This document summarizes a study on designing an intervention to encourage college students to apply sunscreen daily. The intervention involved sending daily email reminders with weather and UV index information, and a Google form to track sunscreen use. Over 6 students, the average number of days applying sunscreen was 7.1 days, with 1.3 days on average missed. The emails and forms were effective, with an 81% daily success rate on average. Areas for improvement include more automated reminders and tracking to create stronger habits.

4. Storyboard: Susie Uses Sunscreen! 1. Susie wakes up for the morning. 2. Naturally, as a sorority girl, Susie checks her emails and texts first thing. 3. Susie gets an email on her BlackBerry/laptop! 4. The email reminds Susie to apply facial sunscreen and informs her of the weather and the daily UV index. 5. The email also provides Susie with a Google form in which she can track her sunscreen use - even from her mobile phone! 6. Susie puts sunscreen on and fills out the easy Google form straight from the reminder e-mail. 7. Susie tracks her progress (and her sisters' progress) through the link at the bottom of the email to the Google form results. 8. Susie sends a sunscreen reminder via text to her sister, Sarah, after not seeing her name on the results sheet.
