Evaluation of Choose to Move Replacement Ready (CTM-RR)

Obtained from post-program survey. Measures adherence to prescribed frequency, intensity, duration, and type of exercises performed, and attendance at CTM-RR group meetings.

Single-item physical activity questionnaire. Output measure is self-reported number of days engaging in ≥30 minutes of moderate-to-vigorous physical activity in the past week (range 0-7). Higher scores reflect a better outcome (i.e.

increased physical activity)

Number of individuals participating in CTM-RR programs will be obtained from program records

Obtained from evaluation records. Proportion of participants who consent to the evaluation who complete each assessment.

Obtained from post-program survey. Proportion of required intervention components (group meetings and one-on-one consultations) delivered by activity coaches.

Obtained from program records. Number of referral partners who refer participants to the program.

Planned or purposeful changes to the delivery of CTM-RR 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.

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

The 12-item Hip Disability and Osteoarthritis Outcome Score (HOOS-12) assesses patients' hip condition (pain, function, quality of life). Each item is scored on a scale of 0-10. The output variable is the average score of the 12-items (range 0-100); higher scores indicate worse hip problems.

The 12-item Knee Disability and Osteoarthritis Outcome Score (KOOS-12) assesses patients' knee condition (pain, function, quality of life). Each item is scored on a scale of 0-10. The output variable is the average score of the 12- items (range 0-100); higher scores indicate worse knee problems.

Single-item measure using a numerical rating scale: score (0-10) assesses the overall condition of the affected hip or knee joint. Higher scores indicate worse condition (severe symptoms).

The 8-item questionnaire assesses how certain an individual is that they can manage various aspects of their arthritis. Each item is scored on a scale of 1-10. The output variable is the average score of all 8-items (range 8-80); higher scores indicate more self-efficacy.

Pain Numerical Rating Scale (NRS): score (0-10) assesses pain intensity on average during the past week. Higher scores indicate worse pain intensity.

One item will assess participants' willingness to undergo hip or knee replacement surgery. The question asks: "What is your current willingness to undergo a [total hip replacement surgery or total knee replacement surgery]?" The response options are: definitely unwilling, probably unwilling, unsure, probably willing or definitely willing. Definitely unwilling, probably unwilling, unsure= No, and probably willing or definitely willing=Yes. The output variable is self-reported willingness to undergo surgery (yes/no).

The output variable is the total summed score of all 10 items (range 10-40); higher scores indicate greater self-efficacy for exercise.

Older adults will indicate which optional intervention components they engaged in (peer check-in, e-mail newsletter, hip and knee exercises; yes/no response options)
