Parent and organisational views on the TransformUs school-delivered physical activity program for children and adolescents with disability

Background: TransformUs is an efficacious school-delivered physical activity program. Its appropriateness for children and adolescents with disability remains unexplored. This study aimed to explore the views of parents and key organisations to identify factors influencing the successful implementation of TransformUs for children and adolescents with disability. Methods: Ten parents and nine key organisation representatives participated in 30-minute one-on-one online interviews, addressing individual-level experiences (parents) and broader system-/organisational-level perspectives (key organisations) relating to the different TransformUs strategies. Interview questions aligned with an established implementation outcomes framework, to assess intervention acceptability, adoption, appropriateness, feasibility, fidelity, implementation cost, penetration, and sustainability. Interviews were audio-recorded, transcribed, and thematically analysed. Results: Of the 19 interviewees (n=10 parents; n=11 female), 63% were aged 40–59 years. Facilitators for implementing TransformUs with children and adolescents with disability included (i) ease of delivery for acceptability; (ii) youth with disability’s perceptions/interest in physical activity for adoption; (iii) tailored resources/equipment for the specific needs of different disability types for appropriateness; (iv) flexible implementation strategies for increased fidelity; and, (v) a shift in the school-culture towards favouring physical activity opportunities for increased feasibility and sustainability. No themes related to implementation cost or penetration. Conclusion: Successful implementation of TransformUs for children and adolescents with disability may require collaboration with parents and key organisations, tailored and easy-to-use strategies, and whole-of-school practice. The results inform the development of inclusive adaptations of TransformUs (i.e., TransformUs All Abilities) and may support the development of other programs with similar scope.
