Negative mood, depressive symptoms, and major depression after smoking cessation treatment in smokers with a history of major depressive disorder.

Negative mood, depressive symptoms, and major depressive episodes (MDEs) were examined in 179 smokers with a history of major depression in a trial comparing standard smoking cessation treatment to treatment incorporating cognitive-behavioral therapy for depression (CBT-D). Early lapses were associated with relatively large increases in negative mood on quit date. Mood improved in the 2 weeks after quit date among those returning to regular smoking but not among those smoking moderately. Continuous abstinence was associated with short- and long-term reductions in depressive symptoms. MDE incidence during follow-up was 15.3% and was not associated with abstinence. Unexpected was that CBT-D was associated with greater negative mood and depressive symptoms and increased MDE risk. Results suggest complex bidirectional associations between affect and smoking outcomes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Concurrent brief versus intensive smoking intervention during alcohol dependence treatment.

Alcohol dependent smokers (N=118) enrolled in an intensive outpatient substance abuse treatment program were randomized to a concurrent brief or intensive smoking cessation intervention. Brief treatment consisted of a 15-min counseling session with 5 min of follow-up. Intensive intervention consisted of three 1-hr counseling sessions plus 8 weeks of nicotine patch therapy. The cigarette abstinence rate, verified by breath carbon monoxide, was significantly higher for the intensive treatment group (27.5%) versus the rate for the brief treatment group (6.6%) at 1 month after the quit date but not at 6 months, when abstinence rates fell to 9.1% for the intensive treatment group and 2.1% for the brief treatment group. Smoking treatment assignment did not significantly impact alcohol outcomes. Although intensive smoking treatment was associated with higher rates of short-term tobacco abstinence, other, perhaps more intensive, smoking interventions are needed to produce lasting smoking cessation in alcohol dependent smokers.

A longitudinal analysis of unaided smoking cessation.

A sample of 153 smokers who attempted to quit smoking without treatment was followed for 2 years. Follow-up assessment occurred at 1 month, 4 months, 1 year, and 2 years postquit. A subsample of 69 individuals was also interviewed prior to their quit date. The majority of participants (77%) achieved at least 24 hr of abstinence by the 1-month follow-up. However, subsequent relapse rates were high: Only 13% of the sample was abstinent at 1 year, and 19% reported abstinence at the 2-year follow-up. Variables related to short-term outcome were generally unrelated to long-term outcome. Individuals who succeeded at initial cessation were more likely to be men and to be lighter smokers. Among those who initially quit, abstainers at 1 month were less likely to have participated in prior treatment, to report smokers among their friends, and to live with other smokers. At 2 years, abstainers were younger and had smoked for fewer years. The use of multiple strategies for cessation was associated with abstinence at the 2-year follow-up. A strong motivation to quit was found to be important for both initial success and long-term maintenance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Randomized controlled trial of behavioral activation smoking cessation treatment for smokers with elevated depressive symptoms.

Objective: Depressive symptoms are associated with poor smoking cessation outcomes, and there remains continued interest in behavioral interventions that simultaneously target smoking and depressive symptomatology. In this pilot study, we examined whether a behavioral activation treatment for smoking (BATS) can enhance cessation outcomes. Method: A sample of 68 adult smokers with mildly elevated depressive symptoms (M = 43.8 years of age; 48.5% were women; 72.7% were African American) seeking smoking cessation treatment were randomized to receive either BATS paired with standard treatment (ST) smoking cessation strategies including nicotine replacement therapy (n = 35) or ST alone including nicotine replacement therapy (n = 33). BATS and ST were matched for contact time and included 8 sessions of group-based treatment. Quit date was assigned to occur at Session 4 for each treatment condition. Participants completed a baseline assessment; furthermore, measures of smoking cessation outcomes (7-day verified point-prevalence abstinence), depressive symptoms (Beck Depression Inventory–II; Beck, Steer, & Brown, 1996), and enjoyment from daily activities (Environmental Reward Observation Scale; Armento & Hopko, 2007) were obtained at 1, 4, 16, and 26 weeks post assigned quit date. Results: Across the follow-ups over 26 weeks, participants in BATS reported greater smoking abstinence (adjusted odds ratio = 3.59, 95% CI [1.22, 10.53], p = .02) than did those in ST. Participants in BATS also reported a greater reduction in depressive symptoms (B = ?1.99, SE = 0.86, p = .02) than did those in ST. Conclusions: Results suggest BATS is a promising intervention that may promote smoking cessation and improve depressive symptoms among underserved smokers of diverse backgrounds.

Depressive symptoms and readiness to quit smoking among cigarette smokers in outpatient alcohol treatment.

The authors examined whether length of alcohol abstinence and depressive symptoms were related to motivational readiness to consider smoking cessation among patients in alcohol treatment. Participants were adults (N = 253) enrolled in a smoking cessation trial. Controlling for gender, depressive symptoms, and nicotine dependence, hierarchical regression analysis of readiness scores revealed a significant interaction of days since last drink and depressive symptoms. It was found that a greater number of days since last drink was associated with greater readiness, but only among patients with low scores on the Center for Epidemiologic Studies Depression Scale (L. S. Radloff, 1977). The findings suggest that alcoholic smokers with low depressive symptoms are more receptive to quitting smoking after sustained alcohol abstinence.

Need for cognition as a predictor and a moderator of outcome in a tailored letters smoking cessation intervention.

Objective: To analyze whether baseline need for cognition (NFC) was a predictor or a moderator of treatment outcome in a tailored letters intervention for smoking cessation. Design: A total of 1,499 daily smokers were recruited from general medical practices in Germany within a quasi-randomized trial testing the efficacies of two brief interventions for smoking cessation: (a) computer-generated tailored letters and (b) physician-delivered brief counseling versus assessment-only. For this study, we used data from 1,097 daily smokers who were assigned to the tailored letters or the assessment-only condition. Main Outcome Measures: self-reported 6-month prolonged abstinence from tobacco smoking assessed at 12-, 18-, and 24-month follow-ups, and smoking cessation self-efficacy assessed at 6- and 24-month follow-ups. Results: Baseline NFC predicted 6-month prolonged smoking abstinence (p = .01) and smoking cessation self-efficacy (p .05) but on smoking cessation self-efficacy (p = .05). Tailored letters resulted in higher smoking cessation self-efficacy only for persons with higher NFC. Conclusion: Higher levels of NFC are required to increase smoking cessation self-efficacy in computer-tailored interventions for smoking cessation. Considering an individual's NFC might improve the efficacy of written interventions for smoking cessation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Patterns of change in depressive symptoms during smoking cessation: Who's at risk for relapse?

The authors examined patterns of change in depressive symptoms during smoking cessation treatment in 163 smokers with past major depressive disorder (MDD). Cluster analysis of Beck Depression Inventory (A. T. Beck, C. H. Ward, M. Mendelson, J. Mock, & J. Erbaugh, 1961) scores identified 5 patterns of change. Although 40% of participants belonged to clusters characterized by increasing depressive symptoms during quitting (rapid increasers, n=31, and delayed increasers, n=35), almost 47% were in clusters characterized by decreasing symptoms (delayed decreasers, n=24, and rapid decreasers, n=52). Both rapid and delayed increasers had especially poor smoking cessation outcomes. Results suggest that among smokers with an MDD history there is substantial heterogeneity in patterns of depressive symptoms during quitting and that patterns involving increased symptoms are associated with low abstinence rates.

A controlled smoking cessation trial for substance-dependent inpatients.

Smoking treatment for newly recovering drug and alcohol-dependent smokers in a residential rehabilitation program was examined. The randomly assigned conditions (n?=?50 each) were multicomponent smoking treatment (MST), MST plus generalization training of smoking cessation to drug and alcohol cessation (MST+G), or usual care (UC). Fifty participants who declined smoking treatment (treatment refusers) also were studied. Both treatment conditions achieved continuous smoking abstinence rates (MST: 12%. MST+G: 10%, at 12-month follow-up) that were significantly higher than in the UC condition (0%). The MST condition had a continuous drug and alcohol abstinence rate that was significantly higher than that of the MST+G condition (40% vs. 20% at 12-month follow-up) although neither differed significantly from that of the UC condition (33%). These results support the feasibility of smoking treatment for this population and provide information regarding appropriate treatment components.

Characterizing nicotine withdrawal in pregnant cigarette smokers.

Maternal smoking is a leading preventable cause of poor pregnancy outcomes and infant morbidity and mortality. Whereas pregnancy has been thought of as a "window of opportunity" when women are more motivated to change health behaviors such as smoking, only 20% of pregnant women quit smoking upon learning they are pregnant and remain abstinent at the end of the pregnancy. Greater understanding of possible obstacles to smoking during pregnancy, such as nicotine withdrawal, is needed. The symptoms of nicotine withdrawal have been well characterized in nonpregnant smokers, but there has been only 1 report conducted during pregnancy, and that was a retrospective study. The aim of the present study was to characterize nicotine withdrawal and craving in pregnant cigarette smokers. These data were collected as part of prospective clinical trials assessing the efficacy of voucher-based incentives to promote abstinence from cigarette smoking during pregnancy and postpartum. The authors examined results from the Minnesota Nicotine Withdrawal Scale (J. R. Hughes & D. K. Hatsukami, 1998) in 27 abstainers (reported no or very low levels of smoking, which was confirmed biochemically) and 21 smokers (smoked at >80% of their baseline smoking level) during the first 5 days of a cessation attempt. Abstainers reported more impatience, anger, and difficulty concentrating than did smokers. The results also suggest that pregnant smokers generally may have elevated baseline levels of withdrawal, which need to be considered in the design and analysis of future studies.

An investigation of predictors of nicotine abstinence in a smoking cessation treatment study of smokers with a past history of alcohol dependence.

This study investigated predictors for smoking abstinence at 12-week follow-up among 85 smokers with a past history of alcohol dependence enrolled in a smoking cessation trial. Length of alcohol abstinence at time of enrollment and longest previous period of smoking abstinence were significantly associated with smoking status at follow-up. Multiple logistic regression with these variables entered as predictors suggested that longest previous period of smoking abstinence partially mediated the relationship between length of alcohol abstinence at enrollment and smoking status at follow-up. Additional research is warranted to identify predictors of nicotine abstinence and smoking relapse in this population and to understand the factors that mediate the relationship between length of alcohol abstinence at enrollment and smoking outcome.

Effect of Bupropion on Depression Symptoms in a Smoking Cessation Clinical Trial.

Bupropion is an antidepressant shown to be efficacious for smoking cessation. This study examined the short- and long-term effects of bupropion (300 mg/day for 10 weeks) versus placebo on depression symptoms among 497 smokers attempting to quit in a randomized trial of bupropion plus behavioral counseling. Depression symptoms were assessed via the Center for Epidemiological Studies Depression Scale (L. Radloff, 1977) at baseline, end of treatment, and at 6-month follow-up. Baseline nicotine dependence level was assessed with the Fagerstrom Test for Nicotine Dependence (T. F. Heatherton, L. T. Kozlowski, R. C. Frecker, & K. O. Fagerstr?m, 1991). A regression model of depression symptoms demonstrated a significant interaction between nicotine dependence and treatment for the treatment phase and during follow-up. Depression symptoms did not mediate the effects of bupropion on abstinence at either time point. Highly nicotine-dependent smokers who receive bupropion are more likely to experience a decrease in depressive symptoms during active treatment but are also more likely to experience a rebound in depressive symptoms when bupropion is discontinued.

Effects of an intensive depression-focused intervention for smoking cessation in pregnancy.

Objective: The objective of this study was to evaluate a depression-focused treatment for smoking cessation in pregnant women versus a time and contact health education control. We hypothesized that the depression-focused treatment would lead to improved abstinence and reduced depressive symptoms among women with high levels of depressive symptomatology. No significant main effects of treatment were hypothesized. Method: Pregnant smokers (N = 257) were randomly assigned to a 10-week, intensive, depression-focused intervention (cognitive behavioral analysis system of psychotherapy; CBASP) or to a time and contact control focused on health and wellness (HW); both included equivalent amounts of behavioral and motivational smoking cessation counseling. Of the sample, 54% were African American, and 37% met criteria for major depression. Mean age was 25 years (SD = 5.9), and women averaged 19.5 weeks (SD = 8.5) gestation at study entry. We measured symptoms of depression using the Center for Epidemiological Studies–Depression Scale (Radloff, 1977). Results: At 6 months posttreatment, women with higher levels of baseline depressive symptoms treated with CBASP were abstinent significantly more often, F(1, 253) = 5.61, p = .02, and had less depression, F(1, 2620) = 10.49, p = .001, than those treated with HW; those with low baseline depression fared better in HW. Differences in abstinence were not retained at 6 months postpartum. Conclusions: The results suggest that pregnant women with high levels of depressive symptoms may benefit from a depression-focused treatment in terms of improved abstinence and depressive symptoms, both of which could have a combined positive effect on maternal and child health.

A multimodal approach to assessing the impact of nicotine dependence, nicotine abstinence, and craving on negative affect in smokers.

We used multimodal measurement to evaluate whether (a) nicotine dependence is associated with baseline and postquit negative affect and craving, (b) smoking relapse is associated with greater negative affect and craving than abstinence, and (c) craving is associated with negative affect. Treatment-seeking smokers were randomly assigned to either a brief behaviorally based smoking-cessation treatment condition or to a delayed treatment control condition. Participants in the treatment condition attended four assessment sessions, 4–5 days prequit (baseline), 1–2 days postquit, 3–5 days postquit, and 10–14 days postquit, while controls attended four sessions spaced over the same intervals. Retrospective questionnaires were collected at the beginning of each session, and corrugator EMG and in-session ratings were collected during viewing of affective and cigarette-related slides. The multimodal measures indicated that more dependent smokers experienced greater negative affect and craving at baseline and postquit, regardless of abstinence status. The self-report measures indicated that both relapsed and abstinent smokers reported greater negative affect and craving than control smokers. Craving was associated with negative affect across measurement modalities. These results highlight the benefits of using multimodal measures to study the impact of nicotine dependence and withdrawal on negative affect and craving.

Eating orientation, postcessation weight gain, and continued abstinence among female smokers receiving an unsolicited smoking cessation intervention.

Predictors of weight gain following smoking cessation were assessed among 1,219 female smokers enrolled in a health maintenance organization. Women randomized to the treatment group received a cessation intervention without regard to their interest in quitting smoking. It was hypothesized that cessation would result in subsequent weight gain and postcessation weight gain would be associated with scores on a modified Restraint Scale, the Disinhibition Scale, and a scale assessing tendency to eat during periods of negative affect. Persons who abstained from smoking over the 18-month study gained more weight than did intermittent smokers and continuous smokers, and among 762 women who reported at least 1 on-study attempt to quit smoking, 36% gained weight. Weight gain was associated with disinhibited eating and negative affect eating but not with restrained eating. Weight gain also was associated with continued abstinence from smoking.

Baseline reaction time predicts 12-month smoking cessation outcome in formerly depressed smokers.

Burgeoning evidence points to a positive association between cigarette smoking and depression. Moreover, depressive symptomatology, whether historical, current, or subsyndromal, appears to negatively influence smoking cessation efforts. Whereas depression is typically assessed via clinical interview or self-report, rarely are the known neurocognitive deficits linked to depression (e.g., global slowing) assessed in the context of smoking cessation research. Hence, this study examined whether simple reaction time--color naming of affectively neutral words--is predictive of 12-month smoking cessation outcome among a sample of formerly depressed smokers (N = 28). Results revealed a significant, positive correlation between reaction time and depressive symptoms such that those who exhibited slower reaction times were at heightened risk to relapse. Baseline depressive symptoms, as assessed via self-report, neither correlated with nor predicted smoking cessation outcome. Results from logistic regression analyses further showed that reaction time added incremental variance to the prediction of smoking cessation outcome. Therefore, simple reaction time may capture aspects of depression not typically assessed in self-report questionnaires. These results are discussed in terms of their theoretical and clinical implications for smoking cessation research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long-term effectiveness of two Dutch work site smoking cessation programs

This article reports on one of the few experimental studies in Europe to examine work site smoking cessation. The study examined whether a comprehensive intervention (self-help manuals, group courses, a mass media campaign, smoking policies, and a second-year program) is more effective than a minimal intervention (self-help manuals only). Eight work sites participated in the study. The effect of treatment on smoking cessation depended on nicotine dependency levels: Heavy smokers had more success with the comprehensive smoking cessation intervention than with the minimal intervention (with respect to both 14-month quit rate and 6-month prolonged abstinence). For heavy smokers, exposure to mass media exhibitions or to group courses had a beneficial effect on prolonged abstinence. Comprehensive programs may be most appropriate in Dutch work sites with large proportions of heavily addicted smokers.     

Cue-Provoked Craving and Nicotine Replacement Therapy in Smoking Cessation.

Cue exposure paradigms have been used to examine reactivity to smoking cues. However, it is not known whether cue-provoked craving is associated with smoking cessation outcomes or whether cue reactivity can be attenuated by nicotine replacement therapy (NRT) in clinical samples. Cue-provoked craving ratings and reaction time responses were measured on the 1st day of abstinence among 158 smokers who had been randomized to high-dose nicotine (35 mg) or placebo patch. The nicotine patch reduced overall levels of craving but did not attenuate cue-provoked craving increases or reaction time responses. Cue-provoked craving predicted relapse among participants on the nicotine patch but not among those on placebo. In summary, NRT users could benefit from treatment that attenuates cue-provoked craving. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A preliminary investigation of rapid smoking as a lapse-responsive treatment for tobacco dependence.

Lapses within the first 2 weeks of a smoking cessation attempt are strongly associated with a return to regular smoking (S. L. Kenford et al., 1994). Unfortunately, little is known about how to prevent an initial lapse from progressing to a full relapse, and presently there are no validated lapse-responsive therapeutic interventions. The present study tested the efficacy and feasibility of rapid smoking plus counseling as a novel lapse-responsive intervention. Sixty-seven participants enrolled in a smoking treatment program involving brief counseling and a 9-week course of bupropion. Beginning on the quit day, participants' smoking behavior was tracked daily for 14 days. Once an early smoking lapse was identified, participants were randomly assigned to receive either 3 sessions of rapid smoking plus counseling or no intervention (usual care). Consistent with previous research, participants who smoked during the first 2 weeks of the quit attempt had significantly poorer 6-month outcomes (3% abstinent) than did those who did not smoke (64% abstinent). Compared with early abstainers, early lapsers were more nicotine dependent and reported greater cravings and lower confidence in their ability to abstain from smoking during the first 48 hours of abstinence. As expected, rapid smoking produced a variety of aversive effects, including increased nausea, dizziness, and vomiting as well as sharply decreased cravings to smoke. However, rapid smoking did not improve abstinence outcomes relative to usual care. Although rapid smoking has been shown to be an effective treatment for initial smoking cessation, in this preliminary study the authors failed to demonstrate its effectiveness as a lapse-responsive treatment.

Effects of d-amphetamine and smoking abstinence on cue-induced cigarette craving.

In this study, the authors investigated the effects of the indirect dopamine agonist d-amphetamine (AMPH) on cue-induced cigarette craving in smokers. Abstinent or nonabstinent cigarette smokers (N=21) rated their cravings for cigarettes and for food (control) after pretreatment with AMPH (15 mg) or placebo and before and after viewing blocks of smoking-related, food-related, and neutral pictures. Before the cues were presented, AMPH increased cigarette craving and decreased food craving. Smoking and food cues increased craving for cigarettes and for food, respectively. AMPH also further increased cigarette craving (and decreased food craving) after cue presentation, but it did so regardless of cue type (food or smoking). Smoking abstinence markedly increased craving regardless of cue presentation or drug condition. These results suggest that both AMPH and smoking abstinence can increase cigarette craving, but they do not appear to specifically affect responses to conditioned smoking-related cues.

Stress, depressive symptoms, and smoking cessation among pregnant women.

Perceived stress and depressive symptoms were examined as correlates and predictors of smoking cessation during pregnancy in a sample of 819 pregnant smokers (454 baseline smokers and 365 baseline quitters). Women who quit early in pregnancy had lower levels of stress and depressive symptoms than baseline smokers. Adjusting for level of addiction and other demographic factors related to stress and depressive symptoms eliminated the significant association between depressive symptoms and smoking cessation. Lower levels of stress and depressive symptoms were not predictive of cessation in later pregnancy. Prenatal healthcare providers should continue to assess level of addiction and provide targeted intensive cessation interventions. Interventions that reduce stress and depression may also be of benefit to women who are continuing smokers in early pregnancy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
