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

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.

Treatment and study plan

Outdoor Sun Behavior

Behavioral

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.

Indoor Tanning Behavior

Behavioral

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.

Primary outcomes

  1. Laboratory Survey

    Time frame: 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.

  2. Follow-up Survey

    Time frame: 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.

Secondary outcomes

  1. Measure of Behavioral Intent

    Time frame: 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.
