About this study

The goal of this research is to determine how removal of little cigar and cigarillo (LCC) flavor descriptors on packaging impacts attention and affective responses to LCC warnings. A study will be conducted using eye tracking, electrodermal activity (galvanic skin response), and survey measures of affect to measure participant responses to LCC packages varied by warning type (pictorial vs. text only) and flavor contents ('Sweet' flavor descriptor vs. no flavor descriptor).

Read the detailed description

Over 4 million US adults regularly smoke cigars, which causes multiple cancers, including oral, esophageal, pancreatic, laryngeal, and lung cancer. Even smoking 1-2 cigars per day is associated with elevated cancer risk. Though cigarette consumption decreased 39% from 2000 to 2015, cigar consumption increased 85%. Of the three major types of cigars-large cigars, little cigars, and cigarillos-little cigars and cigarillos (LCC) are the most commonly used in the US. LCC use among adults has increased in part because LCCs are taxed at a lower rate than cigarettes, are subject to fewer regulations and marketing restrictions, can be purchased in small pack sizes, and are exempt from flavor bans that apply to cigarettes.

In May 2016, the Food and Drug Administration (FDA) required text-only warnings on LCC packs, rotating among six statements. Research on cigarettes suggests warnings on packs should have multiple rotating sets, contain images illustrating the negative health effects associated with LCC use, and be large. However, the evidence for cigarette warning labels cannot adequately inform implementation of improved LCC warnings for four reasons: 1) The currently mandated cigar warnings differ from existing cigarette warnings; 2) there is no evidence on the effectiveness of the currently mandated cigar warnings (i.e., behavioral intentions or outcomes) or evidence on efforts that might improve LCC warnings (i.e., images, larger warning size, removal of LCC flavor descriptors on packaging); 3) Courts have ruled that one type of effective tobacco warning (i.e., for cigarettes) cannot be used to justify other types of tobacco warnings, such as those for LCCs and 4) LCC users have different demographic and consumption profiles than cigarette users (i.e., LCC users include a higher proportion of young adults African Americans, and LCCs are used on fewer days per month, which should be taken into account when developing improved warnings.

Gaps exist in understanding how LCC policies, such as the removal of flavor descriptors on packaging, influence the impact of LCC warnings. This eye tracking and psychophysiology project will provide new data to fill these evidence gaps and advance general scientific knowledge about elements of tobacco warnings research.

During the study, Participants will see 12 LCC pack stimuli images presented in random order. 3 packs will feature pictorial LCC warnings and a "Sweet" flavor descriptor, and the same 3 warnings will be presented on packs without a flavor. The remaining 6 LCC packs will have 3 text-only warnings, with 3 images containing the "Sweet" flavor and 3 images without a flavor. We will measure attention to the warnings and attention to the flavor descriptors as well as electrodermal activity and affective responses for each of the 12 stimuli.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Attention to Warning Areas of Interest

    Mean attention to warning areas of interest in seconds will be measured by dwell time to pre-defined areas of interest on the LCC packages. The mean amount of time in seconds that participants spend looking at the flavor area of interest for the 3 packages in each condition will be determined.

    Measured: During one time study appointment

  2. Attention to Flavor Areas of Interest

    Mean attention to flavor areas of interest in seconds will be measured by dwell time to pre-defined areas of interest on the LCC packages. The mean amount of time in seconds that participants spend looking at the flavor area of interest for the 3 packages in each condition will be determined.

    Measured: During one time study appointment

Secondary outcomes (2)
  1. Positive Affect

    Mean positive affect response to warnings will be measured using an adaptation of the Discrete Emotions Questionnaire. The positive affect questionnaire will include 6 different emotions to measure participant's emotional responses to the cigarillo packages. Participants will rate to what extent they experienced each emotion while viewing the LCC package on a scale of 1 to 7, where 1=not at all and 7=an extreme amount. Higher affective responses indicate stronger positive emotional reactions to the LCC package. The mean positive affect will reflect the mean positive affect rating for the 3 packages in each condition.

    Measured: During one time study appointment

  2. Negative Affect

    Mean negative affect response to warnings will be measured using an adaptation of the Discrete Emotions Questionnaire. The negative affect questionnaire will include 6 different emotions to measure participant's emotional responses to the cigarillo packages. Participants will rate to what extent they experienced each emotion while viewing the LCC package on a scale of 1 to 7, where 1=not at all and 7=an extreme amount. Higher affective responses indicate stronger negative emotional reactions to the LCC package. The mean negative affect will reflect the mean negative affect rating for the 3 packages in each condition.

    Measured: During one time study appointment

Questions about this trial

What is this clinical trial studying?

A study testing LCC pack stimuli images in people with Tobacco Use, run by UNC Lineberger Comprehensive Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Attention to Warning Areas of Interest (time frame: During one time study appointment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
