Researching Engagement With Educational Lifestyle Content

The goal of this study is to examine how different types of health messages affect people's self efficacy for healthy eating and diet quality. Eligible adult participants with overweight/obesity will be randomized into one of two groups: the intervention group, which will engage with audio-visual messages per week for four weeks, or the control group, which will not engage with any audio-visual messages but will receive written educational materials about healthy eating per week for four weeks.

Treatment and study plan

Nutrition Education

Behavioral

This intervention uses curated audio-visual messages through videos and films to engage participants in learning about healthy eating behaviors, followed by structured, brief discussions designed to reflect on the content and relate it to personal dietary habits. The intervention leverages narrative-based media to increase self-efficacy for healthy eating.

Control Group

Other

Educational materials about food and healthy in the form of handouts will be provided to participants to review.
