Motives for smoking and their correlates in clients attending Stop Smoking treatment services

Does deterioration in mental health after smoking cessation predict relapse to smoking?

BACKGROUND

It is possible that some people who quit smoking experience improved mental health after cessation and therefore remain abstinent, whereas other people who quit may experience worse mental health after cessation and therefore be more likely to relapse to smoking. Thus, in this study we aimed to examine the association between an enduring change in mental health following the cessation period and future risk of relapse.

METHODS

A secondary analysis of prospective data pooled from five placebo-controlled randomised trials for smoking reduction conducted in Europe, USA and Australia. Change in mental health (SF-36, scored 0-100) was measured from baseline to four months for those who were biologically-validated as point-prevalence abstainers at four month follow-up. Thereafter we assessed whether relapse to smoking by 12 months was more likely in those whose mental health had worsened between baseline and four months compared with those who saw no change or an improvement.

RESULTS

After adjustment for baseline mental health and other major covariates, there was no greater tendency to relapse at 12 months for those whose mental health worsened after cessation compared with those who had no change or an improvement. The odds ratio and 95% confidence interval was 1.01 (0.97 to 1.05).

CONCLUSIONS

People whose mental health worsens after smoking cessation are at no greater risk of subsequent relapse to smoking than those whose mental health stays the same or improves.

Does smoking cessation result in improved mental health? A comparison of regression modelling and propensity score matching

OBJECTIVES

Smokers report that smoking is therapeutic; a recent meta-analysis suggests the contrary. However, the association in that review may be explained by group-membership bias and confounding. Propensity score matching (PSM) aims to produce causal estimates from observational data. We examined the association between cessation and change in mental health before and after PSM.

DESIGN

A secondary analysis of prospective data from 5 placebo-controlled randomised trials for smoking reduction.

PARTICIPANTS

All participants were adult smokers and had smoked for at least 3 years. Participants were excluded if they were pregnant, breast feeding, under psychiatric care, deemed to be unfit by a general practitioner or part of a cessation programme. In total, 937 participants provided smoking data at both 6-month and 12-month follow-ups. Of these, 68 were confirmed as abstinent at both 6 and 12 months and 589 as continuous smokers at both follow-ups.

PRIMARY OUTCOME

Change in mental health (36-item Short Form Survey (SF-36), scored 0-100) from baseline (while all participants were smokers) to 12-month follow-up (after cessation) was compared between quitters and continuing smokers with and without adjustment, and after PSM.

RESULTS

Before matching, quitters' mental health scores improved compared with continuing smokers', the mean difference and 95% CI was 5.5 (1.6 to 9.4). After adjustment, the difference was 4.5 (0.6 to 8.5), and after PSM, the difference was 3.4 (-2.2 to 8.9).

CONCLUSIONS

Improvements in mental health after smoking cessation may be partly but not completely explained by group membership bias and confounding.

Smoking and Smoking Increase in Caregivers of Alzheimer's Patients

PURPOSE OF THE STUDY

The relationship between stress and smoking has been established, but there is little research on the effects of stress and coping on smoking in caregivers of Alzheimer's disease patients. This study examines how caregiver stressors and coping resources explain smoking status and recent smoking increase.

DESIGN AND METHODS

Data were obtained from the Resources for Enhancing Alzheimer's Caregivers Health (REACH II) study. Analyses identified differences between caregiver smokers and nonsmokers and between caregiver smokers who reported a recent smoking increase and those who did not. Variables that were significantly different between the groups were examined in two logistic regression analyses to explain smoking status and smoking increase.

RESULTS

Of 642 caregivers, nearly 40% reported smoking and 25% of smokers reported recent increase in smoking. Younger caregivers were more likely to report smoking. Explanatory variables for smoking increase were being Caucasian or African-American, higher depression scores, and less caregiving skills.

IMPLICATIONS

This study demonstrates that smoking among caregivers is a valid public health concern. Further investigation of ways that explanatory variables affect smoking status and increase in caregivers, and incorporation of smoking cessation strategies that address depression and low caregiving skills, seem warranted in future caregiver interventions.

Gender and stimulus control of smoking behavior

INTRODUCTION

Gender differences in smoking behavior have been proposed to account for poorer outcomes among women attempting to quit. Specifically, it has been suggested that women's smoking behavior is less motivated by nicotine-seeking and more driven by environmental cues. To date, however, few real-world studies have examined the hypothesis that women's smoking is under greater stimulus control.

METHODS

One hundred and ninety four daily smokers (men = 107; women = 87) completed 3 weeks of ecological momentary assessment (EMA) monitoring that provided data on real-world smoking behavior by reporting on situational contexts shown by previous research to influence smoking behavior (including social setting, cigarette availability, alcohol consumption, and mood).

RESULTS

Analyses of particular cues found few gender differences; however, men's smoking increased to a greater extent compared with women's when they were with others who were smoking. Idiographic analyses that allow individual subjects to have different directions of linkage to situational cues also were conducted to assess how predictable subjects' smoking was from a range of contextual characteristics. Compared with women, men's smoking was significantly more closely tied to food/alcohol consumption and tended to be more closely tied to social context. No other gender differences were found.

CONCLUSIONS

EMA analyses suggest that men and women are similarly influenced by cues, including mood. Where there were gender differences, it was men rather than women whose smoking behavior was more influenced by cues. The data contradict the hypothesis that women's smoking is more influenced by cues.

Does smoking reduction worsen mental health? A comparison of two observational approaches

OBJECTIVES

The association between smoking reduction and mental health is of particular interest given that many smokers report that smoking offers mental health benefits. We aimed to assess the association between smoking reduction and change in mental health using two different analytical approaches to determine if there was any evidence of an association. There were no prior hypotheses.

DESIGN

A secondary analysis of prospective individual level patient data from 5 merged placebo-controlled randomised trials of nicotine replacement therapy for smoking reduction.

PARTICIPANTS

All participants were adult smokers, selected because they wanted to reduce but not stop smoking, and had smoked for at least 3 years. Participants were excluded if they were pregnant, breastfeeding, under psychiatric care, deemed to be unfit by a general practitioner, or part of a cessation programme. 2066 participants were enrolled in the trials, 177 participants were biologically validated as prolonged reducers, and 509 as continuing smokers at both 6-week and 18-week follow-ups.

PRIMARY OUTCOME

Change in mental health from baseline to an 18-week follow-up was measured using the emotional well-being subscale on the Short Form Health Survey-36.

RESULTS

After adjustment for confounding variables, the differences for reducers compared with continuing smokers were: regression modelling -0.6 (95% CI -4.4 to 3.2) and propensity score matching 1.1 (95% CI -2.0 to 4.1).

CONCLUSIONS

Smoking reduction, sustained for at least 12 weeks, was not associated with change in mental health, suggesting that reducing smoking was no better or worse for mental health than continuing smoking. Clinicians offering smoking reduction as a route to quit can be confident that, on average, smoking reduction is not associated with negative change in mental health.

Integrated psychological care in head and neck cancer: Views from health care providers, patients, and supports

OBJECTIVES/HYPOTHESIS

An evaluation by head-and-neck cancer (HNC) staff, patients, and patient support feedback regarding integrated psychological care and perceived benefit based on patient characteristics.

STUDY DESIGN

Cross-sectional survey of HNC staff, patients, and their primary supports; and retrospective chart review of psychiatric characteristics of HNC patients.

METHODS

HNC staff, patients (who were evaluated by the integrated psychologist), and their primary supports were given questionnaires on their perception of benefit of including a psychologist in the evaluation and treatment of HNC patients. Also, a retrospective chart review on patients who were psychiatrically evaluated by the psychologist on sociodemographics and psychiatric characteristics.

RESULTS

Overall, integration of a psychologist was well received by patients, supports, and staff. Younger patients reported greater satisfaction with the availability of the psychologist than older patients (P = .04), and patients with reported psychiatric histories (diagnoses in remission) indicated more satisfaction with the psychologist in relation to managing distress than patients who denied psychiatric histories (P = .03); however, patients who were currently smoking tended to report lower satisfaction with the psychologist helping with distress than those who were past/never smokers (P = .06).

CONCLUSIONS

Integrated psychological care has the potential to improve care provided for HNC patients.

Motivations toward smoking cessation, reasons for relapse, and modes of quitting: results from a qualitative study among former and current smokers

BACKGROUND

Smoking cessation plays a crucial role in reducing preventable morbidity and mortality and is a recognized public-health-policy issue in many countries. Two of the most important factors that affect the efficacy of quitting smoking are motivation and the ability to cope with situations causing relapse.

AIM

The objective of the study reported here was to investigate former and current smokers' motivations for smoking cessation, reasons for relapse, and modes of quitting.

METHODS

We arranged four focus groups with 24 participants (twelve current and twelve former smokers) and eleven semi-structured interviews (five current and six former smokers) with a view to understanding and categorizing their opinions on motivations and the course and process of smoking cessation. The data were next analyzed using descriptive qualitative methods.

RESULTS

THREE MAIN THEMES WERE IDENTIFIED: (1) motivations to quit smoking, (2) reasons why smokers sometimes relapse, and (3) modes of quitting smoking. Within the first theme, the following six subthemes surfaced: (1) a smoking ban at home and at work due to other people's wishes and rules, (2) the high cost of cigarettes, (3) the unpleasant smell, (4) health concern, (5) pregnancy and breastfeeding, and (6) a variety of other factors. The second theme encompassed the following subthemes: (1) stress and the need to lessen it by smoking a cigarette, (2) the need to experience the pleasure connected with smoking, and (3) the smoking environment both at home and at work. Participants presented different smoking-cessation modes, but mainly they were unplanned attempts.

CONCLUSION

Two very important motivations for smoking cessation were a smoking ban at home and at work due to other people's wishes and rules, and the high cost of cigarettes. The most common smoking-cessation mode was a spontaneous decision to quit, caused by a particular trigger factor. Relapse causes encompassed, most notably: stress, lack of the pleasure previously obtained from smoking, and the smoking environment.

Reasons for smoking among tri-ethnic daily and nondaily smokers

INTRODUCTION

Nondaily smokers experience adverse effects from tobacco use, yet they have been understudied compared to daily smokers. Understanding how reasons for smoking (RS) differ by smoking level, gender, and race/ethnicity could inform tailored interventions.

METHODS

A cross-sectional survey was administered through an online panel survey service to 2,376 current smokers who were at least 25 years of age. The sample was stratified to obtain equal numbers of 3 racial/ethnic groups (African American [AA], Latino, and White) across smoking level (native nondaily, converted nondaily, daily light, and daily moderate/heavy).

RESULTS

A 7-factor structure of a 20-item Modified Reasons for Smoking Scale (MRSS) was confirmed (each subscale alpha > 0.80). Each factor of the MRSS varied by smoking level, with nondaily smokers endorsing all RS less frequently than daily smokers (p < .0001). The 4 smoker subgroups incrementally differed from one another (p < .05) with several exceptions between converted nondaily and daily light smokers. Males reported stronger RS on 5 out of 7 reasons (p < .05). Females had higher scores on tension reduction/relaxation (p < .0001). Latinos reported stronger RS than Whites and AAs on all reasons (p < .05) except for tension reduction/relaxation (p > .05). AAs and Whites were comparable on all RS (p > .05).

CONCLUSIONS

The present study highlights considerable variability across smoking level, gender, and race/ethnicity in strength of RS. Addressing subgroup differences in RS may contribute to more sensitive and effective prevention and treatment efforts.

Change in mental health after smoking cessation: systematic review and meta-analysis

OBJECTIVE

To investigate change in mental health after smoking cessation compared with continuing to smoke.

DESIGN

Systematic review and meta-analysis of observational studies.

DATA SOURCES

Web of Science, Cochrane Central Register of Controlled Trials, Medline, Embase, and PsycINFO for relevant studies from inception to April 2012. Reference lists of included studies were hand searched, and authors were contacted when insufficient data were reported.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Longitudinal studies of adults that assessed mental health before smoking cessation and at least six weeks after cessation or baseline in healthy and clinical populations.

RESULTS

26 studies that assessed mental health with questionnaires designed to measure anxiety, depression, mixed anxiety and depression, psychological quality of life, positive affect, and stress were included. Follow-up mental health scores were measured between seven weeks and nine years after baseline. Anxiety, depression, mixed anxiety and depression, and stress significantly decreased between baseline and follow-up in quitters compared with continuing smokers: the standardised mean differences (95% confidence intervals) were anxiety -0.37 (95% confidence interval -0.70 to -0.03); depression -0.25 (-0.37 to -0.12); mixed anxiety and depression -0.31 (-0.47 to -0.14); stress -0.27 (-0.40 to -0.13). Both psychological quality of life and positive affect significantly increased between baseline and follow-up in quitters compared with continuing smokers 0.22 (0.09 to 0.36) and 0.40 (0.09 to 0.71), respectively). There was no evidence that the effect size differed between the general population and populations with physical or psychiatric disorders.

CONCLUSIONS

Smoking cessation is associated with reduced depression, anxiety, and stress and improved positive mood and quality of life compared with continuing to smoke. The effect size seems as large for those with psychiatric disorders as those without. The effect sizes are equal or larger than those of antidepressant treatment for mood and anxiety disorders.

Smokers who report smoking but do not consider themselves smokers: a phenomenon in need of further attention

BACKGROUND

Heightened stigma surrounding the action of smoking may decrease the likelihood that individuals who engage in smoking identify with the label 'smoker'. Non-identifying smokers (NIS) may undermine accurate smoking prevalence estimates and can be overlooked by tobacco control efforts.

OBJECTIVE

We sought to characterise NIS in a cross-sectional study using a sample representative of the population of adults (>18 years) in California who reported smoking at least 100 cigarettes in their lifetime, smoking at least some days and at least once in the last 30 days (n=1698). Individuals were considered NIS if they met the above criteria and answered 'no' when asked if they 'considered themselves a smoker'.

RESULTS

We estimate that 395 928 (SD=54 126) NIS were living in California in 2011 (a prevalence of 12.3% of all smokers in California). The odds of being NIS were higher among non-daily smokers who were previously daily smokers (adjusted OR (AOR)=7.63, 95% CI 2.67 to 21.8) or were never previously daily smokers (AOR=7.14, CI 2.78 to 18.3) compared with daily smokers. The odds of being an NIS were also higher among those who did not believe they were addicted to cigarettes (AOR=3.84, CI 1.68 to 9.22), were older than 65 years (vs less than 45 years) (AOR=3.35, CI 1.16 to 9.75) or were from ethnic minorities including Black and Asian (vs non-Hispanic white) (AOR=3.16, CI 1.19 to 8.49).

CONCLUSIONS

Smoking surveillance should restructure selection criteria to more accurately account for NIS in areas with high stigma toward smokers. Targeted interventions may be needed for NIS including educating healthcare providers to enquire more deeply into smoking habits.

The many faces of tobacco use among women

Smoking is still considered to be mainly a male problem. However, it is estimated that there are approximately 250 million women worldwide who smoke cigarettes and millions more women who use smokeless tobacco products. This article addresses the many facets of tobacco use among women. The aim of the paper is to increase recognition among clinicians and researchers of the specific characteristics of female tobacco use. Together with providing epidemiological data on the distribution of tobacco use among women and data from population-based analyses on sociocultural factors that influence it, the article presents tobacco use during pregnancy as a particularly important public health problem. Further, the article points out sex-related differences (ie, physiological, psychological, or behavioral) between male and female tobacco use. A special focus is on the important role of ovarian hormones. Adverse effects of tobacco use to women and their children as well as tobacco-related morbidities and comorbidities are presented, and women's greater susceptibility to tobacco constituents as compared to men is stressed. Awareness of these differences can contribute to improvement of the effectiveness of smoking cessation programs addressed both to the specific female population and to an individual smoking woman.

[What motivates smoking and alcohol drinking of young people? A behavioural epidemiologic study]

INTRODUCTION

Adolescence is a life period of trying harmful habits. It is helpful for prevention to map youth's motivations.

AIM

The main goal of the present study was to investigate high school students' motivations related to alcohol and cigarette use.

METHOD

A questionnaire survey was performed in Debrecen including students from four high schools (n = 501; age range, between 14 and 22 years; mean age, 16.4 years; 34% boys and 66% girls). Beyond descriptive statistics, logistic regression analysis was used to detect odds ratios explaining relationships between substance use and motivations.

RESULTS

Besides a slight difference in gender, there were significant differences by substance user status in the structure of motivations. In case of alcohol use, social motivation proved to be a predictor. In case of cigarette smoking, besides social motivation, boredom relief and affect regulation (coping) were also significant.

CONCLUSIONS

These data suggest that young people start to smoke cigarette and drink alcohol in social situations due to peer pressure. Therefore, prevention strategies should be built on social skills training.

Stress modulates illness-course of substance use disorders: a translational review

Childhood trauma and post-childhood chronic/repeated stress could increase the risk of a substance use disorder by affecting five stages of addiction illness-course: (a) initial experimentation with substances; (b) shifting from experimental to regular use; (c) escalation from regular use to abuse or dependence; (d) motivation to quit; and (e) risk of (re-)lapse. We reviewed the human literature on relationships between stress and addiction illness-course. We explored per illness-course stage: (i) whether childhood trauma and post-childhood chronic/repeated stress have comparable effects and (ii) whether effects cut across classes of substances of abuse. We further discuss potential underlying mechanisms by which stressors may affect illness-course stages for which we relied on evidence from studies in animals and humans. Stress and substances of abuse both activate stress and dopaminergic motivation systems, and childhood trauma and post-childhood stressful events are more chronic and occur more frequently in people who use substances. Stressors increase risk to initiate early use potentially by affecting trait-like factors of risk-taking, decision making, and behavioral control. Stressors also accelerate transition to regular use potentially due to prior effects of stress on sensitization of dopaminergic motivation systems, cross-sensitizing with substances of abuse, especially in people with high trait impulsivity who are more prone to sensitization. Finally, stressors increase risk for abuse and dependence, attenuate motivation to quit, and increase relapse risk potentially by intensified sensitization of motivational systems, by a shift from positive to negative reinforcement due to sensitization of the amygdala by corticotropin releasing factor, and by increased sensitization of noradrenergic systems. Stress generally affects addiction illness-course across stressor types and across classes of substances of abuse.

Positive smoker identity as a barrier to quitting smoking: findings from a national survey of smokers in England

BACKGROUND

It has been proposed that positive smoker identity may be an important factor undermining smoking cessation but very little research exists on this. This study tested the hypothesis that a simple measure of positive smoker identity would predict quit attempts over and above other known predictors in a population sample. More tentatively it explored whether this measure would also predict quit success.

METHODS

A representative sample of adult smokers in England (n=9456) was included at baseline and 2099 were followed-up at six months. Demographic and smoking characteristics, a single item measure of positive smoker identity (endorsing the statement: 'I like being a smoker'), measures of smoking-related attitudes, quit attempts and quit success were included.

RESULTS

A total of 18.3% (95% CI=17.5-19.2) of smokers reported a positive smoker identity. Adjusting for all other predictors, those with a positive smoker identity were more likely to be older (p<0.001), male (p=0.013), more nicotine dependent (p<0.001), have lower motivation to stop (p<0.001), have not made a quit attempt in the past year (p=0.025), enjoy smoking (p<0.001), and consider themselves to be addicted (p<0.001). Having a positive smoker identity independently predicted failure to make a quit attempt at six months (p=0.007). The independent association with quit success was similar in magnitude but did not reach statistical significance (p=0.053).

CONCLUSIONS

Only a minority of smokers in England have a positive smoker identity. However, where it is present it may be an important barrier to quitting smoking and merits further study.

MR and GR functional SNPs may modulate tobacco smoking susceptibility

A number of studies have demonstrated that stress is involved in all aspects of smoking behavior, including initiation, maintenance and relapse. The mineralocorticoid (MR) and glucocorticoid (GR) receptors are expressed in several brain areas and play a key role in negative feedback of the hypothalamic-pituitary-adrenal (HPA) axis. As nicotine increases the activation of the HPA axis, we wondered if functional SNPs (single nucleotide polymorphisms) in MR and GR coding genes (NR3C2 rs5522 and NR3C1 rs6198, respectively) may be involved in smoking susceptibility. The sample included 627 volunteers, of which 514 were never-smokers and 113 lifetime smokers. We report an interaction effect between rs5522 and rs6198 SNPs. The odds ratio (OR) for the presence of the NR3C2 rs5522 Val allele in NR3C1 rs6198 G carriers was 0.18 (P = 0.007), while in rs6198 G noncarriers the OR was 1.83 (P = 0.027). We also found main effects of the NR3C1 rs6198 G allele on number of cigarettes smoked per day (P = 0.027) and in total score of the Fagerström Test for Nicotine Dependence (P = 0.007). These findings are consistent with a possible link between NR3C2 and NR3C1 polymorphisms and smoking behavior and provide a first partial replication for a nominally significant GWAS finding between NR3C2 and tobacco smoking.

Negative mood effects on craving to smoke in women versus men

Negative mood situations increase craving to smoke, even in the absence of any tobacco deprivation (e.g. "stressors"). Individual differences in effects of negative mood situations on craving have received relatively little attention but may include variability between men and women. Across two separate within-subjects studies, we examined sex differences in craving (via the QSU-brief) as functions of brief smoking abstinence (versus satiation; Study 1) and acute induction of negative mood (versus neutral mood; Study 2). Subjective ratings of negative affect (via the Mood Form) were also assessed. In Study 1, we compared the effects of overnight (>12h) abstinence versus non-abstinence on craving and affect in adult male (n=63) and female (n=42) smokers. In Study 2, these responses to negative versus neutral mood induction (via pictorial slides and music) were examined in male (n=85) and female (n=78) satiated smokers. Results from each study were similar in showing that craving during the abstinence and negative mood induction conditions was greater in women than men, as hypothesized, although the sex difference in craving due to abstinence was only marginal after controlling for dependence. Craving was strongly associated with negative affect in both studies. These results suggest that very acute negative mood situations (e.g. just a few minutes in Study 2), and perhaps overnight abstinence, may increase craving to smoke to a greater extent in women relative to men.

Understanding treatment-seeking smokers' motivation to change: content analysis of the decisional balance worksheet

The Decisional Balance Worksheet (DBW), an open-ended measure of motivation to change, may be used to record the pros and cons of smoking versus abstinence among treatment-seeking smokers. Recent findings indicated that the open-ended DBW could be quantified to validly reflect people's level of motivation to stop smoking (Collins, Eck, Torchalla, Schröter, & Batra, 2010). The goal of the current study was to enhance our understanding of these participants' motivation to change by examining the qualitative content of their decisional balance. Participants were treatment-seeking smokers (N=268) who had participated in a larger randomized controlled trial of tailored smoking cessation interventions (Batra et al., 2010). Using the DBW, participants recorded their pros and cons of smoking versus abstinence, and content analysis methods were used to extract common themes. Findings indicated that the physical and psychological effects/functions of smoking and abstinence were most commonly mentioned as both pros and cons. Although the decisional balance categories were substantively similar over time, their relative frequency shifted from pre- to posttreatment. For the sample as a whole, the number of pros of smoking generally decreased, whereas the pros of abstinence increased from pre- to posttreatment. Findings suggest that clinicians can expect certain perceived pros and cons to characterize their clients' decision-making process about smoking and abstinence. At the same time, the use of the decisional balance allows for assessment of individuals' unique motivational set.

Smoking cessation and serious mental illness: a service evaluation of a drop-in stop smoking clinic on an acute in-patient unit

AIMS AND OBJECTIVES

To evaluate the effect of a stop smoking clinic on the quit rates of patients admitted to an acute in-patient unit.

BACKGROUND

The relationship between poor physical health and severe mental illness is well established. High rates of smoking appear to play an important causal role in the excess morbidity and mortality in this population. Stop smoking interventions for the general population are clinically effective and cost-effective. There is a small but promising evidence base for effective interventions to help people with a mental illness who wish to stop smoking but these have mostly been tested with community patients rather than acute in-patients.

METHODS

A service evaluation of a drop-in stop smoking clinic on an acute mental health in-patient unit was conducted. Patients' smoking status was measured at baseline and four weeks after their quit date using patient self-report and an expired breath carbon monoxide reading.

RESULTS

Over a six-month evaluation period, 46 patients set a quit date and 13 (28·3%) were abstinent at the four-week follow-up stage, verified by a carbon monoxide reading (χ(2) =33, df=1, sig p<0·0001).

CONCLUSIONS

This small-scale evaluation has shown a drop-in stop smoking intervention to be feasible, acceptable and associated with positive outcomes; further research with larger, more representative samples is required.

RELEVANCE TO CLINICAL PRACTICE

Enforcing smoke-free legislation is a contentious issue on mental health in-patient units, and there is a paucity of research to guide nursing practice in this area. An admission period in a smoke-free environment provides a crucial opportunity to offer smoking cessation treatment. With appropriate resources, expertise and support, it appears possible to apply smoking cessation interventions that are successful within the general population to mental health patients during an acute admission.

The electronic-cigarette: effects on desire to smoke, withdrawal symptoms and cognition

Electronic cigarettes (e-cigarettes) are battery operated devices that deliver nicotine via inhaled vapour. Few studies have evaluated acute effects on craving and mood, and none have explored effects on cognition. This study aimed to explore the effects of the White Super e-cigarette on desire to smoke, nicotine withdrawal symptoms, attention and working memory. Eighty-six smokers were randomly allocated to either: 18 mg nicotine e-cigarette (nicotine), 0mg e-cigarette (placebo), or just hold the e-cigarette (just hold) conditions. Participants rated their desire to smoke and withdrawal symptoms at baseline (T1), and five (T2) and twenty (T3) minutes after using the e-cigarette ad libitum for 5 min. A subset of participants completed the Letter Cancellation and Brown-Peterson Working Memory Tasks. After 20 min, compared with the just hold group, desire to smoke and some aspects of nicotine withdrawal were significantly reduced in the nicotine and placebo group; the nicotine e-cigarette was superior to placebo in males but not in females. The nicotine e-cigarette also improved working memory performance compared with placebo at the longer interference intervals. There was no effect of nicotine on Letter Cancellation performance. To conclude, the White Super e-cigarette alleviated desire to smoke and withdrawal symptoms 20 min after use although the nicotine content was more important for males. This study also demonstrated for the first time that the nicotine e-cigarette can enhance working memory performance. Further evaluation of the cognitive effects of the e-cigarette and its efficacy as a cessation tool is merited.

A Dutch version of the modified reasons for smoking scale: factorial structure, reliability and validity

AIMS

The Modified Reasons for Smoking Scale (MRSS) is a widely accepted scale that measures psychological functions of smoking. The scale has been translated in Dutch and has been validated, in order to be used in clinical smoking cessation practice in the Dutch-speaking part of Belgium. This study examined the factorial structure, reliability and validity of the scale in a sample of smokers, who are characterized by a high level of dependence and an explicit motivation to stop smoking.

METHOD

The participants were 383 smokers, who volunteered at the stop-smoking clinic of a Belgian university hospital, and completed the translated scale. They were administered the translated MRSS, the Fagerstrom Test for Nicotine Dependence (FTND). Through a clinical interview, smoking behaviour and smoking history was assessed (daily smoking consumption, years smoking, number of quit attempts, weeks stopped, alcohol and coffee consumption, CO level). Exploratory factor analysis was performed. Internal consistency was studied in order to examine the reliability. The concurrent validity was assessed by means of manova, anova and correlation analysis.

RESULTS

Factor analysis identified four factors, named stimulation, pleasure of smoking, social smoking and automatism of smoking. Cronbach's alpha ranged from 0.65 (automatism) to 0.72 (stimulation). manova indicated the influence of the variables age, sex, daily consumption and the FTND (the latter two variables showed a dose-dependent association with each subscale). Regression analysis revealed a relationship with dependence indicators, namely: the daily consumption, the number and duration of previous quit attempts, FTND, CO level and daily coffee intake.

CONCLUSIONS

The Dutch translation of the MRSS identified four factors and revealed acceptable validity and reliability. The adapted version of the translated scale as a component of the psychological assessment procedure in a smoking cessation treatment in Dutch-speaking areas should be implemented.

"I know it's bad for me and yet I do it": exploring the factors that perpetuate smoking in Aboriginal Health Workers--a qualitative study

Background

Aboriginal Health Workers (AHWs) have a mandate to deliver smoking cessation support to Aboriginal people. However, a high proportion of AHWs are smokers and this undermines their delivery of smoking cessation programs. Smoking tobacco is the leading contributor to the burden of disease in Aboriginal Australians and must be prevented. Little is known about how to enable AHWs to quit smoking. An understanding of the factors that perpetuate smoking in AHWs is needed to inform the development of culturally relevant programs that enable AHWs to quit smoking. A reduction of smoking in AHWs is important to promote their health and also optimise the delivery of smoking cessation support to Aboriginal clients.

Methods

We conducted a fundamental qualitative description study that was nested within a larger mixed method participatory research project. The individual and contextual factors that directly or indirectly promote (i.e. perpetuate) smoking behaviours in AHWs were explored in 34 interviews and 3 focus groups. AHWs, other health service staff and tobacco control personnel shared their perspectives. Data analysis was performed using a qualitative content analysis approach with collective member checking by AHW representatives.

Results

AHWs were highly stressed, burdened by their responsibilities, felt powerless and undervalued, and used smoking to cope with and support a sense of social connectedness in their lives. Factors directly and indirectly associated with smoking were reported at six levels of behavioural influence: personal factors (e.g. stress, nicotine addiction), family (e.g. breakdown of family dynamics, grief and loss), interpersonal processes (e.g. socialisation and connection, domestic disputes), the health service (e.g. job insecurity and financial insecurity, demanding work), the community (e.g. racism, social disadvantage) and policy (e.g. short term and insecure funding).

Conclusions

An extensive array of factors perpetuated smoking in AHWs. The multitude of personal, social and environmental stressors faced by AHWs and the accepted use of communal smoking to facilitate socialisation and connection were primary drivers of smoking in AHWs in addition to nicotine dependence. Culturally sensitive multidimensional smoking cessation programs that address these factors and can be tailored to local needs are indicated.

The endocrine effects of nicotine and cigarette smoke

With a current prevalence of approximately 20%, smoking continues to impact negatively upon health. Tobacco or nicotine use influences the endocrine system, with important clinical implications. In this review we critically evaluate the literature concerning the impact of nicotine as well as tobacco use on several parameters of the endocrine system and on glucose and lipid homeostasis. Emphasis is on the effect of smoking on diabetes mellitus and obesity and the consequences of smoking cessation on these disorders. Understanding the effects of nicotine and cigarettes on the endocrine system and how these changes contribute to the pathogenesis of various endocrine diseases will allow for targeted therapies and more effective approaches for smoking cessation.

Effectiveness of a Web-based multiple tailored smoking cessation program: a randomized controlled trial among Dutch adult smokers

Background

Distributing a multiple computer-tailored smoking cessation intervention through the Internet has several advantages for both provider and receiver. Most important, a large audience of smokers can be reached while a highly individualized and personal form of feedback can be maintained. However, such a smoking cessation program has yet to be developed and implemented in the Netherlands.

Objective

To investigate the effects of a Web-based multiple computer-tailored smoking cessation program on smoking cessation outcomes in a sample of Dutch adult smokers.

Methods

Smokers were recruited from December 2009 to June 2010 by advertising our study in the mass media and on the Internet. Those interested and motivated to quit smoking within 6 months (N = 1123) were randomly assigned to either the experimental (n = 552) or control group (n = 571). Respondents in the experimental group received the fully automated Web-based smoking cessation program, while respondents in the control group received no intervention. After 6 weeks and after 6 months, we assessed the effect of the intervention on self-reported 24-hour point prevalence abstinence, 7-day point prevalence abstinence, and prolonged abstinence using logistic regression analyses.

Results

Of the 1123 respondents, 449 (40.0%) completed the 6-week follow-up questionnaire and 291 (25.9%) completed the 6-month follow-up questionnaire. We used a negative scenario to replace missing values. That is, we considered respondents lost to follow-up to still be smoking. The computer-tailored program appeared to have significantly increased 24-hour point prevalence abstinence (odds ratio [OR] 1.85, 95% confidence interval [CI] 1.30–2.65), 7-day point prevalence abstinence (OR 2.17, 95% CI 1.44–3.27), and prolonged abstinence (OR 1.99, 95% CI 1.28–3.09) rates reported after 6 weeks. After 6 months, however, no intervention effects could be identified. Results from complete-case analyses were similar.

Conclusions

The results presented suggest that the Web-based computer-tailored smoking cessation program had a significant effect on abstinence reported after a 6-week period. At the 6-month follow-up, however, no intervention effects could be identified. This might be explained by the replacement of missing values on the primary outcome measures due to attrition using a negative scenario. While results were similar when using a less conservative scenario (ie, complete-case analyses), the results should still be interpreted with caution. Further research should aim at identifying strategies that will prevent high attrition in the first place and, subsequently, to identify the best strategies for dealing with missing data when studies have high attrition rates.

Mediation analysis of the association between use of NRT for smoking reduction and attempts to stop smoking

OBJECTIVES

Use of nicotine replacement therapy (NRT) for smoking reduction (SR) is linked to higher quit attempt rates than SR without NRT. This study aimed to assess the possible mediating roles of confidence in ability to quit, enjoyment of smoking and motivation to quit in this association.

DESIGN

Cross-sectional survey.

MAIN OUTCOME MEASURES

Smokers were asked if they were currently attempting SR, and if they were, whether they were using NRT. Motivation to stop, enjoyment of smoking, confidence in ability to stop, and previous quit attempts, were also assessed.

RESULTS

There was no evidence that confidence in ability to quit or enjoyment of smoking mediated the association between the use of NRT for SR and attempts to quit. Only motivation to stop partially mediated between the use of NRT for SR and attempts to stop (indirect effect: odds ratio 1.08, p < 0.001).

CONCLUSION

Although this study is limited by its cross-sectional design, the findings point towards the possibility that the use of NRT to aid SR may promote attempts to stop through increasing motivation to quit but not by increasing confidence or by reducing enjoyment of smoking. Longitudinal studies are required to draw firmer conclusions about the possible mediating effects of motivation to quit.

Tobacco addiction and the dysregulation of brain stress systems

Tobacco is a highly addictive drug and is one of the most widely abused drugs in the world. The first part of this review explores the role of stressors and stress-associated psychiatric disorders in the initiation of smoking, the maintenance of smoking, and relapse after a period of abstinence. The reviewed studies indicate that stressors facilitate the initiation of smoking, decrease the motivation to quit, and increase the risk for relapse. Furthermore, people with depression or an anxiety disorder are more likely to smoke than people without these disorders. The second part of this review describes animal studies that investigated the role of brain stress systems in nicotine addiction. These studies indicate that corticotropin-releasing factor, Neuropeptide Y, the hypocretins, and norepinephrine play a pivotal role in nicotine addiction. In conclusion, the reviewed studies indicate that smoking briefly decreases subjective stress levels but also leads to a further dysregulation of brain stress systems. Drugs that decrease the activity of brain stress systems may diminish nicotine withdrawal and improve smoking cessation rates.

Conflict About Quitting Predicts the Decision to Stop Smoking Gradually or Abruptly: Evidence From Stop Smoking Clinics in Malaysia

Background: Little is known about the extent to which smokers attending stop-smoking clinics experience conflicting motivations about their quit attempt, whether such conflict can be understood in terms of a single dimension and if this ‘conflict about quitting’ differs from motivation to stop smoking and is associated with a smoker's choice of method to stop smoking (stopping gradually or abruptly). Method: Sociodemographic, smoking and quit attempt characteristics as well as measures relating to conflict about stopping smoking were recorded in a cross-sectional survey of 198 smokers attending five quit smoking clinics in Malaysia. Results: Five measures (having seriously thought about quitting before, being happy about becoming a non-smoker, being strongly motivated to stop, intending to stop smoking completely and believing in stopping for good this time) were loaded onto a single factor that could be labelled ‘conflict about quitting’. The resultant scale had moderate internal reliability (Cronbach's α= .625). Most smokers exhibited conflicting motivations about stopping smoking, with over half (52.0%, 95% CI 45.1–59.1) scoring 2 or higher on the 5-point conflict scale. ‘Conflict about quitting’ was significantly associated with the decision to stop smoking gradually rather than abruptly controlling for other variables (OR 1.36, 95% CI 1.05–1.76) and was more strongly associated with the choice of smoking cessation method than motivation to stop smoking. Conclusions: ‘Conflict about quitting’ can be conceptualised as a single dimension and is prevalent among smokers voluntarily attending stop-smoking clinics. The finding that smokers who display greater conflict about quitting are more likely to choose gradual cessation may explain contradictory findings in the literature regarding the effectiveness of different methods of smoking cessation.

Point process analyses of variations in smoking rate by setting, mood, gender, and dependence

The immediate emotional and situational antecedents of ad-libitum smoking are still not well understood. We reanalyzed data from ecological momentary assessment using novel point process analyses to assess how craving, mood, and social setting influence smoking rate, as well as to assess the moderating effects of gender and nicotine dependence. Smokers (N = 304) recorded craving, mood, and social setting using electronic diaries when smoking and at random nonsmoking times over 16 days of smoking. Point process analysis, which makes use of the known random sampling scheme for momentary variables, examined main effects of setting and interactions with gender and dependence. Increased craving was associated with higher rates of smoking, particularly among women. Negative affect was not associated with smoking rate, even in interaction with arousal, but restlessness was associated with substantially higher smoking rates. Women's smoking tended to be less affected by negative affect. Nicotine dependence had little moderating effect on situational influences. Smoking rates were higher when smokers were alone or with others who were smoking, and smoking restrictions reduced smoking rates. However, the presence of others who are smoking undermined the effects of restrictions. The more sensitive point process analyses confirmed earlier findings, including the surprising conclusion that negative affect by itself was not related to smoking rates. Contrary to hypothesis, men's and not women's smoking was influenced by negative affect. Both smoking restrictions and the presence of others who are not smoking suppress smoking, but the presence of others who are not smoking undermines the effects of restrictions. Point process analyses of ecological momentary assessment data can bring out even small influences on smoking rate.

Biological mechanisms underlying the relationship between stress and smoking: state of the science and directions for future work

Theories of addiction implicate stress as a crucial mechanism underlying initiation, maintenance, and relapse to cigarette smoking. Examinations of the biological stress systems, including functioning of the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS), have provided additional insights into the relationship between stress and smoking. To date, convergent data suggests that chronic cigarette smoking is associated with alterations in HPA and ANS functioning; however, less is known about the role of HPA and ANS functioning in smoking initiation and relapse following cessation. In order to organize existing findings and stimulate future research, the current paper summarizes the available literature on the roles of HPA axis and ANS functioning in the relationship between stress and cigarette smoking, highlights limitations within the existing literature, and suggests directions for future research to address unanswered questions in the extant literature on the biological mechanisms underlying the relationship between stress and smoking.

Effects of nicotine on attention and inhibitory control in healthy nonsmokers

Nicotine improves cognitive functioning in smokers and psychiatric populations, but its cognitive-enhancing effects in healthy nonsmokers are less well understood. Nicotine appears to enhance certain forms of cognition in nonsmokers, but its specificity to subtypes of cognition is not known. This study sought to replicate and extend previous findings on the effects of nicotine on cognitive performance in healthy nonsmokers. Healthy young adults (N = 40, 50% women) participated in a placebo-controlled, double-blind, repeated measures experiment examining the effects of 7 mg transdermal nicotine or placebo. Participants completed tests of attention (Attention Network Test), behavioral inhibition (stop signal task, Stroop test), reward responsiveness (signal detection task), and risk-taking behavior (Balloon Analogue Risk Task). Physiological (heart rate, blood pressure) and subjective (Profile of Mood States, Drug Effects Questionnaire) measures were also obtained. Nicotine significantly improved performance only on the Stroop test, but it impaired performance on one aspect of the Attention Network Test, the orienting effect. Nicotine produced its expected effects on physiologic and subjective measures within the intended time course. The findings of this study contribute to a growing literature indicating that nicotine differentially affects specific subtypes of cognitive performance in healthy nonsmokers.

The role of desire, duty and intention in predicting attempts to quit smoking

AIMS

Motivation to quit smoking predicts quit attempts, although little is known about the role played by its different aspects. This study assessed the predictive value of desire, duty and intention to quit, three different aspects of motivation.

DESIGN

A longitudinal study was conducted involving a nationally representative sample of smokers assessed at baseline and 3 and 6 months later. Baseline assessment took place by face-to-face computer-assisted interviews; follow-up assessments by postal questionnaires.

SETTING

England.

PARTICIPANTS

From April 2008 to June 2009, a total of 5593 adult smokers were recruited; 1263 were followed-up at 3 months and 1096 at 6 months.

MEASUREMENTS

Three dichotomous measures of motivation to quit (wanting to quit, believing one ought to quit, intention to quit soon) were taken at baseline. Whether a subsequent quit attempt was made was recorded at 3- and 6-month follow-up.

FINDINGS

More smokers believed they ought to quit smoking than wanted to or intended to soon (39.0, 29.3 and 23.5%, respectively). Desire and intention were independent predictors of quit attempts at both follow-ups, whereas combining them did not add predictive value and duty was not a predictor. While the predictive value of desire or intention alone disappeared when accompanied by duty, their combination was robust against its negative effect.

CONCLUSIONS

Desire and intention independently positively predict quit attempts, while duty appears to mitigate their effect. It would be worth monitoring all three aspects of motivation when evaluating the impact of smoking cessation interventions on motivation to quit.

Predictors of 3-month abstinence in smokers attending stop-smoking clinics in Malaysia

INTRODUCTION

Much is known about the predictors of success in quitting smoking. In particular, nicotine dependence, but not strength of motivation to stop, appears to predict abstinence. However, to date, studies have come almost exclusively from Western countries. More data are needed on the cross-cultural generalizability of these findings.

METHODS

One hundred and ninety-eight smokers attending 5 stop-smoking clinics in Malaysia completed a questionnaire prior to their target quit date and were followed up 3 months after this date. Predictors included sociodemographic variables, smoking patterns, past history of quitting, characteristics of current quit attempt, and smoking motives as well as nicotine dependence (Fagerström Test for Nicotine Dependence [FTND]) and self-rated strength of motivation of stop.

RESULTS

At 3-month follow-up, 35.4% (95% CI: 28.7-42.0) of participants reported being abstinent. A backward elimination multiple logistic regression identified a number of significant predictors of success, including strength of motivation to stop (adjusted odds ratio [OR]: 3.05, 95% CI: 1.28-7.25). FTND did not predict success.

CONCLUSIONS

Motivation and nicotine dependence may play different roles in explaining variation in ability to stop smoking in different cultures.

The effect of stopping smoking on perceived stress levels

AIMS

Many smokers believe that smoking helps them to cope with stress, and that stopping smoking would deprive them of an effective stress management tool. Changes in stress levels following long-term smoking cessation are not well mapped. This longitudinal project was designed to provide more robust data on post-cessation changes in perceived stress levels by following a cohort of smokers admitted to hospital after myocardial infarction (MI) or for coronary artery bypass (CAB) surgery, as such patients typically achieve higher continuous abstinence rates than other comparable samples.

DESIGN

A total of 469 smokers hospitalized after MI or CAB surgery and wanting to stop smoking were seen in the hospital and completed 1-year follow-ups. Ratings of helpfulness of smoking in managing stress at baseline, smoking status (validated by salivary cotinine concentration) and ratings of perceived stress at baseline and at 1-year follow-up were collected.

FINDINGS

Of the patients, 41% (n = 194) maintained abstinence for 1 year. Future abstainers and future smokers did not differ in baseline stress levels or in their perception of coping properties of smoking. However, abstainers recorded a significantly larger decrease in perceived stress than continuing smokers, and the result held when possible confounding factors were controlled for (P < 0.001).

CONCLUSIONS

In highly dependent smokers who report that smoking helps them cope with stress, smoking cessation is associated with lowering of stress. Whatever immediate effects smoking may have on perceived stress, overall it may generate or aggravate negative emotional states. The results provide reassurance to smokers worried that stopping smoking may deprive them of a valuable coping resource.

Outcome expectations and use of smokeless tobacco (snus): a cross-sectional study among young Norwegian snus users

In this study, measures of outcome expectancies related to use of snus (wet snuff) were used to predict reported frequency of snus use. Data stem from a nation-wide survey in Norway among 16- to 20-year-olds. Only users of snus were included in the statistical analyses (n = 589). The main outcome measure, frequency of snus use, was measured as a categorical variable - occasional, weekly and daily use. Four dimensions of outcome expectancies (mood regulation, smoking control, weight control and negative health outcomes) were measured and confirmed in a confirmatory factor analysis. Informants tended to believe that snus use is harmful to health, but still they supported the idea of snus as a way to control own cigarette smoking. In a SEM model, two of the four dimensions of outcome expectancies turned out to be particularly significant predictors of frequency of snus use - mood regulation and smoking control. No significant interactions with gender were found. Males scored higher than females on "mood regulation", and "smoking control", while females scored higher than males on "negative health outcomes". If more smokers were convinced that snus use is a less harmful alternative, more of them might start using snus, not only because there is some association between health outcome expectancies and snus use, but also because snus use by many is perceived as a remedy to stop smoking and as a way to gain some of the mood regulation benefits which are usually associated with smoking.

Differences between intermittent and light daily smokers in a population of U.S. military recruits

INTRODUCTION

Few studies have assessed differences between intermittent and light smokers, particularly among young adults. Exploring these differences promotes a systematic approach to research and treatment in low-level smokers. This study explored demographic, tobacco-related, and psychosocial predictors of intermittent nondaily smoking relative to light smoking among basic military training (BMT) recruits. The impact of smoking status on abstinence rates at follow-up was also assessed.

METHODS

Participants were 5,603 U.S. Air Force BMT intermittent nondaily (n = 3,134) or light daily (n = 2,469) smoking recruits participating in a population-based group randomized trial targeting tobacco use prevention and cessation (Klesges et al., 2006, Efficacy of a tailored tobacco control program on long-term use in a population of U.S. military troops. Journal of Consulting and Clinical Psychology, 74, 295-306.). Participants completed baseline measures assessing demographics; tobacco use and history; and common social, attitudinal, and behavioral risk factors for tobacco use. Flights of recruits were randomly assigned to a tobacco use intervention or health education control intervention. At the 1-year follow-up, participants reported 7-day point prevalence and continuous abstinence.

RESULTS

Intermittent nondaily smoking relative to light daily smoking was associated with lesser perceived addiction, intermittent and daily use of smokeless tobacco, nonsmoking male and female heads of household, lesser likelihood of smoking while stressed or while bored, and higher likelihood of intentions to quit smoking. Intermittent smokers were significantly more likely than light daily smokers to report abstinence at follow-up.

DISCUSSION

Intermittent and daily light smokers differ on several tobacco-related and psychosocial variables. Attending to these factors in prevention and cessation programs may enhance abstinence in both groups.

The multiple facets of cigarette addiction and what they mean for encouraging and helping smokers to stop

Addiction involves powerful motivation to engage in an activity repeatedly to an extent that is harmful often accompanied by impaired capacity for self-control. To effectively combat addiction to cigarettes requires an understanding that there are several mechanisms underlying it. The PRIME Theory of motivation aims to provide a model that can encapsulate these mechanisms. It recognises that evolution has led to multiple levels of motivation from basic impulses and inhibitions, through 'motives' (feelings of want and need), to 'evaluations' (beliefs about what is good or bad), and plans (intentions regarding future actions). Self-control involves self-consciously generating motives from evaluations or plans; it requires and depletes mental energy. Nicotine from cigarettes generates the motivation to smoke and undermines self-control by interacting with all of the level of motivation. It: creates stimulus-impulse associations resulting in cue-driven urges; impairs inhibitory control; gives enjoyment resulting in 'wanting' to smoke; it leads to 'nicotine hunger', withdrawal symptoms and beliefs about benefits of smoking (e.g. stress relief) all of which can result in a 'need' to smoke. Evidence is emerging that wanting to smoke (because of enjoyment) is a major deterrent to making quit attempts but does not influence success, while cue-driven impulses to smoke, nicotine hunger and adverse mood and beliefs about the benefits of smoking are important in relapse. Combating cigarette addiction requires attention to all of these factors.

Best practices for smoking cessation: implications for employer-based programs

Tobacco use and smoking continue to be one of the most important potentially preventable health problems of the 21st century. A large number of studies published in the peer-reviewed literature now inform much of our employer-based programming efforts. Worksite settings and health plan member populations are served primarily through worksite-based interventions, which are examined in this literature review. As a consequence, a number of important resulting "best practices" for smoking cessation efforts with employed populations are presented for consideration in this edition of The Art of Health Promotion.

Self-perceived smoking motives and their correlates in a general population sample

INTRODUCTION

Understanding motivation to continue smoking may help the development of smoking cessation interventions. However, little information exists on the prevalence of specific motives for smoking in representative samples of smokers. This study examined smokers' reports of their motives for continued smoking in an English general population sample.

METHODS

A total of 2,133 smokers participating in monthly cross-sectional surveys (the Smoking Toolkit Study) identified which, if any, of the following motives they believed were important in keeping them smoking: enjoyment, stress relief, weight control, boredom relief, aid to concentration, aid to socializing, pain relief, liking being a smoker, and feeling bad when not smoking. Associations between these motives and gender, age, social grade, Fagerström Test for Nicotine Dependence, and quit attempts in the last year were examined using logistic regression.

RESULTS

Enjoyment and stress relief were the most commonly reported motives (51% and 47%, respectively). Women reported stress relief and weight control more often than men, whereas men were more likely to report enjoyment and liking being a smoker. Older smokers reported enjoying smoking and liking being a smoker more than younger smokers but were less likely to report socializing and stress relief as important motives. Not having made a quit attempt in the last year was associated with enjoying smoking and liking being a smoker. Higher dependence was associated with a greater number of reported motives.

DISCUSSION

While smoking for stress relief is common, perceptions of enjoyment of smoking and positive smoker identity may be the key motives that inhibit attempts at cessation.
