PLAYshop Randomized Controlled Trial: Efficacy and Implementation of a Virtually Delivered Parent-Focused Physical Literacy Intervention for Early Childhood.

Purpose Examine the efficacy of a virtually delivered, parent-focused physical literacy (PL) intervention for early childhood called PLAYshop and examine the level of and factors that influenced implementation. Methods A randomized controlled trial was conducted with 122 preschool-aged children (3-5 years) and their parents from western Canada. PLAYshop included a virtual workshop, educational and material resources, and follow-up support via an app with four booster lessons (1, 3, 5, 7 weeks post-workshop). Primary and secondary efficacy outcomes were measured at baseline and 2-month follow-up. Tertiary efficacy outcomes were also measured post-workshop (intervention group)/1-week post baseline questionnaire (control group). Tertiary implementation outcomes were measured via parental questionnaire and explored via parent and workshop leader interviews. Repeated measures Analysis of Covariance/Analysis of Variance and Generalized Estimating Equations were conducted. Results Intervention efficacy was not observed for children's PL (fundamental movement skills, motivation, enjoyment, confidence; primary outcome) or physical activity (PA; secondary outcome). Increases in other secondary and tertiary outcomes were observed in the intervention group, compared to the control group, including parent-child co-participation in PA (partial η
