Good friendships, bad friends: Friendship factors as moderators of the relation between aggression and social information processing

The primary objective was to examine whether the associations between aggression and social information processing was moderated by friendship quality and the aggressiveness of the best friend. Drawn from a larger normative sample of 5th and 6th graders, 385 children (180 boys) completed questionnaires pertaining to friendship quality and social information processing. Friendship and peer nominations of behaviours were collected. Results revealed positive associations between aggressive behaviour and the endorsement of aggressive coping strategies in cases where the protagonist was an unfamiliar peer. However, one important exception emerged: no significant associations between aggression and aggressive coping were revealed for children with high-quality friendships with aggressive peers. In cases where the protagonist was the best friend, there was a significant relation between aggression and vengeful coping, but only for those participants who had a low-quality friendship with an aggressive friend.
