About this study
The objective of this study is to test whether the interventions offering short-term incentives (points redeemable for prizes), specific cued plans, and science-backed tips can help with creating enduring exercise habits. There are four (4) sub-studies within this protocol.
Read the detailed description
The four sub-studies are:
- Sweet spot Past studies have shown that steady routines associated with stable cues are a hallmark of successful habits. However, recent research has demonstrated that incentivizing an overly rigid routine (e.g., every workout must be at the same time each day) creates a less lasting exercise habit than incentivizing a flexible exercise routine (e.g., workouts can be at any time of day). In this study, the investigators examine whether offering higher rewards for exercise that occurs at a planned, routine time than for exercise at other times, but still offering some rewards for exercise outside of these planned moments, may improve over total flexibility for producing lasting habits.
- Falling off the Wagon (FOTW) In the long run, missing one workout won't make much difference to a person's overall health. Psychologically, however, missing a workout may lead people to feel they've already failed at meeting their fitness goals, zapping their motivation to exercise in the future. In this study, the investigators examine whether offering 50% larger incentive for exercise to people after they miss a planned workout leads to more sustained exercise habits than incentivizing all workouts equally.
- Think Twice Studies have shown that people tend to fall into the planning fallacy -- optimistically overestimating their performance in some future activity. In this study, the investigators examine whether people who the investigators taught about the planning fallacy would make more realistic exercise plans and adhere to those plans better.
- Weekly vs. Daily Routines (WDR)
This study will examine whether incentivizing people to create a daily routine that is consistent every day for a month or a weekly routine that is consistent every week for a month helps people build a more lasting exercise habit. In the daily routines condition, participants will be required to schedule workouts (and associated text reminders) at the same time of day on every weekday, and the same time of day on each weekend throughout our four week treatment period. In the weekly routines condition, participants will be allowed to schedule workouts (and associated text reminders) at different times on different days of the week, but their schedule must be the same for each of the four weeks of our four week treatment period.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The objective of this study is to test whether the interventions offering short-term incentives (points redeemable for prizes), specific cued plans, and science-backed tips can help with creating enduring exercise habits. There are four (4) sub-studies within this protocol.
Detailed description
The four sub-studies are:
- Sweet spot Past studies have shown that steady routines associated with stable cues are a hallmark of successful habits. However, recent research has demonstrated that incentivizing an overly rigid routine (e.g., every workout must be at the same time each day) creates a less lasting exercise habit than incentivizing a flexible exercise routine (e.g., workouts can be at any time of day). In this study, the investigators examine whether offering higher rewards for exercise that occurs at a planned, routine time than for exercise at other times, but still offering some rewards for exercise outside of these planned moments, may improve over total flexibility for producing lasting habits.
- Falling off the Wagon (FOTW) In the long run, missing one workout won't make much difference to a person's overall health. Psychologically, however, missing a workout may lead people to feel they've already failed at meeting their fitness goals, zapping their motivation to exercise in the future. In this study, the investigators examine whether offering 50% larger incentive for exercise to people after they miss a planned workout leads to more sustained exercise habits than incentivizing all workouts equally.
- Think Twice Studies have shown that people tend to fall into the planning fallacy -- optimistically overestimating their performance in some future activity. In this study, the investigators examine whether people who the investigators taught about the planning fallacy would make more realistic exercise plans and adhere to those plans better.
- Weekly vs. Daily Routines (WDR)
This study will examine whether incentivizing people to create a daily routine that is consistent every day for a month or a weekly routine that is consistent every week for a month helps people build a more lasting exercise habit. In the daily routines condition, participants will be required to schedule workouts (and associated text reminders) at the same time of day on every weekday, and the same time of day on each weekend throughout our four week treatment period. In the weekly routines condition, participants will be allowed to schedule workouts (and associated text reminders) at different times on different days of the week, but their schedule must be the same for each of the four weeks of our four week treatment period.

Questions about this trial
What is this clinical trial studying?
A study testing Sweet Spot: Flexible high incentive condition, Sweet Spot: Flexible low incentive condition and Sweet Spot: Rigid high incentive condition in people with Healthy, run by University of Pennsylvania at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Each participant's number of gym visits per week (time frame: During the 4 intervention weeks). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2020.
