The aim of our study was to determine whether the previously reported findings also apply to a general population in Japan and whether, among current smokers, such personality characteristics can be correlated with the age they started to smoke and their present daily consumption of cigarettes.
Cross-sectional survey.
Miyagi prefecture, in northern Japan.
20,538 residents in Miyagi, aged 40-64 years.
A self-administered questionnaire involving smoking status (current, ex- and non-smokers) and patterns and the Japanese version of the short-form Eysenck Personality Questionnaire-Revised (EPQ-R).
(1) Current and ex-smokers were higher on Extraversion and Psychoticism than non-smokers for both genders. (2) Heavy smokers were higher on Psychoticism than light smokers and those who started to smoke prior to the legally permitted age were higher on Psychoticism than those who did not.
(1) Our study confirmed that the findings which had been previously reported in selected samples in western countries also apply to a general population in Japan; (2) current smokers were found to be heterogeneous in terms of Psychoticism when the age they started to smoke and their present daily consumption of cigarettes were taken into account.
我们研究的目的是确定先前报道的研究结果是否也适用于日本的普通人群，以及在当前吸烟者中，这些人格特征是否与他们开始吸烟的年龄以及目前的每日吸烟量相关。
横断面调查。
日本北部的宫城县。
宫城县20538名年龄在40 - 64岁之间的居民。
一份涉及吸烟状况（当前吸烟者、既往吸烟者和非吸烟者）及模式的自填式问卷，以及艾森克人格问卷简式修订版（EPQ - R）的日语版本。
（1）对于男女两性，当前吸烟者和既往吸烟者在外向性和精神质维度上均高于非吸烟者。（2）重度吸烟者在精神质维度上高于轻度吸烟者，且在法定允许年龄之前开始吸烟的人在精神质维度上高于未在该年龄之前开始吸烟的人。
（1）我们的研究证实，先前在西方国家特定样本中报道的研究结果也适用于日本的普通人群；（2）当考虑到开始吸烟的年龄和目前的每日吸烟量时，发现当前吸烟者在精神质方面存在异质性。
