The effects of depressed mood on smoking cessation: Mediation by postcessation self-efficacy.

This study evaluated the relationship between precessation depressed mood and smoking abstinence and assessed the mediation of this effect by postcessation self-efficacy, urges to smoke, nicotine withdrawal, and coping behavior. The sample included 121 smokers previously treated in a randomized controlled trial involving behavior therapy and the nicotine patch. The results showed that precessation depressed mood was inversely related to 6-month abstinence. This effect remained significant after controlling for treatment, possible depression history, baseline smoking rates, and several other demographic factors. Postcessation self-efficacy, at the 2-, 4-, and 8-week postquit assessments, was the strongest mediator of the effects of precessation depressed mood on abstinence, accounting for 32%, 38%, and 48% of the effect of mood on abstinence, respectively.

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)     

Implicit and explicit attitudes predict smoking cessation: Moderating effects of experienced failure to control smoking and plans to quit.

The current study tested implicit and explicit attitudes as prospective predictors of smoking cessation in a Midwestern community sample of smokers. Results showed that the effects of attitudes significantly varied with levels of experienced failure to control smoking and plans to quit. Explicit attitudes significantly predicted later cessation among those with low (but not high or average) levels of experienced failure to control smoking. Conversely, however, implicit attitudes significantly predicted later cessation among those with high levels of experienced failure to control smoking, but only if they had a plan to quit. Because smoking cessation involves both controlled and automatic processes, interventions may need to consider attitude change interventions that focus on both implicit and explicit attitudes.

Acute impact of the September 11 tragedy on smoking and early relapse rates among smokers attempting to quit.

The September 11, 2001, terrorist attacks on the United States had widespread behavioral and emotional impacts. At the time of the terrorist attacks, 462 smokers from the Washington, DC, area had been entered into a study comparing scheduled versus ad lib dosing regimens for nicotine inhalers. Mean smoking rates the week following September 11 were only slightly higher than mean smoking rates the week prior to September 11. Increases in smoking rates following the terrorist attacks, however, were significantly associated with scores on the Impact of Events Scale-Revised (Pearson's r = .25, p = .01). Although the terrorist attacks were associated with acute increases in smoking and early relapse rates, the effect was relatively small and modestly associated with retrospective reports of the event's emotional impact.

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.
