[Effect of Emotion Regulation on Anxiety/Depression Symptoms in Children With Attention-Deficit/Hyperactivity Disorder: The Mediating Role of Social Problems and the Moderating Role of Family Functioning].

Objective: To investigate the mediating effect of social problems in the effect pathway of emotional dysregulation influencing anxiety/depression emotions in children with attention-deficit/hyperactivity disorder (ADHD) and to explore the potential moderating effect of family functionality.

Methods: A total of 235 children diagnosed with ADHD were enrolled in the study. The paticipants' age ranged from 6 to 12. Emotion Regulation Checklist, Achenbach's Child Behavior Checklist (CBCL) Social Problems Subscale, CBCL Anxious/Depressed Subscale, and Family Assessment Device were used to evaluate the emotional regulation, social problems, anxiety/depression emotions, and family functionality of the participants. A moderated mediation model was employed to analyze whether social problems and family functionality mediate and moderate the relationship between emotional regulation and anxiety/depression emotions.

Results: Social problems partially mediated the impact of emotional dysregulation on anxiety/depression emotions in ADHD children, with the direct effect being 0.26 (95% confidence interval []: [0.17, 0.36], <0.001), the indirect effect being 0.13 (95% : [0.07, 0.19], <0.001), and the mediating effect accounting for 33% of the total effect. Family functionality exhibited a positive moderating effect on the relationship between social problems and anxiety/depression emotions.

Conclusion: This study contributes to the understanding of complex factors influencing anxiety/depression in children with ADHD, providing reference for the further development of targeted interventions for children with ADHD and the improvement of prognosis.
