Study summary

Information about Americans food choices and opinions helps researchers and law makers to develop policies and programs to promote health. For this reason, it is important to be able to collect good quality information about how people think about food. This project will compare different ways of collecting information about food from adults.

Read the detailed description

Objectives:

-To compare different ways of collecting information about food choices and opinions from adults.

Eligibility:

  • Individuals between the ages of 20 and 70, recruited from a database of volunteers who wish to participate in research studies.
  • Volunteers must have high-speed Internet access.
  • Individuals who have previously been involved in a research study will be excluded.

Design:

-Participants will come to a research study center for three consecutive meals (approximately 45 minutes per meal). On the following day, participants will return to the study center for an interview about their food choices and opinions (approximately 45 minutes).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 3, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
