Brief Summary

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.

Conditions

Nutrition, Healthy

Keywords

Food Literacy; Cooking Skills

Outcome Measures

Primary Outcomes (1)

• Food Waste Volume

  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).

  Change from Baseline to 10 weeks post-randomization

Study Arms (2)

Immediate Treatment Group

EXPERIMENTAL

Subjects first participate in 8 weekly cooking classes immediately after baseline data collection ends.

Behavioral: cooking and food skills intervention

Delayed intervention control group

NO INTERVENTION

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)

Interventions

cooking and food skills intervention BEHAVIORAL

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)

Limitations and Caveats

The primary outcome could not be analyzed for all participants. As a feasibility pilot, technical problems with measurement led to unreliable or uninterpretable data. In addition, there was a high amount of missing data. The small sample limits generalizability, and no conclusions about effectiveness can be drawn. Insights will guide methodological changes to reduce participant measurement burden and data collection errors.
