Measuring Nicotine Dependence Among Adolescent and Young Adult Cigarillo Users.

INTRODUCTION: Current measures of nicotine dependence (ND) were developed and validated for cigarette smokers only, limiting their utility for other combustible tobacco users. This study evaluates the psychometric properties of a pool of new and adapted items to measure ND among cigarillo and multiple tobacco product users. AIMS AND METHODS: Items were drawn from the PROMIS Nicotine Dependence Item Bank which were adapted to be product neutral and new items were developed from a qualitative study of 60 adolescent and young adult cigarillo smokers. A total of 42 ND items were included in a web-based survey. Eligible participants were 14-28 year olds who smoked a minimum of 2 cigarillos per week. Analyses included confirmatory factor analysis, item response theory analysis, analysis of differential item functioning, and reliability. Ordinary least square regression was used to test the association of ND score with deciles of nicotine consumption. RESULTS: Among the 1089 participants, the median number of cigarillos smoked per week was 20; 54% of participants also smoked cigarettes. All PROMIS items and 8 of 10 new items met the item response theory fit criteria. Two PROMIS items had nonignorable differential item functioning. The pool of 40 items had good score reliability for a range of 2 SDs. Twenty-, eight-, and four-item short forms showed similarly good measurement properties; each was positively associated with decile of nicotine consumption, p < .001; R2 = 0.33. CONCLUSIONS: This adapted bank of ND items is psychometrically sound and includes items that are product neutral, making it suitable for assessing ND among cigarillo and polytobacco users. IMPLICATIONS: This study rigorously evaluates adapted items to measure ND among cigarillo and polytobacco users and reports the reliability initial evidence of validity of short form scores.

"I got a little addiction": Adolescent and young adult cigarillo users' self-perceptions of addiction.

BACKGROUND: While prior research has informed how cigarette smokers understand and apply the term addiction, little is known about how this term is used by cigarillo smokers. This is an important area of study given the decline in cigarette use and increase in cigar product consumption. PURPOSE/OBJECTIVES: This paper examines how cigarillo smokers self-identify in terms of addiction and the association of this identification with tobacco use, quitting experiences, and level of nicotine dependence. METHODS: Transcripts from semi-structured interviews conducted in 2015-2016 with 57 participants (aged 14-28) about cigarillo use and beliefs were analyzed using a phenomenological approach to examine themes around addiction and cessation experiences. Analyses were limited to participants endorsing having a habit. Quantitative analyses were conducted to assess associations with demographics, tobacco use, addiction, cessation, and nicotine dependence for two groups: participants endorsing having an addiction to cigarillos and those who did not. RESULTS: All participants described the term addiction similarly. Participants with an addiction had significantly higher nicotine dependence and self-rating of addiction than those without an addiction. Although most quitting experiences did not differ between the two groups, participants who did not identify as addicted felt that they could quit smoking cigarillos at any time. CONCLUSIONS: Variations in identification with addiction are not associated with differences in definitions, use and quit experiences. Understanding self-perceptions of addiction can inform targeted communication to encourage cessation and the use of cessation resources.

Effectiveness of Social Media Approaches to Recruiting Young Adult Cigarillo Smokers: Cross-Sectional Study.

BACKGROUND: The prevalence of social media use among youth and young adults suggests it is an appropriate platform for study recruitment from this population. Previous studies have examined the use of social media for recruitment, but few have compared platforms, and none, to our knowledge, have attempted to recruit cigarillo users. OBJECTIVE: The purpose of this study was to examine the effectiveness of different social media platforms and advertisement images for recruiting cigarillo users aged 14-28 years to complete a cigarillo use survey. METHODS: We obtained objective data for advertisement impressions for a 39-week social media recruitment campaign. Advertisements were targeted to users based on their age, geography, and interests. Effectiveness was defined as the percentage of approved surveys per advertising impression. Chi-square tests were performed to compare the effectiveness of different advertisement images and platforms. RESULTS: Valid survey completers (n=1089) were predominately older (25-28 years old, n=839, 77%). Of the 1089 survey completers, 568 (52%) identified as male, 335 (31%) as African American, and 196 (18%) as Hispanic. Advertisements delivered via Facebook/Instagram were more effective than Twitter; 311/1,027,738 (0.03%) vs 661/2,998,715 (0.02%); χ21=21.45, N=4,026,453); P<.001. Across platforms, ads featuring exclusively an image of cigarillos were more effective (397/682,994, 0.06%) than ads with images of individuals smoking (254/1,308,675, 0.02%), individuals not smoking (239/1,393,134, .02%), and groups not smoking (82/641,650, 0.01%); χ23133.73, N=4,026,453; P<.001. CONCLUSIONS: The campaign was effective in recruiting a diverse sample representative of relevant racial/ethnic categories. Advertisements on Facebook were more effective than Twitter. Advertisements that featured an image of a cigarillo were consistently the most effective and should be considered by others recruiting cigarillo users via social media.

Cigarettes, Little Cigars, and Cigarillos: Initiation, Motivation, and Decision-Making.

Introduction: Cigarettes and little cigars and cigarillos (LCCs) are the most prevalent dual-use tobacco combination; one-third of cigarette smokers use LCCs. Risk factors for multiple tobacco product use have been reported; however, there is little understanding of why some individuals transition to and maintain multiple product use. In this study, we examine narratives of tobacco product initiation and decision-making among LCC-only and LCC-cigarette smokers. Methods: We audio-recorded in-depth interviews with 60 individuals, aged 14-28, who reported smoking more than or equal to 1 cigarillo per week; half also smoked cigarettes. Transcribed interviews were coded using a phenomenological approach to examine themes about smoking initiation, motivation, and product decision-making. Results: Among dual users, 60% began smoking LCCs before or at the same time as cigarettes, and 40% began smoking cigarettes first. Reasons for smoking cigarettes in addition to LCCs included easier access when experiencing craving and less time to smoke the product. Cigarette smokers reported first smoking LCCs in social contexts when sharing LCCs with other smokers, or when they could afford a single LCC but not a pack of cigarettes. LCC-only smokers reported not smoking cigarettes because of their expense, unpleasant taste and/or smell, and fear of becoming addicted. Conclusions: In this sample of current LCC users, half also used cigarettes. Product initiation order was almost evenly split, but reasons for initiating the second product differed, with immediacy of reducing cravings as a key reason for LCC users to smoke a cigarette and social and financial reasons for cigarette users to smoke an LCC. Implications: Understanding how and why dual use is initiated and sustained can inform policies to help prevent increased nicotine dependence and initiation of additional tobacco products. This study demonstrates that the beliefs, perceptions, and practices of LCC-only and dual users inform their product selection. Our findings point to the need to apply the strategies that have been effective at decreasing cigarette consumption to LCCs.

The Social Context of Adolescent Co-Use of Cigarillos and Marijuana Blunts.

BACKGROUND: The use of cigarillos for smoking as a tobacco product and for making marijuana blunts is increasing among adolescents. Previous research has documented the co-use of these products, however little is known about the contextual features that generate and sustain this practice. OBJECTIVE: This study aims for a deeper understanding of why and how co-use of cigarillos and marijuana blunts occurs. METHODS: Between December 2015 and April 2016, we conducted in-depth interviews with 30 adolescents aged 14-18 who reported smoking ≥1 cigarillo per week. Semi-structured interviews were designed to capture participants' smoking products, practices, and preferences, as well as their beliefs and experiences about smoking. Interviews were audio-recorded and transcribed. Analysis was guided by a phenomenological approach designed to identify emergent themes. RESULTS: All participants reported smoking cigarillos for use as a tobacco product, averaging 13 per week. Twenty-five (83%) also reported using cigarillos to smoke marijuana blunts. A preference for group smoking and product sharing, and the belief that cigarillos extend the high of marijuana were found to promote the co-use of these products. Cigarillos were also found to be used as a substitute for blunts when marijuana was unavailable or when its use was being restricted or monitored. Conclusions/Importance: This analysis of adolescent cigarillo and marijuana co-use demonstrates how marijuana use can initiate, increase, and reinforce tobacco use. These findings can be used to inform public health education campaigns and other programs and policies aimed at reducing cigarillo and marijuana use by youth.

Understanding Nicotine Dependence and Addiction Among Young Adults Who Smoke Cigarillos: A Qualitative Study.

Introduction: Cigarillo use is increasing, particularly among young adults. Nicotine dependence (ND) is important for understanding smoking behavior and cessation, but the development of measures of ND has focused almost exclusively on cigarette smokers. We examined smoking patterns, preferences, and beliefs of cigarillo users to better understand their experience of addiction and expression of ND symptoms. Methods: Using purposive sampling, we conducted in-depth interviews between June 2015 and January 2016 with 30 young adults aged 18-28 who reported smoking ≥1 cigarillo per week. Interviews were based on a semi-structured guide designed to capture participants' smoking levels and patterns as well as their experiences of smoking and addiction. Interviews were audio-recorded and transcribed. Analysis was guided by a phenomenological approach designed to identify emergent themes. Results: Participants had a mean age of 23, with a majority being female (56%) and African American (80%). The median number of cigarillos smoked per week was 20; 70% also smoked cigarettes, and 43% also smoked marijuana blunts. Our analysis highlighted the complexity of measuring cigarillo use due to product manipulation, sharing, and multiple product use. Participants expressed a preference for smoking in a social group where cigarillos were shared, and not smoking an entire cigarillo at once when alone. Most cigarillo users did not consider themselves to be addicted. Conclusions: Cigarillo users express unique smoking practices and beliefs that signify the need for a more product-inclusive measure of ND, and can inform the development of tobacco cessation interventions tailored to cigarillo users. Implications: The increasing use of cigarillos among young adults has significant public health consequences. Addressing this issue requires accurate measurement and effective treatment of dependence on cigarillo products. The results of this study directly inform the development of a revised measure of ND, and can contribute to the efficacy of cessation interventions for cigarillo users.

Cancer prevention and control interventions using social media: user-generated approaches.

Social media are now used by a majority of American internet users. Social media platforms encourage participants to share information with their online social connections and exchange user-generated content. Significant numbers of people are already using social media to share health-related information. As such, social media provide an opportunity for "user-generated" cancer control and prevention interventions that employ users' behavior, knowledge, and existing social networks for the creation and dissemination of interventions. These interventions also enable novel data collection techniques and research designs that will allow investigators to examine real-time behavioral responses to interventions. Emerging social media-based interventions for modifying cancer-related behaviors have been applied to such domains as tobacco use, diet, physical activity, and sexual practices, and several examples are discussed for illustration purposes. Despite some promising early findings, challenges including inadequate user engagement, privacy concerns, and lack of internet access among some groups need to be addressed in future research. Recommendations for advancing the field include stronger partnerships with commercial technology companies, utilization of rapid and adaptive designs to identify successful strategies for user engagement, rigorous and iterative efficacy testing of these strategies, and inclusive methods for intervention dissemination.
