experimental: Group A (low-value incentive, 6 months [24 weeks])
If the participant is assigned to Group A, they would receive $1.75 for each day that they meet their diabetes self-management goal. This equates to up to $49 every 4 weeks ($1.75 x 28 days = $49), or up to $294 over a period of 24 weeks. They would also receive $2.75 for each week that they meet their clinical outcome goal. This equates to up to $11 every 4 weeks ($2.75 x 4 weeks), or up to $66 over a period of 24 weeks. In total, they could earn up to $60 ($49 + $11) every 4 weeks, or up to $360 over a period of 24 weeks.
experimental: Group B (high-value incentive, 6 months [24 weeks])
If the participant is assigned to Group B, they would receive $3.50 for each day that they meet their diabetes self-management goal.

This equates to up to $22 every 4 weeks ($5.50 x 4 weeks), or up to $132 over a period of 24 weeks.
