NCT03566277

Brief Summary

The purpose of this study is to test whether deposit contracts, wherein individuals invest their own money with the study to serve as the incentive, with or without daily feedback about progress help individuals to increase step counts and more often meet a step goal compared to self-monitoring only.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Step counts

    Daily number of steps taken

    Throughout 16-week study, measured as the average of each two-week block (i.e., each time condition changes)

  • Goal attainment

    Proportion of days step goal was met

    Throughout 16-week study, measured as the average of each two-week block (i.e., each time condition changes)

Study Arms (1)

Single-arm trial

EXPERIMENTAL

All participants will undergo each of three conditions during the study.

Behavioral: Self-monitoringBehavioral: IncentivesBehavioral: Feedback

Interventions

Self-monitoringBEHAVIORAL

Participants will have access to a wrist-worn activity monitor and have a daily step goal

Single-arm trial
IncentivesBEHAVIORAL

Participants will have a deposit contract, wherein they will lose money if a goal is not reached, or double their money if a goal is reached

Single-arm trial
FeedbackBEHAVIORAL

Participants will receive text message feedback each day about progress towards their goal

Single-arm trial
