The Role of Executive Functioning in Predicting Social Competence in Children with and without Autism Spectrum...

All children with autism spectrum disorder (ASD) experience social difficulties but they differ with regard to the type and severity of their challenges. Potentially powerful interventions targeting social skills in children with ASD may have limited effectiveness if they are not tailored to the child's specific needs. One factor that may influence social competence is executive functioning (EF). EF may impact social competence by facilitating higher-order strategies such as emotional and cognitive regulation which are necessary for social interactions. Participants included 132 children and adolescents, aged 7-13, including 77 with ASD (M = 10.11, SD = 1.94), and 55 without ASD (M = 9.54, SD = 1.67). Caregivers completed the Behavior Rating Inventory of Executive Functioning, Version 2 (BRIEF-2) Parent Form, assessing everyday EF skills, and the Multidimensional Social Competence Scale (MSCS). Hierarchical multiple regression analyses were conducted separately for the group without ASD and the group with ASD, with MSCS entered as the dependent variables and EF indices and scales of the BRIEF-2 as the main predictor variables. EF deficits in emotional control predicted poor emotion regulation for both children with and without ASD. For the group without ASD, better emotional control and initiation skills predicted empathic concern and social knowledge, respectively. Challenges in self-monitoring significantly predicted difficulties with social inferencing and social knowledge for children with ASD. The findings highlight the importance of targeting specific EF skills that contribute to various aspects of social competence to increase the effectiveness of interventions for children with ASD.

For children without ASD, emotional control and initiation skills were strongly linked to their displays of empathy and social knowledge, respectively. For children with ASD, their abilities to be aware of their own behaviors and its impact on others were strongly related to their ability to interpret social cues and their social knowledge. For both groups, the ability to regulate their emotions were important predictors of their ability to modulate their emotions in social contexts.
