简要总结
This study aims to evaluate the efficacy of a healthy diet promotion intervention focused on increasing fruit and vegetable consumption. The intervention is delivered via mobile application in a sample drawn from the healthy adult population.
详细描述
The present study aims to evaluate the effectiveness of a protocol designed to increase fruit and vegetable consumption, grounded in the Health Action Process Approach (HAPA).
The protocol was delivered via the MyPocketHealth app, developed by the research team, and incorporated different communication strategies. Participants were involved in setting a goal and choosing between a personalized or a standardized goal (5 daily portions), which could be reviewed at any time. Moreover, they received either interactive (HAPA-I: group 1) or non-interactive (HAPA-NI: group 2) daily notifications promoting the target behavior through HAPA constructs for 15 days, while also monitoring their daily fruit and vegetable consumption (self-monitoring). A third group engaged solely in self-monitoring without receiving any communication (no-communication group; No comm). Goal attainment was reinforced through badge awards (rewards).

盲法说明
The baseline assessment, the intervention, and the post-intervention assessment are provided automatically via the mobile app. In addition, participants are randomly assigned to a specific experimental group before the study begins and do not know which group they are assigned to. These features of the study minimize observer bias.
