简要总结
The goal of this feasibility study is to determine the adherence, acceptability, and usability of the behavioral intervention of a mobile AI application and its effects on food choices and diet quality. A secondary goal is to assess whether the app's accuracy or feasibility differs by food security status. Study participants are UC Davis students aged 18-24 years. The main question it aims to answer is:
- Does the gamified app version that delivers behavioral nudges have a higher adherence and acceptability rate, and does this translate to better dietary behaviors?
Participants will use either the intervention app (dietary assessment + gamification) or the control app (non-gamified, dietary assessment only) for six weeks to record all their food intake. Diet quality will be assessed at baseline and endline, and a Likert scale acceptability questionnaire will be administered at endline.

研究组 & 干预措施
Control group- Limited app version, dietary assessment only
Participants will be randomized at enrollment to the control group, which will receive a "limited" app version that only provides a daily report of caloric and nutrient intake, without delivering behavioral nudges.
干预措施: Limited app version for dietary assessment only (Other)
Intervention group- Gamified app version; dietary assessment + gamification
Participants will be randomly assigned at enrollment to the intervention group, which will receive a gamified app that delivers behavioral nudges and provides a daily report of caloric and nutrient intake.
干预措施: A mobile application that uses AI to deliver behavioral nudges that encourage healthy food choices. (Other)
结局指标
主要结局
App acceptability by version assigned to participants
时间窗: Measured at endline: at the end of the 6 week period
Acceptability will be assessed using a structured questionnaire based on a Likert scale from 1 (strongly agree) to 5 (strongly disagree) administered at the end of the study period.
App's usability by version assigned to participants
时间窗: Measured at endline: at the end of the 6 week period
Focus group discussions will be conducted with a select group of participants to assess usability (i.e. facilitators and barriers to app usage) at the end of the study period.
App adherence rates by version assigned to participants
时间窗: Assessed at midline (3 weeks) and endline (6 weeks)
App usage adherence will be evaluated based on analytics data, with a 70% usage threshold defined for both the midline and endline assessments.
次要结局
- Diet quality assessment by app version, measured using Healthy Eating Index scores at baseline and endline.(From enrollment till study completion at 6 weeks)
- App usability by food security status assessed using the USDA 10-item food security survey module(Food security assessed at baseline)
- App adherence rates by food security status assessed using the USDA 10-item food security survey module(Food security assessed at baseline)
- App acceptability by food security status assessed using the USDA 10-item food security survey module(Food security assessed at baseline)
