About

The purpose of this study is to test the effectiveness of On the Move (OTM) in terms of improving mobility among 502 older adults in 44 senior community centers and to evaluate intervention fidelity, including adherence and competence, and the impact of organizational, instructor, and participant level factors on intervention fidelity.

Full description

The investigators will conduct a Hybrid I trial, blending effectiveness and implementation research aims to: test the effectiveness of OTM, evaluate intervention fidelity, and determine the extent intervention fidelity moderates intervention effectiveness. The investigators will evaluate the effects of OTM taught by community instructors for improving mobility among 502 older adults in 44 community centers using a cluster randomized design with a delayed intervention control arm. Intervention fidelity will be assessed by instructor self-report (intervention diaries) and observation (fidelity checklist). Organizational, instructor, and participant level factors which may impact fidelity will be assessed via standard instruments, focus groups and interviews.

Specific Aims are as follows:

Aim 1: Establish the effectiveness of OTM on improvements in walking ability and post-intervention persistence of benefits.

Rationale: OTM delivered by research staff is effective. Establishing the effectiveness of OTM delivered by community instructors is necessary before wide-scale implementation.

Hypothesis: Compared to a randomized control group followed for 12 weeks, the OTM group will have greater gains in gait speed (primary outcome) and self-reported mobility at 12 and 24 weeks of follow-up.

Aim 2: Assess intervention fidelity (measures of adherence and competence) and identify the impact of organizational, instructor, and participant level factors on intervention fidelity.

Rationale: To inform future implementation efforts, it is critical to measure intervention fidelity and to identify factors associated with fidelity.

Hypothesis: Organizational, instructor, and participant level factors will impact fidelity. For example, instructors who utilize greater facilitation strategies will have higher fidelity, poor organizational acceptance of the program will be related to lower fidelity, and fewer organizational resources will lead to lower fidelity.

Aim 3: Determine the extent to which intervention fidelity, measured by adherence and competence, moderates the effectiveness of OTM.

Rationale: Intervention fidelity may influence the effectiveness of OTM. Understanding the consequences of differing levels of intervention fidelity on effectiveness will inform future implementation efforts.

Hypothesis: Higher fidelity will be associated with greater mobility gains, and there may be critical fidelity thresholds.

502 participants in 2 patient groups

On the Move
Experimental group
Description:
On the Move group exercise program to improve walking. Delivered twice per week for 12 weeks.
Treatment:
Behavioral: On the Move group exercise
On the Move - Delayed
Other group
Description:
Individuals in this arm will be placed on a wait-list for 12 weeks and will receive no intervention during this time. At the end of the 12 weeks they will receive the On the Move group exercise program. This is a wait-list control group.
