Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Approach: An elicitation survey among 80 SGM youth and focus group discussions among a subsample of 48-64 youth who complete the elicitation survey will explore beliefs related to vaping initiation that SGM youth find most salient. Participants will include US SGM youth, ages 12-18 years, stratified by age (12-15 or 16-18), vaping status (never vaped and are susceptible or have initiated vaping in the past 1 year), and gender identity (cisgender or transgender/gender expansive). The investigators will further explore the social contexts of their vaping behavior and preferences for cultural tailoring of anti-vaping messages (i.e., peripheral, evidential, linguistic, and sociocultural values tailoring) among SGM youth.
Aim 2: Identify promising anti-vaping social media messages and cultural tailoring strategies to reduce vaping initiation among SGM youth.
Approach: Results from Aim 1 and input from community stakeholders will be utilized to develop SGM-tailored social media anti-vaping messages. An online discrete choice experiment among SGM youth ages 13-18 years (n=600) who have never vaped will be used to test the impact of anti-vaping messages and cultural tailoring strategies on perceived message effectiveness to reduce vaping initiation. Results will guide the construction of culturally tailored anti-vaping social media intervention for broader evaluation in Aim 3.
Aim 3: Evaluate the effectiveness of repeated exposure to SGM-tailored anti-vaping social media messages on subsequent vaping susceptibility among SGM youth.
Approach: The investigators will conduct a prospective 2-group randomized experiment among 1500 SGM youth and young adults ages 13-20 to test the hypothesis that repeated exposure to SGM-tailored anti-vaping social media messages will be associated with reduced vaping susceptibility, defined as the extent to which youth are open to vaping, compared with non-tailored messages.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Tailored
Participants in the tailored arm will receive SGM-tailored anti-vaping health messages delivered via text message
Tailored
Messages will be in the form of high-quality English-language anti-vaping messages comprising static text and imagery designed to resemble social media posts (e.g., image and a caption). We will create 24 messages based on the top-ranked tailoring features and belief themes tested in Aim 2 to comprise SGM-tailored messages. For the non-tailored message condition, we will create 24 anti-vaping social media messages that mirror the SGM-tailored messages but do not contain SGM identity cues. We will match the belief themes used in the tailored and non-tailored messages such that they represent a range of belief targets (e.g., addiction, physical health effects, mental health effects) as indicated in Aims 1 and 2. We do not utilize a social media platform for the delivery of the message to avoid potential contamination across randomized conditions.
Non-Tailored
Participants in the non-tailored arm will receive non-tailored anti-vaping health messages delivered via text message
