What this study is about
This study will evaluate a digital nudge intervention, Healthy Options At Pantries (HOAP), in the online food pantries of three large charitable food organizations. The study will use a hybrid effectiveness-implementation design, meaning it will evaluate whether the intervention works and how it can best be rolled out in an online food pantry setting.
View original scientific description
This study will evaluate a digital nudge intervention, Healthy Options At Pantries (HOAP), in the online food pantries of three large charitable food organizations. The study will use a hybrid effectiveness-implementation design, meaning it will evaluate whether the intervention works and how it can best be rolled out in an online food pantry setting. Intervention effectiveness will be evaluated using an interrupted time series analysis to identify changes in how healthy foods ordered by shoppers are (primary outcome) by comparing food ordering data over time before and after HOAP is introduced. The study will also evaluate the possibility of collecting dietary and clinical outcomes in a small subgroup of online pantry shoppers over time comparing both in-person and at-home approaches.
Interventions
BEHAVIORAL
Behavioral economics-based Healthy Options At Pantries (HOAP) digital nudge intervention
Intervention will include behavioral digital nudges over a 6-month period to promote healthier food selection among online food pantry shoppers.
Primary outcome measures
Change in Healthfulness of Shopper Food Selection
Time frame: 6 months pre-intervention and 6 months post-intervention
The primary outcome is change in the healthfulness of shopper food selection over time, measured using the Charitable Food Network Index (CFNI). At each time point, food orders will be categorized into proportions of green, yellow, and orange items based on the Healthy Eating Research (HER) guidelines. These proportions will be combined into a composite CFNI score. CFNI scores range from 0 to 100, with higher scores indicating healthier overall food selections.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
