Two experimental groups carried out skills training for 12 weeks consisting, , (Three sessions per week) and each session 45 minutes. All participants were assessed before and after interventions with Vineland social maturity scale, Emotional Awareness Rieffe, and Conners (Parent form) questionnaires. The result of Covariance analysis test showed that both experimental groups significantly in the total score of social development, emotional development and cognitive development had higher score than the control group, and of course Instructor-based group in social development had better than parent-based group, that demonstrates positive impact of group environments and peers. also parent-based group in emotional development had better than Instructor-based group, that demonstrates dependency between children and parents. These results showed, both interventions help to improve social development, emotional development and cognitive development in children with developmental coordination disorder, instructor based intervention is more beneficial in social development, and parent-based intervention is more beneficial in emotional development.
