Objective: To examine the prevalence rates of bullying involvement and their correlates in adolescents diagnosed with ADHD in Taiwan. Method: Bullying involvement, family and ADHD characteristics, the levels of behavioral inhibition system (BIS) and behavioral approach system (BAS), and psychiatric comorbidity were assessed in 287 adolescents with ADHD. The multiple regression analysis was used to examine the correlate of bullying victimization and perpetration. Results: The prevalence rates of the pure victims, pure perpetrators, and victim-perpetrators were 14.6%, 8.4%, and 5.6%, respectively. Young age, a high BIS score, autism spectrum disorders, and low satisfaction with family relationships were associated with severe bullying victimization. A high score of fun seeking on the BAS and low satisfaction with family relationships were associated with severe bullying perpetration. Conclusion: A high proportion of adolescents with ADHD are involved in bullying. Multiple factors are associated with bullying involvement in adolescents with ADHD.
