Non-medical use of prescription drugs (NMUPD) by adolescents is a significant public health concern. The present study investigated the profile of NMUPD in 1349 adolescent offenders from the Pathways to Desistance project, and whether NMUPD predicted future delinquency using longitudinal data. Results indicated that increased frequency and recency of NMUPD in adolescent offenders are related to some demographic factors, as well as increased risk for violence exposure, mental health diagnoses, other drug use, and previous delinquency, suggesting that severity of NMUPD is important to consider. However, ANCOVA analyses found that NMUPD was not a significant predictor of drug-related, non-aggressive, or aggressive delinquency 12 months later beyond other known correlates of delinquency. Age, sex, exposure to violence, lower socioeconomic status, more alcohol use, and having delinquency histories were more important than NMUPD in predicting future delinquency. These findings suggest that although NMUPD is an important risk factor relating to many correlates of delinquency, it does not predict future delinquency beyond other known risk factors.

Revenge goals are correlated with maladjustment, and retaliation is a factor driving youth violence. However, revenge might be an important social tool adolescents use to achieve (self-)justice in environments where institutionalized interventions from authorities such as teachers or police are limited. This qualitative secondary analysis of 50 revenge scenarios from a larger study (N = 358 youth-caregiver dyads) expands one-dimensional knowledge from closed-answer vignettes to the rich real-world experiences of youth (aged 10-16; 30 boys, 20 girls), from an urban community sample. Ten patterns of qualitative differences in cognition and emotion of revenge scenarios emerged and are discussed within the revised model of social information processing (SIP). Importance of reputation, confidence in non-violent solutions, and the influence of intense emotions were among the themes. Gender differences and implications for prevention are discussed.

Prior research indicates an association between exposure to trauma (e.g., being victimized) and perpetration of crime, especially in the context of chronic victimization. This study examines the relationship between trauma exposure, posttraumatic stress disorder (PTSD), and history of arrest and incarceration among a representative sample of black Americans from the National Survey of American Life (N = 5,189). One-third had a history of arrest, and 18 percent had a history of incarceration. Frequency of trauma exposure was associated with involvement with the criminal justice system. Relative to never experiencing trauma, experiencing ≥4 traumas was associated with elevated odds of arrest (odds ratio [OR] = 4.03), being jailed (OR = 5.15), and being imprisoned (OR = 4.41), all p < .01. PTSD was also associated with likelihood of incarceration among those with a history of trauma (OR = 2.18, p < .01). Both trauma exposure and trauma-associated psychopathology are associated with increased likelihood of arrest and incarceration in adulthood among black Americans.

Associations between community violence exposure, family management practices, and substance use were compared in a sample of early adolescents in low-income communities from the United States (N = 151; M age = 12.71 years, standard deviation = 0.65; 50.3% female) and South Africa (N = 175; M age = 12.55 years, standard deviation = 0.85; 64.6% female) using home interviews with youth and their maternal caregivers. Past year victimization was associated with recent youth substance use. The moderating role of family management practices varied by type of practice (e.g., parental knowledge, control, solicitation, or child disclosure), reporter, and country. High parental knowledge reported by caregiver was protective against substance use only for South African youth. In youth reports, parental knowledge was protective across the United States and South Africa. Youth reports of their disclosure to parents were negatively associated with substance use in the United States but not South Africa. These data highlight the importance of considering both ecological context and reporter in the links between violence exposure, parenting, and substance use in youth.
