Summary

WaznApp study is a 12-week randomized controlled trial aimed to evaluate the feasibility and preliminary efficacy of a self-directed behavioral weight-loss intervention targeting employees of an academic institution, using two popular consumer mobile applications for weight loss. The hypothesis is that individuals assigned to the app that provides interactive feedback and proactively motivates engagement in healthy behaviors (eating healthily and being more active) will be significantly better than those who receive the comparison condition (a simple calorie tracking app).

Interventions

COMBINATION_PRODUCT

Lark (JITAI)

Lark works as a just-in-time adaptive intervention (JITAI), providing interactive counseling through a chat-style interface. The app prompts users to self-monitor, set goals, review them, provides feedback, and social support.

COMBINATION_PRODUCT

MyFitnessPal (no JITAI)

MyFitnessPal (MFP) is a calorie counting app, which relies on user input for food tracking, but automatically tracks activity through the phone or through integrations with wearable devices. This app provides allows to set weight and caloric goals, review them and to receive feedback, but it has limited social support, a feature that is generally lacking in calorie-counting apps.
