Tying Devices as a Means of Increasing Exercise
Not Provided

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).

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.

Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Healthy
  • Behavioral: Control
    Receive weekly emails asking participants about their exercise and receive cash.
  • Behavioral: Suggested Tying Intervention
    Participants receive 4 iTunes audio novels for their own iPods to listen to only at the gym
  • Behavioral: Forced Tying Intervention
    Participants receive cash and also 4 iTunes audio novels for a loaned iPod accessible only at the gym to listen to only at the gym.
  • Experimental: Suggested Tying
    Receive same treatments as control group, but instead of receiving cash they receive 4 iTunes audio novels for their own iPods. Further, they are prompted to try to listen to those novels only when exercising at the gym in order to increase their attendance.
    Intervention: Behavioral: Suggested Tying Intervention
  • Experimental: Forced Tying
    Receives same treatment as the control group. However, in addition to receiving the cash, they also receive 4 iTunes audio novels for a loaned iPod that they will only have access to at the gym. They are told they may only listen to these novels only when at the gym in order to increase their attendance.
    Intervention: Behavioral: Forced Tying Intervention
  • Experimental: Control
    Control group of participants who do not receive any intervention but are weighed at the beginning and end of a 10 week period and receive weekly emails asking them about their exercise. They also receive the equivalent cash value of 4 iTunes audio novels
    Intervention: Behavioral: Control
