ADHD Symptoms and Sleep Problems During Middle Childhood: The Indirect Effect of Peer Victimization

The present cross-sectional study evaluated whether traditional and/or cyber peer victimization served as mechanisms linking ADHD symptoms to sleep disturbance and sleep impairment in a sample of 284 third- through fifth-grade students (51.9% boys; 50.4% Hispanic/Latine) from two elementary schools in the United States. ADHD symptoms were assessed using teacher ratings. Children provided reports of their traditional and cyber victimization as well as their sleep disturbance and impairment. Results from path analysis models revealed significant indirect effects of traditional victimization on the links from ADHD symptoms to sleep disturbance and impairment. There was also a significant indirect effect of cyber victimization on the link from ADHD symptoms to sleep impairment. These findings suggest that experiences of traditional and cyber peer victimization may need to be addressed among children exhibiting ADHD symptoms in order to mitigate their risk for sleep problems and downstream effects on other domains of psychosocial functioning.
