Effects of expectancies and coping on pain-induced motivation to smoke.

The prevalence of tobacco smoking among persons with recurrent pain is approximately twice that observed in the general population. Smoking has been associated with the development and exacerbation of several chronically painful conditions. Conversely, there is both experimental and cross-sectional evidence that pain is a potent motivator of smoking. A recent study provided the first evidence that laboratory-induced pain could elicit increased craving and produce shorter latencies to smoke (Ditre & Brandon, 2008). To further elucidate interrelations between pain and smoking, and to identify potential targets for intervention, in the current study, we tested whether several constructs derived from social–cognitive theory influence the causal pathway between pain and increased motivation to smoke. Smokers (N = 132) were randomly assigned to 1 of 4 conditions in this 2 × 2 between-subjects experimental design. Results indicated that manipulations designed to (a) challenge smoking-related outcome expectancies for pain reduction and (b) enhance pain-related coping produced decreased urge ratings and increased latencies to smoke, relative to controls. An unexpected interaction effect revealed that although each manipulation was sufficient to reduce smoking urges, the combination was neither additive nor synergistic. These findings were integrated with those of the extant literature to conceptualize and depict a causal pathway between pain and motivation to smoke as moderated by smoking-related outcome expectancies and mediated by the use of pain coping behaviors.

The effect of body image threat on smoking motivation among college women: Mediation by negative affect.

A recent experimental study found that activation of negative body image cognitions produced urges to smoke in young women (E. N. Lopez, D. J. Drobes, J. K. Thompson, & T. H. Brandon, 2008). This study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N = 133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and postmanipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation and that this effect occurs, at least in part, through increases in negative affect. Theoretical and applied implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol consumption, smoking urge, and the reinforcing effects of cigarettes: An ecological study.

Smokers (N=74) who volunteered for a smoking cessation study monitored their daily experiences for up to 6 weeks prior to the quit date. Self-reports from 7,707 diary records were used to examine the associations among alcohol consumption (present in 607 diary records), situational factors, smoking, urge to smoke, and subjective consequences of smoking. Alcohol use, smoking urge, and the subjective effects of smoking were context dependent. Momentary reports of smoking and alcohol consumption were associated with one another. Alcohol use predicted smoking even when contextual factors were covaried. Alcohol use was associated with more frequent reports of urge to smoke. Alcohol was also associated with more frequent reports that the last cigarette produced a rush/buzz, was good tasting, and reduced the urge. However, effects for rush/buzz and urge reduction were qualified by interactions between alcohol use and the latency since smoking. Rush/buzz tended to be associated with alcohol use, regardless of smoking recency. Alcohol was associated with urge reduction only when the cigarette being appraised was smoked more than 15 minutes prior to the diary entry.

Testing the influence of external and internal cues on smoking motivation using a community sample.

Exposing smokers to either external cues (e.g., pictures of cigarettes) or internal cues (e.g., negative affect induction) can induce urge to smoke and other behavioral and physiological responses. However, little is known about whether the two types of cues interact when presented in close proximity, as is likely the case in the real word. Additionally, potential moderators of cue reactivity have rarely been examined. Finally, few cue-reactivity studies have used representative samples of smokers. In a randomized 2 × 2 crossed factorial between-subjects design, the current study tested the effects of a negative affect cue intended to produce anxiety (speech preparation task) and an external smoking cue on urge and behavioral reactivity in a community sample of adult smokers (N = 175), and whether trait impulsivity moderated the effects. Both types of cues produced main effects on urges to smoke, despite the speech task failing to increase anxiety significantly. The speech task increased smoking urge related to anticipation of negative affect relief, whereas the external smoking cues increased urges related to anticipation of pleasure; however, the cues did not interact. Impulsivity measures predicted urge and other smoking-related variables, but did not moderate cue-reactivity. Results suggest independent rather than synergistic effects of these contributors to smoking motivation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affect, expectancies, urges, and smoking: Do they conform to models of drug motivation and relapse?

Social-learning models of drug motivation and relapse often include the constructs of affect and drug expectancies. Most research has taken a molar approach to examining relations between these constructs and level of drug use. An experiment examined the roles of affect and expectancies in multiple measures of situation-specific motivation to smoke tobacco. Undergraduate smokers (n?=?101) received either a positive or negative mood manipulation (false feedback on an intelligence test). Self-reported urge was influenced by both negative affect and expectancies for positive reinforcement from smoking. Actual consumption was related only to smoking expectancies and only among abstaining smokers. affect by expectancy interactions were also found. Findings support a limited role of affect and expectancies in smoking motivation. Poor coherence among the motivational indexes challenges the assumptions of existing models of drug motivation.

High-dose transdermal nicotine and naltrexone: Effects on nicotine withdrawal, urges, smoking, and effects of smoking.

Although treatment with transdermal nicotine replacement (TNR) has improved smoking abstinence rates, higher doses of TNR could improve effects on urge to smoke, nicotine withdrawal, and reinforcement from smoking, and naltrexone might further reduce reinforcement and urges. A laboratory investigation with 134 smokers using a 3 × 2 parallel-group design evaluated the effects of TNR (42-mg, 21-mg, or 0-mg patch) as crossed with a single dose of naltrexone (50 mg) versus placebo on urge to smoke, withdrawal, and responses to an opportunity to smoke (intake, subjective effects) after 10 hr of deprivation. Urge and withdrawal were assessed both prior to and after cigarette cue exposure. Only 42 mg TNR, not 21 mg, prevented urge to smoke, heart rate change, and cue-elicited increase in withdrawal. Both 21 and 42 mg TNR blocked cue-elicited drop in heart rate and arterial pressure. Naltrexone reduced cue-elicited withdrawal symptoms but not urges to smoke or deprivation-induced withdrawal prior to cue exposure. Neither medication significantly affected carbon monoxide intake or subjective effects of smoking except that 42 mg TNR resulted in lower subjective physiological activation. No interaction effects were found, and no results differed by gender. Results suggest that starting smokers with 42 mg TNR may increase comfort during initial abstinence, but limited support is seen for naltrexone during smoking abstinence.

Reactivity to instructed smoking availability and environmental cues: Evidence with urge and reaction time.

Reactivity to drug-related cues has been proposed as a possible mechanism to explain maintenance of drug use and relapse. This study examined whether cognitions associated with drug use (the belief that nicotine is available for use) also elicit reactivity. Smokers (N?=?132) were randomly assigned in a 2 (Smoking Availability)?×?2 (Smoking Stimuli) factorial design. Reactivity was measured by self-reported urge and probe reaction time. A main effect for availability was found in that participants who had been told that they could smoke shortly reported greater urges than those who had been told that smoking would not be permitted for 3 hr. Moreover, smoking-related stimuli produced increases in urge ratings only when participants had been told that smoking would be available shortly. Probe reaction time, in contrast, increased in the presence of smoking stimuli only when participants were told that cigarettes were unavailable. The theoretical and treatment implications of drug availability as a moderator of cue reactivity, as well as the utility of reaction time as an index of drug use motivation, are discussed.

How does coping help people resist lapses during smoking cessation?

Objectives: To determine whether types of coping strategies have differential effects on preventing lapses and lowering urge levels and to investigate mechanisms by which coping strategies prevent lapses during smoking cessation. Design: Sixty-one respondents performed ecological momentary assessment using palm-top computers and tape recorders to report their coping strategies and urge levels before and after temptations to smoke. Multilevel linear regression models were used to compare the effects of individual strategy types with the average strategy. Main Outcome Measures: Lapses versus resisted temptations and changes in urge levels. Results: Number of strategies significantly predicted resisting smoking and change in urge levels. Compared with the effect of the average strategy, movement/exercise was marginally worse at preventing lapses, and food/drink was marginally related to higher postcoping urge levels. Conclusion: Although using multiple coping strategies helps people resist the urge to smoke, no particular coping strategy works better than any other. Coping strategies prevent lapses by reducing high urge levels during temptations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of nicotine dose and administration method on withdrawal symptoms and side effects during short-term smoking abstinence.

The effects of using several different nicotine replacement treatments on self-reported withdrawal symptoms and side effects during 2-day periods of smoking cessation, with 5 days of ad lib smoking between cessation days, were evaluated. Participants (N ?=?18) experienced the following conditions: nicotine gum, 24-hr patch, 16-hr patch, 24-hr patch plus gum, double 24-hr patch, and no nicotine replacement. The present study found morning urge to smoke was greater during the 16-hr than during the 24-hr patch condition. Double-patch use resulted in significantly greater insomnia than the smoking baseline and 16-hr patch conditions. The no medication and gum alone conditions resulted in similar withdrawal symptoms, and both tended to result in greater reported withdrawal symptoms than the smoking baseline condition. There were no significant withdrawal symptom differences between the 24-hr, patch-gum, and double-patch conditions. The 24-hr and double-patch conditions were preferred by two thirds of the participants (6 each). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parental smoking cessation and child daily smoking: A 9-year longitudinal study of mediation by child cognitions about smoking.

Objective: This study investigated to what extent the prospective relationship between parental smoking cessation and child daily smoking is mediated by child cognitions about smoking. Design: The study drew its sample from the 40 Washington State school districts involved in the Hutchinson Smoking Prevention Project. The predictor variable of parental smoking cessation was measured during third grade. The mediator measures, consistent with the Theory of Planned Behavior and Social Cognitive Theory, were measured during ninth grade, and the smoking status outcome was measured during twelfth grade. Main Outcome Measures: Smoking status at twelfth grade. Results: Negative general attitudes toward smoking, attitude that cigarette smoke is bothersome, and tobacco refusal self-efficacy together significantly mediated 49% of the prospective relationship between parental smoking cessation and child daily smoking. Conclusion: Parental smoking cessation before children reach third grade may lead children to develop more negative cognitions about smoking, and, in turn, reduce their risk of smoking.

Cigarette smoking and chewing gum: Response to a laboratory-induced stressor.

The current study examined the anxiolytic effects of cigarette smoking and chewing gum on urge to smoke, withdrawal, and anxiety in response to a public speaking task in 45 undergraduate smokers. Participants were asked to smoke, chew gum, or do nothing in response to the stressor. Participants completed measures of anxiety, withdrawal symptoms, and urge to smoke pre- and poststressor. The smoke group reported fewer urges to smoke pre- and poststressor than the other groups. The smoke and gum groups reported fewer withdrawal symptoms than did the control group poststressor. Chewing gum was helpful in managing levels of withdrawal symptoms compared with the control group. Groups did not differ on measures of anxiety. Results suggest that smoking in response to a stressor may not reduce levels of affective stress. Furthermore, chewing gum may be helpful in managing withdrawal symptoms in response to a stressor.

Induction of smoking urge through imaginal and in vivo procedures: Physiological and self-report manifestations.

This experiment assessed reactivity to imaginal and in vivo smoking and control cues. One hundred current smokers were assessed during 2 sessions separated by a 6-hr interval, and half of the participants were abstinent from smoking over this interval. Verbal and physiological reactivity measures were selected based on their relevance for several models of urge. Results indicated that imaginal and in vivo smoking cues were equally effective at eliciting high levels of self-reported urges. Smoking deprivation led to a general enhancement in urge report, rather than a specific increase to smoking cues. Physiological responding differed somewhat as a function of urge induction method, although autonomic responses to smoking cues were uniformly consistent with the direct effects of nicotine. There was no relationship between verbal and physiological urge indices. Implications of the findings for several contemporary models of drug urges are discussed.

Is smoking automatic? Demands of smoking behavior on attentional resources.

The role of attention in the production of smoking behavior was investigated. Experienced and novice smokers were asked to perform a reaction time (RT) task under 4 conditions: while smoking (smoking), while mimicking all aspects of smoking except inhaling (pseudosmoking), while simply holding a cigarette (holding), and while not smoking (baseline). Experienced smokers' RTs increased during the pseudosmoking and holding conditions compared with baseline but did not differ between the smoking and baseline conditions, suggesting that attentional resources were not required for typical smoking behavior but were required to alter or inhibit smoking behavior. Novice smokers' RTs were slower during both the smoking and pseudosmoking conditions but not the holding condition, suggesting that novice smokers require the use of resources to smoke. Experiment 2 demonstrated that the differences in RT across conditions could not be explained by differences in urges. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of suppressing the urge to drink on smoking topography: A preliminary study.

Recent studies on the co-occurrent use of alcohol and tobacco have suggested that efforts to control the use of one substance may influence the use of the other. However, little is known about how cognitive strategies used to regulate the use of one substance may affect cross-substance use. In this study, 50 social drinkers who were daily smokers were exposed to the sight and smell of their favorite alcoholic beverage under instructions to either monitor or suppress their urge for alcohol. During a subsequent trial, participants were permitted to smoke while smoking topography was assessed. Although urge ratings were not influenced by instructional set, participants who had previously suppressed their urge to drink alcohol showed more intense smoking behavior than those who had monitored. Results are discussed in terms of the cross-substance effects of urge suppression and their implications for polysubstance treatment.

Situational Correlates of Abstinence Self-Efficacy.

Little is known about the situations that are associated with changes in self-efficacy during an attempt to quit smoking. In this study, 214 smokers used palmtop computers to record momentary self-efficacy ratings and situational context during a quit attempt. Higher urge to smoke and negative affect were associated with reduced self-efficacy. Although alcohol and coffee consumption are associated with heightened lapse risk, they were unrelated to abstinence self-efficacy. Individuals with low baseline self-efficacy generally reported lower self-efficacy across situations, but these differences were more pronounced under conditions of high urge and negative affect. These results suggest that self-efficacy may be reactive to affect-motivational states during a quit attempt. Whether these influences represent cognitive biases or objective risk assessments is not known. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of acute smoking exposure on the subsequent reinforcing value of smoking.

The reinforcing value of smoking (i.e., the degree to which a smoker will work to obtain smoking) after varying the magnitude of prior smoke exposure in smokers not trying to quit was examined. Eight men and 8 women participated in 5 sessions involving manipulation of prior exposure to smoking: 0, 2, 6, or 12 puffs after overnight smoking abstinence or ad-lib smoking before the session. After exposure, participants engaged in a computer task involving concurrent schedules of reinforcement for smoke puffs (16% all trials) versus money (4–64%). Only the greatest amount of prior exposure (ad lib) produced a significant reduction in subsequent responding for smoke puffs. No exposure condition significantly increased responding above that for 0 puffs, indicating no priming effect. By contrast, self-report measures of desire to smoke and amount of money participants would pay for a cigarette declined sharply with greater prior exposure. These measures were correlated only weakly with smoke-reinforced responding on the behavioral task, suggesting that subjective versus behavioral measures assess different dimensions of smoking's reward value.

Demographic factors in adult smoking status: Mediating and moderating influences.

In the current study mediators and moderators of demographic factors in smoking behavior were examined. Those with low education levels were more likely to smoke, believed less in the negative health effects of smoking, believed more in the positive psychological benefits of smoking, had lower value on a healthy lifestyle, and had more friends who smoked. Although all of these factors significantly mediated education effects on smoking, number of friends who smoke was the most powerful of these mediators. There were no gender differences in smoking rates. However, compared with men, smoking among women was more strongly related to perceived psychological benefits of smoking, number of friends who smoke, and health beliefs about smoking. Implications for targeting intervention at less educated individuals and women are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of Smoking Urge on Temporal Cognition.

The authors examined temporal aspects of smoking urge. In Experiment 1, smokers assigned to high- or low-urge conditions were informed they would be allowed to smoke in 2.5 min. They next completed measures of time perception. High-urge smokers reported 45 s to pass significantly more slowly than did low-urge smokers. In Experiment 2, the high-urge smokers from Experiment 1 anticipated that their urges would climb steadily over the next 45 min if they were not permitted to smoke. Another group of high-urge smokers actually reported their urges over 45 min. These urge ratings did not show the steady rise anticipated by the first group. Results suggest that smoking urge may affect time perception and that craving smokers overpredict the duration and intensity of their own future smoking urges if they abstain.

Smoking cues in a virtual world provoke craving in cigarette smokers.

Twenty smoking-deprived cigarette smokers participated in a study to test the ability of smoking cues within a virtual world to provoke self-reported craving to smoke. Participants were exposed to 2 virtual-reality simulations displayed on a computer monitor: a control environment not containing any intentional smoking stimuli and a cue-exposure environment containing smoking stimuli. At various points, participants rated their urge to smoke on a scale of 0-100. Results indicated that baseline urge ratings were equivalent in both conditions, but the maximum increase in urge ratings was significantly higher in the cue-exposure environment than in the control environment. This is comparable to what in vivo studies have reported, but with the advantage of simulating more naturalistic and complex settings in a controlled environment.
