According to Beck’s cognitive theory of depression, autonomy (high achievement concerns) and sociotropy (high interpersonal concerns) are vulnerability factors for depression when achievement or interpersonal stressors, respectively, are experienced. This hypothesis was tested among men and women attempting to quit smoking, an achievement stressor that can provoke depressive symptoms. Smokers recruited from the community (N=210) provided information about their quit attempt through mailed questionnaires. For the 48-h period following the quit, relationships among autonomy, sociotropy, coping, depressive symptoms and lapsing were assessed. Structural equation models supported the trait-congruence hypothesis because greater autonomy, but not sociotropy, was associated with elevated depressive symptoms among both men and women smokers. However, results were stronger for men (b=.47, p=.0001) than for women (b=.20, p=.05). After accounting for autonomy’s relationship with depressive symptoms, greater autonomy was inversely associated with lapsing among men (b=.35, p=.01), but not women. Results point to the potential usefulness of a theoretical approach to understanding relationships between depressive symptoms and smoking cessation, and indicate that autonomous personality may be an important factor in smoking cessation in men.

Helping smokers quit is important as smoking is the number one preventable cause of death in the U.S. Smoking activates the mesolimbic dopamine reward system which is also responsible for pleasure associated with other behaviors, including engaging in novel, exciting and/or challenging (i.e., self-expanding) events. We hypothesized that the reward activation achieved by experiencing self-expanding events can supplant the reinforcement normally provided by smoking and can thus facilitate quitting. We investigated this hypothesis among 74 current and 66 former smokers who reported the self-expanding events they experienced for the 2 months prior to their most successful or final, quit attempt, respectively. Former smokers, compared to current smokers, reported significantly more self-expanding events and that the events were more helpful to their quitting. For current smokers, there was a significant moderate-to-large positive correlation between number of self-expanding events and number of days subsequently abstained from smoking. The results support the proposition that experiencing self-expanding activities or events can be beneficial for smoking abstinence.

The majority of smokers who eventually quit do so without formal treatment, but few studies have examined a range of predictors of cessation among self-quitters and whether they differ depending on smokers' gender. The present study examined predictors of quitting in a community sample of 93 men and 117 women smokers attempting to quit on their own. Smokers were mailed a baseline questionnaire battery, and instructed to complete other measures the first and second day of their quit attempt. No gender difference in quit rates was observed, but predictors of smoking differed between men and women. Among men, alcohol use, caffeine consumption, and negative affect predicted smoking on quit day. Among women, nicotine dependence, age, ethnicity, weight control smoking, and not eating during urges predicted smoking on quit day. Social support seeking was negatively associated with smoking on the quit day among women, but the opposite relationship was obtained for men. Men's smoking 4 months later was predicted by baseline social pressures to quit and use of nicotine replacement therapy (NRT). For women, weight control smoking and trait anxiety predicted smoking at the 4-month follow-up.

This study examined interest in genetic testing for lung cancer susceptibility among college students, a group whose smoking rates have increased significantly in the last decade. Sixteen smokers who participated in focus group discussions indicated a generally high level of interest in testing. They also indicated that knowledge of genetic susceptibility would make them feel anxious and motivate them to quit smoking. The study also examined, in a separate sample of undergraduate smokers (n=186), whether these outcomes depend on personality differences in threat sensitivity-responsiveness of the behavioral inhibition system (BIS)--and reward sensitivity--responsiveness of the behavioral activation system (BAS). Smokers completed measures of personality and risk perceptions at baseline and rated risk perceptions, affect, and likelihood of changing smoking behavior in response to 2 hypothetical risk feedback scenarios (high vs. low risk). Smokers higher in reward sensitivity (reward responsiveness) evidenced greater interest in taking genetic tests. If a test indicated elevated risk smokers higher in reward responsiveness would perceive themselves at increased risk and attempt to quit smoking. Threat sensitive smokers would react with greater negative affect. Overall, results indicate that genetic biomarker feedback is a motivator for college student smokers to quit and would be more effective among smokers high in reward sensitivity.
