Cognitive Distraction on Food Intake: Randomized Crossover Exploratory Study

September 1, 2019 updated by: Shelly Nickols-Richardson, University of Illinois at Urbana-Champaign

Effect of a Cognitive Distraction on Amount, Preference, and Memory of Food Consumed: a Randomized Crossover Exploratory Study

This study determined effects of a cognitive distraction on amount, preference, and memory of food consumed and perceptions of fullness, hunger, and enjoyment of food in a healthy young-adult population. A randomized controlled crossover study of 119 healthy adults, assigned to begin in either the distracted or control condition, was conducted.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Environmental distractions have been shown to affect eating patterns. Influences of food environments on consumption patterns and not simply food choices are becoming increasingly clear for their contributions to energy intake. Of particular interest is the presence of distraction. It has been postulated that when distracted, individuals are inclined to consumer more than when not distracted. However, how distraction and memory impact subsequent food choice and preference is less well known. A Rapid Visual Information Processing (RVIP) task was applied to distract individuals while eating; food intake and food behaviors were measured after RVIP distraction and compared to food intake and food behaviors without distraction in the same individuals.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

14 years to 21 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • able to read and speak English and willing to consume foods provided during the study

Exclusion Criteria:

  • adhering to any dietary restrictions or diets, having any food allergies, and/or having any chronic or metabolic diseases

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Distraction
Distraction during eating using the Rapid Visual Information Processing task as the distraction
Behavioral: Rapid Visual Information Processing task
A series of numbers appeared on a computer screen at a rate of one per minute. Each participant was required to identify any series of three consecutive odd or even numbers by hitting the space bar on the keyboard. The task lasted 15 minutes and included a 1-minute practice session before food being served. Participants were instructed to eat at will while completing the computer task.
Placebo Comparator: Control
No distraction during eating
Behavioral: None or Control condition
Participant were instructed to eat at will during a 15-minute duration.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Food intake
Time Frame: Up to 14 days
Consumption of food by number of food items eaten
Up to 14 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Snack intake
Time Frame: Up to 14 days
Consumption of snack choices by number of food items eaten
Up to 14 days
Memory of food intake
Time Frame: Up to 14 days
Recording of food that was eaten during the condition period by number of food items eaten
Up to 14 days
Fullness
