Hypothesis
Tailored online interventions will lead to greater participant engagement and improved dietary outcomes compared to untailored interventions.
Conclusion
Tailored interventions significantly increased participant engagement and positively influenced dietary changes.
Supporting Evidence
- Participants in tailored intervention arms showed significantly more engagement than those in the untailored arm.
- Greater engagement was associated with higher retention rates in follow-up surveys.
- Engagement measures were significantly correlated with positive changes in fruit and vegetable consumption.
Takeaway
This study shows that when people get personalized help online, they are more likely to stick with it and eat more fruits and vegetables.
Methodology
Participants were randomized into three groups and their engagement was measured through paradata analysis of their online interactions.
Potential Biases
Potential bias due to the use of incentives for participation and reliance on automated reminders.
Limitations
Findings may not generalize to all Internet users due to eligibility requirements for Internet access and email accounts.
Participant Demographics
Participants were aged 21 to 65, with 69% women, 66% white, 24% African American, and 8% Hispanic.
