Refugee children and adolescents have often experienced negative or traumatic events, which are associated with stress and mental health problems. A specific music therapy intervention is developed for this group in school settings. The aim of the present study was to set the first steps in the implementation of this intervention. A process evaluation was performed using a mixed method design among refugee children and adolescents (6–17 years) at three different schools in the Netherlands. Interviews were conducted with teachers and music therapists before, at the midpoint, and after the intervention. At these moments, children completed a classroom climate questionnaire and a visual analogue scale on affect. The results indicate that the intervention strengthens the process of social connectedness, resulting in a “sense of belonging”. The intervention may stimulate inclusiveness and cultural sensitivity, and may contribute to a safe environment and the ability of teachers to adapt to the specific needs of refugee children. Refugee children and adolescents showed a decrease of negative affect during the intervention. When implementing the intervention in schools, it is important to take into account the initial situation, the prerequisites for the intervention, the professional competence, the experience of music therapists, and the collaboration and communication between the professionals involved.

There is vast empirical evidence showing that juvenile delinquency is associated with delays in moral development, including moral judgment, empathy, and self-conscious emotions (guilt and shame). Consequently, interventions have been developed that target moral development of juvenile delinquents to reduce criminal offense recidivism. However, a comprehensive synthesis of studies examining the effectiveness of these interventions was not yet available. The present meta-analysis of (quasi-)experimental research therefore examined the effects of interventions that target moral development of youth engaged in delinquent behavior. Interventions that targeted moral judgment (11 studies and 17 effect sizes) showed a significant and small-to-medium effect on moral judgment ( d = 0.39), with intervention type as a significant moderator, but no significant effect on recidivism ( d = 0.03; 11 studies and 40 effect sizes). No (quasi-)experimental studies were found that targeted guilt and shame in juvenile offenders, and an insufficient number of studies (i.e., only two) were found to conduct a meta-analysis of interventions that target empathy. The discussion focuses on potential ways to improve moral development interventions for youth engaged in delinquent behavior, and provides suggestions for future research.

Youth are at elevated risk of becoming victims of sexual exploitation, which has a detrimental impact on their physical and psychological well-being. Understanding factors associated with sexual exploitation is key for prevention efforts and adequate and timely treatment. This systematic review sheds more light on this by providing an overview of both risk and protective factors for sexual exploitation in male and female youth from a cross-cultural perspective. In all, 65 studies were selected meeting the inclusion criteria: qualitative or quantitative peer-reviewed studies in English, Dutch, or German with findings on risk and protective factors associated with sexual exploitation in youth aged up to 24 years. Results show that there are common risk factors in male and female youth worldwide (e.g., adverse childhood experiences, lack of a social network, substance use, and running away). Positive and supportive relationships are an important protective factor in mitigating the risk of sexual exploitation. Geographic differences were found. In non-Western continents, more environmental factors (e.g., economic vulnerabilities, residential instability) were cited. Research in countries outside the United States is limited and protective factors and males are underexamined. To fully understand vulnerabilities in youth, their interactions, and possible gender differences and to address the needs of diverse populations, more insight should be gained into the broader range of risk and protective factors worldwide. This systematic review has made a valuable contribution to this by providing practice, policy, and research guidance in the establishment of more targeted prevention efforts, adequate treatment, and areas to address in future research.

This meta-analysis evaluated judicial interventions for juvenile delinquency certified by the Netherlands Youth Institute with “initial indications” for effectiveness. Ten (quasi-)experimental studies examining TOOLS4U, Multidimensional Family Therapy (MDFT), Multi Systemic Therapy (MST), Only You Decide who you Are (OYD), Responsive Social Skills Therapy (Re-SST), and Responsive Aggression Regulation Therapy (Re-ART) were synthesized. The overall effect was small, positive, and significant ( g = 0.22; 95%CI: 0.02, 0.42). Responsive cognitive behavioral therapy (Re-SST and Re-ART) and the sports-based intervention OYD seem effective, whereas social skills training (TOOLS4U) and family-based systemic interventions (MDFT and MST) seem ineffective. However, effectiveness of family-based programs can possibly be enhanced if youth at medium-to-high risk for delinquency is treated for 6 months or longer, which aligns with the Risk-Need-Responsivity model. Better program delivery and general instead of specific offenses were associated with larger effects. We advocate a stronger evidence-based RNR approach to juvenile delinquency in the Netherlands.

A systematic review and multilevel meta-analysis was performed (28 studies and 313 effect sizes) on the relation between residential group climate (i.e., safety, atmosphere, repression, support, growth, structure) and antisocial behavior, including aggression and criminal recidivism. A systematic search was conducted in PsychINFO, ERIC, and OVID Medline up to February 2023. Results showed a small but significant association ( r = .20) between residential group climate and antisocial behavior, equivalent to a 23% reduction of antisocial behavior in all clients receiving care in a residential facility with a therapeutic group climate. Moderator analyses showed that experienced safety was more strongly related to antisocial behavior ( r = .30) than the other dimensions of group climate (.17 < r < .20), while the effect size was somewhat larger for adults ( r = .24) than for youth ( r = .15). We conclude that residential facilities should consider safety as a priority and should involve clients in a positive process of change through the development of a therapeutic environment and delivery of evidence-based treatment, addressing their needs from the perspective of rehabilitation.
