Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to compare the effect of two strategies to increase MVPA in adolescents with intellectual and developmental disabilities (IDD): a single level intervention delivered to the adolescent only, and a multi-level intervention delivered to both the adolescent and a parent .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will study adolescents with mild to moderate IDD. Each participant will have 1 designated parent who supports the participant during the physical activity (PA) intervention and in the adolescent and parent arm does the physical activity with the participant. Approximately 29 participants/yr. over 4 yrs. will be randomized in a 1:1 allocation to a remote group-based program of MVPA delivered to the adolescent (AO) or a multi-level intervention delivered to both the adolescent and a parent (A+P). Both interventions will be 12 mos. (6 mos. active intervention, 6 mos. maintenance intervention) with a 6 mos. no-contact follow-up targeted to increase MVPA to the recommended 60 min/d. Both intervention will include real-time MVPA sessions delivered to groups of 5-7 adolescents in their homes using video conferencing software (ZoomTM) with homework assignments designed to increase MVPA on the non-group session days. Parents of adolescents in the A+P group will be asked to participate in the group video MVPA sessions and homework activity, and to attend sessions (0-6 mos. 2 session/mo.; 7-12 mos. 1 session/mo.) with their adolescent and the health coach designed to educate/support parents regarding the role of MVPA in health and function and strategies for increasing MVPA and decreasing sedentary time in both their adolescent and themselves. All participants will monitor their daily PA using a Fitbit wireless activity tracker.
