Brief Physical Activity Intervention for Older People With Multimorbidity

Study Overview
=================
Brief Summary
-----------------
Physical activity is an important determinant of health and well-being in older people. However, many older people do not achieve recommended physical activity levels and increasing older people's physical activity is challenging. This preliminary study will explore the effects of a brief physical activity intervention on physical activity and physical function in older people with multimorbidity. The findings will be used to inform the design of a subsequent adequately-powered randomised controlled trial.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Pilot randomised controlled trial
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>Brief physical activity intervention including an initial 45-minute physical activity consultation, telephone support after 2 weeks (approx. 15-minute call), and provision of a pedometer, written information, and a physical activity diary. Embedded behaviour change techniques will include goal setting, self-monitoring, building self-efficacy and social support, and overcoming barriers. | Behavioral: Brief physical activity intervention<br>* See arm/group descriptions<br>|
| No Intervention: Wait-list control<br>The control group will not receive any active or placebo intervention during the 4-week study period. They will also not receive any trial contacts during this period. They will however continue to be able to access their usual care from primary, secondary, community, and social services. After the final (4-week) follow-up assessment, this group will receive the full physical activity intervention. | |
