The present study aims to investigate peer victimization and its relationship with comorbid psychiatric diagnoses and quality of life (QoL) among children with attention deficit hyperactivity disorder (ADHD). Study sample consisted of 66 children with ADHD (mean age = 8.6 +/- 1.1 years) and age- and gender-matched 66 controls (mean age = 8.5 +/- 1.3 years). In self-reports, the ADHD group reported significantly higher rates of victimization and bullying than the non-ADHD group. Verbal and physical forms of victimization and bullying were the most prevalent forms in both groups; however, exclusion from peer groups, which is named as relational bullying, was the most significantly differing type between two groups. QoL parameters did not significantly differ between the children involved in bullying and those not involved, except for the lower physical QoL in victimized children in the control group. In conclusion, peer victimization was significantly more prevalent in the ADHD group than the non-ADHD group. Preventive measures are needed for peer victimization, especially for children with ADHD.
