Editors' Introduction to the Special Issue: New Findings on Family Factors in Juvenile Delinquency Prevention.

Juvenile delinquency is a serious societal problem with detrimental physical and mental health effects for both victims and offenders. To prevent onset of delinquent behavior or keep it from escalating in frequency and seriousness, effective prevention is imperative. Since the family entails the primary context in which juvenile development takes place, families have a pivotal role in the prevention of juvenile delinquency.

A Three-level Meta-analysis on the Alliance-Outcome Association in Child and Adolescent Psychotherapy.

Previous meta-analyses have found small to moderate associations between child-therapist alliance and treatment outcomes. However, these meta-analyses have not taken into account changes in alliance (i.e.

Childhood adversity and vagal regulation: A systematic review and meta-analysis.

Childhood adversity (CA) is associated with increased risk for physical and mental health problems, with alterations in vagal regulation (an aspect of autonomic functioning indexed by vagally-mediated heart rate variability [vmHRV]) implicated as a mechanism. Three-level meta-analyses were conducted to synthesize research on the relationship between CA and 1) baseline vagal activity, and 2) vagal reactivity to challenges including stress tests, emotion-eliciting tasks and cognitive tasks. No significant overall association was found between CA and vagal activity (r = -.

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.

Heart-wired to be cold? Exploring cardiac markers of callous-unemotional traits in incarcerated offenders.

Elevated callous-unemotional (CU) traits have been repeatedly identified in a subgroup of offenders that displays severe antisocial behavior; establishing physiological markers may help improve early identification and treatment efforts. This study examines to what extent baseline-resting heart rate (HR) and heart rate variability (HRV) can be used as markers of CU in incarcerated juvenile and adult offenders. CU traits were assessed using the Inventory of Callous-Unemotional traits.

The Role of Personal Resilience and Interpersonal Support in Building Fulfilling and Prosocial Lives: Examining the Good Lives Model among Young Women Four Years after Youth Detention.

Despite growing interest in strength-based rehabilitation frameworks, relevant internal/external resources that are likely to facilitate the rehabilitation of detained female adolescents (DFA) have been understudied. This study aims to fill this gap by studying the role of young women's personal resilience and interpersonal support in building fulfilling and prosocial lives 4 years after youth detention, thereby examining the strength-based good lives model (GLM). Forty-nine former DFA ( = 20.

A Quasi-Experimental Study on the Effectiveness of Dutch Cell Dogs in Incarcerated Youth.

This study examined the effectiveness of Dutch Cell Dogs (DCD), a prison-based dog training program that aims to improve socioemotional functioning of incarcerated youth by giving them the opportunity to train a shelter dog. Primary (aggression and institutional infractions) and secondary (wellbeing and therapeutic functioning) outcomes were assessed for the intervention ( = 61) and comparison group ( = 77) before the start of DCD, after 4 weeks, and after 8 weeks at posttest. Overall, DCD participation was not effective.

Effects of Awareness Programs on Juvenile Delinquency: A Three-Level Meta-Analysis.

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.

Risk factors for child sexual abuse victimization: A meta-analytic review.

Experiencing child sexual abuse (CSA) is a major public health problem with serious consequences for CSA victims. For effective assessment and (preventive) intervention, knowledge on risk factors and their effects is crucial. Here, the aim was to synthesize research on associations between (putative) risk factors and CSA victimization.

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).

The Long-Term Effects of the Youth Crime Prevention Program "New Perspectives" on Delinquency and Recidivism.

New Perspectives (NP) aims to prevent persistent criminal behavior. We examined the long-term effectiveness of NP and whether the effects were moderated by demographic and delinquency factors. At-risk youth aged 12 to 19 years were randomly assigned to the intervention group (NP, n = 47) or care as usual (CAU, n = 54).

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.

The Influence of Treatment Motivation on Outcomes of Social Skills Training for Juvenile Delinquents.

This study examined the influence of treatment motivation on posttreatment effectiveness of an outpatient, individual social skills training for juvenile delinquents imposed as a penal sanction. Propensity score matching was used to match a control group of juveniles receiving treatment as usual ( n = 108 of total N = 354) to a treatment group of juveniles receiving Tools4U, a social skills training with a parental component ( N = 115). Treatment motivation was examined as a moderator and predictor of treatment effects on impulsivity, social perspective-taking, social problem-solving, lack of critical reasoning, developmental task-related skills, and parenting skills.

Quality of life in relation to future mental health problems and offending: Testing the good lives model among detained girls.

Detained girls bear high levels of criminal behavior and mental health problems that are likely to persist into young adulthood. Research with these girls began primarily from a risk management perspective, whereas a strength-based empowering perspective may increase knowledge that could improve rehabilitation. This study examines detained girls' quality of life (QoL) in relation to future mental health problems and offending, thereby testing the strength-based good lives model of offender rehabilitation (GLM).

Risk factors for persistent delinquent behavior among juveniles: A meta-analytic review.

Multiple risk domains have been identified for life-course persistent (LCP) offending, but a quantitative review of the effect of different risk domains was not yet available. Therefore, we performed a series of multilevel meta-analyses to examine the effect of several risk domains for LCP offending relative to adolescence-limited (AL) offending. We included 55 studies reporting on 1014 effects of risk factors, and classified each factor into one of 14 risk domains.

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 problems, and aggression were collected by means of self-report measures and structural equation models were used to test mediation models.

Adolescent-Parent Attachment and Externalizing Behavior: The Mediating Role of Individual and Social Factors.

The aim of this study was to test whether the associations between adolescent-parent attachment and externalizing problem behavior of adolescents were mediated by adolescent cognitive distortions, self-esteem, parental monitoring and association with deviant peers. A total of 102 adolescents (71 % male; aged 12-19 years) at risk for developing delinquent behaviors reported on attachment, parental monitoring, aggressive and delinquent behavior and peers. Mediation effects were tested by using structural equation modeling.

The effects of the prevention program 'New Perspectives' (NP) on juvenile delinquency and other life domains: study protocol for a randomized controlled trial.

Background: New Perspectives (NP) is a prevention program aiming to prevent that youth at onset of a criminal career will develop a persistent criminal behaviour pattern. The effects of NP on juvenile delinquency and other life domains are investigated, using a randomized controlled trial (RCT).

Method/design: In the present study at-risk youth aged 12 to 23 years are assigned randomly to the intervention (N = 90, NP) or control condition consisting of care as usual (N = 90, CAU).

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.

A systematic review of financial debt in adolescents and young adults: prevalence, correlates and associations with crime.

Financial debt in young people has increased in recent years. Because debt may have severe consequences, and it may enhance criminal behavior, insight into the prevalence and determinants of debt and its association with crime is important. We conducted a systematic review and meta-analysis of 36 manuscripts to examine the prevalence of financial debt (k = 23), correlates and risk factors of debt (k = 16), and associations between debt and criminal behavior in adolescents and young adults (k = 8).

Differences between juvenile offenders with and without substance use problems in the prevalence and impact of risk and protective factors for criminal recidivism.

Background: Little is known about the needs of substance-using juveniles in treatment aimed at reducing criminal recidivism. Therefore, we aimed to examine treatment needs of substance-using juvenile offenders.

Methods: Differences were examined between juvenile offenders who abstain from substance use (ASU; n=1974) and substance-using juvenile offenders without (SU; n=7000) and with substance use problems (SUP; n=3317), in the prevalence of risk/protective factors for criminal recidivism and strength of associations between risk/protective factors and criminal recidivism.

A meta-analytic review on treatment dropout in child and adolescent outpatient mental health care.

A large proportion (28% up to 75%) of the treatments in youth mental health care results in premature termination (dropout). It is important to gain knowledge of the determinants of dropout because it can have very severe consequences. The aim of our meta-analytic review was to provide an overview of findings from empirical studies on this subject.

Service referral for juvenile justice youths: associations with psychiatric disorder and recidivism.

Secondary multiple regression analyses related disorder profile, probation officers' mental health/substance use service referrals, and recidivism in 361 juvenile justice youths. Those with externalizing (disruptive behavior or substance use) disorder or substance offenses were most likely to receive service referrals. Substance disordered youths with service referrals had lower recidivism risk compared to counterparts without referrals; referral lowered the recidivism odds to approximately that for youths without a substance use disorder.

A meta-analysis of attachment to parents and delinquency.

To investigate the link between attachment to parents and delinquency, and the potential moderating effects of age and sex, 74 published and unpublished manuscripts (N = 55,537 participants) were subjected to a multilevel meta-analysis. A mean small to moderate effect size was found (r = 0.18).

Maternal and paternal parenting styles: unique and combined links to adolescent and early adult delinquency.

The present study examines the cross-sectional and longitudinal associations between fathers' and mothers' parenting styles and male and female delinquency using a sample of 330 Dutch families with a mid or late adolescent son or daughter (ages 14-22), followed across two measurement waves with a 5-year interval. Parenting styles of fathers and mothers were linked to delinquency. A significant parenting style by sex interaction was found: neglectful parenting was related to higher levels of delinquency in males and permissive parenting was linked to delinquency in females.
