Aims To examine the effect of anxiety and parental overprotection on functional somatic symptoms (FSS) in children with attention deficit hyperactivity disorder (ADHD). Method Seventy‐six children and adolescents (aged 6–17) with ADHD and their parents completed a clinical interview about psychiatric and somatic symptoms. Parents also reported about parenting styles. Structural equation modeling (SEM) was used. Results The generalized anxiety, overprotection, and specific phobia variables each had a direct effect on FSS. Conclusions Anxiety symptoms and parental overprotection may play a role in the development of FSS in children with ADHD. Further research is necessary to corroborate our findings.
