Abstract
Client-choice food pantries provide greater choice in food item selection relative to traditional food banks. However, there is a potential for the clients to select a food bundle that is nutritionally deficient. With the prevalence of lower nutritional status among the clients due to poor dietary choices, it is important that food pantry stakeholders encourage clients to make healthier diet choices. More than 30% of the food pantry client households have at least one member diagnosed with diabetes and 58% have at least one member with hypertension. Our aim is to design a cost-effective and unobtrusive method (intervention) to encourage the choice of healthier food items without restricting choice and evaluate its effectiveness/efficacy.

Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Food pantry clients will be randomly assigned to the control or treatment group.
The treatment group will be nudged before they enter the pantry.
The control group will be provided no information.
Food items selected by the clients will be recorded after checkout
Experimental Design Details
For control group clients - Provide brief information to the clients about the study. - Obtain client consent for participating in the study. - Clients complete the survey. - Researchers record the food items selected by the clients at/after checkout. For treatment group clients - Provide brief information to the clients about the study and the nutritional ranking sheet. - Obtain client consent for participating in the study - Clients complete the survey and mark their selection of food items on the nutritional ranking sheet. (Clients are free to select any item from the pantry and are not restricted to their choice marked on the sheet. We will explain this to the clients.) - Researchers record the food items selected by the clients at/after checkout.
Randomization Method
Randomization done at run time at the place of intervention using a computer.
Randomization Unit
Individual clients will be randomized in treatment and control groups.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
1 food bank
Sample size: planned number of observations
Potential for recruiting 500-1000 food bank clients. This might change per the response rate.
Sample size (or number of clusters) by treatment arms
n/2 clients in control group and n/2 clients in treatment group. n = 500-1000.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
