     Physical activity self-efficacy will be measured at Wave 3 with the 48-item physical activity self-efficacy scale [11].

     Responses to the six Likert-scale quantitative items intended to measure the transportation-related moderate sub-scale will be summed at Wave 3 to form a transportation-related moderate sub-scale score at Wave 3 with higher values representing greater physical activity self-efficacy (transportation-related moderate). The minimum score will be 0. The maximum score will be 24.

120. physical activity self-efficacy (domestic and gardening-related moderate sub-scale)

     Time frame: Week 11

     Physical activity self-efficacy will be measured at Wave 3 with the 48-item physical activity self-efficacy scale [11].

     Responses to the six Likert-scale quantitative items intended to measure the domestic and gardening-related moderate sub-scale will be summed at Wave 3 to form a domestic and gardening-related moderate sub-scale score at Wave 3 with higher values representing greater physical activity self-efficacy (domestic and gardening-related moderate). The minimum score will be 0. The maximum score will be 24.

121. physical activity self-efficacy (leisure-related moderate sub-scale)

     Time frame: Week 11

     Physical activity self-efficacy will be measured at Wave 3 with the 48-item physical activity self-efficacy scale [11].

     Responses to the six Likert-scale quantitative items intended to measure the leisure-related moderate sub-scale will be summed at Wave 3 to form a leisure-related moderate sub-scale score at Wave 3 with higher values representing greater physical activity self-efficacy (leisure-related moderate). The minimum score will be 0. The maximum score will be 24.

122. Self-efficacy to regulate physical activity

     Time frame: Week 11

     Self-efficacy to regulate physical activity will be measured at Wave 3 with the 13-item self-efficacy to regulate physical activity scale [11].

     Responses to the thirteen Likert-scale quantitative items will be summed at Wave 3 to form a a total self-efficacy to regulate physical activity score at Wave 3 with higher values representing greater self-efficacy to regulate physical activity. The minimum score will be 0. The maximum score will be 52.

123. physical activity (Fitbit Zip)

     Time frame: Week 12

     A commercial-grade (Fitbit Zip) accelerometer will be initialized and attached to an adjustable nylon belt to measure physical activity objectively at Wave 3. Average minutes-per-day of moderate to vigorous physical activity will be determined using the Fitbit application, which uses a proprietary algorithm to estimate fairly active minutes and very active minutes.

124. physical activity (Actigraph wGT3X-BT)

     Time frame: Week 12

     A research-grade (Actigraph wGT3X-BT) accelerometer will be initialized and attached to an adjustable nylon belt to measure physical activity objectively at Wave 3. Average minutes-per-day of moderate to vigorous physical activity will be calculated based on established cut points (e.g., > 1952 counts per minute).

125. self-reported physical activity

     Time frame: Week 12

     Self-reported physical activity will be measured at Wave 3 with the long form of the international physical activity questionnaire [9,10]. Average minutes-per-day of moderate to vigorous physical activity will be formed by dividing the sum of the minutes per day (across one week) of minutes-per-day of moderate to vigorous physical activity in the work, transportation, domestic and gardening, and leisure domains by 7 days.

126. feasibility of accelerometer-based assessment of physical activity (participation rate)

     Time frame: Week 12

     The feasibility of accelerometer-based assessment of physical activity will be assessed with participation rate at Wave 3. Participation rate at Wave 1 will be defined as the percentage of consented patients who provide usable data at Wave 3.

     Usable data will be defined as: (a) a log sheet with a valid start date is submitted, (b) a monitor is worn for at least 4 days (including one weekend day) with at least 10 hours of valid wear time per day, and (c) no evidence of monitor error (e.g., activity counts > 20,000 or lengthy strings of repeated activity counts).

127. feasibility of accelerometer-based assessment of physical activity (retention rate)

     Time frame: Week 12

     The feasibility of accelerometer-based assessment of physical activity will be assessed with retention rate at Wave 3. Retention rate at Wave 3 will be defined as the percentage of consented patients who provide usable data at Wave 1, Wave 2, and Wave 3.

     Usable data will be defined as: (a) a log sheet with a valid start date is submitted, (b) a monitor is worn for at least 4 days (including one weekend day) with at least 10 hours of valid wear time per day, and (c) no evidence of monitor error (e.g., activity counts > 20,000 or lengthy strings of repeated activity counts).

128. acceptability of accelerometer-based assessment of physical activity (quantitative)

     Time frame: Week 13

     The acceptability of accelerometer-based assessment of physical activity will be assessed at Wave 3 with a modified version of an unnamed questionnaire used in previous research [7,8]. The 11-item acceptability questionnaire used in this study consists of a mix of both Likert-scale quantitative (6) and open-ended qualitative (5) items.

     Responses to the six Likert-scale quantitative items will be summed at Wave 3 to form a total acceptability score at Wave 3 with higher values representing greater acceptability. The minimum total acceptability score at Wave 3 will be 6. The maximum total acceptability score at Wave 3 will be 23.

129. acceptability of accelerometer-based assessment of physical activity (qualitative)

     Time frame: Week 13

     The acceptability of accelerometer-based assessment of physical activity will be assessed at Wave 3 with a modified version of an unnamed questionnaire used in previous research [7,8]. The 11-item acceptability questionnaire used in this study consists of a mix of both Likert-scale quantitative (6) and open-ended qualitative (5) items.

     Responses to the five qualitative items will be content analyzed together at Wave 3 to find conceptual themes at Wave 3 with regard to the acceptability of accelerometer-based assessment of physical activity.
