简要总结
The investigators propose that healthy behaviors such as exercise could be increased through the use of tying devices - mechanisms that force a coupling of addictive activities (listening to the next chapter of a page-turner novel) with engagement in a healthy behavior (exercise).
详细描述
The study will test the effect of the following treatments as a means of increasing gym attendance over 10 weeks: 1. Participants receive access to 4 iTunes audio novels on their own iPods and prompted to listen to those novels only when exercising at the gym; 2: Participants receive 4 iTunes audio novels for a loaned iPod that they will only have access to at the gym; 3: Participants receive weekly emails asking them about their exercise.
