Grocery Assistance Program Study for Families

November 9, 2020 updated by: University of Minnesota

Effects of Subsidies and Prohibitions on Household Nutrition in a Food Benefit Program

An experimental trial will be conducted whereby a Supplemental Nutrition Assistance Program (SNAP)-like food benefit program will be implemented in 240 SNAP eligible households. Baseline and follow up measures will include three 24-hour dietary recalls; household food purchase receipt collection; and household food security questions. The individual level measures will be collected from the adult most responsible for food shopping and a child in the household. After baseline measures are completed households will be randomized to one of three conditions: 1) restriction (not allowed to buy sugar sweetened beverages, sweet baked goods, or candies with food benefits); 2) restriction paired with an incentive (30% financial incentive on fruits and vegetables and restriction of purchase of sugar sweetened beverages, sweet baked goods, or candy with food benefits); or 3) control (no incentive or restrictions). Households in all conditions will be given a debit card that will have funds added monthly for a five month period. The dollar amount placed on the card monthly will be similar to the amount the household would receive if enrolled in SNAP. All participants will be instructed to use the debit card for food purchases only, and they'll be told they shouldn't use the card to purchase items currently non-eligible for purchase with SNAP benefits (e.g. alcohol, food from restaurants). Those in the restriction condition will also be told they cannot use the card to buy sugar sweetened beverages, sweet baked goods, or candies. They may purchase these foods using their own money, but not the debit card. Those in the restriction plus incentive condition will receive the instructions provided to the restriction group plus they will be told that they'll receive a 30% bonus for fruits and vegetables purchased using their debit card. Analyses will determine whether the nutritional quality of the diet at follow-up differs between experimental groups.

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.

Study Type

Study Type

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.
646

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

3 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

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.
No Intervention: Control
Experimental: Restricted
Behavioral: Restricted
Certain foods and beverages are not allowed to be purchased with food benefit dollars.
Experimental: Restriction plus Incentive
Behavioral: Restriction plus Incentive
Certain foods and beverages are not allowed to be purchased with food benefit dollars; 30% of the total dollars spent toward the purchase of certain foods result are added to their food benefit dollars.

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
Overall Nutritional Quality as measured by the Healthy Eating Index (HEI)-2015 score
Time Frame: 18 weeks
Overall Nutritional Quality obtained from average intake of three dietary recalls at both baseline and follow-up.
18 weeks

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.
