Objective: The five-factor model of personality was used to describe the correlates of smoking abstinence. Methods: Following treatment in the Mayo Clinic Nicotine Dependence Center, the six month abstinence status was determined by self-report. Sixteen months to 2.4 years following the initial treatment evaluation, and 10 months to 1.9 years after the abstinence status was determined, 475 patients were mailed a Neuroticism, Extraversion, Openness, Five-Factor Inventory questionnaire. Ninety-nine abstinent and 151 smoking patients returned a completed questionnaire. Results: Multivariate analysis showed that low scores on neuroticism and openness were associated with tobacco abstinence. In addition, high scores on neuroticism and low scores on agreeableness and conscientiousness were associated with predictors of poor outcome including greater number of cigarettes smoked per day, initiation of smoking prior to age 18, and a Fagerström Test for Nicotine Dependence score of ≥ 6. Conclusions: Personality characteristics as predictors of smoking abstinence following treatment warrant further investigation in prospective clinical trails. Treatment matching using personality profiling as a guide may be a valuable tool for improving abstinence rates following treatment for nicotine dependence.

PURPOSE: There is a current lack of consensus about the effectiveness of nicotine dependence treatment for cancer patients. This retrospective study examined the 6-month tobacco abstinence rate among lung cancer patients treated clinically for nicotine dependence. PATIENTS AND METHODS: A date-of-treatment matched case control design was used to compare lung cancer patients (201 lung cancer patients, 41% female) and nonlung cancer patients (201 controls, 45% female) treated in the Mayo Clinic Nicotine Dependence Center between 1988 and 2000. The intervention involves a brief consultation with a nicotine dependence counselor. A treatment plan individualized to the patient’s needs is then developed. The primary end point was the self-reported, 7-day point prevalence abstinence from tobacco at 6-month follow-up. RESULTS: At baseline, compared with the controls, the lung cancer patients were significantly older (P < .001), reported higher motivation to stop smoking (P = .003), and were at a higher stage of change (P = .002). The 6-month tobacco abstinence rate was 22% for the lung cancer patients compared with 14% of the control patients (P = .024). After adjusting for age, sex, baseline cigarettes smoked per day, and stage of change, no significant difference was detected between lung cancer patients and controls on the tobacco abstinence rate. CONCLUSION: The results suggest that nicotine dependence treatment is effective for patients with a diagnosis of lung cancer. The majority of lung cancer patients were motivated to stop smoking.
