The Relationship Between Parenting and Delinquency: A Meta-analysis

This meta-analysis of 161 published and unpublished manuscripts was conducted to determine whether the association between parenting and delinquency exists and what the magnitude of this linkage is. The strongest links were found for parental monitoring, psychological control, and negative aspects of support such as rejection and hostility, accounting for up to 11% of the variance in delinquency. Several effect sizes were moderated by parent and child gender, child age, informant on parenting, and delinquency type, indicating that some parenting behaviors are more important for particular contexts or subsamples. Although both dimensions of warmth and support seem to be important, surprisingly very few studies focused on parenting styles. Furthermore, fewer than 20% of the studies focused on parenting behavior of fathers, despite the fact that the effect of poor support by fathers was larger than poor maternal support, particularly for sons. Implications for theory and parenting are discussed.

Trajectories of Delinquency and Parenting Styles

We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10–19, we identified five distinct delinquency trajectories differing in both level and change in seriousness over time: a nondelinquent, minor persisting, moderate desisting, serious persisting, and serious desisting trajectory. More serious delinquents tended to more frequently engage in delinquency, and to report a higher proportion of theft. Proportionally, serious persistent delinquents were the most violent of all trajectory groups. Using cluster analysis we identified three parenting styles: authoritative, authoritarian (moderately supportive), and neglectful (punishing). Controlling for demographic characteristics and childhood delinquency, neglectful parenting was more frequent in moderate desisters, serious persisters, and serious desisters, suggesting that parenting styles differentiate non- or minor delinquents from more serious delinquents.

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). Poor attachment to parents was significantly linked to delinquency in boys and girls. Stronger effect sizes were found for attachment to mothers than attachment to fathers. In addition, stronger effect sizes were found if the child and the parent had the same sex compared to cross-sex pairs of children and parents. Age of the participants moderated the link between attachment and delinquency: larger effect sizes were found in younger than in older participants. It can be concluded that attachment is associated with juvenile delinquency. Attachment could therefore be a target for intervention to reduce or prevent future delinquent behavior in juveniles.

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. We structured the often contradicting results from two perspectives. First, we compared studies with efficacy and effectiveness designs. Second, we compared studies which used a dropout definition based on the opinion of therapists, with those that took the number of predetermined completed sessions as a criterion. Third, we studied three groups of predictors, i.e., pre-treatment child variables, pre-treatment family or parent variables, and treatment and therapist variables or treatment participation barriers. The meta-analytic review showed that dropout percentages were strongly influenced by study design: Percentages were lower in efficacy than in effectiveness studies. Within effectiveness studies, the dropout percentages were lower when the therapists opinion was used rather than when the number of sessions was used as a criterion. In efficacy studies on the contrary, the dropout percentages were similar for studies using the first or the second criterion. With respect to dropout predictors, results were less clear. Some of the dropout predictors were influenced by study design or dropout definition, but for most predictors this influence could not be analyzed because they were not studied in all groups of studies or because the effect sizes were small or non-significant. Treatment and therapist variables or experienced treatment participation barriers were overall stronger dropout predictors than the pre-treatment child variables and pre-treatment family or parent variables, although some strong predictive pre-treatment variables emerged as well.

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 results revealed a significant effect for 11 domains ranging from d=0.200 to d=0.758. Relatively large effects were found for the criminal history, aggressive behavior, and alcohol/drug abuse domains, whereas relatively small effects were found for the family, neurocognitive, and attitude domains. The physical health, background, and neighborhood domains yielded no effect. Moderator analyses showed that effects of sibling-related risk factors were larger than effects of mother-related risk factors, and that the effect of the relationship domain was largest during childhood. We conclude that most risk domains contribute to the development of LCP offending and that differences between AL and LCP offenders may be quantitative rather than qualitative. Implications of the present results for risk assessment and the prevention/treatment of LCP offending are discussed.

Peers and delinquency among girls and boys: Are sex differences in delinquency explained by peer factors?

In this article, we investigate sex differences in the relationship between peers and delinquency. We analyse to what extent peers have different effects on delinquency among girls and boys, and to what extent sex differences in the level of delinquency can be explained by differential exposure or vulnerability to criminogenic peer contexts. Data are used from the School Study of the Netherlands Institute for the Study of Crime and Law Enforcement, in which rich data about peers were collected, including measurements of peer delinquency as reported by nominated peers themselves, time spent with peers, peer attachment, peer pressure and the sex composition of peer networks. The results indicate that, although the characteristics of peer relationships differ in many respects between the sexes, the effects of peers on delinquent behaviour are remarkably similar for girls and boys. Further, it appears that the investigated peer variables explain a substantial part of the sex differences in delinquent behaviour.

Changes in Risk Factors during Adolescence Implications for Risk Assessment

This study examined to what extent the significance of both static and dynamic risk factors for recidivism changes in the course of adolescence. For this purpose, file and interview data of 1,396 juveniles charged with a criminal offense were analyzed. This study showed that the impact of almost all dynamic risk factors decreased as juveniles grew older. As a result, the predictive power of risk assessment models also decreased. From age 14, dynamic risk factors did not contribute significantly to the prediction of recidivism over static risk factors. Another consequence of the declining importance of dynamic risk factors is that the potential effect of an intervention aimed at these factors will also decrease as adolescents grow older, which indicates the importance of early intervention.

Changes in the Relative Importance of Dynamic Risk Factors for Recidivism During Adolescence

This study examined which dynamic risk factors for recidivism play an important role during adolescence. The sample consisted of 13,613 American juveniles who had committed a criminal offense. The results showed that the importance of almost all dynamic risk factors, both in the social environment domain (school, family, relationships) and in the individual domain (attitude, skills, aggressiveness), decreased as juveniles grew older. Therefore, the potential effect of an intervention aimed at these factors will also decrease as juveniles grow older. The relative importance of the risk factors also changed: In early adolescence, risk factors in the family domain showed the strongest association with recidivism, whereas in late adolescence risk factors in the attitude, relationships, and school domain were more strongly related to recidivism. These results suggest that the focus of an intervention needs to be attuned to the age of the juvenile to achieve the maximum potential effect on recidivism.

Long-Term Effects of Parenting and Family Characteristics on Delinquency of Male Young Adults:

Drawing from the criminology literature and family studies, we investigated the long-term effects of established family risk factors and parenting styles on male young adult delinquency. We used data sets from two longitudinal studies, the Pittsburgh Youth Study (N=474) and the Child-Rearing and Family in the Netherlands Study (N=128), each with assessment periods covering at least 10 years. The lack of orderly and structured activities within the family during adolescence was a strong predictor of delinquency in young adulthood, once prior aggression and demographic variables were considered. No evidence was found for a relationship between authoritarian and authoritative parenting styles and later delinquency. Furthermore, previously identified family factors such as socioeconomic status, supervision, punishment and attachment were not related to delinquent behaviour in young adulthood.

The Influence of Mental Health Disorders on Severity of Reoffending in Juveniles

The authors conducted secondary data analyses on mental health assessment and offense history data for 700 juveniles referred to juvenile justice agencies in Alabama (probation and detention). Multiple regression analysis was applied to predict subsequent offense severity by disorder profile, adjusting for prior offense severity and background variables. Juveniles with a substance use disorder with or without co-occurring disorders were at greater risk for escalations in offense seriousness over time. Early in juvenile justice system contact, juveniles should get effective treatment for substance use to prevent offending escalation.
