Trial summary

This is a NCI funded study which will develop and evaluate a cell phone application (mDIET) that can be used as an assessment and intervention tool to improve dietary behaviors and thus reduce weight in overweight and moderately obese (BMI 25-34.9) men and women ages 25-55.

About this study

Official title: Ecological Momentary Intervention of Diet Via Mobile Technology

This is a NCI funded study which will develop and evaluate a cell phone application (mDIET) that can be used as an assessment and intervention tool to improve dietary behaviors and thus reduce weight in overweight and moderately obese (BMI 25-34.9) men and women ages 25-55.

Read the detailed description

This research will develop a technologically advanced system for monitoring and intervening on diet behaviors (e.g., food intake, weight). Interventions aimed at dietary change are missing a comparable, portable tool. Mobile technologies can help fill this gap by providing portable connectivity to expert systems that create specific tailored diet goals based on participant profiles. The expert system can 'push' intervention messages throughout the day during critical point-of-decision moments to aid in decision making among users. The portable device can 'pull' information through prompts and easy-to-use recording. This ecological momentary assessment + ecological momentary intervention format may further encourage healthy behaviors by prompting at critical decision points to improve dietary behaviors.

What is being measured

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

  1. Mean Weight (kg)

    Measured: 4 months

Secondary outcomes (2)
  1. Program Satisfaction

    Participants reported a 2 if they liked the program, 1 if they felt neutral about the program, and 0 if they did not like program. Higher scores reflect greater satisfaction.

    Measured: 4 months

  2. Compliance With Food Monitoring Activities

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Printed Material, Weekly Weighing and Cell phone will serve as a self monitoring device in people with Overweight, run by University of California, San Diego 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 9 inclusion and 4 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 30 Apr 2019. 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 4 Sep 2013). 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?

Mean Weight (kg) (time frame: 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 NCT00415870, which also lists 2 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2019; AzTrials last refreshed its copy on 7 Nov 2026.
