Brief Summary

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

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Perceptions of harm of flavored cigarillos products versus unflavored cigarillo advertisements	One week after exposure to product advertisements	Perceptions of harm of flavored cigarillos products versus unflavored cigarillo advertisements (assessed on absolute and relative risk scales).; Perception of Harm scores are on a 3-point scale: Less harmful, about the same level (or as harmful), and more harmful. Higher values indicate more perceived harm while lower values indicate less perceived harm.
Likelihood of flavor use - Aim 1 survey	At baseline	Participants are asked how likely they are to use six flavors of cigarillos on a four-point scale from Definitely Never Use to Regularly Use.
Appeal scores of flavored versus unflavored cigarillos in cigarillo users based on initial online survey scores	At baseline	Within-subjects analyses (one sample paired t-tests) will be used to assess appeal scores of flavored versus unflavored cigarillos in cigarillo users based on initial online survey scores.; Appeal Scores are on a 7-point LIKERT Scale from Strongly Disagree to Strongly Agree for three indicators. High values indicate higher greater appeal while low values indicate lower appeal.
Visual attention as assessed by dwell time visual attention on product packages	Immediately after exposure to product advertisements	Visual attention as assessed by dwell time visual attention on product packages across a set of only flavored, only unflavored or mixed flavor advertisements
Attentional bias in flavored cigarillos products versus unflavored cigarillo advertisements	Immediately after exposure to product advertisements	Attentional bias in flavored cigarillos products versus unflavored cigarillo advertisements. Attentional bias is defined as greater duration of attention to flavored stimuli.
