NCT ID: NCT02030119
Last Updated: 2017-12-02
Results Overview

Participant Flow
One participant randomly assigned to the gain-incentive group was later found to be ineligible due to previous enrollment in another physical activity study. One participant randomly assigned to the lottery-incentive group switched to a phone that was not eligible for use before the study began and therefore did not receive the intervention.

Control
The participant will receive either an email or text message (based on the participant's preference) stating whether the participant achieved their goal for the prior day.

Gain Framing
Participants will be told that they will earn money for each day they walk at least 7000 steps. Each participant will receive either an email or text message (based on the participant's preference) stating whether or not he/she achieved the goal for the prior day and can collect the earnings. Non-adherent participants will receive messages about how much they would have earned had they met their target step goal.

Daily Lottery
Each participant will be entered into a lottery daily, but participants will only be eligible to collect their winnings if they walked at least 7000 steps the day before. Participants will receive either an email or text message (based on the participant's preference) stating whether or not they won the lottery and if they met their target step goal. If both occur, the participant will be told how much money he or she won. Non-adherent participants will receive messages about how much they would have won had they met the target step goal.

Loss Framing
The participants will be told that their account has been credited a certain amount of money for the upcoming 30 days. However, for each day they do not meet their goal of at least 7000 steps, they will lose a small portion of that money. The participant will receive either an email or text message (based on the participant's preference) stating whether the participant achieved the goal for the prior day. Non-adherent participants will receive messages about how much the participant would have kept had they met the target step goal.
