Summary

The goal of this clinical trial was to test the preliminary efficacy of a digital dietary self-monitoring (dDSM) log that uses positive reinforcement strategies (caregiver praise and gamification) to improve child engagement in DSM. The main aims were to:

* Conduct a proof-of-concept trial that examines the effects of positive reinforcement on child DSM behaviors.
* Explore differences in children's intrinsic motivation.

Participating children will be instructed to self-monitor their daily intake of targeted food groups (fruits, vegetables, sweet and salty snack foods, and sugar-sweetened beverages) for 4 weeks using a personal web-based DSM log. Each child-caregiver dyad will be randomly assigned to 1 of 4 conditions: BASIC, PRAISE, GAME, or PRAISE+GAME. For PRAISE and PRAISE+GAME conditions, caregivers will be instructed to provide daily process praise to their child related to DSM behaviors. For GAME and PRAISE+GAME conditions, logs will integrate three game mechanics: points, levels, and a virtual pet. Points will be accumulated for engaging in DSM behaviors, and accrual of points will evolve a virtual pet over time.
