GamerFit-ASD demonstration pilot: evaluation of the feasibility and preliminary efficacy of an evidence-based exergaming and telehealth coaching intervention for autistic youth

Objectives: We piloted GamerFit-ASD, a theory- and evidence-based exergaming and telehealth coaching intervention, specifically adapted for autistic youth, for feasibility, acceptability, accessibility, and preliminary efficacy. Methods: This 12-week single-arm demonstration pilot recruited youth ages 10–15 years; the intervention included wearing a Fitbit, following a 3-times/week exergaming program, and meeting weekly with a health coach. Accelerometry data were collected at baseline and week 12; paired t-tests were used to assess physical activity (PA) changes. Feasibility and engagement were assessed with process measures. Results: 23 participants with a parental report of autism spectrum disorder were enrolled (average age 11.6 years; 78% male-identified; 83% white; 17% with parent-reported intellectual disability). Coaching session attendance was 92%; on average, participants completed 67% of exergaming sessions/week, 78.5 min/week of exergaming, and 6645 steps/day. Most youth reported enjoying the exergames (72%) and intending to continue playing them (67%); 94% reported it was easy to learn the games; and 79% of parents reported it was easy to participate. Total PA increased on average by approximately one hour per week, but this change was not statistically significant (p = 0.35). Conclusions: GamerFit-ASD was feasible, acceptable, and accessible among these participants. Effectiveness should be evaluated via randomized controlled trial (RCT) with a larger, more diverse sample.
