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).

Background: Children from multi-problem families have an increased risk for experiencing mental health problems. These families face problems in several domains that are often found to be chronic and intergenerational. Yet, the effects of mental health care for youths from multi-problem families are small at best, urging research on new treatment programs.

Unlabelled: A substantial number of children who experienced child maltreatment drop out of evidence-based trauma-focused treatments (TF-CBT). Identifying child, family, and treatment-related factors associated with treatment dropout is important to be able to prevent this from happening and to effectively treat children's trauma-related symptoms. Methods: A quantitative review was performed based on a systematic synthesis of the literature on potential risk factors for dropout of trauma-focused treatment in maltreated children.

Objective: The alliance in child and adolescent psychotherapy is widely recognized as an important factor in therapy. Studies on the alliance have increasingly focused on assessment of the alliance as a dyadic construct, measuring both client and therapist alliance ratings. However, cross-informant reports of the alliance in child psychotherapy have not yet been subjected to meta-analysis.

Parent-child interaction therapy (PCIT) is a short-term, evidence-based intervention for caregivers with children aged between 2 and 7 who exhibit behavioral problems. PCIT is effective, but has a high attrition rate ranging from 27% to 69%. We hypothesize that a low level of parental mind-mindedness-the parent's propensity to treat the child as an intentional agent with its own thoughts and emotions-might contribute to premature attrition or cause families to profit less from treatment.

Adverse childhood experiences (ACEs) are associated with an increased risk of developing severe emotional and behavioral problems; however, little research is published on ACEs for students with emotional and behavioral disorders (EBD) in special education (SE) schools. We therefore systematically explored the prevalence, type and timing of ACEs in these students from five urban SE schools in the Netherlands ( = 11.58 years; 85.

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 effectiveness.

This study examined whether protective factors are unique or the opposite of risk factors and whether they have incremental validity in the prediction of general recidivism. Using a sample of 3306 Dutch forensic outpatients, this study was the first large-sample study ever performed on this topic. Results from exploratory factor analyses demonstrated a relatively stable factor structure of 14 factors, consisting of 32 of the initially included 68 risk factors and 11 of the initially included 17 protective items.

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.

School-based programs seem promising for child abuse prevention. However, research mainly focused on sexual child abuse and knowledge is lacking on how individual program components contribute to the effectiveness of school-based prevention programs for any form of child abuse. This study aimed to examine the overall effect of these school-based programs on (a) children's child abuse-related knowledge and (b) self-protection skills by conducting two three-level meta-analyses.

Background: Although many child maltreatment risk assessment instruments have been implemented in child welfare organizations, thorough studies on their predictive validity are scarce.

Objective: To examine (1) the predictive validity of a risk assessment instrument that has been widely implemented in the Netherlands, and to examine (2) whether the actuarial risk estimation could be improved and simplified to widen the instrument's applicability to different organizations serving different populations.

Participants And Setting: The sample comprised risk assessments (N = 3,681) performed for families enrolled at one of five child welfare agencies in the Netherlands between January 2015 and December 2017.

It is important to provide treatment for juvenile and young adult violent offenders, since no or (too) late treatment increases the risk of recidivism and persistent aggressive behavior in adulthood. In this study, we investigated the efficacy of the intervention Responsive Aggression Regulation Therapy (Re-ART) Outpatient, which has been developed for adolescents and young adults between 16 and 24 years old with severe aggression problems. This quasi-experimental (pilot) study compared the effects of Re-ART Outpatient (n = 47) with a control group (n = 29) receiving treatment as usual on measures regarding risk of violent recidivism, impulsivity, emotional/personal functioning, family functioning, motivation, handling anger, self-reported problem behavior, coping skills, and cognitive distortions.

Background: Foster children, mostly maltreated in their birth families, may be fostered by parents who know little about the impact of traumatic experiences.

Objective: The present study investigated whether the training for foster parents can break the negative circle of traumatic stress. The hypothesis was that improvement in parents' knowledge on trauma and mind-mindedness would be associated with a reduction of their parenting stress, children's post-traumatic stress symptoms, and behaviour problems.

This pilot study (N = 25) compared the effects of a short, four-month version of Responsive Aggression Regulation Therapy Outpatient (Re-ART Compact) and the entire, ten-month intervention (Re-ART Complete) on specific executive functioning (EF) and the risk of violent recidivism in adolescents and young adults (13-23 years). Re-ART is a cognitive behavioral-based intervention for adolescents and young adults with severe aggression problems. The Re-ART Compact and Re-ART Complete groups were comparable on the EF measures inhibition, flexibility, emotion regulation, self-evaluation, and self-control, but the Re-ART Complete group showed more improved risk of violent recidivism.

Background: Theories on the etiology of child maltreatment generally focus on the interaction between multiple risk and protective factors. Moreover, the quadratic model of cumulative risk describes a threshold at which the risk of child maltreatment increases exponentially, suggesting a synergistic effect between risk factors.

Objective: This study explored the interrelatedness of risk factors for child maltreatment.

Today's smartphones allow for a wide range of "big data" measurement, for example, ecological momentary assessment (EMA), whereby behaviours are repeatedly assessed within a person's natural environment. With this type of data, we can better understand - and predict - risk for behavioral and health issues and opportunities for (self-monitoring) interventions. In this mixed-methods feasibility study, through convenience sampling we collected data from 32 participants (aged 16-24) over a period of three months.
