This mixed methods systematic review and meta-analysis sheds more light on the role parenting practices play in children’s adjustment after war exposure. Specifically, we quantitatively examined whether parenting behavior explained some of the well-known associations between war exposure and children’s adjustment. In addition, we meta-synthesized qualitative evidence answering when and why parenting practices might change for war-affected families. We searched nine electronic databases and contacted experts in the field for relevant studies published until March 2018, identifying 4,147 unique publications that were further screened by title and abstract, resulting in 158 publications being fully screened. By running a meta-analytic structural equation model with 38 quantitative studies (N = 54,372, M age = 12.00, SD age = 3.54), we found that more war-exposed parents showed less warmth and more harshness toward their children, which partly mediated the association between war exposure and child adjustment, that is, post-traumatic stress symptoms, depression and anxiety, social problems, externalizing behavior, and lower positive outcomes (e.g., quality of life). War exposure was not associated with parents’ exercise of behavioral control. By meta-synthesizing 10 qualitative studies (N = 1,042; age range = 0−18), we found that the nature of war-related trauma affected parenting differently. That is, parents showed harshness, hostility, inconsistency, and less warmth in highly dangerous settings and more warmth and overprotection when only living under threat. We conclude that it is both how much and what families have seen that shapes parenting in times of war.

Social skills training (SST) programs for nonclinical children and adolescents are known to have positive effects on social skills, but it remains unclear how distinct training components are related to program effects. This multilevel meta-analysis examines how psychoeducation (i.e., exercises aimed at the transfer of knowledge), psychophysical components (i.e., physical exercises aimed at improving self-confidence and trust in others), skill-building components (i.e., exercises aimed at improving interpersonal skills), and cognitive-emotional components (i.e., exercises aimed at changing emotions and cognitions) are independently related to SST program effects. We extracted data from 97 articles describing 839 effect sizes. Training content data were extracted from 60 corresponding SST programs. Our results showed that SST programs had a positive effect on the development of interpersonal skills and emotional skills in nonclinical samples: d = .369, 95% CI [.292, .447], p < .001. This effect was positively influenced by the inclusion of psychoeducation and skill-building components. The inclusion of psychophysical components and the number of cognitive-emotional components did not influence program effects. For psychoeducation and skill-building components, we observed a curvilinear relationship between intensity and effect size: programs including three to six psychoeducational exercises yielded larger effect sizes compared to programs with more or fewer psychoeducational exercises, and programs with 11 to 20 skill-building exercises outperformed programs with more or fewer skill-building exercises. These findings are an indication that psychoeducational components and skill-building components are related to larger SST program effects, granted that the dosage is right.

Significance Narcissistic individuals feel superior to others, fantasize about personal successes, and believe they deserve special treatment. When they feel humiliated, they often lash out aggressively or even violently. Unfortunately, little is known about the origins of narcissism. Such knowledge is important for designing interventions to curtail narcissistic development. We demonstrate that narcissism in children is cultivated by parental overvaluation: parents believing their child to be more special and more entitled than others. In contrast, high self-esteem in children is cultivated by parental warmth: parents expressing affection and appreciation toward their child. These findings show that narcissism is partly rooted in early socialization experiences, and suggest that parent-training interventions can help curtail narcissistic development and reduce its costs for society. Narcissism levels have been increasing among Western youth, and contribute to societal problems such as aggression and violence. The origins of narcissism, however, are not well understood. Here, we report, to our knowledge, the first prospective longitudinal evidence on the origins of narcissism in children. We compared two perspectives: social learning theory (positing that narcissism is cultivated by parental overvaluation) and psychoanalytic theory (positing that narcissism is cultivated by lack of parental warmth). We timed the study in late childhood (ages 7–12), when individual differences in narcissism first emerge. In four 6-mo waves, 565 children and their parents reported child narcissism, child self-esteem, parental overvaluation, and parental warmth. Four-wave cross-lagged panel models were conducted. Results support social learning theory and contradict psychoanalytic theory: Narcissism was predicted by parental overvaluation, not by lack of parental warmth. Thus, children seem to acquire narcissism, in part, by internalizing parents’ inflated views of them (e.g., “I am superior to others” and “I am entitled to privileges”). Attesting to the specificity of this finding, self-esteem was predicted by parental warmth, not by parental overvaluation. These findings uncover early socialization experiences that cultivate narcissism, and may inform interventions to curtail narcissistic development at an early age.

Most interventions aimed at improving social interactions either target internalising or externalising problem behaviour in children. However, a recent review shows that a transdiagnostic approach might fit better to the diversity of problems within a group and within an individual (comorbidity). We examined the effectiveness of a transdiagnostic intervention, called Topper Training: a cognitive behavioural intervention in the peer group with parents included, that targets both internalising and externalising behaviour problems. A randomised trial with a waiting list control group was conducted, using 132 children with mild to severe psychosocial problems. Children were randomised into 77 intervention and 55 waiting list children (50% boys; age = 8-11 years). GLM repeated measures analyses yielded significant intervention effects directly after the training on parent-reported (but not teacher-reported) emotional symptoms (Cohen's d = .70), peer relationship problems (d = .41), and impact of these problems (d = .59). Significant effects were also found for child-perceived peer victimisation (d = .62), self-esteem (d = .45) and teacher-reported conduct problems (d = .42). Parent-reported effects on emotional, conduct problems and impact of the problems and child-reported effects on self-esteem were clinically relevant. No significant effects of Topper Training were found for prosocial behaviour and bullying. Within-participant t-tests in the intervention group between post-intervention and follow-up indicated that effects extended over a six-month follow-up period. Depression decreased significantly from post-test to follow-up. In conclusion, children with mild to severe internalising and/or externalising problems can benefit from the transdiagnostic Topper Training intervention.

What are the parenting behaviors that shape child compliance? Most research on parent-child interactions relies on correlational research or evaluations of \"package deal\" interventions that manipulate many aspects of parenting at the same time. Neither approach allows for identifying the specific parenting behaviors that shape child compliance. To overcome this, we systematically reviewed and meta-analyzed available evidence on the effects of experimentally manipulated, discrete parenting behaviors-a niche in parent-child interaction research that contributes unique information on the specific parenting behaviors that shape child behavior. We identified studies by systematically searching databases and through contacting experts. Nineteen studies (75 effect sizes) on four discrete parenting behaviors were included: praise, verbal reprimands, time-out, and ignore. In multilevel models, we tested for each parenting behavior whether it increased child compliance, including both observed and parent-reported measures of child compliance. Providing \"time-out\" for noncompliance robustly increased both observed and parent-reported child compliance (ds = 0.84-1.72; 95% CI 0.30 to 2.54). The same holds for briefly ignoring the child after non-compliance (ds = 0.36-1.77; 95% CI 0.04 to 2.90). When observed and parent-reported outcomes were combined, but not when they were examined separately, verbal reprimands also increased child compliance (d = 0.72; 95% CI 0.26 to 1.19). Praise did not increase child compliance (ds = -0.27-1.19; 95% CI -2.04 to 1.59). Our findings suggest that of the discrete parenting behaviors that are experimentally studied in multiple trials, especially time-out and ignore, and to some extent verbal reprimands, shape child compliance.

Conduct problems can develop into behavior disorders and put children at risk for other mental health problems. Parenting interventions have been shown to successfully reduce conduct problems and are often expected to prevent the development of broader mental health problems. Few studies have evaluated the longer-term and broader effects of these interventions. To what extent are parenting intervention effects sustained in the years after the intervention? And do effects pertain to conduct problems specifically, or do they also affect broader aspects of children’s mental health? We used a randomized controlled trial to assess the longer-term (2.5 years) effects of the Incredible Years parenting intervention on children’s conduct problems in an indicated prevention setting (N = 387; 79% retention rate). Using a multi-method (survey and computerized tasks) and multi-informant (parents, teachers, and children) approach, we tested whether initial effects on conduct problems were sustained, and whether Incredible Years had broader effects on children’s peer problems, emotional problems, attention-deficit/hyperactivity disorder (ADHD) symptoms, attention and inhibition deficits, and service use. Incredible Years, relative to control (no intervention), led to sustained reductions in parent-reported conduct problems (Cohen’s d = 0.31), but not teacher- and child-reported conduct problems. There were no broader benefits: Incredible Years did not reduce children’s peer problems, emotional problems, ADHD-symptoms, attention and inhibition deficits, or their service use. Improvements in parents’ perceptions of child conduct problems sustained until 2.5 years later. Our findings do not show benefits of Incredible Years as a preventive intervention for children’s broader mental health.

An earlier meta-analysis and review indicated that trauma exposure may be related to lower levels of executive functioning in youth. Since different developmental trajectories were found for three core executive functions, the present study focused on working memory, inhibition, and cognitive flexibility specifically. We conducted a multi-level meta-analysis on 55 studies and 322 effect sizes published between 2001 and 2017 that were retrieved from MEDLINE, Embase, and PsycINFO. The 8070 participants in selected studies were aged 2-25 years. We investigated whether the association between constructs would be moderated by trauma-specific moderators (onset, duration, and type), and study (age, gender, ethnicity, and socio-economic status) and measurement (quality) characteristics. We found small to medium effect sizes for working memory (d = −0.49), inhibition (d = −0.46), and cognitive flexibility (d = −0.44). Moderator analyses showed that, for working memory, when studies used low-quality measurements the effect size was significantly stronger than when studies used high-quality measurements.Compared to single trauma-exposed youth, violence-exposed/abused and foster care/adopted youth showed more problems in inhibition, and foster care/adopted youth showed more problems in cognitive flexibility. Our findings imply that trauma-exposed youth have lower levels of executive functions. Clinical practice should incorporate problems in executive functioning, especially working memory, inhibition, and cognitive flexibility, in assessment and treatment guidelines.

BackgroundThe societal costs associated with juvenile delinquency and reoffending are high, emphasising the need for effective prevention strategies. A promising approach is Youth-Initiated Mentoring (YIM). In YIM, professionals support youths in selecting a non-parental adult from within their social network as their mentor. However, until now, little (quasi-)experimental research has been conducted on YIM in the field of juvenile delinquency. We will examine the effectiveness, working mechanisms, and implementation of YIM as a selective prevention strategy for juvenile delinquents.MethodsThis multiple-methods study consists of a quasi-experimental trial and a qualitative study. In the quasi-experimental trial, we aim to include 300 juvenile offenders referred to Halt, a Dutch juvenile justice system organisation which offers youths a diversion program. In the Netherlands, all juvenile offenders between 12 and 18 years old are referred to Halt, where they must complete the Halt intervention. Youths will be non-randomly assigned to region-matched non-YIM-trained and YIM-trained Halt professionals implementing Care as Usual (CAU, i.e., the Halt intervention) or CAU plus YIM, respectively. Despite non-random allocation, this approach may yield comparable conditions regarding (1) the characteristics of professionals delivering the intervention and (2) case type and severity. Youth and caregiver(s) self-report data will be collected at pre-and post-test and a 6-month follow-up and complemented with official Halt records data. Multilevel analyses will test whether youths following CAU plus YIM show a stronger increase in resilience factors and a stronger decline in the need for formal support and delinquency than youths following CAU. In the qualitative study, we will organise focus group interviews with YIM-trained professionals to explore boosters and barriers experienced by professionals during the implementation of YIM.DiscussionThe proposed study will help identify the effectiveness of YIM in strengthening resilience factors and possibly decreasing juvenile delinquency. In addition, it may offer insights into how and for whom YIM works. Finally, this study can help strengthen the implementation of YIM in the future.Trial RegistrationClinicalTrials.Gov (# NCT05555472).

Children vary in the extent to which they benefit from parenting programs for conduct problems. How does parental mental health change if children benefit less or more? We assessed whether changes in conduct problems and maternal depressive symptoms co-occur following participation in the Incredible Years parenting program. We integrated individual participant data from 10 randomized trials ( N = 1280; children aged 2–10 years) and distinguished latent classes based on families' baseline and post-test conduct problems and maternal depressive symptoms, using repeated measures latent class analysis (RMLCA) and latent transition analysis (LTA). Classes differed mainly in severity of conduct problems and depression (RMLCA; 4 classes). Conduct problems reduced in all classes. Depressive symptoms did not change in most classes, except in a class of families where conduct problems and depression were particularly severe. Incredible Years led to a greater likelihood of families with particularly severe conduct problems and depression moving to a class with mild problems (LTA; 3 classes). Our findings suggest that for the majority of families, children's conduct problems reduce, but maternal depressive symptoms do not, suggesting relative independence, with the exception of families with severe depression and severe conduct problems where changes for the better do co-occur.

ObjectivesAccumulating research provides support for differential susceptibility, which holds that the same children who are most vulnerable to adversity, such as negative parenting, may also benefit most from enriched environments, such as positive parenting. This “for better and for worse” phenomenon is believed to be rooted in endogenous, biological susceptibility factors such as genes, and cognitive and physiological endophenotypes (e.g., heart rate variability and skin conductance). The goal of this paper is to discuss the effect of this biological perspective on children’s susceptibility, and the inclusion of genetic and endophenotypical data in parenting research to shed light on the differential effects of parenting behavior We discuss a number of conceptual and methodological issues related to prior studies that have aimed to assess this.MethodsWe review and discuss current and future perspectives on children’s genetic- and endophenotype-based differential susceptibility to parenting, and experimental study designs that can adequately assess the within-person phenomenon of differential susceptibility.ResultsWe summarize our call for research in an experimental paradigm to test children’s gene- and endophenotype-based differential susceptibility to parenting in their development of externalizing behavior.ConclusionsHereby we aim to advance our understanding of the biological mechanisms underlying children’s differential susceptibility to negative and positive parenting.
