Evaluating Implementation and Impact of Provincial Scale-up of the Adapted Choose to Move (CTM) Program

The single item physical activity questionnaire will be used to measure physical activity. Output variable is self-reported number of days/week ≥30 min physical activity in the past week (range 0-7).

Two items will assess participants' ability to walk a quarter of a mile and up 10 steps. The output variable is self- reported presence of mobility-disability (no/any difficulty walking 400m or climbing one flight of stairs).

The Physical Functioning Subscale of the SF-36 will be used to assess the physical function aspect of mobility. The measure asks participants to rate if their health limits them in performing 10 different activities. The output variable is an average score (range 0-100) of physical functioning, where a higher score indicates a more favourable health state.

The three-item loneliness scale will be used to assess loneliness. Participants rate three aspects of loneliness. The output variable is loneliness score (range 3-9); lower scores indicate lower levels of loneliness.

A four-item questionnaire adapted from two questions on social contact frequency will be used to assess social isolation. The output variable is social isolation score (range 0-20); higher scores indicate lower levels of social isolation.

A six-item questionnaire will be used to assess social network. The output variable is an equally weighted sum (range 0-30) where higher scores indicate more social engagement.

A single item will be used to assess sense of belonging as an indicator of social connectedness. The output variable is sense of belonging score (range 1-4) where lower scores indicate a stronger sense of belonging.

A single item will be used to assess frequency (days/week) of physical activity that strengthens bone and/or muscle.

A single item will be used to assess frequency (days/week) of physical activity that improve balance.

Number of organizations and older adults participating in adapted CTM programs will be obtained from program records.

The neighbourhood characteristics of the regions where CTM programs were delivered will be determined using the Canadian Social Environment Topology (CanSET) tool.

Number of activity coaches trained to deliver the CTM program will be obtained from program records.

Number of group meetings (0-8) delivered by activity coaches will be assessed by survey (developed in house).

Fidelity to planned delivery will be assessed via survey (designed in house) for activity coaches and older adult participants. Higher scores (1-5 Likert scale) indicate better adherence to planned delivery.

Fidelity to planned delivery will be assessed via interview with activity coaches and older adult participants.

Program satisfaction will be assessed via participant (older adults) survey (designed in house). Higher scores (1-5 Likert scale) indicate higher participant satisfaction with the intervention.

Program satisfaction will be assessed via interview with older adult CTM participants.

Program delivery costs will be recorded using a cost capture template developed in house.

Extent to which the adapted CTM program can be adapted, tailored, refined, or reinvented to meet local needs will be assessed by survey (4 items each on a 1-5 Likert scale with 1 being completely disagree and 5 being completely agree; developed in house).
