Nourish Pilot & CoDesign Study

January 23, 2026 updated by: Case Western Reserve University
The purpose of the research study is to learn more about the best ways to teach cooking and food skills to adults, and how cooking classes may help reduce one's stress and food waste, as well as improve their diet.

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

Currently, 12.8% of Americans experience food insecurity, and food insecurity is associated with elevated perceived stress. Food literacy is proficiency in food-related skills and knowledge, including food preparation and cooking skills, basic nutrition knowledge, and the ability to prevent food waste. Recent research conducted in Australia suggests that food literacy interventions are associated with improved food security. Traditionally food literacy interventions take a recipe-based approach to culinary nutrition and lack information about key components of food literacy, such as food storage and food waste reduction techniques. However, recent research by the PI contends that recipes may be difficult for food insecure individuals to implement at home, given the challenge of procuring ingredients, suggesting the need for a new approach. In addition, food insecure households face additional environmental challenges, such as owning fewer cooking utensils, compared to food secure households. Based on the Social Cognitive Theory, the Nourish intervention addresses these limitations by incorporating food waste reduction, food storage knowledge, and improvisational cooking skills (cooking with what you have on hand) into food literacy and culinary nutrition education, as well as providing key cooking utensils. Eventually, the study team plans to test the impact of the Nourish intervention on food literacy, perceived stress, diet quality and food security to determine if food literacy interventions can positively impact perceived stress, diet, and food security. The present pilot study will test the feasibility and acceptability of the Nourish intervention and corresponding evaluation, as well as provide participant feedback on the intervention.

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.
26

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Design Details

  • Primary Purpose: Health Services Research
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

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: Immediate Treatment Group
Subjects first participate in 8 weekly cooking classes immediately after baseline data collection ends.
Behavioral: cooking and food skills intervention
Participants will attend a weekly in-person class with brief instructional video clips, hands-on cooking and tasting experiences. Participants will work individually and as part of small groups during instructional sessions. At the end of each class, participants will receive a grocery bundle and a kitchen gadget that serves both as an incentive and implementation support to promote improved cooking frequency and confidence. Participants will be asked to post photos of what they made with their groceries to an instant messaging software (GroupMe application) and be encouraged to engage with fellow classmates on GroupMe to encourage social support of cooking. The intervention ends after the 8, weekly classes conclude (8 weeks total intervention time)
Other Names:
  • Nourish
No Intervention: Delayed intervention control group
Subjects receive no intervention for 9 weeks, serving as the control group. Once all data collection is complete, the delayed intervention control group will receive the intervention (8 weekly cooking classes)

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 Waste Volume
Time Frame: Change from Baseline to 10 weeks post-randomization
Food waste volume will be measured in grams using a study-provided food scale and waste log. Participants are asked to weigh discarded food and log the weight in a food waste tracking notebook for a period of 1 week prior to randomization at Baseline, and again for a period of 1 week at 10 weeks post-randomization. The outcome measure will use the difference in total volume of food waste between the two time points (post total food waste - pre total food waste).
