Summary

The purpose of this study is to test the efficacy of an innovative 6-month smartphone-delivered intervention using simplified monitoring of dietary intake compared to a smartphone-delivered intervention with standard calorie monitoring among parents with overweight or obesity.

Detailed description

This is a 6-month randomized controlled trial comparing the efficacy of two smartphone-based dietary and weight change interventions among 70 parent-child dyads with at least one child between the ages of 2 and 12 (70 adults and 70 children ages 2-12). One intervention group (Simple) will use a simplified, low-burden form of dietary tracking in the study smartphone application and the other group (Standard) will use standard calorie tracking. Components of both interventions include (1) setting personalized goals for weight, dietary intake, and daily activity (2) adaptive text message interventions based on behavior change techniques such as goal setting and in-the-moment progress feedback several times per week, (3) weekly tailored feedback updated in the study smartphone app, and (4) weekly lessons on the smartphone app. The primary objective is to promote weight loss in the parents, and the secondary objective is to determine if one or both interventions produce a ripple effect of parent dietary change onto dietary changes in the child.

Interventions

Type	Name	Description
BEHAVIORAL	Simple	Participants have three daily goals (weighing, dietary goal, activity goal), will self-monitor (weigh on Wi-Fi enabled scale, use a simplified form of tracking only high-calorie, high-fat foods in the study smartphone app, wear Fitbit activity tracker), will receive 4-5 tailored text messages each week, and will view weekly tailored feedback and lessons in smartphone app.
BEHAVIORAL	Standard	Participants have three daily goals (weighing, dietary goal, activity goal), will self-monitor (weigh on Wi-Fi enabled scale, track calorie intake, wear Fitbit activity tracker), will receive 4-5 tailored text messages each week, and will view weekly tailored feedback and lessons in smartphone app.
