The present study examined the relationships between ethnicity, peer-reported bullying and victimization, and whether these relationships were moderated by the ethnic composition of the school classes. Participants were 2386 adolescents (mean age: 13 years and 10 months; 51.9% boys) from 117 school classes in the Netherlands. Multilevel analyses showed that, after controlling for the ethnic composition of school class, ethnic minority adolescents were less victimized, but did not differ from the ethnic majority group members on bullying. Victimization was more prevalent in ethnically heterogeneous classes. Furthermore, the results revealed that ethnic minority adolescents bully more in ethnically heterogeneous classes. Our findings suggest that, in order to understand bullying and victimization in schools in ethnically diverse cultures, the ethnic background of adolescents and the ethnic composition of school classes should be taken into account.

Parenting programs are the recommended strategy for the prevention and treatment of disruptive child behavior. Similar to most psychosocial interventions, it is unknown which components of parenting programs (ie, parenting techniques taught) actually contribute to program effects. Identifying what parents need to be taught to reduce disruptive child behavior can optimize intervention strategies, and refine theories on how parenting shapes disruptive child behavior. Method: In two meta-analyses, we updated the evidence-base for effectiveness of parenting programs delivered at various levels of prevention and treatment of disruptive behavior. We searched six databases (eg, PsycINFO, MEDLINE) for randomized trials and coded the parenting techniques taught in each program. We identified the techniques associated with program effects in general, and for prevention versus treatment, and immediate versus longer-term effects, specifically. Results: Parenting program effects on disruptive behavior gradually increased per level of prevention (universal d ¼ À0.21, selective d ¼ À0.27, indicated d ¼ À0.55) and treatment (d ¼ À0.69) (Meta-Analysis 1: 154 trials, 398 effect sizes). Three of 26 parenting techniques were associated with stronger program effects: positive reinforcement, praise in particular, and natural/logical consequences. Several additional techniques (eg, relationship building and parental self-management) were associated with stronger effects in treatment but weaker effects in prevention. No techniques were associated with stronger longer-term effects (Meta-Analysis 2: 42 trials, 157 effect sizes). Conclusion: Positive reinforcement and nonviolent discipline techniques (eg, applying natural/logical consequences) seem to be key parenting program techniques to reduce disruptive child behavior. Additional techniques (eg, parental self-management skills) might improve program effects in treatment, but not in prevention.

To establish what it takes to forgive, the present research focused on the cognitive underpinnings of the forgiveness process. We conducted four studies that examined and supported the prediction that executive functioning (a set of cognitive control processes) facilitates forgiveness. First, a correlational study revealed a positive relation between executive functioning and dispositional forgiveness (Study 1). Second, a longitudinal study demonstrated that executive functioning predicts the development of forgiveness over a period of 5 weeks after the offense (Study 2). Finally, two experiments examined when and why executive functioning facilitates forgiveness. Specifically, and in line with predictions, Studies 3 and 4 showed that executive functioning facilitates forgiveness only in the case of relatively severe (as compared with mild) offenses. Furthermore, Study 4 provided evidence for a psychological mechanism underlying the relation between executive functioning and forgiveness by demonstrating the mediating role of rumination about the offense. Implications of these findings for the literature on forgiveness and the role of executive functioning in interpersonal relationships more generally are discussed.

We examined whether anxiety sensitivity, hopelessness, sensation seeking, and impulsivity (i.e., revised version of the Substance Use Risk Profile Scale) would be related to the lifetime prevalence and age of onset of alcohol, tobacco, and cannabis use, and to polydrug use in early adolescence. Baseline data of a broader effectiveness study were used from 3,783 early adolescents aged 11–15 years. Structural equation models showed that hopelessness and sensation seeking were indicative of ever-used alcohol, tobacco or cannabis and for the use of more than one substance. Furthermore, individuals with higher levels of hopelessness had a higher chance of starting to use alcohol or cannabis at an earlier age, but highly anxiety sensitive individuals were less likely to start using alcohol use at a younger age. Conclusively, early adolescents who report higher levels of hopelessness and sensation seeking seem to be at higher risk for an early onset of substance use and poly substance use.

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.
