Physical activity interventions are often implemented in the adolescent mental health care practice to prevent or treat psychosocial problems. To date, no systematic review of the effect of these physical activity interventions in adolescents has been conducted. In the current study, four multilevel meta-analyses were performed to assess the overall effect of physical activity interventions on externalizing problems, internalizing problems, self-concept, and academic achievement in adolescents. In addition, possible moderating factors were examined. In total, 57 studies reporting on 216 effect sizes were included, and the results showed significant small-to-moderate effects of physical activity interventions on externalizing problems (d=0.320), internalizing problems (d=0.316), self-concept (d=0.297), and academic achievement (d=0.367). Further, moderator analyses showed that outcome, study, sample, and intervention characteristics influenced the effects of physical activity interventions on psychosocial outcomes. Implications for theory and practice concerning the use of physical activity interventions in adolescent mental health care practice are discussed.

The current paper provides a narrative review of the literature on sexual abuse, involving children with Intellectual Disability (ID). The thirteen articles that were found and met our criteria vary in their definitions of sexual abuse and in how ID was determined. Still, they do paint a general picture concerning (1) the extent of sexual abuse, (2) the nature of the sexual abuse, and (3) the institutional reactions following sexual abuse of children with ID. Our findings confirm the greater vulnerability of children with ID to become involved in sexual abuse both as a victim and as a perpetrator, and we discuss ways to help strengthening prevention and intervention methods. Nevertheless, more research is needed, as it is still a rather unexplored topic, which is striking in light of the high vulnerability of this group.

Participation in sports activities is very popular among adolescents, and is frequently encouraged among youth. Many psychosocial health benefits in youth are attributed to sports participation, but to what extent this positive influence holds for juvenile delinquency is still not clear on both the theoretical and empirical level. There is much controversy on whether sports participation should be perceived as a protective or a risk factor for the development of juvenile delinquency. A multilevel meta-analysis of 51 published and unpublished studies, with 48 independent samples containing 431 effect sizes and N = 132,366 adolescents, was conducted to examine the relationship between sports participation and juvenile delinquency and possible moderating factors of this association. The results showed that there is no overall significant association between sports participation and juvenile delinquency, indicating that adolescent athletes are neither more nor less delinquent than non-athletes. Some study, sample and sports characteristics significantly moderated the relationship between sports participation and juvenile delinquency. However, this moderating influence was modest. Implications for theory and practice concerning the use of sports to prevent juvenile delinquency are discussed.

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n=231), physically abused (n=1,568), neglected (n=1,555), exposed to multiple forms of maltreatment (n=1,767), and non-victims (n=8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed.

Background Persons with an intellectual disability are at a higher risk of experiencing adversities. The concept of resilience offers promising insights into facilitating personal growth after adversity. The current study aims at providing an overview of the current research on resilience and the way this can contribute to quality of life in people with intellectual disability. Method A literature review was conducted in the databases PsycINFO and Web of Science. To evaluate the quality of the studies, the Mixed Method Appraisal Tool (MMAT) was used. Results The themes, autonomy, self‐acceptance and physical health, were identified as internal sources of resilience. External sources of resilience can be found within the social network and daily activities. Conclusion The current overview shows promising results to address resilience in adults with intellectual disability. More research is needed to identify the full range of resiliency factors.

Self-conscious emotions are expected to be related to delinquency, as they guide moral decision making. In the current study, two separate multilevel meta-analyses were performed to examine the overall relation between guilt, shame and delinquency. In addition, possible moderating factors were examined. In total, 25 studies with 24 independent samples, reporting on 75 effect sizes, were included. The results showed significant negative associations between guilt and delinquency (r = -.278), and between shame and delinquency (r = -.130),indicating that higher levels of guilt and shame were related to less delinquency. Implications for theory and practice concerning the role of self-conscious emotions in delinquency and offender treatment are discussed.
