The Forensic Outpatient Risk Assessment and Evaluation (Fore)
This study evaluates the interrater reliability and predictive validity of a relatively new risk assessment tool designed for use in forensic outpatient populations, the Forensic Outpatient Risk Assessment and Evaluation (FORE). Data were collected from two samples: the first comprising 80 outpatients to assess interrater reliability between therapist–student and student–student rater pairs, and the second consisting of N = 1,268 patients for pre…
Effectiveness of Moral Developmental Interventions for Youth Engaged in Delinquent Behavior
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 ava…
Online Delinquent Behaviors of Adolescents
In this study we examined whether aspects of parental monitoring of adolescents’ online behavior (rules regarding time spent on the internet, rules regarding content of internet use, frequency of communication, and quality of communication about internet use) are related to different kinds of online delinquent behaviors (sexting, spreading viruses, DDoS attacking, hacking, and online threatening) and whether the level of adolescents’ problematic …
Safety First! Residential Group Climate and Antisocial Behavior
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 res…
Youth Interventions With and Without Supervised Practice
The development of adolescents in a non-residential alternative educational facility, including the prevention of secure residential placement
This study examined the development of 74 adolescents (13 to 17 years old, 62% boys) after their placement in the non-residential alternative educational facility School2Care, including the prevention of secure residential placement. Results showed that 70% of the adolescents were not placed in a secure residential facility up until six months after leaving the educational facility. Adaptive emotion regulation strategies and feelings of empowerme…
Children’s Rights in Secure Residential Youth Care in the Netherlands
This study examines the extent to which secure residential youth care in the Netherlands complies with children’s rights as laid down in the United Nations Convention on the Rights of the Child ( uncrc ) and the Dutch Youth Act. Residential group climate was measured with the Prison Group Climate Instrument ( pgci ), which assesses quality of group care from the perspective of the three basic needs for human self-determination: contact, autonomy …
Differences between boys and girls in perceived group climate in residential youth care
The aim of the present study was to examine differences in perceived living group climate between boys and girls in a sample of 344 youth (68.6% male, M age = 16, SD = 1.58) receiving residential youth care in the Netherlands. Participants filled out self-report measures on living group climate. Results of multilevel regression models indicated that girls in non-correctional facilities experienced living group climate most positively, and girls i…
Youth Initiated Mentoring
Differences between adolescents who do and do not successfully complete their program within a non-residential alternative education facility
In this retrospective longitudinal study we examined which characteristics of 114 Dutch adolescents, aged 12–18 years, and their environment, predicted (un)successful completion of a non-residential alternative educational program for adolescents with complex problems, who are at risk for school drop-out or residential placement. The adolescents received care and education in a non-residential alternative educational facility (School2Care) for a …
Non-Specific versus Targeted Approaches to Youth Mentoring
Foster care placement instability
The impact of classroom climate on students' perception of social exclusion in secondary special education
Group climate and treatment motivation in secure residential and forensic youth care from the perspective of self determination theory
Sports Participation and Juvenile Delinquency
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 th…
Can community-based interventions prevent child maltreatment
Despite the many efforts taken to prevent child maltreatment, this continues to be a significant worldwide problem. Interventions predominantly focus on ‘at risk’ populations and individual characteristics of the victim or abuser, but is that enough? The present review was designed to examine the potential of community-based programmes, those that target the problem solving and helping processes in the community, and thereby aim to prevent child …
Children in Residential Care
Purpose: This study describes the development and validation of the Group Climate Instrument for Children aged 8 to 15 years (GCIC 8-15), which purports to measure the quality of group climate in residential care. Methods: A confirmatory factor analysis was performed on data of 117 children in Dutch residential youth care. Reliability analysis was performed and concurrent validity was tested. Results: An adequate fit of a two-factor model indicat…
