Brief summary
The investigators will conduct a randomized controlled trial to test financial incentive programs (versus control) to promote physical activity among 330 adults who have a YMCA membership. Participants will have the opportunity to earn up to $100 or $200 (depending on the condition they are assigned to) for attending at least 50 sessions at the YMCA over 6 months. Participants will have two 6-month windows during which they will have the opportunity to earn the incentive. In addition to the incentives, participants will complete research assessments every 3 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Number of YMCA visits | Baseline, 6 months, 12 months, 24 months | Number of sessions (max 1 per day) a person signs into the YMCA |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Accelerometry | Measured at baseline, and months 3, 6, 9, and 12. | Minutes of physical activity weighted by intensity, expressed in metabolic equivalent (MET) minutes per week as determined by accelerometers (Actigraph \[model wGT3x-BT\]) worn during one-week periods. |
| Change in Self-report physical activity (Godin) | Measured at baseline, and months 3, 6, 9, and 12. | Self-reported minutes of leisure time physical activity (inside and outside the YMCA) per week weighted by intensity |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change in Capability Questionnaire | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's physical and psychological capability to do regular aerobic physical activity with scores ranging from 1-7, and higher scores indicating more capability for physical activity. |
| Change in Exercise Facility Use Questionnaire | Measured at baseline, and months 3, 6, 9, and 12. | Measures access and membership to fitness facilities. |
| Change in Physical Activity Hedonic/Reflective Motivation | Measured at baseline, and months 3, 6, 9, and 12. | Measures the extent to which a person's motivation for physical activity is rooted in reflective and/or hedonic processes. There are two subscales. The hedonic subscale ranges from 0-10, with higher scores indicating more hedonic motivation for physical activity. The reflective subscale ranges from 0-10 with higher scores indicating more reflective motivation for physical activity. |
| Change in Subjective Social Status | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's perception of their subjective social status |
| Change in Reward Responsiveness | Measured at baseline, and months 3, 6, 9, and 12. | Measures the extent to which a person is responsive to external rewards |
| Change in Self-Reported Habit of Physical Activity Questionnaire | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's habits regarding exercise, with a minimum value of 1 and a maximum value of 7, higher scores indicate a stronger habit. |
| Change in Delay Discounting | Measured at baseline, and months 3, 6, 9, and 12. | Measures the extent to which a person discounts future rewards and prioritizes immediate rewards |
| Change in Loss Aversion | Measured at baseline, and months 3, 6, 9, and 12. | Measures the extent to which a person chooses actions in an attempt to avoid experiencing losses |
| Change in Overall Health (SF-12 Survey) | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's perception of their overall health and quality of life, scores range from 1-5 with higher scores indicating poorer health outcomes. |
| Change in Quality of Life and Health Status (EQ-5D-5L) | Measured at baseline, and months 3, 6, 9, and 12. | The EQ-5D-5L comprises a short descriptive system questionnaire and a visual analogue scale (EQ VAS) that are cognitively undemanding, taking only a few minutes to complete. The questionnaire provides a simple descriptive profile of a respondent's health state. The EQ VAS provides an alternative way to elicit an individual's rating of their own overall current health. When the descriptive system profile is linked to a 'value set', a single summary index value for health status is derived that can be used in economic evaluations of health-care interventions. A value set provides values (weights) for each health state description according to the preferences of the general population of a country/region. Value sets for the EQ-5D-5L and 3L versions are available in a large and growing number of countries. |
| Change in Absenteeism and Presenteeism | Measured at baseline, and months 3, 6, 9, and 12. | Measures the amount of time a person worked and was expected to work in the past 7-28 days; and their perceived job performance when at work |
| Change in Consideration of Future Consequences | Measured at baseline, and months 3, 6, 9, and 12. | Measures the extent to which a person considers the future (delayed) consequences of their actions |
| Change in Anticipated Regret Questionnaire | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's anticipated feelings of remorse if they do not do exercise, or achieve the incentives, on a scale from 1-11, with higher scores indicating more anticipated regret. |
| Change in Opportunity Questionnaire | Measured at baseline, and months 3, 6, 9, and 12. | Measures a person's opportunity to do regular aerobic physical activity, with scores ranging from 1-7, and higher scores indicating more opportunity for physical activity. |
