Reducing UV Exposure to Prevent Skin Cancer: Message Development & Testing

Not Applicable

Completed

• Conditions: Behavior, Health
• Interventions: Behavioral: Outdoor Sun Behavior; Behavioral: Indoor Tanning Behavior

• Registration Number: NCT03201120
• Lead Sponsor: University of Pennsylvania

Brief Summary

Phase 3b of the research will be a laboratory experiment that uses an experimental and analytic design that is parallel to that used in Phase 3a, the online experiment. The primary objective of Phase 3b is to assess physiological response (i.e., eye tracking) to different message appeals of the audio-visual messages used in Phase 3a on respondents' behavioral intentions and UV-related behavioral choices post-exposure. Including time for preparation, viewing, and removal of the monitoring equipment, the message viewing session will take about 45 minutes per session.

Arm && Interventions

Group	Intervention	Description
Outdoor Sun Exposure Behavior	Outdoor Sun Behavior	A convenience sample of white, English-speaking adults ages 18 to 49 will be recruited via online advertisements in Philadelphia and the surrounding region (within a 30 mile radius). The investigators will recruit 120 adults to test outdoor UV exposure messages. The investigators will quota sample to ensure representation across age and gender groups. The inclusion criteria are that adults must be white, must be between 18-49 years old and must speak English.
Indoor Tanning Behavior	Indoor Tanning Behavior	A convenience sample of white, English-speaking females ages 18 to 25 will be recruited via online advertisements and flyers in Philadelphia and the surrounding region (within a 30 mile radius). The investigators will recruit 60 adults to test indoor tanning messages. The inclusion criteria are that adults must be white, female, must be between 18-25 years old, must have used an indoor tanning bed at least once in the past 12 months, and must speak English.

Primary Outcome Measures

Name	Time	Method
Follow-up Survey	Two weeks post baseline Laboratory Survey	Two weeks after the completed laboratory session, participants will be emailed a link to complete a follow-up survey. The survey will ask about participants' ability to recall the messages, attitudes regarding outdoor sun protection behaviors, actual behaviors in the past two weeks, whether the participants have used or will use the product they selected, and whether the participants have discussed the messages with anyone else.
Laboratory Survey	Baseline	Questionnaire measures will be completed using an iPad with Qualtrics software. Participants will be asked to evaluate each message for its argument strength, emotional appeal, and themes; participants will also be asked about their intentions and beliefs related to each behavior. The research technician will not initiate a conversation with the participant during the experimental session except to give instructions.

Secondary Outcome Measures

Name	Time	Method
Measure of Behavioral Intent	Baseline	Upon finishing the experiment, respondents will be offered a choice of one of four "thank you" gifts of comparable value: sunscreen, hand sanitizer, and moisturizer with or without SPF protection. The experimenter will unobtrusively record the subjects' selections.
