Social information processing, normative beliefs about aggression and parenting in children with mild intellectual disabilities and aggressive behavior

Background High levels of aggressive behavior in children with mild intellectual disabilities to borderline intellectual functioning (MID-BIF) are associated with deviant social information processing (SIP) steps. The current study investigated deviant SIP as a mediating mechanism linking both children’s normative beliefs about aggression and parenting to aggressive behavior in children with MID-BIF. Additionally, the mediating role of normative beliefs about aggression in linking parenting and deviant SIP was investigated. Methods 140 children with MID-BIF in community care in the Netherlands, their parent(s) or caretaker(s), and their teacher participated in this cross-sectional study. Structural equation modeling was performed to test mediations. Models were run separately for parent and teacher reports of aggression, and included three deviant SIP steps (interpretation, response generation, response selection). Results A total indirect effect through deviant SIP steps was found from normative beliefs about aggression to teacher-reported aggression, but not to parent-reported aggression. An indirect effect was found from positive parenting through normative beliefs about aggression to deviant SIP. Conclusion The results of this study suggest that, next to deviant SIP and parenting, normative beliefs about aggression may be a relevant intervention target for children with MID-BIF and aggressive behavior

ORCHIDS: An observational randomized controlled trial on childhood differential susceptibility

Background: A central tenet in developmental psychopathology is that childhood rearing experiences have a major impact on children’s development. Recently, candidate genes have been identified that may cause children to be differentially susceptible to these experiences (i.e., susceptibility genes). However, our understanding of the differential impact of parenting is limited at best. Specifically, more experimental research is needed. The ORCHIDS study will investigate gene-(gene-)environment interactions to obtain more insight into a) moderating effects of polymorphisms on the link between parenting and child behavior, and b) behavioral mechanisms that underlie these gene-(gene-)environment interactions in an experimental design. Methods/Design: The ORCHIDS study is a randomized controlled trial, in which the environment will be manipulated with an intervention (i.e., Incredible Years parent training). In a screening, families with children aged 4–8 who show mild to (sub)clinical behavior problems will be targeted through community records via two Dutch regional healthcare organizations. Assessments in both the intervention and control condition will be conducted at baseline (i.e., pretest), after 6 months (i.e., posttest), and after 10 months (i.e., follow-up). Discussion: This study protocol describes the design of a randomized controlled trial that investigates gene-(gene-) environment interactions in the development of child behavior. Two hypotheses will be tested. First, we expect that children in the intervention condition who carry one or more susceptibility genes will show significantly lower levels of problem behavior and higher levels of prosocial behavior after their parent(s) received the Incredible Years training, compared to children without these genes, or children in the control group. Second, we expect that children carrying one or more susceptibility genes will show a heightened sensitivity to changes in parenting behaviors, and will manifest higher emotional synchronization in dyadic interchanges with their parents. This may lead to either more prosocial behavior or antisocial behavior depending on their parents’ behavior

Explaining the paradoxical rejectionaggression link: The mediating effects of hostile intent attributions, anger, and decreases in state selfesteem on acute peer rejection-induced aggression in youth.

People are strongly motivated to feel accepted by others. Yet when faced with acute peer rejection they often aggress against the very peers they desire acceptance from, which may lead to further rejection. The present experiment tests three potential mediators of aggressive responses to acute peer rejection in the critical developmental stage of early adolescence. Participants (N=185, M(age)=11.5 years) completed personal profiles that were allegedly evaluated online by peers. After receiving negative or neutral peer feedback, participants could aggress against the same peers who had evaluated them. Rejected participants attributed more hostile intent to the peers, were angrier, showed a greater reduction in state self-esteem, and were more aggressive. Mediational analyses showed that hostile intent attributions mediated the acute peer rejection-aggression relationship, whereas increases in anger and decreases in state self-esteem did not. Thus, acute peer rejection evokes hostile intent attributions that, in turn, lead to aggressive reactions

Self-verification strivings in children holding negative self-views: The mitigating effects of a preceding success experience

Research among adults has consistently shown that people holding negative self-views prefer negative over positive feedback. The present study tested the hypothesis that this preference is less robust among pre-adolescents, such that it will be mitigated by a preceding positive event. Pre-adolescents (n = 75) holding positive or negative global self-esteem were randomized to a favorable or unfavorable peer evaluation outcome. Next, preferences for positive versus negative feedback were assessed using an unobtrusive behavioral viewing time measure. As expected, results showed that after being faced with the success outcome children holding negative self-views were as likely as their peers holding positive self-views to display a significant preference for positive feedback. In contrast, children holding negative self-views displayed a stronger preference for negative feedback after being faced with the unfavorable outcome that matched their pre-existing self-views
