Social Media Indoor Tanning Study

Study Overview
=================
Brief Summary
-----------------
The purpose of this research is to develop a social media delivered intervention to reduce unprotected sun exposure in young adults with a history of tanning.

Detailed Description
-----------------
We will use social marketing theory and a user-centered design approach to develop a social media intervention that engages young adults with a history of tanning to practice sun safety behaviors. We will incentivize young adults who have a history of tanning to create social media posts that encourage their peers to engage in sun safety. Focus groups of tanners guided the development of the intervention. Investigators will conduct a pilot feasibility trial where participants will be randomized to a condition in which they are incentivized to create sun safety social media messages to be posted on a sun safety social media account or a condition in which they are incentivized to create social media messages about how to use technology to support healthy lifestyle behaviors to be posted on a health technology social media account. The intervention will last 4 weeks. Feasibility outcomes include recruitment, retention, acceptability, participation, social media message engagement (likes, comments, shares), persuasive impact of messages, unprotected sun exposure, sun protection, and tanning behavior. This work will inform a fully powered randomized trial testing the efficacy of this intervention.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Sun Safety Social Media Challenge<br>During this 4-week intervention, participants will be incentivized to create sun safety social media messages that will be distributed on our sun safety Twitter and Facebook feeds. | Behavioral: Sun Safety Social Media Challenge<br>* Participants will attend a webinar to learn how to create effective social media posts about sun safety and be oriented to the social media accounts on which the messages will be posted. They will be informed that posts should include a sun safety message (e.g., promoting sunscreen use and protective clothing/hats or discouraging risk behaviors like tanning and burning). They will be encouraged to be creative so that the message gets likes and shares. Participants will be encouraged to follow the feeds to see the engagement on their posts, to share the posts in their feed, and to see other participants' posts. Participants will receive a $10 Amazon gift card per post for a maximum of 6 posts ($60). The participant who created the post that receives the most likes, comments, and shares each week will win a $50 Amazon gift card.<br>|
| Active Comparator: Digital Health Social Media Challenge<br>During this 4-week intervention, participants will be incentivized to create posts that promote the use of technology to engage in healthy lifestyle behaviors (diet, exercise) on our digital health Twitter and Facebook feeds. | Behavioral: Digital Health Social Media Challenge<br>* Participants will attend a webinar to learn how to create effective social media posts about using technology to get healthy and be oriented to the social media accounts on which the messages will be posted. They will be informed that posts should mention some way that technology (e.g., mobile apps, wearables) can be used to promote a healthy habit (e.g., diet, exercise). They will be encouraged to be creative so that the message gets likes and shares. Participants will be encouraged to follow the feeds to see the engagement on their posts, to share the posts in their feed, and to see other participants' posts. Participants will receive a $10 Amazon gift card per post for a maximum of 6 posts ($60). The participant who created the post that receives the most likes, comments, and shares each week will win a $50 Amazon gift card.<br>|
