Pregnant individuals or those with terminal illnesses cannot join.Check my eligibility
What is being tested?
The study tests if group commitment contracts help people quit smoking and lose weight better than individual rewards or contracts. It's a randomized controlled trial, meaning participants are randomly assigned to different groups to compare outcomes.See study design
What are the potential side effects?
There may not be direct medical side effects from participating; however, there could be financial loss due to the nature of commitment contracts if goals aren't met. Stress or frustration might also occur as part of behavior change efforts.
