Trial Outcomes & Findings for Nicotine and Tobacco Message Framing Among LGBT Young Adults (NCT NCT05972941)

Participants who consented to the study but did not complete the activity in REDCap that triggered randomization to an arm, were excluded from the rest of the study.

Nicotine and Tobacco Message Framing Among LGBT Young Adults

Visual attention measured by dwell time (milliseconds) on areas of interest (AOI; e.g., text, graphic) within a stimuli was assessed via eye-tracking for each message (n=8). Dwell times on AOIs were summed for all stimuli viewed by each participant and averaged. Scores represent total average dwell time on AOIs across stimuli.

Time (milliseconds) to first fixation on areas of interest (text, graphic) within a stimuli was assessed via eye-tracking for each message (n=8). Time to first fixation on a specific AOI was summed for all stimuli viewed by each participant and averaged. Scores represent total average time to first fixation on AOIs across stimuli.

6-items on a 5-point scale where 1 = Not at all and 5 = Very much. Please rate each statement from 1 (not at all) to 5 (very much). These message are worth remembering. These messages grabbed my attention. These messages are powerful. These messages are convincing. These messages are meaningful. These messages are informative. Individual items are summed and averaged for a total score ranging from 1 to 5. Higher scores indicate a better outcome.

6-items. 5-point scale where 1 = Strongly disagree to 5 = Strongly agree These messages discourage me from smoking cigarettes. These messages make me concerned about the negative effects of smoking cigarettes These messages make smoking cigarettes seem unpleasant to me. 3-items above are summed and averaged. Higher scores indicate better outcome. These messages discourage me from vaping nicotine. These messages make me concerned about the negative effects of vaping nicotine. These messages make vaping nicotine seem unpleasant to me. 3-items above are summed and averaged for a total score ranging from 1 to 5. Higher scores indicate a better outcome.

8 items total. 4-point scale 1 = Definitely not to 4 = Definitely will. The following items were asked at baseline and post-exposure. How likely is it that in the next 3 months, you will refrain from vaping nicotine.... * completely and permanently? * when you get lonely? * when you are with your friends who use them? * when someone hands you a vape? How likely is it that in the next 3 months, you will refrain from smoking cigarettes... * completely and permanently? * when you get lonely? * when you are with your friends who use them? * when someone hands you a cigarette? For each subscale, pre-test and post-test items were summed and averaged. Change scores were calculated for each subscale by subtracting pre-test scores from post-test scores. Change scores could range from 0 to 3. Higher change scores indicate a better outcome (i.e. greater change in intentions to refrain from smoking or vaping)

Number of participants who answer "Yes" to the following: Do you plan to quit smoking cigarettes in the next 30 days? (Yes/No)

Number of participants who answer "Yes" to the following: "Do you plan to quit vaping nicotine in the next 30 days?" (Yes/No)

3-items; 5-point Likert scale where 1 = Strongly disagree and 5 = Strongly agree These messages are trying to manipulate me. These messages annoy me. The health effects of these messages are overblown. Items are summed and averaged for a total score ranging from 1 to 5. Higher scores indicate a worse outcome.

5 items; 7-point Likert scale where 1 = Strongly Disagree and 7 = Strongly agree These ads were created just for me. These ads were created for people like me. These ads were relevant to me. These ads were of value to me. These ads were important to me. Items were summed and averaged for a total score ranging from 1 to 7. Higher scores indicate a better outcome.

Single item; 5-point Likert scale where 1 = Strongly disagree and 5 = Strongly agree I like these messages.

Two items; 7-point Likert scale where 1 = These message made me feel much worse and 7 = These message made me feel much better. Did these messages change how you feel about smoking combustible cigarettes? Did these messages change how you feel about vaping nicotine? Higher scores mean a worse outcome.

6-items; 5 point Likert scale where 1 = Strongly disagree and 5 = Strongly agree These messages will motivate CIGARETTE SMOKERS to switch to vaping. These messages will motivate people to quit ALL smoking and vaping. These messages will motivate NON-USERS to start vaping. These messages will motivate NON-USERS to start smoking cigarettes. These messages will motivate CIGARETTE SMOKERS to quit. These messages will motivate VAPERS to quit. Higher scores mean a better outcome.

Participants will be asked the following question: "The images that you viewed included health messages. What do you remember about the health messages?" Outcome indicates then number of participants who qualitatively reported recalling something about the health message.
