Academic Motivation of Incarcerated Juveniles From the Perspective of Self-Determination Theory
This qualitative (multiple case) study investigated incarcerated juveniles’ experiences of being enrolled in an educational institution outside the correctional facility, and how this impacted their motivation, well-being, life satisfaction, and future social integration. Self-determination theory was used to understand how youth experienced fulfillment of their psychological needs (i.e., autonomy, competence, and relatedness). Results showed tha…
The effectiveness of interventions for youth that activate the social network
This meta-analysis aimed to examine the effectiveness of interventions for youth that activate the social network for improving youth outcomes (e.g. psychological problems, child safety). A literature search yielded 37 studies with 35 independent samples (N = 712,269) of youth aged 0-26 years (M = 7.20), and 409 effect sizes. A three-level meta-analysis controlling for the dependency among effect sizes within studies showed no overall effect of i…
The prevalence of placement breakdown in foster care
Group Climate in Residential Youth Care
Group climate in residential youth care is considered to be essential for treatment of youth and young adults. Various instruments exist to measure quality of living group climate, but some are lengthy, use complicated wording, which make them difficult to fill out by youth and individuals with a mild intellectual disability. The present study describes the development and rationale for the Group Climate Instrument—Revised (GCI-R). Construct vali…
It takes a safe village to raise a child—a commentary on Dana McCoy et al. (2023)
This commentary on the study by McCoy et al. (2023) examining the negative effects of neighborhood violence on the development of toddlers growing up in the city of São Paulo (Brazil) interprets these outcomes from the perspective of ecological system theory, modern brain research, and the prospect of resilience. We argue that societies should give children the opportunity to grow up in a safe and sufficiently affluent social environment in order…

Netherlands Trial Register NL7565. Retrospectively registered on 05/03/2019
Measuring sexual interaction competence in adolescents
This study aimed to investigate the internal structure, measurement invariance, and reliability of the Sexual Interaction and Relationship Questionnaire (SIRQ), which is a self-report instrument for measuring sexual interaction competence in adolescents. The SIRQ was administered in a clinical sample (N = 827; M=15.51 years, SD=1.98 years). The factor structure of the SIRQ was examined by performing a Principal Component Analysis (PCA) and a Conf…
Research Review
BACKGROUND: Parents' and peers' cannabis use are well-documented predictors of youth cannabis use, however, relatively little is known about the influence of siblings' cannabis use. Hence, this meta-analysis investigated the association between sibling-youth cannabis use (disorder) and explored moderation by sibling type (monozygotic- vs. dizygotic- vs. non-twins), age, age spacing, birth order, gender, and gender constellations (same- vs. mix- g…
Needs of Youth and Parents From Multi-Problem Families in the Search for Youth-Initiated Mentors
Youth-initiated mentoring is an innovative youth care approach in which youth recruit supportive adults from their social networks as a mentor for youth and a partner for parents and professionals. This qualitative interview study documents what youth ( n = 15) and parents ( n = 13) from multi-problem families look for in a mentor, what mentors ( n = 8) believe they have to offer, and whether what mentors believe to offer matches youth's and pare…
Mind-mindedness in out-of-home Care for Children
Most out-of-home placed children have experienced early adversities, including maltreatment and neglect. A challenge for caregivers is to adequately interpret their foster child’s internal mental states and behavior. We examined caregivers’ mind-mindedness in out-of-home care, and the association among caregivers’ mind-mindedness (and its positive, neutral, and negative valence), recognition of the child’s trauma symptoms, and behavior problems. …
A Meta-Analysis of the Effectiveness of EMDR and TF-CBT in Reducing Trauma Symptoms and Externalizing Behavior Problems in Adolescents
This multi-level meta-analysis tested if evidence-based trauma treatment was effective in reducing trauma symptoms and externalizing behavior problems in adolescents. Based on eight independent samples and 75 effect sizes, results indicated that Trauma Focused-Cognitive Behavioral Therapy (TF-CBT) and Eye Movement Desensitization Reprocessing (EMDR) had a large and significant overall effect ( d = 0.909) on reducing trauma symptoms and externaliz…
Measuring Aggression in German Youth Prison—A Validation of the German Reactive-Proactive Aggression Questionnaire (RPQ) in a Sample of Incarcerated Juvenile Offenders
The aim of the present study was to examine construct validity and reliability of the German reactive proactive aggression questionnaire (RPQ) in a sample of delinquent boys ( N = 156). A confirmatory factor analysis with a two-factor model of reactive and proactive aggression showed a good fit to the data. The factor structure of the original RPQ could be fully replicated in the German translation, and Cronbach’s alphas were good for both subsca…
Protective factors as uni- or bipolar factors and their incremental validity and accuracy in predicting general recidivism
Early assessment of the risk of child welfare involvement for preventive purposes
To prevent child welfare involvement by timely referring families to preventive interventions, it is essential to assess the risk of child welfare involvement in the general population as early as possible. To examine whether child welfare involvement can be predicted by demographic, socioeconomic, and criminal history factors. Data of 131,532 children and their parents were retrieved from Statistics Netherlands. Child welfare involvement compris…
Cross‐age peer mentoring for youth
Although most mentoring programs for youth are structured around intergenerational relationships, a growing number of programs rely on cross‐age peer mentoring. Such programs capitalize on the availability of youth mentors to promote positive outcomes in younger peers. This study used a multilevel meta‐analytic approach to estimate the effect size of cross‐age peer mentoring programs and evaluate potential moderators of peer mentoring program eff…
What makes Dutch youth comply with preventive Covid‐19 measures? An explorative study
The measures to contain the spread of COVID‐19 are challenging for youth, especially the social isolation measures. These measures are antagonistic to healthy youth development, which requires sufficient social contact with peers and adults. This explorative study examined what factors are associated with adherence to COVID‐19 measures in a sample of Dutch youth ( N = 263; 79.8% female) with ages ranging between 16 and 24 years ( M = 21.1 years; …
Youth Initiated Mentoring in Social Work
Effects of Awareness Programs on Juvenile Delinquency
Juvenile awareness programs, such as Scared Straight, remain in use despite the finding that these programs provoke rather than prevent delinquency. The aim of this study was to examine what program components are associated with program effectiveness, which is important for improving these programs. A three-level meta-analysis was conducted. A literature search yielded 13 independent studies ( N = 1,536) from which 88 effect sizes could be extra…
Personalizing Child Protection
Personalization is an important strategy for enhancing the effectiveness of treatment that is aimed at reducing the risk of child maltreatment. In recent years, a growing body of research has appeared on how child protection can benefit from the principles of the Risk-Need-Responsivity model, but no attention has yet been paid to the implementation of the responsivity principle in child protection. Put simply, this principle states that treatment…
Therapists’ Contributions to the Alliance in Home-Based Family Treatment
Alliance is a robust contributor to the outcome of adult, youth, and family therapy, but little is known about therapists’ contributions to the alliance in conjoint family treatment. We investigated the predictive value of therapists’ personality, clinical experience and observed alliance building behaviors for mid-treatment alliance as reported by therapists and family members. Participants were 77 parents and 21 youth from 57 families receiving…
Development and validation of the Attachment Relationship Inventory—Caregiver Perception 2–5 years (ARI‐CP 2–5)
There is a lack of instruments assessing child–caregiver attachment relationships in early childhood to be used in attachment‐based practice, in particular from a caregiver's perception, which is an important factor of clinical importance to take into account in parenting interventions targeting young children. Therefore, the 48‐item Attachment Relationship Inventory—Caregiver Perception 2–5 years (ARI‐CP 2–5) was developed. Survey data of 446 ca…
The Relation Between Attachment and Depression in Children and Adolescents
Insecure attachment to primary caregivers is associated with the development of depression symptoms in children and youth. This association has been shown by individual studies testing the relation between attachment and depression and by meta-analyses focusing on broad internalizing problems instead of depression or adult samples only. We therefore meta-analytically examined the associations between attachment security and depression in children…
Safety assessment in child welfare
This review aimed to compare child safety assessment instruments, which are used by child welfare professionals to determine whether a child is in immediate danger, and subsequently, whether immediate action is required to stop or prevent serious harm to the child. We searched electronic databases for articles discussing child safety assessment in the broadest possible sense, after which child safety assessment instruments were identified by sear…
Are We Barking Up the Right Tree? A Meta-Analysis on the Effectiveness of Prison-Based Dog Programs
Prison-based Dog Programs (PBDPs) are used in correctional facilities to decrease recidivism and improve social-emotional functioning. The aim of this meta-analysis was to provide an overview of the effectiveness of PBDPs, accounting for the potential influence of study, program, and sample characteristics through moderator analyses. We included 11 manuscripts, seven published and four unpublished, yielding 93 effect sizes ( N = 3,013). Eight stu…

A total of 145 effect sizes for different types of behavioral problems were derived from 24 controlled studies (n = 16,943 participants). A three-level random-effects meta-analysis was conducted. We found a small statistically sig…
The Effects of Youth Mentoring Programs
Does Natural Mentoring Matter? A Multilevel Meta‐analysis on the Association Between Natural Mentoring and Youth Outcomes
In this meta‐analytic review, we examined the relation between natural mentoring and youth outcomes in four domains: academic and vocational functioning, social‐emotional development, physical health, and psychosocial problems. Natural mentoring relationships are thought to foster positive youth development and buffer against the risks associated with the tumultuous years of adolescence. Two separate meta‐analyses were conducted on the presence o…

What works’ for juvenile prisoners
The Dutch juvenile justice system locks up an increasing number of adolescent boys and girls at a cost of approximately €250,000 for each inmate annually (Boone & Moerings, 2007; Tonry, 2005). Questions have been raised, however, about the cost‐effectiveness of treatment in closed institutions. This study, with a sample of 49 adolescents residing in a Dutch youth prison, examined the role of group climate in establishing and maintaining treatment…
Gender Differences in the Impact of Abuse and Neglect Victimization on Adolescent Offending Behavior
The present study examines gender differences in the association between abuse and neglect during childhood, and sexual and violent offending in juvenile delinquents. Female juvenile delinquents were more frequently victim of sexual and physical abuse and had a history of neglect and maltreatment than male juvenile offenders. Male juvenile offenders committed more sexual offenses and felony offenses against persons. Female juvenile offenders repo…
Ethnic identity, externalizing problem behaviour and the mediating role of self‐esteem among Dutch, Turkish‐Dutch and Moroccan‐Dutch adolescents
The present study examined whether self-esteem mediates the relationship between two aspects of ethnic identity (i.e. ethnic identity exploration and ethnic identity commitment-affirmation) and externalizing problem behaviour in Dutch, Turkish-Dutch and Moroccan-Dutch adolescents living in the Netherlands. A total number of 345 adolescents (115 Dutch, 115 Turkish-Dutch, 115 Moroccan-Dutch) with a mean age of 14.5 filled in questionnaires at schoo…
The Contribution of Organized Youth Sport to Antisocial and Prosocial Behavior in Adolescent Athletes
Repression in Residential Youth Care
Repression in residential youth care institutions can manifest itself openly in coercive measures or may be concealed in staff behavior that is endemic to residential youth care, such as soft power and strict behavioral control (i.e., structure), which threatens rehabilitative goals and might even violate children’s rights. To increase awareness of particularly the more hidden aspects of repression, this qualitative study follows the framework me…
Fear is the key
Purpose - This study seeks to examine the education, safety, and professional attitudes of group workers in a Dutch youth prison and to analyse their perceptions of the organisational culture and leadership by line management. To achieve therapeutic goals, group workers must maintain a balance between flexibility and control. Design/methodology/approach - A total of 59 group workers (40 per cent male and 60 per cent female) randomly chosen from e…

Predictors of Antisocial and Prosocial Behavior in an Adolescent Sports Context
This study examined antisocial and prosocial behavior of N = 439 adolescent athletes between 14 and 17 years of age (67 teams). Multi‐level analyses showed that team membership explained 20 and 13 percent of the variance in antisocial and prosocial behavior in the sports context, respectively. The team effects suggest that aggregating antisocial or prosocial adolescents within teams may partially explain differences in antisocial and prosocial be…

Relations Among Child Negative Emotionality, Parenting Stress, and Maternal Sensitive Responsiveness in Early Childhood
This short-term longitudinal study focuses on relations between preschool-aged childrens' perceived "difficult" temperament (defined as high negative emotionality) and observed maternal sensitive responsiveness in the context of maternal parenting stress. Design. Participants were fifty-nine 3-year-olds and their mothers. Mothers completed questionnaires for child temperament and parenting stress. Maternal sensitive responsiveness was observed du…
The association between childhood maltreatment, mental health problems, and aggression in justice‐involved boys
The link between childhood maltreatment and adolescent aggression is well documented; yet, studies examining potential mechanisms that explain this association are limited. In the present study, we tested the association between childhood maltreatment and adolescent aggression in boys in juvenile justice facilities (N = 767) and examined the contribution of mental health problems to this relationship. Data on childhood maltreatment, mental health…

An Exploration of Youth-Parent-Mentor Relationship Dynamics in a Youth-Initiated Mentoring Intervention to Prevent Out-of-Home Placement
This qualitative study explores the youth-initiated mentoring (YIM) approach for youth at risk for out-of-home placement. In this approach, a youth nominates someone from within their social network, and positions this person as a YIM to function as an ally for the youth and as a partner for parents and professional caregivers. Through interviews with six youth, six YIMs, and seven parents ( N = 19), we examined the positioning of a YIM and susta…

Child negative emotionality and parenting from infancy to preschool
This meta-analytic review (k = 62 studies; N = 7,613 mother-child dyads) shows that effect sizes for the association between child negative emotionality and parenting were generally small and were moderated by sample and measurement characteristics. The association between more child negative emotionality and less supportive parenting was relatively strong in lower socioeconomic status families, reversed in higher socioeconomic status families, a…
The Contribution of Organized Youth Sport to Antisocial and Prosocial Behavior in Adolescent Athletes
Research Review
Background: There is growing research interest in the association between parental control and child anxiety. Parental control may enhance child anxiety and parents may exert control in anticipation of their child’s anxiety‐related distress. Moreover, high levels of anxiety in parents could influence the development of parental control. Whereas past reviews have solely examined the relation between child anxiety and parental control, this meta‐an…

The Relation Between Insecure Attachment and Child Anxiety
Attachment theory suggests that children's attachment insecurity plays a key role in the development of anxiety. In the present study we evaluated the empirical evidence for the link between insecure attachment and anxiety from early childhood to adolescence. A meta-analysis of 46 studies, from 1984 to 2010, including 8,907 children, was conducted. The results show an overall effect size of r = .30, indicating that attachment is moderately relate…
