Smoking in movies, implicit associations of smoking with the self, and intentions to smoke

We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior.     

Implicit associations between smoking and social consequences among smokers in cessation treatment

Explicit expectations of the negative and positive social consequences of smoking are likely to have substantial influence on decisions regarding smoking. However, among smokers trying to quit, success in smoking cessation may be related not only to the content of expectancies about smoking's social effects but also to the ease with which these cognitive contents come to mind when confronted with smoking stimuli. To examine this possibility, we used the implicit association test (IAT) [Greenwald, A. G., McGhee, D. E., & Schwartz, J. L. K. (1998). Measuring individual differences in implicit cognition: The implicit association test. Journal of Personality and Social Psychology, 74, 1464-1480] to assess implicit cognitive associations between smoking and negative vs. positive social consequences among 67 heavy social drinkers seeking smoking cessation treatment in a randomized clinical trial. Results showed that the relative strength of implicit, negative, social associations with smoking at baseline predicted higher odds of smoking abstinence during treatment over and above the effects of relevant explicit measures. The only variable that significantly correlated with IAT scores was the density of smokers in participants' social environment; those with more smoking in their social environment showed weaker negative social associations with smoking. Results suggest implicit cognition regarding the social consequences of smoking may be a relevant predictor of smoking cessation outcome.     

Adolescent personality antecedents of adult cigarette smoking: a longitudinal study

Comprehensive personality assessments, made independently for early and late adolescence, were employed to predict smoking onset and maximum number of cigarettes smoked per day as reported by adult smokers. Also, comparisons were made between adult smokers and nonsmokers. The results indicate that men who had been more sexually active as adolescents smoked more but that women who had been more emotionally constricted and under more conflict as adolescents were heavier smokers. Smoking started earlier for men who had showed little self-awareness and a rather macho orientation during their adolescence; early-smoking women tended to have been conventionally feminine. Personality differences between future smokers and nonsmokers were few but showed similar sex differences. The results suggest that manifesting once traditional sex-role characteristics for both adolescent boys and girls presages early onset and heavier adult cigarette smoking. Preventive antismoking educational campaigns aimed at youth might be guided by these findings because they suggest some motivational bases that may find later expression in smoking practices.     

Prevalence of cigarette smoking in Iran.

The current research assessed the prevalence of cigarette smoking in Shiraz, Iran by randomly selecting 1,335 subjects (782 men and 553 women) from the city for a face-to-face interview and completion of a questionnaire. Of the participants, 205 (26%) of the men and 20 (3.6%) of the women reported being current smokers. The mean ages of smokers and nonsmokers were 41.8 and 37.0 yr., respectively (range between 16 and 90 years for smokers and nonsmokers). The mean age of starting to smoke cigarettes was 21.3 yr. (range of 10 to 60). The most common reasons for current cigarette smoking were Need to avoid withdrawal symptoms, Release of tension, and Pleasurable purposes. Foreign filter-tipped cigarettes were the most common type consumed. The mean number of cigarettes per day was 13.4 (SD = 10.3). Reports for onset of cigarette smoking included Modeling, Release of tension, and Pleasurable purposes. Cigarette smoking was reported by more males than females. The most common reason for onset of cigarette smoking was different from that for current smoking. Frequencies of smokers within age groups were varied.     

Does cigarette smoking cause stress?

Smokers often report that cigarettes help relieve feelings of stress. However, the stress levels of adult smokers are slightly higher than those of nonsmokers, adolescent smokers report increasing levels of stress as they develop regular patterns of smoking, and smoking cessation leads to reduced stress. Far from acting as an aid for mood control, nicotine dependency seems to exacerbate stress. This is confirmed in the daily mood patterns described by smokers, with normal moods during smoking and worsening moods between cigarettes. Thus, the apparent relaxant effect of smoking only reflects the reversal of the tension and irritability that develop during nicotine depletion. Dependent smokers need nicotine to remain feeling normal. The message that tobacco use does not alleviate stress but actually increases it needs to be far more widely known. It could help those adult smokers who wish to quit and might prevent some schoolchildren from starting.     

Prevalence and predictors of transitions in smoking behavior among college students.

The prevalence of smoking among college students is surprisingly high and represents a significant public health issue. However, there are few longitudinal studies of smoking in this population. This study examined the prevalence and predictors of transitions in smoking behavior among a cohort of 548 college students. Over the course of 4 years, 87% of daily smokers and almost 50% of occasional smokers continued to smoke. Among nonsmokers, 11.5% began smoking occasionally and none became daily smokers. In general, predictors of smoking behavior change were significant only among baseline occasional smokers and included gender, smoking outcome expectancies, and affect regulation expectations. Peer and parental smoking, demographics, affect, stress, and alcohol use were generally not predictive of change. Tobacco control interventions targeted at college students are clearly warranted.     

Smoking related to anxiety and depression in Greek medical staff

We assessed the relation of anxiety and depression to smoking behavior in a sample of 80 physicians and surgeons, using the Spielberger State-Trait Anxiety Scale and the Beck Depression Inventory. 27 doctors were nonsmokers, 14 were former smokers, and 39 were current smokers. Current smokers showed significantly higher Anxiety and Depression scores compared to nonsmokers and former smokers, while the latter presented significantly lower Anxiety scores than nonsmokers. In current smokers, the daily quota of cigarettes was not correlated with Anxiety or Depression scores. From our results we can hypothesize that, among medical staff, smoking behavior is more anxiety-related than depression-related. In conclusion, we believe that interventions such as stress management techniques could be effective in lessening Anxiety and diminishing the need for relief searched for in smoking.     

Marijuana Use Among Daily Tobacco Smokers: Relationship to Anxiety-Related Factors

The present investigation evaluated the incremental validity of regular marijuana use and frequency of such use in relation to anxiety and depressive symptoms and perceived health among young adult tobacco smokers (n = 202). Approximately 72% of the sample were current marijuana smokers, using this drug on an average of 7.6 (SD = 9.2) times per week. As expected, after controlling for theoretically-relevant smoking (cigarettes per day), alcohol use, and affect factors (i.e., negative affectivity and anxiety sensitivity), marijuana use predicted anxiety symptoms and perceived general health, whereas frequency of marijuana use predicted only anxiety symptoms. These results are discussed in relation to better understanding the role of regular marijuana use in terms of anxiety-relevant emotional vulnerability and beliefs about physical health among regular smokers.     

Anxiety sensitivity: association with intensity of retrospectively-rated smoking-related withdrawal symptoms and motivation to quit

The present cross-sectional study evaluated the associations between anxiety sensitivity, intensity of retrospectively-rated nicotine withdrawal symptoms, and motivation to quit smoking. Participants were 127 young adult (mean age 20.4 years (SD 4.6)) regular smokers (mean cigarettes per day 10.2 (SD 5.1)). Anxiety sensitivity predicted intensity of retrospectively rated withdrawal symptoms during the first week of the most recent quit attempt as well as concurrent and lifetime indices of motivation to quit smoking even after controlling for theoretically-relevant smoking (e.g. nicotine dependence) and affect (e.g. panic attack history) factors. These results are discussed in relation to better understanding panic-related vulnerability factors in smoking cessation.     

Gustatory responses during periods of controlled and ad lib cigarette smoking

Three psychophysical methods, differential sensitivity, perceived intensity, and degree of liking, were used to measure gustatory responses among nonsmokers and among smokers who were placed on 2-week schedules of increased and decreased cigarette consumption. Varying the smoking levels had little influence on the smokers’ sensitivity to the tastes of sucrose and sodium chloride. Throughout the experiments, nonsmokers were slightly more sensitive than smokers. Lower intensity ratings were ascribed to both compounds by smokers than by nonsmokers. Degree of liking of the test solutions was unrelated to smoking. A subsequent experiment showed that 45 nonsmokers were slightly, but not significantly, more sensitive than were 45 smokers to the tastes of sucrose, sodium chloride, citric acid, and quinine hydrochloride, with no differences in their sensitivity to the odor of 2-butanone and to the viscosity imparted by carrageenan gum. There was a slight inverse relationship between sensitivity and the number of cigarettes smoked per day. Smokers liked coffee significantly better and drank more cups per day than did nonsmokers. Few changes in body weight were observed, despite the smokers’ subjective assessment that their appetites and food intake were inversely related to the number of cigarettes smoked.     

Perceived health: a test of incremental validity in relation to smoking outcome expectancies, motivation to smoke and desire to quit smoking

This study examined the role of perceived health in predicting theoretically-relevant aspects of smoking behavior among 161 young adult regular smokers (67 females; mean age = 21.9 years (SD = 7.2), cigarettes per day (M) = 12.2 (SD = 5.7)) recruited from the general community. Consistent with prediction, results indicated that relative to anxiety sensitivity, gender, number of cigarettes smoked per day and nicotine dependence, perceived physical health uniquely and significantly predicted expectancies for negative affect reduction and expectancies that smoking would lead to negative personal consequences. Additionally, perceived health incrementally predicted motivation to smoke to reduce negative affect. In contrast to expectation, perceived health was unrelated to motivation to quit smoking. Results are discussed in relation to the role of perceived health as a cognitive vulnerability factor for specific types of smoking patterns.     

Concurrent associations between anxiety sensitivity and perceived health and health disability among young adult daily smokers

The aim of this investigation was to evaluate the incremental validity of anxiety sensitivity (fear of arousal-related physical and psychological sensations) relative to health factors (smoking variables, alcohol use and exercise level), in predicting perceived health and disability among a sample of 225 young adult daily smokers (102 females; M(age) = 23.9 years, SD = 8.8). Consistent with prediction, anxiety sensitivity, relative to smoking-relevant variables, alcohol consumption (a single frequency by quantity composite) and exercise activity, predicted lower perceived general health and impairments in mental health and social functioning; no incremental effects were evident for anxiety sensitivity for predicting impairments in physical functioning, role functioning, or increased healthcare usage. These findings are discussed with respect to better understanding cognitive factors that affect perceptions of health status and functioning among daily smokers.     

Effects of tobacco smoking on electroencephalographic, auditory evoked and event related potentials

After overnight abstinence, tobacco smokers smoked an average nicotine yield cigarette and nonsmokers sham smoked an unlit placebo cigarette. EEG alpha(1), delta, and theta frequency amplitudes decreased, whereas alpha(2) and beta frequency amplitude increased. Short, middle (EP) and long latency ERP were also studied in nonsmokers and smokers just after smoking, and after overnight abstinence from tobacco. Short latency potentials were unaffected by tobacco smoking or abstinence. Middle and long-latency potentials were reduced during abstinence and enhanced immediately after tobacco smoking. These findings indicate that compared to nonsmokers smokers have a higher arousal level after smoking than when partially abstinent. Evidence for both normalization from tobacco abstinence as well as stimulation was obtained.     

Learned resourcefulness, drinking, and smoking in young adults

The purpose of this study was to examine the relationship between learned resourcefulness and two common addictive behaviors, namely, drinking and smoking. Male and female college students (N = 175) completed the Self-Control Schedule (SCS), the Quantity-Frequency-Variability questionnaire, and a smoking history form. Learned resourcefulness was related to self-reported patterns of alcohol consumption; specifically, heavy drinking subjects were lower in learned resourcefulness than were light and moderate drinkers who, in turn, were lower in learned resourcefulness than were infrequent drinkers and abstainers. Learned resourcefulness was only modestly related to smoking, with students who had never smoked evidencing somewhat higher learned resourcefulness than ex-smokers and current smokers. Overall, these data provide correlational support for the notion that learned resourcefulness may protect young adults against substance abuse.     

Co-occurrent use of cigarettes, alcohol, and coffee in healthy, community-living men and women

Previous studies have examined intra-individual aggregation in the use of cigarettes, alcohol, and coffee by examining the co-occurrent use of any pair of these three substances. A recent literature review failed to find a single investigation that studied use of all three in the same sample. In the present study, co-occurrent use of all three of these substances was examined in crossvalidated subsamples of 226 male and 245 female healthy, community-living, middle-class Americans. A log-linear analysis was used to compare the proportion of smokers, ex-smokers, and nonsmokers categorized as users of more or less amounts of coffee and alcohol. Although most of the intercorrelations were not strong, the results indicate that for both sexes, smokers and ex-smokers were more likely than nonsmokers to drink greater amounts of alcohol and coffee. Furthermore, for smokers, ex-smokers, and nonsmokers, a majority of individuals who reported drinking more alcohol also reported drinking more coffee. Interestingly, the coffee and alcohol consumption levels of ex-smokers resembled those of smokers more than those of nonsmokers. Also, ex-smokers reported drinking more wine and decaffeinated coffee than either smokers or nonsmokers. Finally, the number of cigarettes smoked per day (daily quantity) was positively related to total alcohol and coffee consumption in men, but not in women. Further studies are recommended to examine the role of individual differences in the development, maintenance, and modification of these three appetitive habits and their co-occurrence.     

The effects of smoking on the speaking fundamental frequency of adult women

The present study sought to investigate the effects of smoking on the speaking fundamental frequency of adult women. The results indicated that, in the reading condition, fundamental frequency for the smokers was significantly lower than fundamental frequency for the nonsmokers. Eighty-seven percent of the smokers examined by an otolaryngologist exhibited some abnormality in appearance of the vocal folds. The results also suggest that menopause may contribute to a lowering of the speaking fundamental frequency of adult women.     

Five‐Year Prospective Study of Risk Factors for Daily Smoking in Adolescence Among Early Nonsmokers and Experimenters1

Grade 7 nonsmokers and experimenters (N= 4,165) were compared on a wide range of risk factors for future smoking derived from four prominent theories and whether these factors predicted daily smoking at Grade 12. Early experimenters scored consistently higher than did early nonsmokers on risk factors for future smoking. Common predictors of Grade 12 daily smoking for both groups included early exposure to an important adult who smokes, being young for one's cohort, and weak academic bonds. For Grade 7 non‐smokers, unique predictors of daily smoking included exposure to pro‐smoking social influences (cigarette offers, sibling who smokes), early binge drinking, and being female. Unique predictors for early experimenters were less sharply delineated, although certain family factors appeared to be more important for this group. African Americans and His‐panics were also less likely to progress from experimental to daily smoking. Results point to the importance of adapting prevention efforts to the special needs of early nonsmokers and experimenters.

The results suggest that manifesting once traditional sex-role characteristics for both adolescent boys and girls presages early onset and heavier adult cigarette smoking. Preventive antismoking educational campaigns aimed at youth might be guided by these findings because they suggest some motivational bases that may find later expression in smoking practices.     

The subjective effects of alcohol-tobacco co-use: an ecological momentary assessment investigation

Alcohol and tobacco use covary at multiple levels of analysis, and co-use of the 2 substances may have profound health consequences. To characterize the motivationally relevant processes contributing to co-use, the current study used ecological momentary assessment (EMA) to examine the subjective consequences of naturally occurring simultaneous use of alcohol and tobacco. Current smokers who reported frequently drinking alcohol (N=259) used electronic diaries to monitor their daily experiences for 21 days. Participants responded to prompted assessments and also initiated recordings when they smoked a cigarette or completed the first drink in a drinking episode. Momentary reports of smoking and alcohol consumption were associated with one another, and these effects remained after adjustment for occasion- and person-level covariates. When participants consumed alcohol, they reported increased pleasure and decreased punishment from the last cigarette. Smoking was associated with small increases in pleasure from the last drink. Ratings of buzzed and dizzy were synergistically affected by co-use of alcohol and tobacco. Co-use was also followed by higher levels of craving for both alcohol and tobacco. Results point to the importance of reward and incentive processes in ongoing drug use and suggest that alcohol intensifies real-time reports of the motivational consequences of smoking more strongly than smoking affects corresponding appraisals of alcohol effects.     

Long-term psychological sequelae of smoking cessation and relapse.

The authors examined whether smoking cessation and relapse were associated with changes in stress, negative affect, and smoking-related beliefs. Quitters showed decreasing stress, increasing negative health beliefs about smoking, and decreasing beliefs in smoking's psychological benefits. Quitters became indistinguishable from stable nonsmokers in stress and personalized health beliefs, but quitters maintained stronger beliefs in the psychological benefits of smoking than stable nonsmokers. Relapse was not associated with increases in stress or negative affect However, relapsers increased their positive beliefs about smoking and became indistinguishable from smokers in their beliefs. For quitters, decreased stress and negative beliefs about smoking may help maintain successful cessation. However, for relapsers, declining health risk perceptions may undermine future quit attempts.
