Objective: To explore the effect of drawing therapy on the behavior of children with attention deficit hyperactivity disorder (ADHD), and to provide a new perspective for the treatment of children with attention deficit hyperactivity disorder (ADHD). Methods: In June 2019, a random sample of three primary schools in 1-6 grade in Baishan who diagnosed with ADHD was recruited, the experimental group 10 ADHD children were given painting therapy intervention for 14 weeks, four times a week, 120 mins each time, the control group 10 ADHD children received no intervention. During the study period all the participants do not receive any other treatment. The ADHD Rating Scale Parent version,the Conners Parents Symptom Questionnaire(PSQ) and the Rey Complex Figure test was assessed before and after the intervention to evaluate the symptoms of ADHD children. Results: In terms of PSQ score test, there were significant differences between the scores of four dimension factors in the experimental group after therapeutic intervention and those before intervention and those after intervention in the control group(P<0.05). The follow-up test showed that the PSQ score in the experimental group remained good (P<0.05). There were two dimension factors that were not significantly different in the post-test and follow-up post-test and before intervention. In Rey complex memory graph test score test, it was found that the score of four dimensions after intervention in the experimental group was significantly different from that before intervention and after intervention in the control group (P<0.05). After 12 weeks, the score of follow-up test remained good (P<0.05). Conclusion Painting therapy has a significant effect on ADHD children’s behavioral management ability and working memory ability, and the effect can last for at least 12 weeks.
