ABSTRACT

Objective: The purpose of this study was to investigate the effects of group Cognitive Orientation to daily Occupational Performance (CO-OP) on occupational performance and social interaction skills with developmental coordination disorder (DCD). Methods: The subjects of the study were 3 children between the ages of 6 and 7 with DCD. They received a group CO-OP intervention of 60 min per session for a total of 10 sessions. To identify the changes in their occupational performance and social interaction, the Canadian Occupational Performance Measure (COPM), Performance Quality Rating Scale (PQRS), Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2), and Evaluation of Social Interaction (ESI) were applied. Results: The results showed the performance and satisfaction levels of the COPM, and PQRS scores in not only trained tasks, but also untrained tasks. The ESI, used to evaluate the social interaction skills, increased significantly. When we examined the change in motor abilities, significant improvement in bilateral coordination was shown for BOT-2. Furthermore, a reinforcement technique to promote a task and verbal motor mnemonic strategy in DSSs was used the most to solve occupational performance problems in children with developmental coordination disorders during group CO-OP intervention. Conclusion: This study provided evidence that the group CO-OP has a positive effect on improving the occupational performance and social interaction skills with those with a developmental coordination disorder.
