Results of a Feasibility and Acceptability Trial of an Online Smoking Cessation Program Targeting Young Adult Nondaily Smokers

Despite increases in nondaily smoking among young adults, no prior research has aimed to develop and test an intervention targeting this group. Thus, we aimed to develop and test the feasibility, acceptability, and potential effectiveness of an online intervention targeting college student nondaily smokers. We conducted a one-arm feasibility and acceptability trial of a four-week online intervention with weekly contacts among 31 college student nondaily smokers. We conducted assessments at baseline (B), end of treatment (EOT), and six-week followup (FU). We maintained a 100% retention rate over the 10-week period. Google Analytics data indicated positive utilization results, and 71.0% were satisfied with the program. There were increases (P < .001) in the number of people refraining from smoking for the past 30 days and reducing their smoking from B to EOT and to FU, with additional individuals reporting being quit despite recent smoking. Participants also increased in their perceptions of how bothersome secondhand smoke is to others (P < .05); however, no other attitudinal variables were altered. Thus, this intervention demonstrated feasibility, acceptability, and potential effectiveness among college-aged nondaily smokers. Additional research is needed to understand how nondaily smokers define cessation, improve measures for cessation, and examine theoretical constructs related to smoking among this population.

Perceived Harm, Addictiveness, and Social Acceptability of Tobacco Products and Marijuana Among Young Adults: Marijuana, Hookah, and Electronic Cigarettes Win

Background: There has been an increase in non-daily smoking, alternative tobacco product and marijuana use among young adults in recent years. Objectives: This study examined perceptions of health risks, addictiveness, and social acceptability of cigarettes, cigar products, smokeless tobacco, hookah, electronic cigarettes, and marijuana among young adults and correlates of such perceptions. Methods: In Spring 2013, 10,000 students at two universities in the Southeastern United States were recruited to complete an online survey (2,002 respondents), assessing personal, parental, and peer use of each product; and perceptions of health risks, addictiveness, and social acceptability of each of these products. Results: Marijuana was the most commonly used product in the past month (19.2%), with hookah being the second most commonly used (16.4%). The least commonly used were smokeless tobacco products (2.6%) and electronic cigarettes (4.5%). There were high rates of concurrent product use, particularly among electronic cigarette users. The most positively perceived was marijuana, with hookah and electronic cigarettes being second. While tobacco use and related social factors, related positively, influenced perceptions of marijuana, marijuana use and related social factors were not associated with perceptions of any tobacco product. Conclusions/Importance: Marketing efforts to promote electronic cigarettes and hookah to be safe and socially acceptable seem to be effective, while policy changes seem to be altering perceptions of marijuana and related social norms. Research is needed to document the health risks and addictive nature of emerging tobacco products and marijuana and evaluate efforts to communicate such risks to youth.

Smoker self-identification versus recent smoking among college students.

BACKGROUND College students who engage in occasional or social cigarette smoking are less likely to identify themselves as smokers and to attempt to quit. This analysis aimed to determine: (1) the correlates of denying being a smoker among students reporting smoking in the past 30 days and (2) if denying this label was related to not attempting to quit smoking in the past 12 months. METHODS A total of 9931 students at 14 colleges completed a random sample survey in 2007. RESULTS Of 2255 students reporting having smoked a cigarette in the past 30 days, 50.7% responded No to Do you consider yourself a smoker. Logistic regression indicated that, after controlling for the number of smoking days in the past 30, being younger (OR=0.94, p<0.001); being male (OR=1.59, p=0.009); attending a 4-year (versus 2-year) college (OR=1.73, p=0.004); and consuming alcohol in the previous 30 days (OR=2.14, p=0.03) were correlates of denying being a smoker. Logistic regression indicated that denial was related to not attempting to quit in the past 12 months (OR=1.72, p<0.001), after controlling for the number of smoking days, age, gender, type of school, and other health factors. CONCLUSIONS Half of college smokers deny being smokers, particularly those who are younger, male, attending 4-year colleges, and alcohol consumers. Denying being a smoker was associated with not attempting to quit smoking. Therefore, traditional methods of ascertaining smoking status may not be valid in this population. Healthcare providers should more specifically ask students about recent smoking behavior. Further research is needed to develop interventions targeting smoking among this population.

Utilization of Smoking Cessation Informational, Interactive, and Online Community Resources as Predictors of Abstinence: Cohort Study

Background The association between greater utilization of Web-assisted tobacco interventions and increased abstinence rates is well recognized. However, there is little information on how utilization of specific website features influences quitting. Objective To determine the association between utilization of informational, interactive, and online community resources (eg. bulletin boards) and abstinence rates, with the broader objective to identify potential strategies for improving outcomes for Web-assisted tobacco interventions. Methods In Spring 2004, a cohort of 607 quitplan.com users consented to participate in an evaluation of quitplan.com, a Minnesota branded version of QuitNet.com. We developed utilization measures for different site features: general information, interactive diagnostic tools and quit planning tools, online expert counseling, passive (ie, reading of bulletin boards) and active (ie, public posting) online community engagement, and one-to-one messaging with other virtual community members. Using bivariate, multivariate, and path analyses, we examined the relationship between utilization of specific site features and 30-day abstinence at 6 months. Results The most commonly used resources were the interactive quit planning tools (used by 77% of site users). Other informational resources (ie, quitting guides) were used more commonly (60% of users) than passive (38%) or active (24%) community features. Online community engagement through one-to-one messaging was low (11%) as was use of online counseling (5%). The 30-day abstinence rate among study participants at 6 months was 9.7% (95% Confidence Interval [CI] 7.3% - 12.1%). In the logistic regression model, neither the demographic data (eg, age, gender, education level, employment, or insurance status) nor the smoking-related data (eg, cigarettes per day, time to first morning cigarette, baseline readiness to quit) nor use of smoking cessation medications entered the model as significant predictors of abstinence. Individuals who used the interactive quit planning tools once, two to three times, or four or more times had an odds of abstinence of 0.65 (95% Confidence Interval [CI] 0.22 - 1.94), 1.87 (95% CI 0.77 - 4.56), and 2.35 (95% CI 1.0 - 5.58), respectively. The use of one-to-one messages (reference = none vs 1 or more) entered the final model as potential predictor for abstinence, though the significance of this measure was marginal (OR = 1.91, 95% CI 0.92 - 3.97, P = .083). In the path analysis, an apparent association between active online community engagement and abstinence was accounted for in large part by increased use of interactive quitting tools and one-to-one messaging. Conclusions Use of interactive quitting tools, and perhaps one-to-one messaging with other members of the online community, was associated with increased abstinence rates among quitplan.com users. Designs that facilitate use of these features should be considered.

Failure to report attempts to quit smoking

INTRODUCTION Accurately assessing quit attempt history is important to develop population estimates of cessation and to increase our understanding of smoking trajectories. Thus, the current study investigated failure to report quit attempts as a function of length of quit attempt by time since quit attempt over the past year. METHODS The present study used data from the Smoking Toolkit Study, a series of population-based surveys of smokers and recent ex-smokers in England aged 16 years and older. Among the 11,772 smokers identified at baseline (24.4% of the total sample), this study focused on the 4234 participants (36.0% of current smokers) who reported between one and three quit attempts in the past year. RESULTS There was a strong trend for quit attempts that lasted for shorter periods of time to fail to be reported. After three months, 90.1% of those lasting less than one day, 63.7% of those lasting between a day a one week, and 38.9% of those lasting between one week and one month failed to be reported. CONCLUSION A large proportion of unsuccessful quit attempts fail to be reported, particularly if they only last a short time or occurred longer ago. Therefore, population estimates of quit attempts based on retrospective data may be considerable underestimates and estimates of the success of quit attempts may be overestimates. Future research is needed to establish whether there is differential reporting of quit attempts as a function of features of attempts such as use of cessation aids.

Assessing the overlap between tobacco and marijuana: Trends in patterns of co-use of tobacco and marijuana in adults from 2003–2012

BACKGROUND As marijuana legalization and acceptability increase in the U.S., it is important to understand the potential impact on tobacco use. Accordingly, we assessed prevalence, correlates, and ten-year trends in co-use of marijuana and tobacco among U.S. adults. METHODS Data came from 378,459 adults participating in the 2003-2012 National Survey on Drug Use and Health, an annual, cross-sectional, household survey. Data from 2011-2012 were used to compute the most recent prevalence of past 30-day marijuana and tobacco use (co-use). Data from 2003-2012 were used to compute demographic correlates of co-use, overall trends in co-use, and trends by age, race, and sex. We also assessed trends in tobacco use among marijuana users and marijuana use among tobacco users. RESULTS From 2011 to 2012, 5.2% of participants were past month co-marijuana and tobacco users, 24.0% were tobacco-only users, and 2.3% were marijuana-only users. From 2003 to 2012, prevalence of co-use increased overall (p<.0001), and among males and females (p<.001, p<.05), those ages 26-34 (p<.001) and 50+years (p<.0001), and Whites (p<.01), Blacks (p<.05), and Hispanics (p<.01); there were no changes among adults 18-25 years. Tobacco use among marijuana users decreased between 2003 and 2012 (from 74.3% to 69.6%, p<.0001), while marijuana use increased among tobacco users (from 14.2% to 17.8, p<.0001). CONCLUSIONS Co-use of tobacco and marijuana increased from 2003-2012, with marijuana use increasing among past-month tobacco users and tobacco use declining among past-month marijuana users. Improved surveillance of co-use is needed as marijuana legalization policies expand and become more integrated in communities.

The Effectiveness of a Hope Intervention in Coping with Cold Pressor Pain

Hope has been correlated with greater pain tolerance and thresholds and less reported pain severity. The present study investigated the effectiveness of a brief hope-based intervention involving guided imagery and skills instruction aimed at enhancing pain coping skills among university students performing the cold pressor task. The intervention resulted in increased hope among females and increased pain tolerance in all participants. The intervention did not affect pain threshold and resulted in marginally increased pain severity. Thus, this intervention facilitates better pain tolerance without necessarily changing the experience of the pain. Implications for practice and future research are discussed.

The relationship of children's hope to pediatric asthma treatment adherence

This study investigated the relationship between hope and adherence to a daily inhaled steroid regimen among 48 asthma patients ages 8–12 years old who participated in a 14 day adherence assessment. Participants completed the Childrens Hope Scale, and parents completed a questionnaire aimed at demographic and disease-related information. Adherence was measured by electronic monitoring of the use of the participants metered-dose inhaler. A multivariate model predicting nonadherence was built, including FEV1 in the first step and childrens hope level in the second step. This model was a significant predictor of adherence (Nagelkerke R 2 = 0.24, p = 0.01). No other demographic or psychosocial variables were significant predictors of adherence. These findings highlight the need to attend to psychosocial predictors of adherence, specifically hope, and may help practitioners target these factors in their efforts to increase adherence among pediatric asthma patients.

Attitudes toward E-Cigarettes, Reasons for Initiating E-Cigarette Use, and Changes in Smoking Behavior after Initiation: A Pilot Longitudinal Study of Regular Cigarette Smokers

Objectives We examined 1) changes in smoking and vaping behavior and associated cotinine levels and health status among regular smokers who were first-time e-cigarette purchasers and 2) attitudes, intentions, and restrictions regarding e-cigarettes. Methods We conducted a pilot longitudinal study with assessments of the aforementioned factors and salivary cotinine at weeks 0, 4, and 8. Eligibility criteria included being ≥18 years old, smoking ≥25 of the last 30 days, smoking ≥5 cigarettes per day (cpd), smoking regularly ≥1 year, and not having started using e-cigarettes. Of 72 individuals screened, 40 consented, 36 completed the baseline survey, and 83.3% and 72.2% were retained at weeks 4 and 8, respectively. Results Participants reduced cigarette consumption from baseline to week 4 and 8 (p’s < 0.001); 23.1% reported no cigarette use in the past month at week 8. There was no significant decrease in cotinine from baseline to week 4 or 8 (p’s = ns). At week 8, the majority reported improved health (65.4%), reduced smoker’s cough (57.7%), and improved sense of smell (53.8%) and taste (50.0%). The majority believed that e-cigarettes versus regular cigarettes have fewer health risks (97.2%) and that e-cigarettes have been shown to help smokers quit (80.6%) and reduce cigarette consumption (97.2%). In addition, the majority intended to use e-cigarettes as a complete replacement for regular cigarettes (69.4%) and reported no restriction on e-cigarette use in the home (63.9%) or car (80.6%). Conclusions Future research is needed to document the long-term impact on smoking behavior and health among cigarette smokers who initiate use of e-cigarettes.

Tobacco Use by College Students: A Comparison of Daily and Nondaily Smokers

OBJECTIVES To explore demographics, contextual factors, and health risk behaviors associated with nondaily smoking by college students. METHODS In fall 2005, a random sample of 4100 students completed an online survey. RESULTS Of those surveyed, 29% reported current smoking; of that 29%, 70% were nondaily smokers. Compared to daily smokers, nondaily smokers were younger, African American (compared to white), had mothers with higher education, belonged to Greek organizations, and attended private (vs public) schools. Nondaily smokers were less likely to have used illicit drugs. CONCLUSIONS Nondaily and daily smokers differed on several demographic and contextual factors, but reported mostly similar health risk behaviors.
