Smoking reduction using an electronic nicotine delivery system (ENDS) with nicotine delivery similar to combustible cigarettes

BackgroundElectronic nicotine delivery systems (ENDS) offer a promising approach to tobacco harm reduction, but many people use both ENDS and combustible cigarettes (“dual use”), which undermines potential risk reduction. To explore the role of ENDS nicotine delivery in promoting switching to ENDS, we conducted a study in which people who smoked cigarettes were offered an ENDS that had previously been shown to replicate the rapid nicotine pharmacokinetics of combustible cigarettes (BIDI® Stick).MethodsTwenty-five cigarette smoking adults, not seeking smoking cessation treatment, but open to using ENDS as a cigarette substitute, were provided with a 12-week supply of BIDI® Stick in tobacco or menthol flavors, during a study that included seven biweekly sessions and a 6-month follow-up. Daily diaries assessed ENDS and cigarette use, and exhaled carbon monoxide (eCO) served as an objective marker of smoke intake. Subjective ratings were collected to assess the rewarding properties of ENDS and combustible cigarettes, and indices of nicotine dependence.ResultsOver 12 weeks, ENDS use increased to an average of 15.8 occasions per day (SD = 20.2) and self-reported cigarette consumption decreased by 82% from 16.7 cigarettes/day (SD = 6.0) at baseline to 3.0 cigarettes/day (SD = 4.1) at week 12. The eCO level decreased by 27% from an average of 20.0 ppm (SD = 9.8) at baseline to 14.5 ppm (SD = 9.9) at week 12. Four of 25 participants completely switched to ENDS and were smoking abstinent during weeks 9–12. At 6 months one participant was confirmed to be abstinent. Ratings of subjective reward for the ENDS were very similar to those of participants’ usual brands of cigarettes. Dependence level was lower for the ENDS than for combustible cigarettes.ConclusionsIn this study, the ENDS effectively replicated the subjective rewarding effects of participants’ usual brands of cigarettes and led to a substantial reduction in reported cigarettes/day. Exhaled CO showed less of a decrease, possibly due to compensatory smoking behavior and/or the timing of eCO measurements that might not have reflected smoke intake throughout the day. The relatively low rate of sustained smoking abstinence at 6 months suggests that additional approaches continue to be needed for achieving higher rates of complete switching.Trial registrationClinicalTrials.gov identifier NCT05855343.

Cognitive Distortions as Barriers to Seeking Smoking Cessation Treatment: A Comparative Study.

Background/Objectives: Despite the availability of effective pharmacotherapy and evidence-based treatments, a substantial proportion of smokers do not seek treatment. This study aims to explore the cognitive distortions associated with not seeking evidence-based smoking cessation treatment and to identify cognitive barriers. Methods: The research conducted in Istanbul between October and December 2017 employs a cross-sectional design and includes two groups: a treatment-seeking group comprising 156 patients diagnosed with tobacco use disorder and a non-treatment seeking group of 78 patients with tobacco use disorder who had never sought professional help for smoking cessation. A comprehensive data collection process was used, including sociodemographic information, cognitive distortion assessment using the cognitive distortions scale, a smoking-related cognitive distortions interview and the Fagerström Test for Nicotine Dependence. Results: While no significant sociodemographic differences were observed between the treatment-seeking and non-treatment-seeking groups, the study found that higher nicotine dependence was associated with a higher likelihood of seeking treatment. The treatment-seeking group displayed significantly higher levels of "all-or-nothing thinking" cognitive distortions related to smoking and smoking cessation. Conversely, the non-treatment-seeking group exhibited elevated levels of cognitive distortions such as "labeling", "mental filtering", "should statements" and "minimizing the positive" regarding receiving smoking cessation treatment. Conclusions: Understanding the cognitive distortions associated with treatment-seeking behavior for tobacco use disorder is crucial for developing targeted public-based interventions, public service announcements for tobacco use prevention and encouraging individuals to seek evidence-based treatment. Addressing these cognitive distortions can also potentially enhance the effectiveness of smoking cessation programs and reduce the global burden of tobacco-related diseases and mortality.

Comparing the Fagerström Test and Heaviness of Smoking Index in Predicting Smoking Abstinence in Cancer Patients.

People with cancer who smoke exhibit greater cigarette dependence than people without cancer who smoke, a crucial factor in smoking cessation. Research is limited on the predictive potential of the Fagerström Test for Cigarette Dependence (FTCD) and the Heaviness of Smoking Index (HSI) on smoking abstinence in cancer patients undergoing smoking cessation treatment. We analyzed data from 5934 cancer patients seeking smoking cessation treatment at The University of Texas MD Anderson Cancer Center (female 52.08%; Mean age = 55.52, SD = 11.17). We evaluated the predictive accuracy of FTCD and HSI on abstinence at 3, 6, and 9 months from the first consultation, and assessed the concordance between these tools in measuring cigarette dependence using Cohen's kappa test and different correlation and regression models. We also analyzed variations across sex at birth and race/ethnicity. Both the FTCD and the HSI demonstrated comparable predictive accuracy for smoking cessation at all follow-ups, with neither showing high accuracy (Areas Under the Curve scores around 0.6). Concordance analysis revealed substantial agreement between FTCD and HSI scores (Cohen's kappa ~ 0.7), particularly at lower levels of dependence. However, this agreement varied by race, with reduced concordance observed in non-Hispanic Blacks. Our results indicate that both the FTCD and HSI are effective tools for predicting smoking cessation in cancer patients, with the HSI offering a less burdensome assessment option. Nevertheless, the findings suggest the need for tailored approaches in assessing cigarette dependence that could predict smoking cessation more accurately, considering racial differences. The burden of assessing cigarette dependence in cancer care settings can be reduced by using the HSI instead of the FTCD. In addition, both instruments could be substantially interchanged and used for meta-analytic studies examining dependence and abstinence, but race/ethnicity should be considered.

Correlates of e-cigarette use among adults initiating smoking cessation treatment

BackgroundLittle is known about the correlates of e-cigarette (EC) use among adults seeking smoking cessation treatment, and it is unclear how EC use affects smoking treatment outcomes. MethodsParticipants were 649 adult smokers enrolled in smoking cessation treatment. Participants completed a baseline (pre-quit) assessment with follow-up at 4-, 12-, and 26-weeks after a scheduled combustible cigarette (CC) cessation date. EC use was described before and after the CC cessation date, and the impact of baseline EC use on CC cessation at follow-up was evaluated. ResultsAt baseline, 66.6 % of participants had ever-used ECs and 23.1 % reported past 30-day EC use. Past 30-day EC users were younger, more socioeconomically disadvantaged, more CC dependent, and less likely to report Black race compared to non-users. At the 4-, 12-, and 26-week follow-ups, 6.4 %, 7.4 %, and 8.1 % reported dual EC/CC use; and 2.7 %, 3.4 %, and 2.7 % had switched to exclusive EC use. Past 30-day EC use at baseline was not associated with CC cessation at any follow-up. However, among baseline past 30-day EC users (n = 150), using ECs ≥ once per week was associated with a lower likelihood of CC cessation at 26-week follow-up (adjusted OR 0.346, 95 % CI: 0.120, 0.997). ConclusionFindings indicated that dual users of CCs and ECs at baseline differed from CC-only users on sociodemographic and smoking characteristics. Baseline EC use did not impact smoking cessation overall. However, among past 30-day users, more frequent EC use at baseline adversely impacted longer-term cessation outcomes, perhaps due to greater baseline CC/nicotine dependence.

Is cannabis use associated with tobacco cessation outcome? An observational cohort study in primary care

BackgroundSome studies suggest cannabis use negatively affects tobacco cessation outcomes, but findings have been mixed. We examined whether cannabis use was associated with tobacco cessation outcomes in a real-world primary care setting. MethodsThe analytic dataset consisted of 35,246 patients who enrolled between 2014 and 2016 in a primary care-based smoking cessation program in Ontario, Canada. Past 30-day cannabis use, for recreational or medical purposes, was self-reported at enrollment. Thirty-day point prevalence tobacco smoking abstinence was self-reported via online or telephone survey at 6 months post-enrollment. ResultsThirty days prior to enrollment, 79.9 % of patients had not used cannabis, 16.3 % used cannabis for recreational purposes only, and 3.8 % used cannabis for medical purposes. Unadjusted and adjusted odds of tobacco cessation at 6 months were reduced for patients using cannabis compared to non-users (ORs = 0.76-0.86, ps<0.05). When cannabis use was categorized by purpose, both unadjusted and adjusted odds of cessation were significantly lower for recreational users (ORs = 0.77-0.84, ps<0.05). Medical users had decreased odds of cessation in unadjusted analysis (OR = 0.74, 95 % CI = 0.61-0.89, p = 0.001), but not after adjustment for potential confounders. However, post-estimation contrasts did not indicate a significant difference between the effect of recreational and medical cannabis use. ConclusionsIn a large real-world sample of patients seeking smoking cessation treatment, concurrent cannabis use was associated with decreased success with quitting smoking. Recreational cannabis use was consistently related to poorer cessation outcomes, but medical use was not. Additional research is needed to inform treatment strategies for this growing sub-population of smokers.

A pilot study to examine the acceptability and health effects of electronic cigarettes in HIV-positive smokers

IntroductionSome HIV-positive smokers report ambivalence about quitting. Switching to electronic cigarettes (ECs) may be a viable option to reduce the negative health effects for smokers who are unable or unwilling to quit smoking combustible cigarettes (CCs). This study examined the acceptability and health-related effects of ECs in HIV-positive smokers who were not seeking smoking cessation treatment. MethodsHIV-positive smokers (N = 19) were enrolled and followed for 12 weeks. Cartridge-based ECs were provided at baseline, and E-liquid was provided weekly for 8 weeks. At baseline, weeks 1–8, and week 12, EC and CC use, cardiopulmonary function, respiratory symptoms, and carbon monoxide (CO) levels were measured. ResultsAt week 8, cigarettes per day (CPD) were reduced by more than 80%, with reduction maintained at week 12 (p’s < .001). Cigarette dependence scores were 40% lower at week 8 than at baseline (p < .001). Seven (36.8%) participants reported transitioning completely from CCs to ECs. Mean CO decreased significantly from BL to week 8 (p < .05) and remained significantly lower at week 12 (p < .001). Intention to quit increased significantly over time. ConclusionsSwitching from CCs to ECs in HIV-positive smokers who are not ready to quit smoking in the next 30 days appears to be feasible. Beneficial effects were seen, such as reduced CPD, reduced CO and CC dependence, and increased motivation to quit. ECs may be promising as a harm reduction approach among HIV-positive smokers who are unable or unwilling to quit smoking.

Lifetime Depression, Other Mental Illness, and Smoking Cessation.

Objectives In this study, we attempt to elucidate the relationship between lifetime mental illness (LMI), particularly a depression diagnosis, and smoking cessation. Methods Data were drawn from a previous study and include LMI, demographics, mood, and smoking cessation outcomes. We evaluated the relationship between multiple LMIs and smoking cessation at 7 months post-intervention, and depression in combination with another LMI. Results At 7 months, the adjusted odds of cessation for those with one LMI, including depression, were 0.74 (p = .102), and for those with 2+ LMIs, 0.69 (p = .037), both in comparison with participants who reported no history of LMI. Among those with 2+ LMIs, the adjusted odds of cessation for those with a depression diagnosis were 0.34 (p = .007) compared to those whose multiple LMIs did not include depression. Conclusions Among smokers seeking cessation treatment, those who had 2+ LMIs were at greater risk of relapse, an effect particularly marked in smokers with depression. This study adds to the literature examining the potential impact of LMI on smokers' ability to quit by considering the potential impact of 2+ LMIs and highlights the potential impact of depression as a risk factor for continued smoking.

Association between smoking cessation and weight gain in treatment-seeking African Americans

IntroductionResearch has shown that African Americans gain more than average weight after smoking cessation. However, African Americans have been underrepresented in post-cessation weight gain research. The current study examined 1) the pattern of weight gain and 2) the association between smoking status and weight gain in a sample of African Americans seeking smoking cessation treatment. MethodsData were drawn from a randomized controlled trial testing the efficacy of a 4-week culturally specific smoking cessation cognitive behavioral therapy (CBT) intervention among African American smokers (N = 342). Weight was measured and self-reported smoking status was biochemically verified at baseline, end of counseling, 3-, 6-, and 12-month follow-ups. Random effects multilevel modeling was used to examine weight gain over twelve months post CBT, and a fully unconditional model tested the pattern of weight gain over time. Smoking status was included as a time-varying factor to examine its effect on weight gain, controlling for potential confounding variables. ResultsWeight significantly increased among those who remained abstinent over 12 months post CBT [average gain of seven lbs. (three kg)]. Controlling for covariates, abstinence was predictive of the rate of weight gain for those with high weight concern. ConclusionsWeight gain among African American abstainers was comparable to the average post-cessation weight gain observed among the general population. It is possible that exposure to CBT (culturally specific or standard) may have mitigated excessive weight gain. Future research should assess predictors of weight gain in African American smokers to inform future smoking cessation interventions and help elucidate factors that contribute to tobacco- and obesity-related health disparities.

Types of Smokers Who Seek Smoking Cessation Treatment According to Psychopathology

ABSTRACTPsychopathology and psychological distress have been shown to be related to poor smoking cessation outcomes and abstinence maintenance. Thus, it is important to identify individuals with high levels of psychopathology before undergoing smoking cessation treatment in order to increase their likelihood of success. Objective: The primary aim of the present study was to analyze whether we could classify smokers by using self-reported measures of psychopathology. In addition, a secondary aim was to examine if there were significant differences among the groups of smokers regarding sociodemographic information, nicotine dependence, and cessation rates at the end of treatment and at 6- and 12-month follow-ups. Methods: Participants were 281 smokers seeking smoking cessation treatment. Participants were classified into different smoking groups by using a 2-step cluster analysis based on baseline scores on the Restructured Clinical (RC) scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), Beck Depression Inventory-II (BDI-II), and State-Trait Anxiety Inventory (STAI). Results: Smokers were classified into 3 groups according to levels of psychopathology: Low (n = 158), Intermediate (n = 78), and High (n = 45). Smokers in the High Group were more likely to present higher levels of psychopathology and to continue smoking at the end of treatment when compared with the two other clusters. In addition, smokers classified in this group were more likely to be nicotine dependent and from a low social class. Conclusions: A subgroup of smokers can be easily identified through self-report measures of psychopathology. Furthermore, these individuals were more likely to continue smoking at the end of treatment. This suggests that this group with high levels of psychopathology might benefit from future interventions that are more intensive or cessation treatments targeted to their specific characteristics.

A Double-Blind Randomized Placebo-Controlled Trial of Oral Naltrexone for Heavy-Drinking Smokers Seeking Smoking Cessation Treatment.

Post hoc analyses of 2 randomized controlled trials suggest naltrexone may reduce alcohol use and improve smoking cessation outcomes among heavy drinkers receiving smoking cessation treatment. However, no studies have been conducted specifically to examine naltrexone for this purpose or to test whether naltrexone has benefit when added to smoking cessation counseling that explicitly addresses heavy drinking. We recruited heavy-drinking smokers from the community and randomized them to receive 10weeks of either (i) 50mg naltrexone (n=75) or (ii) placebo (n=75) daily. Participants received 6weeks of transdermal nicotine patch and 6 sessions of counseling that addressed both heavy drinking and smoking. Participants were followed for 26weeks after their target quit smoking date. Across medication conditions, there were substantial reductions at follow-up in percent heavy drinking days (primary outcome) and average drinks per week (secondary outcome). However, participants receiving naltrexone did not differ significantly from those receiving placebo on percent heavy drinking days (effect size d=-0.04, 95% CI [-0.30, 0.22], p=0.76) or average drinks per week (d=-0.09, 95% CI [-0.35, 0.18], p=0.54) during follow-up. Naltrexone compared to placebo was not associated with a significant increase in smoking abstinence rates during follow-up, odds ratio=0.93, 95% CI [0.46, 1.86], p=0.83. The effect of naltrexone on these outcomes was not significantly moderated by current alcohol dependence or gender. Results indicate that heavy-drinking smokers, including those with current alcohol dependence, can make substantial reductions in drinking in the context of smoking cessation treatment. However, this study provided no evidence that naltrexone is efficacious for enhancing reductions in drinking or improving smoking cessation in this population. Limitations of this study included lower-than-desired sample size and modest adherence to study medication.

An Ecological Momentary Intervention for Smoking Cessation: Evaluation of Feasibility and Effectiveness.

BackgroundDespite substantial public health progress in reducing the prevalence of smoking in the United States overall, smoking among socioeconomically disadvantaged adults remains high.ObjectiveTo determine the feasibility and preliminary effectiveness of a novel smartphone-based smoking cessation app designed for socioeconomically disadvantaged smokers.MethodsParticipants were recruited from a safety-net hospital smoking cessation clinic in Dallas, Texas, and were followed for 13 weeks. All participants received standard smoking cessation clinic care (ie, group counseling and cessation pharmacotherapy) and a smartphone with a novel smoking cessation app (ie, Smart-T). The Smart-T app prompted 5 daily ecological momentary assessments (EMAs) for 3 weeks (ie, 1 week before cessation and 2 weeks after cessation). During the precessation period, EMAs were followed by messages that focused on planning and preparing for the quit attempt. During the postcessation period, participant responses to EMAs drove an algorithm that tailored messages to the current level of smoking lapse risk and currently present lapse triggers (eg, urge to smoke, stress). Smart-T offered additional intervention features on demand (eg, one-click access to the tobacco cessation quitline; “Quit Tips” on coping with urges to smoke, mood, and stress).ResultsParticipants (N=59) were 52.0 (SD 7.0) years old, 54% (32/59) female, and 53% (31/59) African American, and 70% (40/57) had annual household income less than US $16,000. Participants smoked 20.3 (SD 11.6) cigarettes per day and had been smoking for 31.6 (SD 10.9) years. Twelve weeks after the scheduled quit date, 20% (12/59) of all participants were biochemically confirmed abstinent. Participants responded to 87% of all prompted EMAs and received approximately 102 treatment messages over the 3-week EMA period. Most participants (83%, 49/59) used the on-demand app features. Individuals with greater nicotine dependence and minority race used the Quit Tips feature more than their counterparts. Greater use of the Quit Tips feature was linked to nonabstinence at the 2 (P=.02), 4 (P<.01), and 12 (P=.03) week follow-up visits. Most participants reported that they actually used or implemented the tailored app-generated messages and suggestions (83%, 49/59); the app-generated messages were helpful (97%, 57/59); they would like to use the app in the future if they were to lapse (97%, 57/59); and they would like to refer friends who smoke to use the Smart-T app (85%, 50/59). A minority of participants (15%, 9/59) reported that the number of daily assessments (ie, 5) was “too high.”ConclusionsThis novel just-in-time adaptive intervention delivered an intensive intervention (ie, 102 messages over a 3-week period), was well-liked, and was perceived as helpful and useful by socioeconomically disadvantaged adults who were seeking smoking cessation treatment. Smartphone apps may be used to increase treatment exposure and may ultimately reduce tobacco-related health disparities among socioeconomically disadvantaged adults.

Dispositional Mindfulness Predicts Enhanced Smoking Cessation and Smoking Lapse Recovery.

Although mindfulness has been hypothesized to promote health behaviors, no research has examined how dispositional mindfulness might influence the process of smoking cessation. The current study investigated dispositional mindfulness, smoking abstinence, and recovery from a lapse among African American smokers. Participants were 399 African Americans seeking smoking cessation treatment (treatments did not include any components related to mindfulness). Dispositional mindfulness and other psychosocial measures were obtained pre-quit; smoking abstinence was assessed 3, 31days, and 26weeks post-quit. Individuals higher in dispositional mindfulness were more likely to quit smoking both initially and over time. Moreover, among individuals who had lapsed at day 3, those higher in mindfulness were more likely to recover abstinence by the later time points. The mindfulness-early abstinence association was mediated by lower negative affect, lower expectancies to regulate affect via smoking, and higher perceived social support. Results suggest that mindfulness might enhance smoking cessation among African American smokers by operating on mechanisms posited by prominent models of addiction.

Positive Psychotherapy for Smoking Cessation: A Pilot Randomized Controlled Trial.

Greater depressive symptoms and low positive affect (PA) are associated with poor smoking cessation outcomes. Smoking cessation approaches that incorporate a focus on PA may benefit smokers trying to quit. The purpose of this study was to conduct a pilot randomized clinical trial to compare standard smoking cessation treatment (ST) with smoking cessation treatment that targets positive affect, termed positive psychotherapy for smoking cessation (PPT-S). Smokers who were seeking smoking cessation treatment were assigned by urn randomization to receive, along with 8 weeks of nicotine replacement therapy, either ST (n = 31) or PPT-S (n = 35). Seven-day point prevalence smoking abstinence was biochemically confirmed at 8, 16, and 26 weeks. Compared to ST, a greater percentage of participants in PPT-S were abstinent at 8 weeks, 16 weeks, and 26 weeks, but these differences were nonsignificant. In a more statistically powerful longitudinal model, participants in PPT-S had a significantly higher odds of abstinence (adjusted odds ratio [AOR] = 2.75; 95% CI = 1.02, 7.42; p = .046) across follow-ups compared to those in ST. The positive effect of PPT-S was stronger for those higher in PA (OR = 6.69, 95% CI = 1.16, 38.47, p = .03). Greater use of PPT-S strategies during the initial 8 weeks of quitting was associated with a less steep decline in smoking abstinence rates over time (OR = 2.64, 95% CI = 1.06, 6.56, p =.04). This trial suggests substantial promise for incorporating PPT into smoking cessation treatment.

Differential Efficacy of Nicotine Replacement Among Overweight and Obese Women Smokers.

Rates of obesity are higher among more dependent smokers and 37%-65% of smokers seeking cessation treatment are overweight or obese. Overweight or obese smokers may possess metabolic and neurobiological features that contribute to difficulty achieving cessation using front-line nicotine replacement products. Attention to factors that facilitate effective cessation treatment in this vulnerable population is needed to significantly reduce mortality risk among overweight and obese smokers. This secondary analysis of 2 large trials of transdermal nicotine replacement in general medical practices evaluated the hypothesis that higher body mass index (BMI) would moderate the efficacy of the nicotine patch. We examined the potential for gender to further moderate the relationship between BMI and treatment efficacy. In the placebo controlled trial (N = 1,621), 21-mg patch was no more effective than placebo for assisting biochemically verified point prevalence abstinence up to 1 year after quitting for women with higher BMI, but appeared to be effective for men at normal or high BMI (gender × BMI beta = -0.22, p = .004). We did not find differential long-term cessation outcomes among male or female smokers in the 15-mg patch trial (n = 705). However, we observed significantly higher rates of early lapse among women with higher BMI treated with nicotine patch across both trials. These results suggest that increased BMI may affect the efficacy of nicotine patch on reducing risk of early lapse in women. Additional research is needed to explore mechanisms of risk for decreased efficacy of this commonly used cessation aid.

Changes in the profiles of smokers seeking cessation treatment and in its effectiveness in Galicia (Spain) 2001-10.

BackgroundIn recent years, the prevalence of daily smokers has decreased in all developed countries due to a great variety of factors. Despite this decrease, the effectiveness of clinical treatments has decreased and several studies report a change in smokers’ characteristics. The purpose of the present study is to analyze the changes in the characteristics of Spanish smokers who seek smoking cessation treatment between 2001 and 2010 and the changes in the effectiveness of such treatment.MethodsThe sample was made up of 870 smokers who sought psychological treatment for giving up smoking at the Smoking Cessation Unit in the Faculty of Psychology of the University of Santiago de Compostela (Spain) during the period 2001 to 2010.ResultsSmokers in the 2006–2010 group, compared to those in the 2001–2005 group, were older, smoked fewer cigarettes per day and of a brand with fewer mg/nicotine, had been smoking longer, were less motivated to give up smoking, and had more antecedents of depression. Quit rates were validated by testing smokers' carbon monoxide (CO) levels.Percentages of abstinence were higher in the 2001–2005 group than in the 2006–2010 group (58.7% vs. 52.15 at the end of treatment, p = 0.05); 30.8% vs. 24.2% at 6 months follow-up, p = 0.031; 27.5% vs. 22% at 12 months follow-up, p = 0.059). Although abstinence decreased more than 5% in the 2006–2010 group there were no differences between the two groups in nicotine dependence. Those participants who did not assist to the follow-up were considered smokers at pretreatment level.ConclusionsIn Spain there has been a qualitative change in the profile of the smokers seeking smoking cessation treatment. Treatment effectiveness has decreased, and the variables predicting intervention outcome have changed.

Specific Associations between Anxiety Sensitivity Dimensions and Fear and Distress Dimensions of Emotional Distress Disorders.

Anxiety sensitivity (AS) comprises three lower-order dimensions, physical concerns, cognitive concerns, and social concerns, all of which are related to unipolar mood and anxiety disorders (emotional distress disorders). The pattern of these relations suggests that AS cognitive concerns might be best classified as associated with emotional distress disorders clustered together as distress disorders whereas AS physical concerns might be best classified as associated with emotional distress disorders clustered together as fear disorders. In contrast, AS social concerns appears to be generally associated with both fear and distress disorders. To test the specificity of lower-order AS dimensions, structural equation modeling was employed in a sample of 579 individuals (M age = 36.87 years, SD = 13.47; 51.6% male) constituting a sample at risk for psychopathology as these individuals were seeking smoking cessation treatment. AS physical concerns was associated with the fear disorders dimension, even when controlling for negative affect (NA). AS cognitive concerns was associated with the distress disorder dimension, only when the effects of NA were not included. Finally, AS social concerns demonstrated non-specific relations with both the distress and fear disorders dimensions. Given that measures of AS and psychopathology were collected concurrently, these findings cannot address the role of lower-order AS dimensions as risk factors for specific psychopathology clusters. These results provide further support for the hierarchical model of emotional distress disorders as well as implicate AS cognitive and physical concerns as important variables at the intermediate level of this model.

Predicting quit attempts among homeless smokers seeking cessation treatment: an ecological momentary assessment study.

Homeless adults are more likely to smoke tobacco and are less likely to successfully quit smoking than smokers in the general population, despite comparable numbers of cessation attempts and desire to quit. To date, studies that have examined smoking cessation in homeless samples have used traditional lab/clinic-based assessment methodologies. Real-time assessment of key variables may provide new insights into the process of quitting among homeless smokers. The purpose of the current study was to identify predictors of a quit attempt using real-time assessment methodology during the 6 days prior to a scheduled quit attempt among homeless adults seeking care at a shelter-based smoking cessation clinic. Parameters for multiple variables (i.e., motivation for quitting, smoking expectancies, quit self-efficacy, smoking urges, negative affect, positive affect, restlessness, hostility, and stress) were calculated and were used as predictors of biochemically verified quit date abstinence (i.e., ≥13hr abstinent) using logistic regression analyses. Participants (n = 57) were predominantly male (59.6%), non-White (68.4%), and smoked an average of 18 cigarettes per day. A total of 1,132 ecological momentary assessments (83% completion rate) were collected at random times (i.e., up to 4 assessments/day) during the 6 days prior to a scheduled quit attempt. Results indicated that declining (negative slope) negative affect, restlessness, and stress predicted quit date abstinence. Additionally, increasing positive coping expectancies across the prequit week predicted quit date abstinence. Study findings highlight multiple variables that may be targeted during the precessation period to increase smoking cessation attempts in this difficult to treat population of smokers.

Cannabis Use among Treatment‐Seeking Smokers: Motives and the Moderating Effects of Anxiety Sensitivity

Concurrent use of cannabis and tobacco is associated with poor tobacco cessation outcomes. As little research has examined why treatment-seeking tobacco users engage in cannabis use, the objective of this study was to discover if emotional vulnerability and cannabis use motives are associated with concurrent users' cannabis use. One hundred thirty-eight (n = 138) daily cigarette smokers seeking smoking cessation treatment completed measures of anxiety sensitivity, cannabis use motives, and cannabis use. Stronger coping, enhancement, social, and expansion motives were associated with using greater amounts of cannabis per use occasion. In a model accounting for all these motives, anxiety sensitivity moderated the relationship between enhancement motives and cannabis use. Clinical interventions for concurrent tobacco-cannabis users may be advanced by targeting low anxiety sensitive individuals' use of cannabis to increase excitement and fun. Such an approach may consist of having clients identify and engage in healthier pleasurable activities and by teaching clients to accept the trade-off between perceived less pleasurable, but healthier activities and cannabis use.
