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 to give them a chance to achieve their full developmental potential. Governments and the health care system should, therefore, first and foremost invest in safe and stimulating child-rearing environments, informed by scientific research.

Effectiveness of a multidisciplinary treatment with youth-initiated mentoring for youths with mental health needs from multi-problem families: a quasi-experimental study.

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. The InConnection approach is an integrated care program to improve resilience of youths with mental health needs from multi-problem families by connecting professional expertise from multiple disciplines with the informal social network of the youth. Youths are asked to nominate a youth-initiated mentor (YIM) from the supportive adults in their network. METHODS: This quasi-experimental study compared the effectiveness of the InConnection approach to treatment as usual in a sample of 107 families (n = 66 intervention group, n = 41 control group) with n = 115 youths receiving treatment (cases). Youths (n = 102 reports, Mage = 15.59 years), parents (n = 85 reports) and case managers (n = 107 reports) responded to questionnaires four times over 15 months. Using these data, we measured youth resilience as the primary outcome, seven secondary outcomes, and three intermediate outcomes. RESULTS: Latent growth models showed only one significant change in outcomes over time across conditions, namely a decrease in case manager-reported child unsafety, and only two condition effects, which were both parent-reported. Parents in the InConnection group reported improvements over time in youth's emotional and behavioral problems and their own positive parenting, whereas control parents reported no changes (ps ≤ 0.013). DISCUSSION: The treatment conditions were not effective in improving most of the youth and parental outcomes over time, except for child safety reported by the case manager. The InConnection approach only outperformed care as usual on two parent-reported outcomes. Future research should examine for whom and under what circumstances the InConnection approach works more convincingly. TRIAL REGISTRATION: Netherlands Trial Register NL7565.

Research Review: Siblings matter. A multi-level meta-analysis on the association between cannabis use among adolescent siblings.

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- gender pairs). When comparison data of parents' and peers' cannabis use (disorder) were also available in the included studies, separate meta-analyses on associations between parent-youth and peer-youth cannabis use (disorder) were additionally conducted. METHODS: Studies were selected if they included 11- to 24-year-old participants, and investigated associations between cannabis use (disorder) among those youth and their siblings. These studies were retrieved via a search in seven databases (e.g., PsychINFO). A multi-level meta-analysis using a random effects model was performed on the studies, and heterogeneity analyses and moderator analyses were also conducted. PRISMA guidelines were followed. RESULTS: We retrieved 20 studies (most of which originated from Western cultures) with 127 effect sizes for the main sibling-youth meta-analysis and found a large overall effect-size (r = .423), implying that youth had higher cannabis use rates when their sibling used cannabis, and this association was stronger for monozygotic twins and for same-gender sibling pairs. Finally, a medium effect size existed for the associations between parent-youth cannabis use (r = .300) and a large effect size for peer-youth cannabis use (r = .451). CONCLUSIONS: Youth are more likely to use cannabis when their siblings use cannabis. This sibling-youth cannabis use association existed for all sibling constellations, was larger than the association between parent-youth cannabis use, and was similar in magnitude compared to the association between peer-youth cannabis use-suggesting both genetic and environmental influences (e.g., social-learning) between siblings. Hence, it is important not to neglect sibling influences when treating youth cannabis use (disorder).

A Meta-Analysis on Differences and Associations between Alliance Ratings in Child and Adolescent Psychotherapy.

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. Therefore, the present meta-analysis aims to increase knowledge on the degree of convergence and divergence between child, parent, therapist, and observer alliance ratings in child and adolescent psychotherapy. METHODS: A series of three-level meta-analyses of 78 studies was conducted to investigate differences and associations between child, parent, therapist, and observer alliance ratings in child and adolescent psychotherapy. RESULTS: Findings indicated that children and parents in general rated the alliance more positively than their therapists (d = 0.35, d = 0.72, respectively), and that child-therapist and parent-therapist alliance ratings were moderately correlated (r = .32, r = .23, respectively). Associations between child and therapist ratings and observer ratings were moderate to large (r = .43, r = .53, respectively). CONCLUSIONS: It can be concluded that children and parents generally report more positively on the alliance compared to their therapists, which is consistent with research on the alliance in adult populations. The small to moderate associations between alliance ratings indicate that individuals to some extent have a shared perspective on their alliance, and that the various perspectives on alliance should be acknowledged when dealing with children and parents in therapy. Implications for future research are discussed.

Identifying effective moderators of cognitive behavioural trauma treatment with caregiver involvement for youth with PTSD: a meta-analysis.

Children can develop post-traumatic stress disorder (PTSD) and mental health symptoms after traumatic events. This meta-analysis evaluated the influence of moderators of cognitive behavioural trauma treatment (CBTT) with caregiver involvement in traumatized children. A total of 28 studies were included, with 23 independent samples and 332 effect sizes, representing the data of 1931 children (M age = 11.10 years, SD = 2.36). Results showed a significant medium overall effect (d = 0.55, t = 2.478, p = 0.014), indicating CBTT with caregiver involvement was effective in treating PTSD (d = 0.70), with somewhat smaller effect sizes for internalizing, externalizing, social, cognitive and total problems (0.35 < d > 0.48). The positive treatment effect was robust; we found somewhat smaller effect sizes at follow-up (d = 0.49) compared to post-test (d = 0.57) assessments. Furthermore, several sample (i.e. child's age, gender, and trauma event), programme (i.e. the duration of treatment, number of sessions), study (i.e. control condition, type of instrument, informant, type of sample), and publication (i.e. publication year and impact factor) characteristics moderated the treatment outcomes of the child. In sum, the results of our meta-analysis might help to improve the effectiveness of cognitive behavioural trauma treatment for youth with PTSD, and guide the development of innovative trauma interventions that involve caregivers. Implications for theory and practice are discussed.

Cross-age peer mentoring for youth: A meta-analysis.

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. Analyses included six studies and revealed a medium-sized overall effect of cross-age peer mentoring programs (g = 0.45). Several characteristics moderated effect sizes, with larger effects for programs that were conducted outside of the school setting (i.e., weekend, summer, or in community settings), conducted in urban settings, and had moderate/high levels of adult oversight and supervision. Results highlight the potential benefits of cross-age peer mentoring for youth.

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; SD = 2.44 years), who completed an online questionnaire about their compliance to measures, resilience, coping strategies, mental health, and availability of a natural mentor. Results showed that youth with fewer depressive symptoms adhered better to measures of social distance. Youth who were less suspicious, more resilient, and those with an active coping strategy or a natural mentor more often complied with COVID-19 measures. These results can be used to help youth comply with the COVID-19 measures.

Youth Initiated Mentoring: A Meta-analytic Study of a Hybrid Approach to Youth Mentoring.

Youth initiated mentoring is a hybrid approach that empowers youth to identify and recruit natural mentors, potentially combining the strengths of informal mentoring relationships with the infrastructure and support provided by formal mentoring programs. This meta-analytic review examined the association between youth-initiated programs and youth outcomes across four domains: academic and vocational functioning, social-emotional development, physical health, and psychosocial problems. Results indicated that youth-initiated programs are significantly associated with positive youth outcomes. There was a small-to-medium effect size of g = 0.30 for youth-initiated programs overall, which was based on 14 studies with 11 independent samples (3594 youth and 169 effect sizes) from 2006 to 2019. The effect size was somewhat larger (g = 0.40) when controlling for possible selection bias, and was moderated by participant gender and year of publication. Implications for theory and practice regarding this relatively new approach to mentoring are discussed.

Development and validation of the Attachment Relationship Inventory-Caregiver Perception 2-5 years (ARI-CP 2-5): Psychometric structure, external validity, and norms.

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 caregivers of 2- to 5-year-old children were collected, and a subsample of 83 caregivers participated in an observation study. Confirmatory factor analysis confirmed a four-factor structure of secure, avoidant, ambivalent, and disorganized attachment relationship. Indications of configural, metric, and scalar invariance were found for caregivers' and children's sex, children's age, and population (clinical vs. general population). The four scales showed sufficient internal consistency and significant associations with children's psychopathology, caregivers' general attachment representations, caregivers' mind-mindedness, and population type. Moreover, preliminary evidence for convergent validity with observational attachment measures was found. It is concluded that the ARI-CP 2-5 is a valid instrument that can be used as part of the screening and assessment of insecure attachment relationships.

Hacen falta instrumentos que evalúen las relaciones de afectividad niño-cuidador en la temprana niñez para ser usados en la práctica que se basa en la afectividad, en particular desde la perspectiva del cuidador, lo cual es un factor clave de importancia clínica para tomar en cuenta en las intervenciones de crianza que se enfocan en niños pequeños. Por tanto, se desarrolló el Inventario de la Relación Afectiva - Percepción del Cuidador 2-5 años, que consta de 48 aspectos (ARI-CP 2-5). Se recogió información de encuesta de 446 cuidadores de niños de 2 a 5 años de edad, y un subgrupo muestra de 83 cuidadores participó en un estudio de observación. Los análisis de factores confirmatorios corroboraron una estructura de cuatro factores de la relación de afectividad que es segura, la que evita, la ambivalente y la desorganizada. Se encontraron indicaciones de invariabilidad en el aspecto configuracional, métrico y de escala en cuanto al género sexual de los cuidadores y del niño, la edad del niño, y la población (clínica y general). Las cuatro escalas mostraron una suficiente consistencia interna y asociaciones significativas con la sicopatología de los niños, las representaciones generales de afectividad del cuidador, la conciencia mental de los cuidadores, así como el tipo de población. Es más, se encontró una evidencia preliminar para la validez convergente con las medidas de afectividad de observación. Se concluye con que el ARI-CP 2-5 es un instrumento válido que puede usarse como parte de la detección y evaluación de las relaciones de afectividad inseguras.

Il y a un manque d'instruments évaluant les relations d'attachement enfant-aidant naturel dans la petite enfance pouvant être utilisés dans une pratique basée sur l'attachement, en particulier sur la perception de l'aidant naturel, qui est un facteur important de l'importance clinique à prendre en compte dans les interventions de parentages ciblant les jeunes enfants. Par conséquent l'Inventaire de 48 articles de la Relation d'Attachement - Perception de l'Aidant Naturel 2-5 ans (abrégé en anglais ARI-CP 2-5) a été développé. Les données de sondage de 446 aidants naturels d'enfants de 2 à 5 ans ont été recueillies et un sous-échantillon de 83 aidants naturels ont participé à une étude d'observation. Une analyse factorielle confirmatoire a confirmé une structure à quatre facteurs de la relation d'attachement sécure, évitant, ambivalent et désorganisé. Des indications d'invariance configurale, métrique et scalaire ont été trouvées pour le sexe des aidants naturels et des enfants, l'âge des enfants, et la population (clinique par rapport à population générale). Les quatre échelles ont démontré une cohérence interne suffisante et des associations importantes avec la psychopathologie des enfants, les représentations de l'attachement générale des aidants naturels, l'esprit-qualité mentale et le type de population. De plus une preuve préliminaire de validité convergente ave les mesures observationnelles d'attachement a été trouvée. Nous concluons que l'ARI-CP 205 est un instrument valide qui peut être utilisé pour le dépistage et l'évaluation de relations d'attachement insécures.

Effectiveness and working mechanisms of the InConnection approach in multi-problem families: study protocol of a mixed-methods study.

BACKGROUND: Multi-problem families face problems in several domains that are often found to be chronic and intergenerational. Effective mental health care for youth from these families is currently lacking, urging research on new methods. The InConnection approach is an integrated care program to improve resilience in multi-problem families by connecting the professional expertise from multiple disciplines with the informal social network of the youth. Specifically, youth are asked to nominate a youth initiated mentor (YIM) from among the supportive adults in their network. The aim of this protocol is to describe the design of a mixed-methods study to examine the effectiveness and working mechanisms of the InConnection approach. METHOD/DESIGN: The effectiveness of the InConnection approach is studied in a quasi-experimental questionnaire study using propensity score matching, with N = 300 families with youth aged 10-23 years receiving treatment in either the intervention group (InConnection approach) or the control group (care as usual). The main outcome variables include youth resilience (primary), youth mental health, parental functioning, and the number, duration and types of out-of-home placements. Mediators, moderators, and predictors of effectiveness are examined. Assessments take place at the start of the care program and after three, nine and 15 months. Additionally, semi-structured interviews are conducted with families who have and have not nominated a YIM to understand why some families successfully nominate a YIM, whereas others do not. DISCUSSION: Effective care for youth in multi-problem families is urgently needed. Given its flexibility and accessibility to suit all youth aged 10-23 years from multi-problem families, and its low costs compared to out-of-home placements, the InConnection approach seems an appealing approach to support these families. The current study will provide information on the effectiveness of the InConnection approach. Strengths of this study include its robust design, the ecological validity, and the inclusion of possible mediators, predictors, and moderators of treatment effects.

Non-Specific versus Targeted Approaches to Youth Mentoring: A Follow-up Meta-analysis.

Despite decades of increased research and funding, youth mentoring programs, overall, yield small effects on youth outcomes. As a result, there are growing calls for programs to utilize the mentoring relationship as context for intentional, targeted skills development, in which mentors employ targeted skills designed to match the presenting concerns of mentees. This targeted approach contrasts with the historically dominant, non-specific friendship model, which holds that a supportive relational bond-alone-promotes positive developmental change. The current study is a follow-up meta-analysis using a comprehensive dataset of all intergenerational, one-on-one mentoring program evaluations published between 1975 and 2018, investigating the comparative impact of targeted, skills-based versus non-specific, relational approaches to mentoring. Analyses of 48 mentoring studies of youth outcomes (average youth age of 12.25 years old) revealed the overall effect size of targeted programs to be more than double that of non-specific relational approaches, with significant moderator effects on academic, psychological, and social functioning. Findings suggest that youth mentoring programs can promote positive outcomes, particularly when mentors employ targeted approaches matched to the needs of their mentees.

The Effects of Youth Mentoring Programs: A Meta-analysis of Outcome Studies.

Mentoring programs, which pair youth with caring, non-parental adults with the goal of promoting positive youth development, are an increasingly popular strategy for early intervention with at-risk youth. However, important questions remain about the extent to which these interventions improve youth outcomes. The present study involved a comprehensive meta-analysis of all outcome studies of intergenerational, one-on-one youth mentoring programs written in the English language between 1975 and 2017, using rigorous inclusion criteria designed to align with developmental theories of youth mentoring. Analysis of 70 mentoring outcome studies, with a sample size of 25,286 youth (average age of 12 years old), yielded a statistically significant effect of mentoring programs across all youth outcomes. The observed effect size fell within the medium/moderate range according to empirical guidelines derived from universal prevention programs for youth, and was consistent with past meta-analyses of youth mentoring. Moderation analyses indicated that programs serving a larger proportion of male youth, deploying a greater percentage of male mentors or mentors with a helping profession background, and requiring shorter meetings yielded larger effect sizes, as did evaluations that relied on questionnaires and youth self-report. Taken together, these findings provide some support for the efficacy of mentoring interventions, while also emphasizing the need to remain realistic about the modest impact of these programs as currently implemented, and highlighting opportunities for improving the quality and rigor of mentoring practices.

Participatory Peer Research in the Treatment of Young Adults With Mild Intellectual Disabilities and Severe Behavioral Problems.

This study provides an illustration of a research design complementary to randomized controlled trial to evaluate program effects, namely, participatory peer research (PPR). The PPR described in current study was carried out in a small sample (N = 10) of young adults with mild intellectual disabilities (MID) and severe behavioral problems. During the PPR intervention, control and feedback to individuals is restored by training them to become participant-researchers, who collaborate in a small group of people with MID. Their research is aimed at the problems the young adults perceive and/or specific subjects of their interest. The study was designed as a multiple case study with an experimental and comparison group. Questionnaires and a semistructured interview were administered before and after the PPR project. Results of Reliable Change Index (RCI) analyses showed a decrease in self-serving cognitive distortions in the PPR group, but not in the comparison group. These results indicate that PPR helps to compensate for a lack of adequate feedback and control, and in turn may decrease distorted thinking and thereby possibly later challenging behavior.

Internal structure and reliability of the Attachment Insecurity Screening Inventory (AISI) for children age 6 to 12.

BACKGROUND: The aim of the present study was to examine the internal structure and reliability of the Attachment Insecurity Screening Inventory (AISI) 6-12. The AISI 6-12 years is a parent-report questionnaire for assessing the parents' perspective on the quality of the attachment relationship with their child aged between 6 and 12 years. METHODS: The sample consisted of 681 mothers and fathers reporting on 372 children (72.3% adoption parents, 14.9% non-biological primary care takers including foster parents, and 12.8% biological parents). The internal structure was assessed with multilevel confirmatory factor analyses (CFA) and the reliability of the scores with Cronbach's and ordinal alphas. RESULTS: Multilevel CFA confirmed a three-factor model of avoidant, ambivalent/resistant and disorganized attachment. Multi-group CFA indicated full configural and metric measurement invariance, and partial scalar and strict measurement invariance across mothers and fathers. Reliability coefficients were found to be sufficient. CONCLUSIONS: This study showed the potential of using parental reports in the initial screening of attachment related problems, especially considering the practical approach of parental reports. However, further development of the AISI 6-12 years seems important to increase the validity of the AISI 6-12 years. In addition, future studies are necessary to replicate the current findings, and to strengthen the evidence that the AISI 6-12 years is appropriate for the use in middle childhood and validly assesses the parents' perspective on attachment insecurities in their child.

The effectiveness of Dutch Cell Dogs in correctional facilities in the Netherlands: a study protocol of a quasi-experimental trial.

BACKGROUND: Many former inmates recidivate, resulting in high costs for societies worldwide. Evidence based treatment practices may not work in prisons, due to detainees' lacking motivation, impaired well-being, and an unsafe group environment. One attempt to improve social group climate and well-being is the use of Prison-based Animal Programs (PAP). Using a quasi-experimental design, the aim of the current study is to examine the effectiveness of one such PAP in the Netherlands: Dutch Cell Dogs (DCD). METHODS/DESIGN: Participants (N = 256) from 12 justice centers, including psychiatric, juvenile and adult facilities, will be recruited. Half of the sample (n = 128) will receive DCD training after voluntarily signing up (intervention group); The other half (n = 128) will be recruited to participate in the research and receive treatment-as-usual (TAU/Ccomparison group). Factors related to psychosocial functioning (e.g., self-esteem, empathy, self-control, life satisfaction, attention) and general therapeutic factors (i.e., therapeutic alliance, treatment motivation), expected to contribute to treatment success, will be assessed to measure the effectiveness of DCD. In addition, behavioral problems will be measured as well as recidivism rates. Questionnaires and neuropsychological tests will be employed to measure aforementioned outcome variables. Moreover, physiological data, based on heart rate and cortisol measures, will be collected to provide insight into the functioning of participants' physiological stress response and to determine whether stress reduction occurs over time. Multimethod data collection will occur at pre-training (T1), at 1-month (halfway training/T2), at 2-months (end training/T3), and 6-months after the end of the training (follow up/T4). DISCUSSION: This is the first study to examine the effectiveness of a widely implemented PAP in the Netherlands. Challenges associated with conducting the proposed study are typical for practice based research in correctional settings (e.g., a demanding workload of staff, lack of motivation to participate in research). Study results on the effects of a PAP will have an impact on inmates, justice centers, and municipalities across the Netherlands. TRIAL REGISTRATION: Retrospectively registered.

Cost-effectiveness of Family Group Conferencing in child welfare: a controlled study.

BACKGROUND: This study aimed to examine the short- and long term (cost-) effectiveness of Family Group Conferencing (FGC) compared to care as usual (CAU) in terms of improved child safety, empowerment and social support. METHODS: A subgroup of a larger randomized controlled trial, comprising 69 families in child welfare (experimental group: n = 46; control group: n = 23), was included. RESULTS: No additional effects of FGC on child safety, social support and only short-term positive effects on empowerment were found. There were no differences in costs between FGC and CAU. The chance for FGC to be cost-effective was small. For families who refused FGC, the FGC approach was more cost-effective than CAU, whereas it was less cost-effective for families that prepared or completed FGC. CONCLUSIONS: Overall, FGC is not (cost-)effective in improving child safety, empowerment and social support, but cost-effectiveness varies at different levels of FGC-completion.

Research Review: The effectiveness of multidimensional family therapy in treating adolescents with multiple behavior problems - a meta-analysis.

BACKGROUND: Multidimensional family therapy (MDFT) is a well-established treatment for adolescents showing both substance abuse and/or antisocial behavior. METHOD: The effectiveness of MDFT in reducing adolescents' substance abuse, delinquency, externalizing and internalizing psychopathology, and family malfunctioning was examined by means of a (three-level) meta-analysis, summarizing 61 effect sizes from 19 manuscripts (N = 1,488 participants). RESULTS: Compared with other therapies, the overall effect size of MDFT was significant, albeit small in magnitude (d = 0.24, p < .001), and similar across intervention outcome categories. Moderator analysis revealed that adolescents with high severity problems, including severe substance abuse and disruptive behavior disorder, benefited more from MDFT than adolescents with less severe conditions. CONCLUSIONS: It can be concluded that MDFT is effective for adolescents with substance abuse, delinquency, and comorbid behavior problems. Subsequently, it is important to match specific characteristics of the adolescents, such as extent of impairment, with MDFT.

Sports Participation and Juvenile Delinquency: A Meta-Analytic Review.

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.

Practitioner review: Effective ingredients of prevention programs for youth at risk of persistent juvenile delinquency--recommendations for clinical practice.

BACKGROUND: There is a lack of knowledge about specific effective ingredients of prevention programs for youth at risk for persistent delinquent behavior. The present study combines findings of previous studies by examining the effectiveness of programs in preventing persistent juvenile delinquency and by studying which particular program, sample, and study characteristics contribute to the effects. Information on effective ingredients offers specific indications of how programs may be improved in clinical practice. METHOD: A literature search in PsychINFO, ERIC, PubMed, Sociological Abstracts, Criminal Justice Abstracts, and Google Scholar was performed. Only (quasi)experimental studies and studies that focused on adolescents at risk for (persistent) delinquent behavior were included. Multilevel meta-analysis was conducted on 39 studies (N = 9,084). Participants' ages ranged from 6 to 20 years (M = 14 years, SD = 2.45). RESULTS: The overall effect size was significant and small in magnitude (d = 0.24, p < .001). Behavioral-oriented programs, focusing on parenting skills training, behavioral modeling, or behavioral contracting yielded the largest effects. Multimodal programs and programs carried out in the family context proved to be more beneficial than individual and group-based programs. Less intensive programs yielded larger effects. CONCLUSIONS: Prevention programs have positive effects on preventing persistent juvenile delinquency. In order to improve program effectiveness, interventions should be behavioral-oriented, delivered in a family or multimodal format, and the intensity of the program should be matched to the level of risk of the juvenile.

The development and validation of the Youth Actuarial Care Needs Assessment Tool for Non-Offenders (Y-ACNAT-NO).

BACKGROUND: In The Netherlands, police officers not only come into contact with juvenile offenders, but also with a large number of juveniles who were involved in a criminal offense, but not in the role of a suspect (i.e., juvenile non-offenders). Until now, no valid and reliable instrument was available that can be used by Dutch police officers for estimating the risk for future care needs of juvenile non-offenders. In the present study, the Youth Actuarial Care Needs Assessment Tool for Non-Offenders (Y-ACNAT-NO) was developed for predicting the risk for future care needs that consisted of (1) a future supervision order as imposed by a juvenile court judge and (2) future worrisome incidents involving child abuse, domestic violence/strife, and/or sexual offensive behavior at the juvenile's living address (i.e., problems in the child-rearing environment). METHODS: Police records of 3,200 juveniles were retrieved from the Dutch police registration system after which the sample was randomly split in a construction (n = 1,549) and validation sample (n = 1,651). The Y-ACNAT-NO was developed by performing an Exhaustive CHAID analysis using the construction sample. The predictive validity of the instrument was examined in the validation sample by calculating several performance indicators that assess discrimination and calibration. RESULTS: The CHAID output yielded an instrument that consisted of six variables and eleven different risk groups. The risk for future care needs ranged from 0.06 in the lowest risk group to 0.83 in the highest risk group. The AUC value in the validation sample was .764 (95% CI [.743, .784]) and Sander's calibration score indicated an average assessment error of 3.74% in risk estimates per risk category. CONCLUSIONS: The Y-ACNAT-NO is the first instrument that can be used by Dutch police officers for estimating the risk for future care needs of juvenile non-offenders. The predictive validity of the Y-ACNAT-NO in terms of discrimination and calibration was sufficient to justify its use as an initial screening instrument when a decision is needed about referring a juvenile for further assessment of care needs.
