Objectives: Children with attention deficithyperactivity disorder (ADHD) are characterized by short attention spans, impulsiveness and hyperactivity. Therefore, their interpersonal interactions are hindered. An occupational therapy group for children with ADHD was designed to help the children control their impulses and increase their interpersonal interactions using play as the therapeutic medium. Methods: The children's group was led by two occupational therapists. There were 10 children (all boys), aged 6 to 10 years. The 50-minute group was held weekly for 8 weeks. The children's performances were recorded and rated by the therapists using a self-designed rating scale after each session. The parents also used the Conner's rating scale to rate their children's behaviors. Result: Eighty percent of caretakers found their children had better behavior, longer attention spans, reduced activity levels and impulsiveness compared with before the group therapy sessions. Although the differences were not significant, the average rate of improvement was 20.78% after eight sessions. Conclusion: The results suggest that the activity group was beneficial in improving some behaviors of children with ADHD. However, the findings need further investigation. (Full Text in Chinese)
