility that the two variants of psychopathy, both of which were high on callous-unemotional traits, may have different etiological pathways, with the primary being more related to a deficit in the processing of distress cues in others and the secondary being more related to histories of abuse and emotional problems.

Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying-as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement-and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.

Research suggests that students who bully may perceive the school climate less favorably. Person-centered analyses were used to identify distinct groupings of bullying behaviors and related social-emotional factors (i.e., victimization, internalizing, and perception of school and bullying climate). Latent class analyses were conducted on a sample of 10,254 middle and 2509 high school students and indicated four classes in middle school (Low Involvement, Verbal, High Physical/High Verbal, and High Involvement) and three classes in high school (Low Involvement, Verbal, and High Involvement). A Low Involvement bullying class characterized most students and was related to positive adjustment, whereas a High Involvement bullying class represented the smallest proportion of the sample (1.6% middle school and 7.3% in high school). Students in the High Involvement class reported increased victimization and internalizing problems, feeling less safe and less belonging, and perceiving the school climate to be more supportive of bullying (i.e., perceiving adults' prevention and intervention efforts as ineffective). In middle school, the High Physical/High Verbal class reported significantly higher levels of victimization as compared to the Verbal class. Findings highlight heterogeneity in bullying behaviors and underscore the importance of prevention and intervention programming that addresses safety and belonging.

Although research indicates that female offenders demonstrate higher rates of mental health symptoms than male offenders, the lack of data on directly comparable groups of delinquent and community youths has limited this comparison. The current study includes adolescents detained in juvenile detention facilities (girls = 157; boys = 276) or who resided in the community (girls = 193; boys = 242) from four different geographical locales. Results indicate that the relative magnitude of gender differences was greater in detained youths than in community youths, with detained girls exhibiting greater levels of symptomatology than would be predicted on the basis of gender or setting alone. Although it may be self-evident that detained populations exhibit higher levels of externalizing problems than community populations, the present study helps to quantify such differences by using common measures and demographically matched samples and demonstrates that detained versus community differences are larger among girls than among boys.

Research on the role of race and urbanicity in bullying involvement has been limited. The present study examined bullying involvement subgroups that relate to race, urbanicity, and the perceived reason for the bullying. Self-report data were collected from 10,254 middle school youth (49.8 % female; 62.4 % Caucasian, 19.0 % African American, and 5.6 % Hispanic) and latent class analyses were used to identify three subtypes of bullying involvement: low involvement (50 %), victim (31.3 %), and bully-victim (18.7 %). Irrespective of urbanicity (urban vs. non-urban), African American youth were more likely to be members of either the victim or bully-victim classes than the low involvement class. Further exploration of the community context suggested that urbanicity was associated with the increased likelihood of having been racially bullied. Urban bully-victims were also more likely to have been bullied about money than non-urban bully-victims. Findings underscore the importance of addressing both race and urbanicity for culturally sensitive prevention programming.

The present study investigates how visitation from parents impacts youths' mental health in the first two months of incarceration in a secure juvenile facility. A diverse sample of 276 male, newly incarcerated serious adolescent offenders (14-17 years) was interviewed over a 60-day period. Results indicate that youth who receive visits from parents report more rapid declines in depressive symptoms over time compared to youth who do not receive parental visits. Moreover, these effects are cumulative, such that the greater number of visits from parents, the greater the decrease in depressive symptoms. Importantly, the protective effect of receiving parental visits during incarceration exists regardless of the quality of the parent-adolescent relationship. Policy changes that facilitate visitation may be key for easing adjustment during the initial period of incarceration.

Despite broad consensus that most juvenile crimes are committed with peers, many questions regarding developmental and individual differences in criminal style (i.e., co-offending vs. solo offending) remain unanswered. Using prospective 3-year longitudinal data from 937 14- to 17-year-old serious male offenders, the present study investigates whether youths tend to offend alone, in groups, or a combination of the two; whether these patterns change with age; and whether youths who engage in a particular style share distinguishing characteristics. Trajectory analyses examining criminal styles over age revealed that, while most youth evinced both types of offending, two distinct groups emerged: an increasingly solo offender trajectory (83%); and a mixed style offender trajectory (17%). Alternate analyses revealed (5.5%) exclusively solo offenders (i.e., only committed solo offenses over 3 years). There were no significant differences between groups in individuals’ reported number of friends, quality of friendships, or extraversion. However, the increasingly solo and exclusively solo offenders reported more psychosocial maturity, lower rates of anxiety, fewer psychopathic traits, less gang involvement and less self reported offending than mixed style offenders. Findings suggest that increasingly and exclusively solo offenders are not loners, as they are sometimes portrayed, and that exclusively solo offending during adolescence, while rare and previously misunderstood, may not be a risk factor in and of itself.

The presence of callous-unemotional (CU) traits designates a subgroup of antisocial youth at risk for severe, aggressive, and stable conduct problems. As a result, these traits should be considered as part of the criteria for conduct disorder. The present study tests 2 possible symptom sets (4- and 9-item criteria sets) of CU traits that could be used in diagnostic classification, assessed using self-report with a sample of 643 incarcerated adolescent (M age = 16.50, SD = 1.63 years) boys (n = 493) and girls (n = 150). Item response theory analysis was employed to examine the unique characteristics of each criterion comprising the 2 sets to determine their clinical utility. Results indicated that most items comprising the measure of CU traits demonstrated adequate psychometric properties. Whereas the 9-item criteria set provided more information and was internally consistent, the briefer 4-item set was equally effective at identifying youth at-risk for poor outcomes associated with the broader CU construct. Supporting the clinical utility of the criteria sets, incarcerated boys and girls who endorsed high levels of CU symptoms across criteria sets were particularly at-risk for proactive aggression and violent delinquency.
