Evaluating Implementation and Impact 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.

The EQ-5D-5L consists of five dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). Participants are asked to indicate their level of functioning (from 1 "no problems" to 5 "extreme problems") on each of the five dimensions of the EQ-5D-5L. The EQ-5D-5 L describes 3125 distinct health states, with 11111 representing the best and 55555 the worst possible health states. The investigators apply the Canadian EQ-5D-5 L scoring algorithm to generate index scores, which ranged from - 0.148 for the worst (55555) to 0.949 for the best (11111) health states.

Health status will be assessed with the EQ-5D-5L visual analogue scale. Participants report on their health on a visual analogue scale from 0 (worst health) to 100 (best health).

Physical activity will be assessed by accelerometers (worn for 7 days) in a subset of participants in the Men on the Move study arm. The output variables are minutes per day of light, moderate and vigorous physical activity.

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.

Aspects of the larger social, political and economic environment that may influence delivery of the adapted CTM program will be assessed by interview.

DPOs perception that the adapted CTM program is agreeable or satisfactory 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).

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).

DPOs perception that the adapted CTM program can be successfully used within the organization 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).

Extent to which the adapted CTM program fits with the mission, priorities, and values of organizations or setting 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).

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

DPOs' norms, values, and basic assumptions around selected health outcomes (physical activity, mobility, social health) will be assessed by interview with DPO staff.

Perceptions among the DPOs that the adapted CTM program is relatively difficult to understand and use; number of different intervention components will be assessed by interview with DPO staff.

DPOs belief in their own capability to execute courses of action to achieve implementation goal will be assessed by interview with DPO staff.

The extent to which an organization is both willing and able to implement a particular innovation will be assessed using a modified version of the Readiness Diagnostic Scale. This scale evaluates three components of readiness: motivation (14 items), general capacity (24 items), and innovation capacity (12 items). Each item is scored on a 1-7 Likert scale with 1 being Strongly Disagree and 7 being Strongly Agree.

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.

Planned or purposeful changes to the delivery of the adapted CTM program by activity coaches will be assessed by survey (short answer responses; developed in house). Coaches will indicate if they made any adaptations to the program (yes/no) and to provide details of any adaptations such as why it needed to occur.

Planned or purposeful changes to the delivery of the adapted CTM program by activity coaches will be assessed by interview.
