Self-Monitoring Assessment in Real Time (2-SMART)

Self-Monitoring Assessment in Real Time: 2-SMART

The purpose of the study is to test the effectiveness of two different methods of mobile dietary self-monitoring for weight loss. Both of these interventions will provide weight loss information through twice weekly audio podcasts. In addition to the podcasts, participants will be asked to track their diet using an assigned mobile applications (for their smartphone), which will be randomly assigned.

Study Overview

• Status: Completed
• Conditions: Obesity
• Intervention / Treatment: Behavioral: Photo App; Behavioral: Podcasts; Behavioral: Diet App

Detailed Description

This study will include an intensive phase for 6 weeks and a follow-up phase that will occur through the final 6 months of the study. Participants will attend one 1-hour orientation meeting at the beginning of the study and a 2-hour baseline assessment and training meeting. A final assessment will be conducted at the end of 6 weeks with a follow-up assessment at 6 months. Everyone in the study will be asked to listen to 2 podcasts per week. Each of the podcasts will take about 15-20 minutes to listen to and so participants should expect to spend 30-40 minutes each week listening to podcasts. Participants also will be randomized to track diet with one of the two mobile dietary tracking applications that will be used in the study. Participants will be encouraged to monitor their exercise and body weight.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Photo App; Participants in this group will receive podcasts twice weekly in conjunction with using a mobile dietary tracking application(Photo App). This Photo App allows participants to track meals by taking photos.	Behavioral: Photo App; Use of a mobile photo app that takes pictures of foods consumed and allows users to share these pictures with other members of the study in order to receive feedback.; Behavioral: Podcasts; Listen to 2 podcasts per week about healthy eating and exercise.
Active Comparator: Diet App; Participants in this group will receive podcasts twice weekly in conjunction with an app (Diet App) to track their diet by entering in foods and beverages consumed.	Behavioral: Podcasts; Listen to 2 podcasts per week about healthy eating and exercise.; Behavioral: Diet App; Use of a mobile diet app that allows users to track all foods and beverages consumed in order to calculate the calories consumed each day.
