Conditions
Brief summary
The purpose of this study is to conduct a pilot randomized controlled trial, to determine whether providing financial incentives for meeting daily step goals (a) increases the daily step counts of participants, (b) increases compliance with the overall program (including diet recommendations), and (c) increases weight loss.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Daily Step Count | Change from week 1 to week 12 | Change in steps/day from week 1 to week 12. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Program Compliance | Change from week 1 to week 12 | Compliance with the physical activity prescription, means meeting or exceeding the step goal for that day. Participants' compliance was assessed by totaling the number of days they met their step goal and dividing it by the total number of days of the intervention. Thus, providing investigators the percentage of days that each participant complied with their physical activity prescription. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Weight Loss | Change from week 1 to week 12. There will also be measures taken 3 months following week 12 | Change in weight, waist circumference, and hip circumference from week 1 to week 12. There will also be measures taken 3 months following week 12. This will be defined as the follow-up data. |
