Mobile Regulation of Craving Training (mROC-T) to Improve Dietary Intake in Rural Adolescent Girls

Sponsor

University of Wyoming

Enrollment

150 participants

Start Date

Feb 1, 2025

Study Type

INTERVENTIONAL

Conditions

Diet Modification Obesity and Type 2 Diabetes

Summary

The goal of this clinical trial is to test if a regulation of craving training intervention in the form of a mobile phone app can increase fruit and vegetable intake in adolescent girls ages 14-18 years of age. The main questions it aims to answer are: 1. What is the effect of a mobile app version of the regulation of craving training intervention on healthy eating index scores over one year? 2. What is the effect of a mobile app version of the regulation of craving training intervention on body mass index, waist circumference, and blood glucose over one year? Researchers will compare the active regulation of craving training arm to a control fun food fact arm to see if the regulation of craving training improves HEI scores, BMI, and blood glucose over a year. Participants will be asked to play the regulation of craving training mobile app twice a week for a year.

Interventions

BEHAVIORALRegulation of craving training

Participants randomized into the active mROC-T intervention (mROC-T+ or mROC-Tc) will: 1. Read a brief essay about either the social justice benefits of eating healthy foods (POSITIVE, mROCT+) or critical of social justice aspects of unhealthy foods (CRITICAL, mROC-Tc). 2. Participants complete six free-response questions to ensure that they understood the essays. 3\. Participants are instructed to use the information from the essay. They are shown a cue matching the essay they read either: "Think Positive" or "Think Critically". 4\. They are shown an image of a healthy food (no added sugar and \< 2g/serving saturated fat) OR an image of an unhealthy food (contain added sugar and/or \>4.5g/serving saturated fat). 5. Finally, the participant is asked to rate how strong their craving is for the pictured food. The participant indicates their craving on a VAS from 1 (No craving at all) to 5 (Very high craving)
