About this study

Official title: Walking Intervention Through Texting Study: A Factorial Trial

The purpose of this study is to develop and evaluate adaptive goal setting and feedback interventions (Adaptive Interventions) to promote physical activity behaviors and compare it to static physical activity interventions (Static Interventions) using two levels of goal setting (Adaptive Goals vs. Static Goals) and two levels of reinforcement procedures (Praise/Rewards and No Praise/Rewards) in a 2 x 2 factorial randomized controlled trial. All four groups will receive the intervention via a semi-automated text message system developed by the investigators study team.

The primary aim of this study will be to:

  1. Evaluate whether the adaptive interventions result in greater change in physical activity (pedometer-measured steps/day) compared to the static Intervention groups. HYPOTHESES: Participants in the adaptive interventions will increase their steps/day more than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups. The secondary aims of this study will be to:
  2. Evaluate the effectiveness of the adaptive and static goal interventions in improving anthropometric, cardiovascular fitness, and cardiometabolic risk factors. HYPOTHESES: Participants in the adaptive interventions will show greater improvements in fitness, lean and fat body mass, and serum biomarkers than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups.
  3. to assess participants' satisfaction with the overall program.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Fitbit-measured Steps/Day and Moderate-to-vigorous Physical Activity Between Study Arms.

    Given this study used a 2 condition (adaptive vs. static goals) x 2 condition (immediate vs. delayed financial reinforcement) randomized factorial design we report main effects for each condition. Sample sizes for main effects will be 96 participants for each comparison (Adaptive vs. Static goals or Immediate vs. Delayed Reinforcement) as the other condition. Consistent with proper analyses of factorial designs, main effects for the goal setting conditions pool participants across reinforcement conditions, and main effects for reinforcement conditions pool participants across goal setting conditions.

    Measured: Daily for 4 months

Secondary outcomes (5)
  1. Change in Fitness (VO2max) Between Study Arms.

    Measured: Baseline and 4 months

  2. Changes in Body Mass Index and Body Composition Measured by Dual-energy X-Ray Absorptiometry (DEXA) Between Study Arms.

    Measured: Baseline and 4 months

  3. Changes to iAortic Pulse Wave Velocity Assessed With the SphymocorTM Between Study Arms.

    Measured: Baseline and 4 months

  4. Changes to Cardiovascular-disease (CVD) Risk and Inflammatory Markers (e.g. Glucose, Insulin, Lipids, Adhesion Molecules and Hemostatic Factors) Between Groups.

    Measured: Baseline and 4 months

  5. Changes to Self-reported Physical Activity Measured by the International Physical Activity Questionnaire (IPAQ).

    Measured: Baseline and 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Adaptive Goals, Reinforcement and Static Goals in people with Physical Activity and Behavior, run by Arizona State University 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 12 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 22 Sep 2021. 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?

Yes. Results are posted in the registry (first posted 29 Jul 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Fitbit-measured Steps/Day and Moderate-to-vigorous Physical Activity Between Study Arms. (time frame: Daily for 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02053259, which also lists 3 linked publications.

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?
