简要总结
The objective of this project is to design a Behavioral Economics Based Online Lifestyle Balance Program that employs behavioral economics to engage and motivate adherence to an Internet-based program. The investigators compare the effects of two financial incentives on inducing weight loss: a direct financial incentive for weight loss and a financial incentive for health literacy.
详细描述
This project investigates whether participants in an online weight loss program can be induced to achieve weight loss using financial incentives. The study is a 3-arm randomized controlled trial (RCT) stratified by gender. The goal is to examine how overweight individuals respond to two different types of financial incentives. The first type of incentive, incentive for weight loss (IW), is a cash award of approximately $150 given for achieving 5% weight loss over 12 weeks. The second type of incentive, incentive for education (IE), is a $150 award for passing quizzes that test the participants' health literacy about weight loss and the techniques required for maintaining a healthy lifestyle. The investigators compare the effectiveness of IW to IE in promoting weight loss in overweight individuals and investigate whether the two incentives work equally well for men and women.

研究组 & 干预措施
Control
Participants are enrolled in a 12-week, self-administered online weight loss program. The program is delivered through 12 weekly sessions; each includes educational videos and a health literacy quiz. Each quiz contains 10 questions, and a quiz is considered "passed" when at least 7 questions are answered correctly. All participants are encouraged to follow the program, take the quizzes, and lose 5% of their baseline body weight by the end of the program.
No financial incentives are given for losing weight or passing quizzes.
Incentive for Education
Same 12-week, self-administered online weight loss program as in the Control arm.
Each participant is also given a $150 "Incentive for Education" for passing at least nine quizzes by the end of the program.
干预措施: Incentive for Education (Behavioral)
Incentive for Weight Loss
Same 12-week, self-administered online weight loss program as in the Control arm.
Each participant is also given a $150 "Incentive for Weight Loss" for losing 5% of their baseline body weight.
干预措施: Incentive for Weight Loss (Behavioral)
结局指标
主要结局
Weight Loss at the end of the weight loss program (at Week 13)
时间窗: At week 13 of the RCT.
Weight measured at the Week 13 weigh-in session. Weight measurements are taken by trained research assistants using digital scales.
次要结局
- Weight Loss at the end of the post-intervention period (Week 25)(At week 25 of the RCT.)
