Clinical Trial Summary

The purpose of this research is to understand how flavor affects young adult's perceptions of little cigar or cigarillo use.

Description:

The overall goal of this study is to examine and better understand adolescent and young adult perceptions, visual attention, use intentions and purchasing behaviors among users and non-users of cigarillos. Supplemental Aim 1: Consists of evaluation of the differences in perceptions of flavors on appeal, purchasing and risk perceptions of cigarillo products between young adult sexual and gender minorities (SGM) and heterosexual females. A convenience sample of SGM females will be recruited using online social media platforms with targeted advertising. From the parent survey (or Aim 1), an existing sample of female heterosexual cigarillo users will be leveraged. Both samples will receive the same survey, Aim 1, to compare perceptions of appeal, risk, and purchasing across cigarillos and other tobacco products. Aim 1 of this study is exploratory and will consist of an online survey. Findings from Aim 1 will inform the questions asked about advertising and product use in Aim 2 and 3. Both Aim 2 and 3 are randomized sections. Participants in Aim 2 are either tobacco users or non-users. Participants will be asked to view a series of tobacco related images. The sequence of those images is randomized. In Aim 3, participants will be randomized in terms of the options they are presented within the Experimental Tobacco Marketplace (ETM) (i.e. which tobacco items they can purchase and at what price). Supplemental Aim 3 consists of evaluating the differences in the abuse liability/addictive potential of flavored versus unflavored cigarillos and the substitutability of flavored versus unflavored disposable e-cigarettes between young adult sexual and gender minorities (SGM) and heterosexual females. SGM female cigarillousers will be recruited from participants of the Supplemental Aim 1 sample and be compared to heterosexual female participants of the parent study (or Aim 3). Both samples will receive the same questions and be exposed to the same ETM conditions tocompare perceptions of appeal of flavors and substitutability between cigarillos, e-cigarettes, and other tobacco products.

Intervention

Other:
• Aim 1: Online survey
This survey will evaluate perceptions of flavors on appeal, purchasing and risk perceptions of cigarillo products among young adult and adolescent cigarillo users. This survey will be used to inform survey design for further aims. As a proxy for biological verification of tobacco use status, data on brand, frequency, and pricing will be collected to confirm user status Participants will rate the role of flavor and report perceptions of product appeal, health risk, advertising exposure and use intentions. Participants will also complete purchase and substitution tasks.

Behavioral:
• Eye Tracking Activity
The eye tracking activity consists of a single in-person eye tracking activity that will take place in a private office in Columbus, Ohio where the participant will be seated in a chair within a typical viewing distance from a computer monitor equipped with an infrared camera on the monitor to capture precise eye movements. Participants will have their gaze monitored continuously by the camera on the computer monitor while a randomized set of stimuli (e.g., tobacco product images) are viewed (n=30) for 10 seconds per image. Following each image, an on-screen closed response question will re-center the participant's gaze for standardization prior to the next image.

Other:
• Eye tracking survey
Other Names: Participants will complete a survey using Qualtrics immediately after the eye tracking activity and one week following completion of the activity via email to measure recall of brand name, product flavors, perceptions of cigarillo harm, and tobacco use behaviors and intentions.

Behavioral:
• Online Experimental Marketplace (ETM)
Administered online via Qualtrics Participants are given an account balance for use during their assigned ETM based on their average weekly tobacco use calculated from previous interview. Participants will view all four price conditions and all four flavor conditions in random order for a total of 16 rounds Cigarillo price conditions: 1) market price 2) ½ market price 3) 2X market price 4) 4X market price Flavor condition: 1) flavored cigarillos and fruit-flavored disposable-cigarettes available 2) unflavored cigarillos and fruit-flavored ecigarettes available 3) flavored cigarillos and tobacco-flavored e-cigarettes available 4) unflavored cigarillos and tobacco-flavored e-cigarettes available. Participants will purchase cigarillos with their account balance. During all ETM conditions, constant-priced alternative tobacco products (smokeless tobacco, nicotine lozenges, nicotine gum, and the nicotine patch) will be available in addition to the cigarillos and e-cigarettes.

Other:
• Aim 3 survey
Consists of: A screener and demographic data collection. A tobacco product withdrawal scale Upon completion of the ETM, participants will be asked to respond to a quality assurance question regarding the conditions that varied. Participants will be shown a list of 8 possible conditions and must chose one of the three that varied in order to be eligible to receive compensation. The tobacco product withdrawal scale again Measurements of nicotine dependence and flavor preferences
• Cognitive Interviews
Cognitive Interviews will be done in-person, using Zoom, or over the phone. Interviews will be video or audio recorded. . The participant will be given a select section of the survey questions from Aim 1. The survey will be uploaded to Qualtrics to reflect the way that survey would be conducted in Aim 1. With the survey questions in front of the participant on the computer screen, research personnel will ask probing questions about each one of the survey questions. If the participant is not able to participate in person or via Zoom, they will be allowed to be interview over the phone with access to the Qualtrics survey or a paper form. If the participant is unable to access the internet, the participant will be read the questions by research personnel. The participant will provide feedback about the questions and walk the research personnel through their thought process for approaching each survey question.
• Supplemental Aim 1 Interviews
Participants from the preceding online survey (who identify as women from Aim 1/supplemental aim 1 survey) who agreed to be contacted for future study will be emailed an invitation to the eligibility screener. Individuals interested will complete a screener to ensure participants identify as women and to verify that they have ever used cigarillos. Eligible participants will be contacted to schedule a 60- to 90-minute Zoom interview about their tobacco, nicotine, and cannabis product use experiences, with particular focus on flavored cigarillo usage initiation, current use, and responses to potential flavor restrictions.
