Overview

Brief Summary

The overall goal of this research is to develop interventions that leverage online technology (e.g. ads, social media) to reduce individuals' skin-cancer-related risk behaviors and ultimately to reduce skin cancer incidence.

Detailed Description

This research includes three phases: 1. To better understand the motivators and inhibitors of skin cancer risk behaviors in various populations including use of indoor tanning and outdoor sun exposure; 2. To develop content messages and images related to skin cancer risk that are resonant with various populations; 3. To test the relative effectiveness of these messages in reducing likelihood of or actual skin cancer risk behaviors in various populations.
