Validation of Restaurant App (VRA)

July 15, 2025 updated by: University of Pennsylvania

Pilot Randomized Controlled Trial of Food Policies to Promote Healthier Choices at Restaurants

Unhealthy diets significantly contribute to preventable chronic diseases among older adults. To advance the investigator's understanding of policies needed to support healthy diets, the objectives are: 1) to develop and validate an online fast food restaurant ordering application; and 2) to conduct a feasibility study for a larger randomized, controlled trial that will test healthy food policies in restaurant settings.

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.

Detailed Description

To advance the investigator's understanding of policies needed to support healthy diets and nutrition security, the overall objectives are: 1) to develop and validate an online restaurant ordering application that will mimic a real fast-food restaurant; 2) to conduct a feasibility study for a larger randomized, controlled trial that will examine the extent to which healthy food policies like ultra-processed food and beverage taxes and warning labels as well as restrictions on checkout aisle marketing influence restaurant purchases. The development of this restaurant application will enable the investigator's to conduct rigorous experiments that can test policy changes to the online restaurant ordering environment. In the feasibility study, participants will be randomized to either: 1) control (no taxes, warning labels, or healthy checkout regulations on any products); or 2) a suite of healthy food policies (ultra-processed food and beverage taxes, front-of-pack nutrition labeling, and healthy check out regulations that restrict the promotion of ultra-processed products on the checkout page). The investigators propose recruiting 60 adults with low income who live in the Philadelphia, PA region. Participants will be recruited for a 3-week study. During week 1, they will be asked to make a purchase in person at a physical McDonald's location and text the research staff a picture of their receipt (a procedure that has have successfully used in the past). During weeks 2 and 3, they will be asked to shop once per week on the restaurant platform, which will be modeled after McDonald's online ordering site. Week 2 will be a baseline (control) week without interventions followed by Week 3, when the healthy food policy interventions will be introduced into the restaurant ordering interface. During each of the 3 weeks, participants will be given money to spend on their restaurant purchases. A restaurant delivery service (e.g., GrubHub) will be used to send participants the food they order. Participants will also complete a baseline and post-intervention survey. To begin to establish the validity of the online restaurant ordering app, investigators will examine the correlation between the total calories and sugars purchased as well as dollars spent when purchasing food in person vs. on the app. The rationale underlying the proposed research is based on the investigator's work showing that beverage taxes and warning labels greatly reduce SSB purchases. The research team's long-term goal is to understand the independent and combined effects of promising food policies to improve nutrition security and reduce nutrition-related diseases. The specific aims are:

Aim 1: To develop and validate an online restaurant ordering app that can be used to experimentally test the effects of food policies on restaurant purchases.

Aim 2: To conduct a pilot study on the feasibility of implementing healthy eating interventions and policies such as ultra-processed food and beverage taxes, warning labels, and checkout restrictions through the restaurant app.

Because the pilot study is a small-scale feasibility trial, it will generate descriptive statistics for outcomes, but they will not be formally analzyed.

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.

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.

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

Time Frame: Assessed at study completion, average of 3 weeks.
We will also assess the acceptability of the online restaurant (e.g., overall experience using the restaurant, ease of use) and realism of the restaurant (e.g., extent to which participants' selections are similar to usual purchases, extent to which it felt real).
Assessed at study completion, average of 3 weeks.
