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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol and tobacco cessation in alcohol-dependent smokers: Analysis of real-time reports.

Alcohol-tobacco interactions and relapse precipitants were examined among alcohol-dependent smokers in a trial of concurrent alcohol and tobacco treatment. After discharge from treatment, participants completed 14 days of electronic diary (ED) assessments of mood, self-efficacy, urges to drink or smoke, and drinking and smoking behavior. ED data revealed an increase in frequency of alcohol urges after smoking episodes. Drinking relapse episodes were predicted by prior ED ratings of low self-efficacy to resist drinking and high urge to smoke. Smoking relapse episodes were predicted by high urge to smoke and high negative, high arousal mood. Results support a cross-substance cue reactivity model of multiple substance use and a limited-strength model, but not a cross-substance coping model.

Dynamic effects of self-efficacy on smoking lapses and relapse among adolescents.

Objective: The present study examined whether dynamic day-to-day variations in self-efficacy predicted success in quit attempts among daily smoking adolescents. Design: A sample of 149 adolescents recorded their smoking and self-efficacy three times per day during 1 week prior to and 3 weeks after a quit attempt. Main Outcome Measures: The first lapse, second lapse, and relapse after at least 24 hours of abstinence from smoking were the main outcome measures. Results: Self-efficacy was relatively high and moderately variable prior to the first lapse, but decreased and became more variable thereafter. Lower self-efficacy as measured at the lapse assessment significantly increased the risk that a second lapse and relapse would occur. Individual differences in baseline self-efficacy did not predict any of the treatment outcomes. The time-varying analyses, however, showed that lower self-efficacy on a given day predicted the first lapse, the second lapse, and relapse on the succeeding day. Daily concomitant smoking (any smoking on the preceding day) was not significantly related to relapse. Conclusion: The present results emphasize the importance of self-efficacy among adolescents in cessation and highlight the need for dynamic formulations and assessments of adolescents' self-efficacy and relapse.

Do resisted temptations during smoking cessation deplete or augment self-control resources?

A resource depletion model of self-control posits that for some period following performance of a task requiring self-control, self-control will be reduced and thus less available for use in a subsequent task. Using 2 substantial data sets collected in real time from individuals who were trying to quit smoking (1,660 and 9,516 temptation episodes collected from 61 and 248 individuals, respectively), we evaluated this model by testing the hypotheses that the number and length of resisted temptations and the intensity of the most recently reported urge during the prior 4 hr predict decreased self-control and increased likelihood of lapsing. Survival and multilevel regression modeling showed that contrary to the hypothesis, the number of recently resisted temptations predicted a lower risk of lapsing in both samples. Duration of resisted temptations had no significant effect in either sample. Intensity of most recently reported urge predicted lapsing in 1 data set but not in the other. Overall, there was little support for the resource depletion model. The protective effect of successfully resisting temptations was an unexpected but provocative finding.

Life before and after quitting smoking: An electronic diary study.

This article describes a multidimensional, multivariate, and multilevel approach to the assessment of nicotine withdrawal. In this prospective study, 70 adult smokers assigned to an active or placebo nicotine patch condition completed multiple daily assessments using an electronic diary. Average and individual growth curves were estimated for affective and nonaffective withdrawal symptoms. All symptoms but hunger increased significantly on the quit day and remained elevated for three weeks. Variability in symptom experiences across individuals increased from pre- to post-quit. Relations between symptom reports (e.g., negative affect or craving) and episodic events (e.g., stressful events or seeing someone smoke) changed from pre-quit to post-quit. Pre-quit increases in negative affect and quit-day increases in craving were inversely related to abstinence three months after the quit day, suggesting that anticipatory and immediate reactions to quitting influence success.

Situational temptation scores and smoking cessation in general care.

The construct of self-efficacy, which is assessed either in confidence- or temptation-related instruments, presumably predicts transitions between the transtheoretical model stages of change and ultimately smoking cessation outcome. To elucidate its predictive potential for smoking cessation in a general care setting, we examined the association of baseline scores of the situational temptations inventory with month 12 smoking status in 577 heavy smokers participating in a cluster-randomized study of physician training and financial incentives for smoking cessation in Germany. At follow-up, abstinence could be validated in 56 patients. The temptation sub- and total scores were not bivariately associated with altered odds of smoking cessation, in contrast to established predictors like the Fagerstrom test of nicotine dependence and the stages of change. They were associated with the Fagerstrom scores, but not with the stages of change. Controlling for both cessation predictors, in particular the positive/social temptation subscore was associated with quitting. Additional studies are needed to fully understand how situational temptations relate to smoking cessation outcomes and explain variance beyond that of more established predictors of cessation.

Evaluating reactivity to ecological momentary assessment during smoking cessation.

Ecological momentary assessment (EMA) consists of assessing phenomena in real time in the natural environment. EMA allows for more fine-grained analyses of addictive behavior and minimizes threats to internal validity, such as recall biases and errors. However, because of the intensive monitoring involved in EMA, measurement reactivity is a concern. To test whether EMA with palmtop personal computers induces reactivity, the authors compared smoking-related outcomes between smokers using EMA and those not using EMA during a quit attempt. The use of no-EMA control groups has been rare in reactivity investigations to date. The EMA protocol included event-contingent assessments (smoking episodes, urge episodes) and random assessments. Outcomes included biologically confirmed abstinence and self-report measures of withdrawal, self-efficacy, motivation, affect, and temptations. Participants were smokers motivated to quit (N = 96). They were randomized to 1 of 3 groups: EMA for the week preceding a planned quit date, EMA for the week following the quit date, and no EMA. Abstinence rates did not differ between the groups at Day 7 or at Day 28 postcessation. For the 20 subscales assessed at each of 3 assessment times, there were significant differences between participants with and without EMA experience for 3 subscales at the 1st of 3 assessment times, and significant differences for 3 different subscales at the 3rd assessment time. These differences suggest some reactivity to EMA, although the inconsistent pattern across time indicates that further research is needed to definitively conclude that EMA induces reactivity.

Using SMS text messaging to assess moderators of smoking reduction: Validating a new tool for ecological measurement of health behaviors.

Objective: Understanding the psychological processes that contribute to smoking reduction will yield population health benefits. Negative mood may moderate smoking lapse during cessation, but this relationship has been difficult to measure in ongoing daily experience. We used a novel form of ecological momentary assessment to test a self-control model of negative mood and craving leading to smoking lapse. Design: We validated short message service (SMS) text as a user-friendly and low-cost option for ecologically measuring real-time health behaviors. We sent text messages to cigarette smokers attempting to quit eight times daily for the first 21 days of cessation (N-obs = 3,811). Main outcome measures: Approximately every two hours, we assessed cigarette count, mood, and cravings, and examined between- and within-day patterns and time-lagged relationships among these variables. Exhaled carbon monoxide was assessed pre- and posttreatment. Results: Negative mood and craving predicted smoking two hours later, but craving mediated the mood–smoking relationship. Also, this mediation relationship predicted smoking over the next two, but not four, hours. Conclusion: Results clarify conflicting previous findings on the relation between affect and smoking, validate a new low-cost and user-friendly method for collecting fine-grained health behavior assessments, and emphasize the importance of rapid, real-time measurement of smoking moderators.

Examining Interrelationships Between Abstinence and Coping Self-Efficacy in Cocaine-Dependent Outpatients.

Initial abstinence and self-efficacy predict treatment outcome in cocaine-dependent outpatients. Associations between abstinence and coping self-efficacy were examined among cocaine-dependent outpatients (N=126). Abstinence was verified by urinalysis. Coping self-efficacy was measured using a modified Situational Confidence Questionnaire (SCQ; H. M. Annis, 1984). The modified SCQ had good validity and reliability, and scores increased during treatment. In bivariate analyses, early abstinence and SCQ scores each predicted subsequent abstinence and confidence during treatment and posttreatment follow-up. Based on structural equation modeling, early confidence was a significant predictor of later confidence but not of later abstinence, whereas early abstinence was a significant predictor of later abstinence and confidence. Results suggest a unidirectional relationship wherein prior abstinence predicts subsequent abstinence and confidence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does heightened affect make smoking cues more salient?

Negative affect (NA) states are robustly related to relapse. However, the mechanisms for this relationship are not well understood. Whereas most models have proposed that NA directly promotes lapsing, some models suggest that NA may promote lapses indirectly by increasing reactivity to smoking cues. This hypothesis was tested in secondary analyses of a study in which 248 smokers used ecological momentary assessment to self-monitor affective valence, smoking cues, and lapses during an attempt to quit smoking. The smoking cues the authors examined were others' smoking and consumption of alcohol or coffee. The odds of lapsing when exposed to smoking cues were compared across conditions of positive affect, neutral affect, and NA. Consistent main effects of affective valence were seen but not the hypothesized interaction. Indeed, analyses showed that the effect of cues was typically diminished under conditions of NA. No evidence was found to support the hypothesis that smoking cues and lapsing are more closely linked under NA conditions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-efficacy and smoking cessation: A meta-analysis.

According to relapse models, self-efficacy (SE), or confidence in one's ability to abstain, should predict the outcome of an attempt to quit smoking. We reviewed 54 studies that prospectively examined this relationship. The relationship between SE and future smoking depended upon the population studied and the timing of the SE assessment. The relationship between SE and future smoking was modest when SE was assessed prior to a quit attempt; SE scores were .21 standard deviation units (SD) higher for those not smoking at follow-up than for those who were smoking. The relationship was stronger (.47 SD) when SE was assessed post-quit. However, this effect was diminished when only abstainers at the time of the SE assessment were included in analysis (.28 SD). Controlling for smoking status at the time of SE assessment substantially reduced the relationship between SE and future smoking. Although SE has a reliable association with future abstinence, it is less robust than expected. Many studies may overestimate the relationship by failing to appropriately control for smoking behavior at the time of the SE assessment.

Smoking Withdrawal Dynamics: III. Correlates of Withdrawal Heterogeneity.

Five parameters of postcessation smoking withdrawal variability derived from clinical data (T. M. Piasecki, D. E. Jorenby, S. S. Smith, M. C. Fiore, & T. B. Baker, 2003a, 2003b) were predicted from baseline measures and pharmacotherapy assignment. Smokers who were more dependent, older, and high in negative affect reported more severe withdrawal. Women, heavier smokers, and those with a history of depression reported more variable symptoms. Smokers treated with nicotine patch, bupropion, or both reported less severe withdrawal than did those given placebo, but medication did not affect the slope of symptoms over time, day-to-day variability of symptoms, or the size of acute changes in symptoms associated with lapses to smoking. Prior research has shown that these symptom facets predict later relapse: thus, current pharmacotherapies may aid cessation by diminishing withdrawal severity, but they do not affect all clinically important aspects of withdrawal.

The instability of health cognitions: Visceral states influence self-efficacy and related health beliefs.

Objective: To determine how visceral impulses, such as hunger and drug craving, influence health beliefs. Design: The authors assessed smokers' self-efficacy and intentions to quit while in a randomly assigned state of cigarette craving or noncraving (Study 1), and assessed dieters weight-loss beliefs while hungry or satiated (Study 2). Main outcome measures: Self-efficacy, smoking cessation, weight-loss goals. Results: The authors found, in both the context of smoking and weight-loss, that participants in a cold (e.g., satiated) state had different health beliefs than participants in a hot state (e.g., hungry). Specifically, in Study 1, the authors found that smokers who experienced cigarette craving had lower self-efficacy than did satiated smokers. Consequently, smokers who craved a cigarette had less intention to quit smoking in the future compared with satiated smokers. In Study 2, the authors found that hungry dieters had less self-efficacy than did satiated dieters. This difference led hungry dieters to form less ambitious future weight-loss goals and view prior weight-loss attempts with more satisfaction. Conclusion: These findings contribute to our understanding of the nature of health beliefs and reveal that health beliefs are more dynamic than previously assumed.

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. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Specifying the determinants of the initiation and maintenance of behavior change: An examination of self-efficacy, satisfaction, and smoking cessation.

Using data from smokers (N = 591) who enrolled in an 8-week smoking cessation program and were then followed for 15 months, the authors tested the thesis that self-efficacy guides the decision to initiate smoking cessation but that satisfaction with the outcomes afforded by quitting guides the decision to maintain cessation. Measures of self-efficacy and satisfaction assessed at the end of the program, 2 months, and 9 months were used to predict quit status at 2, 9, and 15 months, respectively. At each point, participants were categorized as either initiators or maintainers on the basis of their pattern of cessation behavior. Across time, self-efficacy predicted future quit status for initiators, whereas satisfaction generally predicted future quit status for maintainers. Implications for models of behavior change and behavioral interventions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Contextual correlates of adolescents' self-efficacy after smoking cessation.

Recent research has shown that daily changes in self-efficacy predict lapses and relapse into smoking after quitting among adolescent daily smokers, but it is not known if and how momentary self-efficacy is associated with affect-motivational states and external contexts. In the present study, 134 adolescent daily smokers were monitored daily during 1 week prior to and 3 weeks after they began their quit attempt. Participants completed questions on smoking, self-efficacy, affect-motivational states (craving and negative affect), and external contexts (seeing others smoke, experiencing a stressful event, and alcohol and coffee consumption) three times a day. Affect-motivational states as well as all external contexts (except for coffee consumption) were associated with lower self-efficacy when participants were still abstinent, but also after they had lapsed. Associations between the situational contexts and self-efficacy did not largely depend on individual characteristics such as baseline self-efficacy and age. Among girls, however, the negative associations between self-efficacy and negative affect and drinking alcohol were found to be stronger. These results show that adolescents' self-efficacy during a quit attempt may be responsive to affect-motivational states and external contexts, both before and after lapsing.

Abstinence Self-Efficacy and Abstinence 1 Year After Substance Use Disorder Treatment.

To better understand the relationship between abstinence self-efficacy and treatment outcomes in substance use disorder patients, experts in the field need more information about the levels of abstinence self-efficacy most predictive of treatment outcomes. Participants (N = 2,967) from 15 residential substance use disorder treatment programs were assessed at treatment entry, discharge, and 1-year follow-up. A signal detection analysis compared the ability of different measures of self-efficacy to predict 1-year abstinence and identified the optimal cutoffs for significant predictors. The maximal level of abstinence self-efficacy (i.e., 100% confident) measured at discharge was the strongest predictor of 1-year abstinence. Treatment providers should focus on obtaining high levels of abstinence self-efficacy during treatment with the goal of achieving 100% confidence in abstinence.

Residual outcome expectations and relapse in ex-smokers.

From a social cognitive theoretical point of view, strong positive outcome expectations of smoking are a cause of relapse in smoking cessation, working in concert with self-efficacy. This study investigated whether and to what extent this could be verified in a sample of ex-smokers. Some (N=324) ex-smokers were followed for 7 months. At Time 1 (T1) and Time 2 (T2), participants filled in a self-report questionnaire assessing residual outcome expectations (ROEs), self-efficacy, craving for tobacco, and smoking behavior, which was sent and returned by mail. First, prospective analyses showed that ROEs assessed at T1 predicted relapse reported at T2 over and above self-efficacy. Second, the influence of ROEs (and self-efficacy) on relapse was mediated by craving experience. Third, the hypothesized interactions between ROEs and self-efficacy were significant and meaningful.

Mood variability and cigarette smoking escalation among adolescents.

The current study examined how affect dysregulation, as indexed via within-person negative mood variability, related to longitudinal patterns of smoking among adolescents. Students in the 8th and 10th grades (N = 517, 56% girls) provided data on cigarette use at baseline, 6-, and 12-month waves and provided ecological momentary assessments of negative moods via palmtop computers for 1 week at each wave. Mood variability was examined via the intraindividual standard deviations of negative mood reports at each wave. As predicted, high levels of negative mood variability at baseline significantly differentiated participants who escalated in their smoking behavior over time from participants who never progressed beyond low levels of experimentation during the course of the study. Mixed-effects regression models revealed that participants who escalated in their smoking experienced a reduction in mood variability as smoking increased, whereas participants with consistently high or low levels of cigarette use had more stable mood variability levels. Results suggest that high negative mood variability is a risk factor for future smoking escalation and that mood-stabilizing effects may reinforce and maintain daily cigarette use among youths.
