Choose to Move: Impact and Implementation Evaluation of a Program to Enhance Older Adult Physical Activity, Mobility and Health

CTM is a 6 month, choice-based program for low active older adults being scaled-up in phases across British Columbia, Canada. Within CTM (phase 3), trained activity coaches support older adults in three ways. First, in a one-on-one consultation, activity coaches help participants to set goals and create action plans for physical activity tailored to each person's interests and abilities. Older adults can choose to participate in individual or group-based activities. Second, activity coaches facilitate a series of group meetings with small groups of participants. Finally, activity coaches regularly check in with participants to provide ongoing support. Activity coaches and recreation departments across BC are trained and provided with resources to deliver CTM.

Objectives:

1. To assess the impact (effectiveness) of CTM (phase 3) delivered at scale on the physical activity, mobility and social connectedness of older adults (Part I - Impact Evaluation)
2. To assess whether the program was implemented as planned (fidelity) and investigate factors that support or inhibit implementation at scale (Part II - Implementation Evaluation).

Study Design:

We use a hybrid type 2 effectiveness-implementation (Curran et al 2012) pre-post study design to evaluate CTM. We use mixed-methods (quantitative and qualitative) and collect data at 0 (baseline), 3 (mid-intervention), 6 (post-intervention) and 18 (12-months post-intervention) months to assess effectiveness and implementation of CTM.
