Lowered social motivation is associated with adolescent attention deficit hyperactivity disorder and social anxiety symptoms

Background: Difficulties in social skills are highly prevalent in children and adolescents with attention deficit hyperactivity disorder (ADHD), however, the reasons for these social difficulties are poorly understood. This study aimed to understand social motivation in children (aged 5–8) and adolescents (aged 13–17) with and without ADHD, and the relationship between social anxiety and social motivation in youth with ADHD. Method: 204 parents of children and adolescents with and without ADHD completed online questionnaires on social motivation, social anxiety, and ADHD symptoms. Results: Adolescents with ADHD had significantly lower social motivation than typically developing adolescents, and children with ADHD. Higher social anxiety significantly predicted lowered social motivation in participants with ADHD. Conclusions: These findings indicate a unique pattern of social motivation in ADHD, specifically a reduction during adolescence, reflecting social intervention inefficacy. Additionally, these findings establish a link between social motivation and social anxiety, suggesting that they may act as barriers to social intervention.
