【Objective】 To find out the behavior problems of attention deficit hyperactivity (ADHD) boys and its relation with parents' coping style, and to provide evidence for comprehensive therapy. 【Method】 30 ADHD boys and 30 normal control boys were estimated by Achenbach Child Behavior Checklist and their parents were estimated by Coping Style Questionnaire. 【Results】 The scores of fissility, depression, communication, obsession, hyperactivity, aggression and breach of discipline problems in ADHD boys were significantly higher than normal control boys (P<0.05). The scores of fancying, withdrawal and rationalization in ADHD boys' mother were significantly higher than normal control boys' mother (P<0.05). The score of solving problem in ADHD boys' father was significantly lower than normal control boys' father (P<0.05). Total scores of behavior problems were negatively relative with mother' s score of solving problem and they were positively relative with mother's score of rationalization. Total scores of behavior problems were negatively relative with father's score of solving problem and they were positively relative with father's score of withdrawal and rationalization. 【Conclusions】 The behavior problems of ADHD boys should be paid more attention to. ADHD children need comprehensive therapy including their parents' instruction.
