Dynamic effects of self-efficacy on smoking lapse and relapse.

Self-efficacy (SE) is thought to be critical to success in smoking cessation both as an individual difference and as a dynamic process after a quit attempt. In this study, 214 smokers used palm-top computers to record day-to-day variations in SE during 4 weeks after quitting. SE remained at high and stable levels prior to a 1st lapse but decreased and became more variable thereafter. The authors used event history models with time-varying covariates to assess the effect of daily SE on lapse and relapse risk. Daily SE measures predicted an initial lapse on the subsequent day. However, this relationship was accounted for by stable baseline differences in SE (assessed by questionnaire), rather than by day-to-day dynamics in SE. Progression from 1st lapse to relapse was also examined. In this instance, daily SE predicted subsequent relapse risk, even when baseline SE and concurrent smoking were accounted for, suggesting the importance of SE dynamics for this stage of the relapse process.     

Dynamic self-efficacy and outcome expectancies: prediction of smoking lapse and relapse

According to social learning models of drug relapse, decreases in abstinence self-efficacy (ASE) and increases in positive smoking outcome expectancies (POEs) should foreshadow lapses and relapse. In this study, the authors examined this hypothesis by using ecological momentary assessment data from 305 smokers who achieved initial abstinence from smoking and monitored their smoking and their ASE and POEs by using palmtop computers. Daily ASE and POEs predicted the occurrence of a 1st lapse on the following day. Following a lapse, variations in daily ASE predicted the onset of relapse, even after controlling for concurrent smoking. ASE and POEs generally neither mediated nor moderated each other's effects. These data emphasize the role of dynamic factors in the relapse process.     

Experimental evidence for a causal relationship between smoking lapse and relapse

In this study, the authors prospectively evaluated the impact of a smoking lapse on relapse probability. After 4 days of smoking abstinence, 60 smokers were randomly assigned to smoke 5 nicotine-containing or 5 denicotinized cigarettes, or to remain abstinent (no lapse) during a 4-hr time period. Afterward, smoking abstinence was encouraged with monetary incentives, and smoking behavior was tracked for 6 days. Relative to the no-lapse condition, exposure to either of the cigarette types more than doubled the probability of subsequent smoking. Smoking outcomes did not differ between nicotine-containing and denicotinized cigarettes. The data suggest that stimulus factors may play an important role in lapse to relapse processes.     

Dynamic influences on smoking relapse process

This article describes a program of research applying Ecological Momentary Assessment (EMA) methods to study relapse to cigarette smoking, with a particular focus on the role of negative affect (NA) and self-efficacy (SE). Day-to-day changes in mood and stress did not predict lapse risk, but more proximal changes in affect were associated with lapses: Many lapses were marked by intense NA and by NA increases in the preceding hours. Individual differences in baseline SE predicted lapse risk, but daily SE was relatively stable during abstinence and did not influence lapse risk. However, lapses resulted in immediate drops in SE, and day-to-day changes in postlapse SE predicted progression to relapse, even after accounting for concurrent smoking. SE showed momentary drops associated with NA, but only among smokers with low baseline SE. Individual differences in baseline SE were only expressed situationally under conditions of NA. The findings highlight the importance of dynamic changes in background conditions and in immediate states as important influences on lapses and relapse and also suggest the importance of considering person by situation interactions.     

Predictors of risk for smoking relapse in men and women: A prospective examination

The current study examined whether prequit trait negative mood and smoking motives have different predictive patterns of smoking relapse in men and women. Thirty-three female (mean age ± SEM: 34.9 ± 2.5) and 38 male (mean age ± SEM: 37.1 ± 2.3) smokers interested in smoking cessation completed forms on smoking history, negative mood (i.e., depression, anxiety, and anger), stress, and smoking motives. Participants also provided samples for measurement of cotinine and carbon monoxide. Then, they set a quit date and were required to abstain from smoking at least for 24 hours. Participants were followed up for 12 months postcessation to measure their smoking status. Cox proportional hazard models revealed that motivation to reduce craving was a unique predictor of smoking relapse in men, while depressive mood, anxiety, anger, and perceived stress were predictive of time to relapse among women. These findings remained significant after statistically controlling for smoking-related variables, providing preliminary evidence that different factors may be associated with nicotine withdrawal and smoking relapse in men and women.

Positive reactions to tobacco predict relapse after cessation

Among chronic smokers, individual differences in subjective reactions to smoking may characterize important facets of nicotine dependence that relate to abstinence-induced craving, withdrawal symptom profiles, and risk for relapse. Although the negative reinforcing properties of smoking have achieved prominent positions in models of relapse (Baker, Brandon, & Chassin, 2004), vulnerability to relapse risk may also arise from seeking positive reinforcement from smoking (Shiffman & Kirchner, 2009). In this study, 183 cessation-motivated smokers provided subjective craving, positive and negative reactions to standardized cigarettes following overnight abstinence. Level of craving, negative mood, and positive mood after overnight abstinence were significantly predictive of withdrawal on quit-day. Increased positive reactions to smoking were uniquely predictive of relapse after quitting (Hazard Ratio = 1.22, p < .001). Individual differences in positive reactions to smoking may be important markers of neurobiological systems that promote dependence and interfere with cessation efforts.     

LISTENING TO NICOTINE:

Abstract— In recent years, theoretical models of drug motivation and drug dependence have downplayed the role of withdrawal symptoms in the maintenance of addiction. During this same period, strong links between drug use and measures of negative affect have been uncovered in empirical research. In this article we examine these trends in the context of research on smoking. Evidence is presented from two recent studies on smoking relapse that highlight the intimate connection between withdrawal symptomatology and negative affect Specifically, these studies reveal that (a) single-occasion measures of withdrawal symptoms or other markers of physical dependence do not contribute incremental validity in preceding relapse relative to measures of negative affect (b) the trajectory of withdrawal symptoms is highly idiosyncratic, (c) exacerbations cannot be tightly coupled with pharmacological events. (d) the temporal dynamics of withdrawal reflect fluctuations in negative affect, and (e) differences in the trajectory of withdrawal symptoms index relapse vulnerability. We conclude that a broadened view of withdrawal recognizing its probable affective bases will enhance its explanatory power and suggest new treatment strategies.     

Smoking withdrawal dynamics: I. Abstinence distress in lapsers and abstainers

Smoking withdrawal reports from a clinical trial (n = 893) were submitted to hierarchical linear modeling as a cross-method replication of a heterogeneity approach to withdrawal measurement and to clarify the influence of postcessation smoking on symptom reports. Five individual difference parameters tapping distinct facets of withdrawal were derived: intercepts (mean severity), linear slope (direction and rate of change), quadratic trend (curvature), volatility (scatter) and, among lapsers, a cigarette coefficent (smoking-related deflections of symptoms). All parameters were highly variable across persons. Lapsers had more aversive symptom patterns than abstainers, and symptoms tended to be higherthan otherwise predicted on lapse days. These results reinforce the conclusion that withdrawal symptoms are highly variable and argue against discarding withdrawal data from participants who lapse.     

Nature and role of change in anxiety sensitivity during NRT-aided cognitive-behavioral smoking cessation treatment

This study evaluated the associations between change in anxiety sensitivity (AS; fear of the negative consequences of anxiety and related sensations) and lapse and relapse during a 4-week group NRT-aided cognitive-behavioral Tobacco Intervention Program. Participants were 67 (44 women; M (age) = 46.2 years, SD = 10.4) adult daily smokers. Results indicated that participants who maintained high levels of AS from pretreatment to 1 month posttreatment, compared to those who demonstrated a significant reduction in AS levels during this time period, showed a significantly increased risk for lapse and relapse. Further inspection indicated that higher continuous levels of AS physical and psychological concerns, specifically among those participants who maintained elevated levels of AS from pre- to posttreatment, predicted significantly greater risk for relapse. Findings are discussed with respect to better understanding change in AS, grounded in an emergent taxonic-dimensional factor mixture model of the construct, with respect to lapse and relapse during smoking cessation.     

Prospective analysis of early lapse to drinking and smoking among individuals in concurrent alcohol and tobacco treatment

The aims of the current study were to examine, prospectively, (a) dynamic changes in affective state, self-efficacy, and urge in the hours before initial smoking and drinking lapses among individuals in concurrent alcohol and smoking treatment, and (b) the extent to which self-efficacy, urge to use, and/or the use of one substance predicted lapse to the other substance. Ninety-six men and women recruited for a clinical trial of concurrent alcohol and tobacco treatment were eligible for inclusion. Only data from those who experienced an initial lapse to drinking (n=29) or smoking (n=32) were included. Two outpatient substance abuse clinics provided concurrent alcohol and smoking treatment on a weekly basis for three months. Ecological Momentary Assessment (EMA) methods were employed over a 28-day monitoring period to assess antecedents to first drink, and a 14-day monitoring period was examined for initial smoking lapses. Baseline and EMA measures of positive and negative affect, alcohol/smoking urge, alcohol/smoking abstinence self-efficacy, nicotine withdrawal, and quantity/frequency of alcohol and tobacco use were examined as lapse predictors. Analyses of EMA ratings controlled for the corresponding baseline measure. Smoking lapse among individuals in concurrent alcohol and tobacco treatment was foreshadowed by higher urges to smoke, lower positive mood, and lower confidence to resist smoking. Drinking lapse was preceded by lower confidence to resist smoking, but only among individuals who reported recent smoking. Concurrent alcohol and smoking treatment should focus on the enhancement of abstinence self-efficacy, positive mood, and the curbing of urges in order to offset lapse risk.     

Nature and Role of Change in Anxiety Sensitivity During NRT-Aided Cognitive-Behavioral Smoking Cessation Treatment

This study evaluated the associations between change in anxiety sensitivity (AS; fear of the negative consequences of anxiety and related sensations) and lapse and relapse during a 4-week group NRT-aided cognitive-behavioral Tobacco Intervention Program. Participants were 67 (44 women; M _age = 46.2 years, SD = 10.4) adult daily smokers. Results indicated that participants who maintained high levels of AS from pretreatment to 1 month posttreatment, compared to those who demonstrated a significant reduction in AS levels during this time period, showed a significantly increased risk for lapse and relapse. Further inspection indicated that higher continuous levels of AS physical and psychological concerns, specifically among those participants who maintained elevated levels of AS from pre- to posttreatment, predicted significantly greater risk for relapse. Findings are discussed with respect to better understanding change in AS, grounded in an emergent taxonic-dimensional factor mixture model of the construct, with respect to lapse and relapse during smoking cessation.     

Relapse dynamics during smoking cessation: recurrent abstinence violation effects and lapse-relapse progression

Smoking cessation is a process that unfolds over time and is characterized by intermittent lapses. We used parametric recurrent event survival analyses to better understand the dynamic relationship between a set of Abstinence Violation Effect (AVE, Marlatt & Gordon, 1985) responses to lapsing and subsequent lapse-relapse progression. Participants were 203 smokers who achieved abstinence and responded to items assessing three core components of the AVE (internal attribution, abstinence self-efficacy and guilt) following a total of 1,001 lapse episodes in near real time. Neither self-blame, self-efficacy, nor guilt following participants' first lapse predicted relapse. Controlling for responses to their first lapse, responses to each additional lapse did prospectively predict lapse progression, such that drops in self-efficacy were associated with accelerated progression to a subsequent lapse (HR = 1.09, CI = 1.02-1.15), while increases in internal attributions of blame actually protected against lapsing (HR = 0.98, CI = 0.97-0.99). Treatment with nicotine patches slowed recurrent lapse progression (HR = 0.58, CI = 0.48-0.70), but this effect dissipated over multiple lapses, and was moderated by elevated ratings of postlapse guilt (HR = 1.08, CI = 1.01-1.18), which predicted accelerated progression within the active patch group, while protecting against lapse in the placebo group. Results highlight the dynamic nature of lapse responses during smoking cessation, indicating that self-efficacy predicts progression from one lapse to the next, while attributions of self-blame and guilt influenced progression in unexpected ways.     

Smoking withdrawal dynamics in unaided quitters

Considerable research shows that withdrawal severity is inconsistently related to smoking cessation outcomes. This may result from measurement problems or failure to scrutinize important dimensions of the withdrawal experience. Two recent studies demonstrated that withdrawal elevation and variations in the time course of withdrawal were related to relapse in smokers treated with the nicotine patch (T. M. Piasecki, M. C. Fiore, & T. B. Baker, 1998). This article reports a conceptual replication and extension of those findings in unaided quitters. Evidence for temporal heterogeneity was found across different types of withdrawal symptoms. Patterns or slopes of affect and urge reports over time predicted smoking status at follow-up, as did mean elevation in withdrawal symptoms. These results suggest that affect and urge withdrawal symptoms make independent contributions to relapse and that relapse is related to both symptom severity and trajectory.     

Distress tolerance and duration of past smoking cessation attempts

The present study tested the hypothesis that limited ability to tolerate physical and psychological distress is associated with early relapse from smoking cessation. Specifically, the authors exposed 16 current smokers who had failed to sustain any previous quit attempt for more than 24 hr (immediate relapsers) and 16 smokers with at least 1 sustained quit attempt of 3 months or longer (delayed relapsers) to psychological (mental arithmetic) and physical (carbon dioxide inhalation-breath holding) stressors. Relative to delayed relapsers, immediate relapsers were characterized by higher baseline levels of affective vulnerability, by greater levels of dysphoria and urge to smoke after 12 hr of nicotine deprivation, and by less task persistence on the stressors, suggesting that these may be risk factors for early lapse in the context of quitting smoking.     

Using mediational models to explore the nature of tobacco motivation and tobacco treatment effects

Various theories have proposed mechanisms for drug motivation and relapse. For instance, negative reinforcement theories focus on the alleviation of withdrawal. However, other theories and some data cast doubt on the importance of withdrawal as a motivator of addictive drug use. Using data from a randomized double-blind placebo-controlled smoking cessation treatment study (N=608), this research examined the impact of withdrawal on drug motivation and the ability to maintain abstinence. Withdrawal was experimentally manipulated by randomly assigning participants to receive active bupropion versus placebo. Mediation analyses revealed that active bupropion reduced the amount of withdrawal and craving that individuals reported in the 1st week post quit; modest support was also found for smaller declines in positive affect. These effects, in turn, were all positively associated with posttreatment abstinence. These results implicate withdrawal as an important factor in motivating persistent tobacco use.     

Acute nicotine reinforcement, but not chronic tolerance, predicts withdrawal and relapse after quitting smoking.

Little research has examined the association of tobacco dependence with nicotine tolerance or reinforcement in a clinical sample. Smokers preparing to quit smoking participated in laboratory sessions to assess nicotine tolerance on subjective, cardiovascular, and performance measures and to assess nicotine reinforcement using a choice procedure. Participants were then provided with individual counseling (but no medication), made a quit attempt, and were followed for 1 year to determine clinical outcome, as determined by postquit withdrawal and days to relapse. Nicotine tolerance was unrelated to either withdrawal or relapse. However, acute nicotine reinforcement was significantly related to both greater withdrawal and faster relapse. Results challenge the common assumption that nicotine tolerance is closely related to dependence but suggest that nicotine reinforcement may have theoretical and clinical significance for dependence.     

Attentional bias predicts outcome in smoking cessation.

Most attempts to quit smoking end in failure, with many quitters relapsing in the first few days. Responses to smoking-related cues may precipitate relapse. A modified emotional Stroop task-which measures the extent to which smoking-related words disrupt performance on a reaction time (RT) task-was used to index the distracting effects of smoking-related cues. Smokers (N = 158) randomized to a high-dose nicotine patch (35 mg) or placebo patch completed the Stroop task on the 1st day of a quit attempt. Smokers using an active patch exhibited less attentional bias, making fewer errors on smoking-related words. Smokers who showed greater attentional bias (slowed RT on the first block of smoking words) were significantly more likely to lapse in the short-term, even when controlling for self-reported urges at the test session. Attentional bias measures may tap an important component of dependence.     

LISTENING TO SMOKING RESEARCHERS:

Abstract— The work of Baker and his colleagues indicates that a broadened view of withdrawal that recognizes its probable affective bases will suggest new treatment strategies for the treatment of smoking and, by extension, drug dependence. This commentary briefly reviews the current status of treating drug dependence by addressing negative affect and emphasizes that clinical research which allows for building more complex models, of individual change over time holds promise for clearer understanding of the role of negative affect among drug abusers and thus more effective treatments. Although clinical treatments for drug dependence have long recognized the significance of negative affect we are far from a thorough understanding of the role of negative affect in withdrawal, craving, and relapse to drug use.     

Social influences on smoking in middle-aged and older women

The purpose of this study was to examine the role of 2 types of social influence--general social support and living with a smoker--on smoking behavior among middle-aged and older women in the Women's Health Initiative (WHI) Observational Study. Participants were postmenopausal women who reported smoking at some time in their lives (N=37,027), who were an average age of 63.3 years at baseline. Analyses used multiple logistic regression and controlled for age, educational level, and ethnicity. In cross-sectional analyses, social support was associated with a lower likelihood and living with a smoker was associated with a higher likelihood of being a current smoker and, among smokers, of being a heavier smoker. Moreover, in prospective analyses among baseline smokers, social support predicted a higher likelihood and living with a smoker predicted a lower likelihood of smoking cessation 1-year later. Further, in prospective analyses among former smokers who were not smoking at baseline, social support predicted a lower likelihood and living with a smoker predicted a higher likelihood of smoking relapse 1-year later. Overall, the present results indicate that social influences are important correlates of smoking status, smoking level, smoking cessation, and smoking relapse among middle-aged and older women.     

A comparison of alternative theoretical approaches to smoking cessation and relapse

Two theoretical approaches to smoking cessation were compared. Participants were randomly assigned either to (a) a traditional treatment program that used contingency contracting and that emphasized the necessity for absolute abstinence (AA) or to (b) a relapse-prevention (RP) treatment that focused on gradual acquisition of nonsmoking skills. It was hypothesized that participants in the RP treatment would be less successful initially but would have better maintenance skills and thus would relapse less during a 1-year follow-up period. Each program was evaluated in two formats: group-based treatment and self-help materials. Results indicated comparable 1-year abstinence rates for all treatments, although more participants dropped out of the self-help formats. Participants in the RP intervention were more likely to lapse sooner after quitting and were more likely to quit again during the 1-year maintenance period. Exploratory analyses of successful participants suggested that women were more successful in the RP program and that men had greater success with the AA approach.
