title: Eysenck's personality and tobacco/nicotine dependence in male ever-smokers in Japan.
abstract: To examine the relationship between Eysenck's personality traits and tobacco/nicotine dependence in a male population, a random sample of 200 male ever-smokers aged 35 or older from a community in Japan were interviewed using the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI), which yielded ICD-10, DSM-III-R and DSM-IV diagnoses of tobacco/nicotine dependence. They were also asked to complete the Fagerstrom Tobacco Questionnaire (FTQ) and the short-form Eysenck Personality Questionnaire-Revised. A total of 136 subjects completed both the interview and the questionnaire. Neuroticism scores were significantly higher in those who had lifetime diagnosis of tobacco/nicotine dependence according to ICD-10, DSM-IV, or FTQ criteria than nondependent ever-smokers (p < 0.05). Lie scores were significantly lower in DSM-III-R or DSM-IV tobacco/nicotine dependence than in nondependent ever-smokers (p < 0.05). Multiple logistic regression indicated that neuroticism was significantly associated with a higher risk of ICD-10 tobacco/nicotine dependence (p < 0.05), after controlling for age, education, employment status and smoking behaviors; lie score was significantly associated with a lower risk of DSM-III-R tobacco/nicotine dependence (p < 0.05). It is suggested that neuroticism is associated with a higher risk of tobacco/nicotine dependence in male Japanese ever-smokers. A nonconforming and rebellious attitude or reporting bias represented by higher lie score may be associated with lower rates of tobacco/nicotine dependence.
