Structuring Financial Incentives to Increase Physical Activity
2 ottobre 2019 aggiornato da: Prof Ho Teck Hua, National University of Singapore
The purpose of this study is to evaluate the effectiveness of different structures of long term financial incentives on increasing physical activity performed by subjects, as measured by the number of steps walked per day.
Investigators are interested in studying whether physical activity increases during an intervention period (with incentives) and a post-intervention period (with no incentives).

Descrizione dettagliata
The proposed study is a field experiment. Adults within the ages of 25 and 60 years of age, and with a body mass index of 22 or higher will be eligible to participate.
The study will consist of (1) a two-week baseline period, (2) a 36-week intervention period, and (3) a 12-week follow-up period.
At the beginning of the study, subjects will be given a wearable fitness device and their daily step count will be monitored for two weeks; this is the baseline period. After the two-week baseline period, the subjects will be randomly assigned to one of the five different conditions (Control, Gain, Loss, Gain Streak, or Loss Streak) and will be given the goal to increase their baseline step counts by 2,500 steps.
=====
HYPOTHESES -- Investigators expect the following:
- Loss Aversion: Subjects in the Loss treatment will achieve the goal on a greater number of days than subjects in the Gain treatment.
- Streak: Subjects in the Gain treatment will achieve the goal on a greater number of days than subjects in the Gain Streak treatment.
- Loss Streak: Subjects in the Loss treatment will achieve the goal on a greater number of days than subjects in the Loss Streak treatment. Whether subjects in the Loss Streak treatment will perform better or worse than subjects in the other two treatments will be investigated.
CONTRIBUTION -- Prior research has not examined the effect of a long term financial incentive (36 weeks) on individual behavior in achieving a goal. In this study, the investigators also examine two additional financial incentive structures: Gain Streak and Loss Streak. If the hypotheses are correct, the results have important implications for designing financial incentives to encourage good behavior and to encourage good habit formation across domains.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Nessun intervento: Control
Subjects in the Control treatment are not given any financial incentive to achieve the goal.
|
|
|
Sperimentale: Gain Treatment
Financial Incentive: Each subject in the Gain treatment will earn a certain amount of money for each day the goal is achieved.
The money earned will be added to a virtual account that the subject has, and will be paid to the subject at the end of the intervention period.
|
Giving different structures of long term (36 weeks) financial incentives to increase physical activity
|
|
Sperimentale: Loss Treatment
Financial Incentive: Each subject in the Loss treatment will be given a certain amount of money in his/her virtual account at the beginning of every week.
For each day that the subject does not achieve the goal, a small portion of that money will be deducted from the virtual account.
The balance that is left in the virtual account will be paid to the subject at the end of the intervention period.

|
|
Sperimentale: Gain Streak Treatment
Financial Incentive: Each subject in the Gain Streak treatment get an increasing amount of money added to his/her virtual account for every continuous day that they achieve the goal.
The maximum cumulative amount per week is same as in the other treatment conditions.
The payment is reset at the beginning of each week, or if the subject misses the goal on any day.
The money in the virtual account will be paid to the subject at the end of the intervention period.

|
|
Sperimentale: Loss Streak Treatment
Financial Incentive: Each subject in the Loss Streak treatment will be given a certain amount of money in his/her virtual account at the beginning of every week.
An increasing amount of money will be deducted for each consecutive day the subject does not achieve the goal.
The payment is reset at the beginning of each week, or when the subject achieves the goal (i.e., deductions are reset when the streak is broken).
The balance that is left in the virtual account will be paid to the subject at the end of the intervention period.
