Efficacy of CO-OP Approach With and Without Parental Coaching: RCT Study Protocol: Efficacité de l’approche CO-OP avec et sans coaching parental : protocole d’essai clinique randomisé

Background. Developmental coordination disorder (DCD) leads to decreased occupational performance and restricted participation. Cognitive Orientation to daily Occupational Performance Approach (CO-OP) is effective, and as parental support is a key element, it seems relevant to investigate. Purpose. To describe a study protocol that will compare CO-OP with and without Occupational Performance Coaching (OPC) on activity and participation of children with DCD. Method. Randomized controlled with seven to 12-year-olds, assigned to either experimental (CO-OP+OPC) or control (CO-OP) group, both receiving traditional CO-OP, with four additional parental group sessions for the experimental group. Key Issues. Actual and perceived occupational performance and satisfaction of children’s chosen goals and participation, motor performance and executive function. Measures will be obtained at baseline, post-intervention, and at 3-month follow-up. Implications. Detailed description of an intervention protocol may help further replication and may contribute to clarify if a boost on parents’ participation promotes better outcomes for children with DCD.
