Timeline
Interventions
Participants received two daily notifications. Each notification included a question about a variable from the HAPA model, and participants responded on a 5-point Likert scale. Those who scored low (1-3) received a motivational message tailored to their response. In contrast, participants who scored high (4-5) received rewarding messages. These notifications gave participants feedback on their standings within the HAPA.
Participants received two daily educational notifications about HAPA variables, but they did not interact with the app. The notifications for both the HAPA-I and HAPA-NI groups were identical in structure, word count, and graphic format. The only difference was the level of content customization: it was generic for the HAPA-NI group and tailored to participants' responses for the HAPA-I group.
Participants received a daily reminder to log the portions of fruit and vegetables in a dedicated self-monitoring section of the app.
