Characterizing the Relationship Among the Social Competence Elements in Autistic Adolescents

ABSTRACT Individuals with autism spectrum disorder have significant difficulties in social competence. This study provided empirical evaluation of the theoretical model by Kennedy and Adolphs (2012) positing that social competence relies on an interconnected network of four components: social brain, cognition, behavior, and functioning. Data from 243 youth (69 female, 174 male), age 10–17 years, were used to test the hypothesized mediation effect of social cognition (Theory of Mind) from social brain (event‐related potential markers of face perception and memory) to social behavior (Contextual Assessment of Social Skills) and functioning (Child Behavior Checklist). An additional analysis evaluated whether the structure of the social competence model varied based on the biological sex of the autistic participants. The findings support the conceptual model of social competence where the social brain's contributions to social behavior and functioning are mediated by social cognition, with an additional direct path between the brain and behavior. The relationship among the four components of social competence is not significantly different for autistic males and females. Social competence is best represented as a network of direct and indirect connections among the neural, cognitive, and behavioral components. Thus, focusing on any single element is not sufficient for effective design of novel assessment and treatment approaches in autism. The findings also highlight the importance of self‐initiated active engagement with social cues as a contributor to successful social behavior and functioning in autism.
