Relationships between Social Information Processing and Aggression among Adolescent Girls with and without ADHD.

Abstract

This study investigated the relationship between social information processing and both relational and physical aggression in a longitudinally-followed sample of 228 adolescent girls (ages 11-18; 140 with ADHD and 88 comparison girls). During childhood, girls participated in naturalistic summer camps where peer rejection, overt physical aggression, and relational aggression were assessed via multiple informants and methods. Approximately 4.5 years later, these girls participated in follow-up assessments during which they completed a commonly-used vignette procedure to assess social information processing; overt and relational aggression were again assessed through multiple informants. Correlations between (a) overt and relational aggression and (b) maladaptive social information processing were modest in this female adolescent sample. However, relationships between aggression and social information processing were stronger for the comparison girls than for the girls with ADHD. The relevance of social information processing models for adolescent girls and clinical implications of findings are discussed.
