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.

Objective: Anxiety disorders appear to influence morbidity and medical utilization. However, little is known about the relationship between Generalized Anxiety Disorder, quality of life, and medical utilization, especially among low-income patients. The goals of this investigation were to 1) determine if low-income patients with GAD utilize medical services more than patients with other Axis I diagnoses, or no psychopathology, and 2) compare the health-related quality of life of these three groups. Method: Participants were randomly recruited from public primary care clinics and administered intake assessments of demographics, stress, and health-related self-report questionnaires. At the end of the first year a structured psychiatric interview was administered ( N = 431). Over the second year, patients ( n = 360) were administered a health-related quality of life measure every three months for four assessments. Medical charts were abstracted to collect information about chronic illnesses and visits to outpatient clinics and the emergency department during the two years. Results: Patients were predominantly middle-aged, low-income, uninsured African-American females. In this low-income sample, patients with GAD utilized the emergency department more and reported poorer quality of life than patients with other Axis I disorders and patients without any psychopathology. Conclusion: Low-income patients with GAD utilize the emergency department more and report poorer quality of life than patients with other Axis I disorders and patients without any psychopathology. Programs to identify and treat patients with GAD may yield improvements in quality of life, as well as reduce emergency department utilization.
