About this study
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.
Read the detailed description
This research includes three phases:
- To better understand the motivators and inhibitors of skin cancer risk behaviors in various populations including use of indoor tanning and outdoor sun exposure;
- To develop content messages and images related to skin cancer risk that are resonant with various populations;
- To test the relative effectiveness of these messages in reducing likelihood of or actual skin cancer risk behaviors in various populations.
- Conditions
- Skin Cancer
- Being tested
- Prevention video advertisement, Prevention images for advertisement, No Advertisement
- Medical subject headings
- Skin Neoplasms
