Individual Incentives - Arm 1
This arm receives diabetes education + goal setting + individual rewards Diabetes education: Participants interact with a diabetes educator (DE), every two weeks. Goal setting: Goals for weight loss and change in levels of HbA1c Individual Reward: The cash reward is given to the patient with diabetes.
Mixed Incentives (Altruism) - Arm 2 Patients
This arm receives diabetes education + goal setting + companion support + individual rewards Diabetes education: Participants interact with a diabetes educator (DE), every two weeks. Goal setting: Goals for weight loss and change in levels of HbA1c Companion Support: Patient has a companion/team support partner to help him/her in achieving goals. Individual Reward: The cash reward is given to the patient with diabetes.
Mixed Incentives (Altruism) - Arm 2 Companions
The companion support help the partner to achieve goals. The cash reward is given to the patient with diabetes and not to the companion.
Mixed Incentives (Cooperation) - Arm 3 Patients
This arm receives diabetes education + goal setting + companion support + shared rewards Diabetes education: Participants interact with a diabetes educator (DE), every two weeks. Goal setting: Goals for weight loss and change in levels of HbA1c Companion Support: Patient has a companion/team support partner to help him/her in achieving goals. Shared Reward: Patients with diabetes and their companion support will each receive 50% of the cash reward.
Mixed Incentives (Cooperation) - Arm 3 Companions
The companion support help the partner to achieve goals. Patients with diabetes and their companion support will each receive 50% of the cash reward.

PRIMARY outcome

Timeframe: Baseline and 3 months

Population: Some participants had data about weight but not about glycated hemoglobin and for that reason the number of participants in this table are different from the table that show the results of weight.
