Interventions

• Message Exposure via Discrete Choice Experiment — BEHAVIORAL
  Participants will view 64 anti-smoking social media messages, presented across 16 choice sets, in a discrete choice experiment (DCE) with eye-tracking. Within each choice set, participants indicate which message most attracts their attention, which they would be most likely to share or repost, and which would most motivate them to quit smoking.

Study Details

\<p\>The goal of this clinical trial is to learn how exposure to anti-smoking social media messages affects quitting-related behaviors. Eligible participants will be adults aged 21 or older who have used menthol cigarettes on at least 4 days during the past 30 days.\</p\> \<br\> \<p\>The main question this study aims to answer is: Does exposure to anti-smoking messages (in the context of a discrete choice experiment \[DCE\] with eye-tracking study) increase quitting-related behaviors over the following 2 weeks?\</p\> \<br\> \<p\>Participants will be randomly assigned to view the messages either immediately or after a 2-week waiting period, allowing researchers to compare quitting-related behaviors between the two groups. The primary outcome is whether participants report making a quit attempt in the 2 weeks following randomization.\</p\> \<br\> \<p\>Participants will:\</p\> \<ul\> \<li\>Complete eligibility screening and baseline questions about demographics and tobacco use.\</li\> \<li\>Be randomly assigned to view the messages immediately or after a 2-week waiting period.\</li\> \<li\>Attend a 1-hour in-person study visit at Georgia State University or the University of California, Santa Barbara.\</li\> \<li\>View 64 anti-smoking social media messages presented in 16 choice sets while their eye movements and pupil dilation are measured using a screen-based eye-tracking device.\</li\> \<li\>Select which messages most attract their attention, which they would be most likely to share, and which would most motivate them to quit smoking.\</li\> \<li\>Complete questions about quitting-related behaviors either during the study visit (waitlist control condition) or through an online questionnaire 2 weeks later (immediate condition).\</li\> \</ul\>

Arms

• Experimental: DCE exposure
  Participants complete the in-person discrete choice experiment (DCE) with eye-tracking study visit immediately after randomization. During this visit, participants view 64 anti-smoking social media messages presented in 16 choice sets while their eye movements are recorded. Participants then complete an online questionnaire assessing quitting-related behaviors 2 weeks later.
• No Intervention: Waitlist Control
  Participants wait 2 weeks following randomization. At the start of an in-person visit conducted at the end of this waiting period, participants answer questions about quitting-related behaviors covering the preceding 2-week waiting period. Participants then complete the discrete choice experiment (DCE) with eye-tracking study.

Primary Outcome Measure

Quit attempts [ Time Frame: 2 weeks after message exposure for the immediate intervention arm and 2 weeks before message exposure for the waitlist control arm. ]
