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
