Evaluating Impact and Implementation of Choose to Move (Phase 4)

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 Mobility Assessment Tool-Short Form (MAT-sf) will be used to assess mobility. MAT-sf is a validated, short form video-animated tool to assess participant self-perception of mobility. Only participants with an internet connection are able to complete this measure. The output variable is a self-perception of mobility score (range 23.45-67.61) where a higher score indicates greater perceived mobility.

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 three-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 0-15); 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 five-item questionnaire will be used to assess change in sitting time (hours and minutes) each day in the following domains: (a) while travelling to and from places (e.g., work, shops); (b) while at work; (c) while watching television; (d) while using a computer at home; and (e) at leisure not including watching television (e.g., visiting friends, movies, eating out) on a weekday and a weekend day. The output variables are sitting hours per day across 5 domains.

A single item will be used to assess screen time. The output variable is hours of screen time per day.

Health status will be assessed using the EQ-5D-5L. Participants report on mobility, self-care, usual activities, pain/discomfort and anxiety/depression on a scale from 1-5 (level of perceived problems) for each item. Responses are used to create a 5-digit number which will be used descriptively (11111 indicates no problems on any of the five dimensions whereas 55555 indicates extreme problems on all five dimensions).

Health status (EQ-5D-5L Level Sum Score) will be assessed with the EQ-5D-5L. Participants report on mobility, self-care, usual activities, pain/discomfort and anxiety/depression on a scale from 1-5 (level of perceived problems) for each item. The Level Sum Score uses the 5-digit profile to create a numeric score, with scores ranging from 5-25 (lower levels indicate lower levels of perceived problems).

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).

The number of participants engaged in the intervention will be obtained from program records.

The number of organizations and activity coaches delivering the intervention will be obtained from program records.

The amount of intervention delivered will be assessed via survey (designed in house). Lower scores indicate that a lower dose of the intervention was delivered than planned.

Fidelity to planned delivery will be assessed via survey (designed in house). Higher scores indicate better adherence to planned delivery.

Fidelity to planned delivery will be assessed via interview/focus group.

Program satisfaction will be assessed via participant survey (designed in house). Higher scores indicate higher participant satisfaction with the intervention.

Program satisfaction will be assessed via interview.

Adaptation of the intervention and its delivery will be assessed via survey (designed in house).

Adaptation of the intervention and its delivery will be assessed via interview/focus groups.

Contextual factors influencing implementation (community level factors, provider characteristics, characteristics of the innovation, the prevention delivery system, organizational capacity and the prevention support system) will be assessed via survey (designed in house).

Contextual factors influencing implementation (community level factors, provider characteristics, characteristics of the innovation, the prevention delivery system, organizational capacity and the prevention support system) will be assessed via interviews/focus groups.

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

Organizational readiness (OR) will be assessed via survey (Organizational Readiness Rubric; ORR). The ORR comprises 14 items, each scored from 1-5. Higher mean scores indicate greater organizational readiness.

Organizational readiness (OR) will be assessed via survey (Readiness for Organizational Change Scale; ROCS). ROCS includes 25 items, each scored on a 5-point scale (1= strongly disagree to 5=strongly agree). Higher mean scores indicate greater organizational readiness for change.

Organizational readiness (OR) will be assessed via interview.
