Music-visual Guided Physical Activity Promotion for Adults With Intellectual Disabilities

Summary

Objective: Although physical activity (PA) is cardiometabolic and psychologically beneficial to adults with intellectual disability (ID), its initiation and maintenance remain problematic. We examine the effects of a music-visual guided PA (MVgPA) intervention on the PA level, PA self-efficacy and interest as well as functional exercise capacity of adults with ID.

Hypothesis: Compared with usual care, MVgPA can significantly increase the participant's PA level and improve their PA self-efficacy and interest, and functional exercise capacity.

Design and participants: This cluster-randomized controlled trial will recruit 400 Chinese adults with mild to moderate ID from 20 residential care facilities.

Intervention: Based on the information-motivation-strategy model, MVgPA comprises a motivational and strategical preparatory session and ongoing support to residential service providers and a 12-week group-based staff-facilitated MVgPA (two 75-min session/week) for adults with ID. Outcome measurement PA level (primary outcome) will be measured by using an activity tracker. PA self-efficacy and interest will be measured by the Baseline Interview Questionnaire and visual analogue scale respectively. Functional exercise capacity will be measured by six-minute walk test. All outcomes will be measured at baseline, 13 and 25 weeks.

Data analysis: Intervention effects will be estimated using three-level mixed effects model.

Expected results: MVgPA will effectively enhance the PA levels of adults with ID. After intervention implementation, we expect that at least 50% of the residential care facilities allocated to the intervention group will demonstrate their willingness to continue to implement the MVgPA program (score 4 out of 6, 6 = most willing).

BEHAVIORAL

Music-visual guided physical activity (MVgPA)

The MVgPA adopts the information-motivation-strategy model to address the personal and environmental challenges in PA initiation and maintenance of adults with intellectual disability. To support the staff of residential care facilities in implementing 24 sessions of MVgPA in 12 weeks, the first six sessions will be led by the RA1 and co-facilitated by the staff, while the subsequent sessions will be conducted by the staff only. At week 6, another set of MVgPA will be implemented to increase the participant's interest; two sessions will be co-facilitated by RA1. At weeks 6 and 9, the RN and RA1 will hold a meeting with the staff of the residential care facilities to acknowledge the achievement of the staff and adults with ID, as well as to address any of their concerns related to the implementation of MVgPA, and to identify the facilitators and tackle barriers to the implementation of the MVgPA.

BEHAVIORAL

Usual care

As control group, residential care facilities will conduct their usual activities during the study period. A trained RA will record the activities conducted by the residential care facilities during the study period.
