About this study

The aim of this study is to compare a Web-based system and a computer telephone system to determine their effectiveness in improving diet behaviors compared to each other and a control group.

Read the detailed description

The aim of this study is to compare a Web-based system (WEB-DIET) and a computer telephone system (TLC [Telephone Linked Communications]-DIET) for affecting dietary behavior change. These interventions will target the same dietary behaviors (consumption of fat and fruits and vegetables). The behavior change strategies and content will be derived from the same behavior change theory (the Transtheoretical Model [TTM]). A representative sample of ~1200 adults from a large urban area will be recruited through a list-assisted telephone list which will be bought by the University of Rhode Island so that subjects can be randomized into one of three groups: a Web-based system (WEB- DIET), a computer telephone system (TLC [Telephone Linked Communications]-DIET), or assessment only control. The study hypotheses, which will be evaluated both at the end of the 6-month intervention period and at the end of 18-month follow-up (post-baseline) observation period, are: 1. TLC-DIET> Control 2. WEB-DIET> Control 3. WEB-DIET> TLC-DIET.

What is being measured

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

  1. Change in diet from baseline to 6 months, 6 months to 18 months, and baseline to 18 months

    Self-reported diet questionnaire to measure fat and fruits/vegetables

    Measured: Baseline, 6 months, and 18 months

Secondary outcomes (2)
  1. Change in psychosocial variables from baseline to 6 months, 6 months to 18 months, and baseline to 18 months

    Additional theoretical variables, such as Stages of change, as measured by self-reported questionnaire

    Measured: Baseline, 6 months, and 18 months

  2. Change in diet variables from baseline to 6 months, 6 months to 18 months, and baseline to 18 months

    Additional diet variables, such as total calories, trans fat, and carotenoids, as measured by self-reported food frequency questionnaire

    Measured: Baseline, 6 months, and 18 months

Questions about this trial

What is this clinical trial studying?

A study testing TLC-Diet and WEB-Diet in people with Cardiovascular Disease, run by Boston Medical Center 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 6 inclusion and 3 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 May 2013. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 diet from baseline to 6 months, 6 months to 18 months, and baseline to 18 months (time frame: Baseline, 6 months, and 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 May 2013.
