Attention to Incentives

October 7, 2015 updated by: University of Pennsylvania
In this experiment, the investigators will test the effectiveness of a two week 20x incentive multiplier on the investigators' corporate partner's users who are (a) not notified about the incentives in advance, and (b) notified about the incentives and their purpose. The investigators will test which group shows the largest boost in walking during the two week intervention and the most lasting behavior change.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Summary:

In this experiment, the investigators will test the effectiveness of a two week 20x incentive multiplier on AchieveMint users who are (a) not notified about the incentives in advance, and (b) notified about the incentives and their purpose. The investigators will test which group shows the largest boost in walking during the two week intervention and the most lasting behavior change.

Information:

The experimental conditions will vary the type and amount of information about incentives as follows:

  • Condition 1 - Uninformed: Users will receive 20x their usual incentives for two weeks, but will receive no emails informing them about the incentive program. (They may find out about incentives through the Achievemint platform.)
  • Condition 2 - Informed about Incentives and Purpose: Users will receive 20x their usual incentives for two weeks, and they will receive emails informing them about the incentives (one announcement before the incentives begin, and one email every two days reminding them about the overall incentive program). These emails will contain information about the incentives and the purpose of the incentives. Condition 2 will most closely resemble the "constant" condition in the previous experiment. Roughly the same initial announcement email will go out. The reminder emails sent every two days, however, will include more information about the overall program incentives to maximize the number of participants who learn about the incentive program at some point.

Mock-ups of the email announcements and reminders are shown below.

Incentives:

The investigators' incentives will consist of multipliers for points offered via Achievemint. Since the investigators found in the investigators' last experiment that the constant incentives were the most successful, the investigators will offer these incentives to all treated participants: 20x multipliers for 14 days.

Other details:

The other details of the experiment will be the same as the previous experiment:

  • Length of incentives: the investigators will offer incentives for 14 days.
  • Post-intervention observation: the investigators will observe all treatment groups for at least 30 days after the intervention.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Exclusion Criteria:

  • top 30 percentiles of active walkers
  • To the extent possible, given the investigators' target sample size, the investigators will exclude users who were enrolled in the investigators' previous experiment.

March 1, 2015

Primary Completion (Actual)
