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.

Interventions

Type	Name	Description
BEHAVIORAL	Outdoor Sun Behavior	Participants will provide informed consent and complete a short background questionnaire about usual sun exposure and protection behaviors and demographics. Next, each participant will be seated in a room to view the audio-visual media messages. Eye-tracking equipment running Paradigm (Perception Research Systems Incorporated) for stimuli presentation will be calibrated to the participant. Subjects will be seated at a desk in front of a computer monitor, keyboard and mouse setup. Each participant will view messages with different emotional appeals related to outdoor sun exposure (seeking shade, covering up, using sunscreen, and multiple behaviors). Messages will be shown in random order, with each message interspersed by a 30 second baseline screen consisting of black background and white, centered plus sign. The last 10 seconds of each preceding the 30-second baseline screen will be used to establish physiologic baseline to minimize carry-over effects of the preceding message.
BEHAVIORAL	Indoor Tanning Behavior	Upon arrival, participants will provide informed consent and complete a short background questionnaire about usual indoor tanning, sun exposure and protection behaviors, and demographics. Next, each participant will be seated in a room to view the audio-visual media messages. Eye-tracking equipment running Paradigm (Perception Research Systems Incorporated) for stimuli presentation will be calibrated to the participant. Subjects will be seated at a desk in front of a typical computer monitor, keyboard and mouse setup. Each participant will view messages with each type of target behavior (freedom, health risk, appearance)). Messages will be shown in random order, with each message interspersed by a 30 second baseline screen consisting of black background and white, centered plus sign. The last 10 seconds of each preceding the 30-second baseline screen will be used to establish physiologic baseline to minimize carry-over effects of the preceding message.
