The interactive effect of personal factors and social factors upon suicide risk is unclear. We conducted prospective cohort study to investigate whether the impact of the economic crisis in 1997-1998 upon suicide risk differed according to Neuroticism and Psychoticism personality traits.
The Miyagi Cohort Study in Japan with a follow-up for 19 years from 1990 to 2008 has 29,432 subjects aged 40-64 years at baseline who completed a questionnaire about various health habits and the Japanese version of the Eysenck Personality Questionnaire - Revised Short Form in 1990.
The suicide mortality rate increased from 4.6 per 100,000 person-years before 1998 to 27.8 after 1998. Although both Neuroticism and Psychoticism were significantly associated with an increased risk of mortality during the whole period from 1990 to 2008, the impact of the economic crisis upon suicide risk differed between the Neuroticism and Psychoticism personality traits. Compared with the lowest category, the hazard ratios (HRs) for the highest Neuroticism increased from 0.66 before 1998 to 2.45 after 1998. On the other hand, the HRs for the highest Psychoticism decreased from 7.85 before 1998 to 2.05 after 1998.
The impact of the 1997-1998 economic crisis upon suicide risk differed according to personality. Suicide risk increased among these with higher Neuroticism after the economic crisis, but this was not the case for other personality subscales.
个人因素和社会因素对自杀风险的交互作用尚不清楚。我们进行了一项前瞻性队列研究，以调查1997 - 1998年经济危机对自杀风险的影响是否因神经质和精神质人格特质而异。
日本宫城队列研究从1990年到2008年进行了19年的随访，基线时有29432名年龄在40 - 64岁的受试者，他们在1990年完成了一份关于各种健康习惯的问卷以及艾森克人格问卷修订版简式的日文版。
自杀死亡率从1998年前的每10万人年4.6例增加到1998年后的27.8例。虽然在1990年至2008年的整个期间，神经质和精神质都与死亡率增加显著相关，但经济危机对自杀风险的影响在神经质和精神质人格特质之间有所不同。与最低类别相比，最高神经质类别的风险比（HRs）从1998年前的0.66增加到1998年后的2.45。另一方面，最高精神质类别的HRs从1998年前的7.85下降到1998年后的2.05。
1997 - 1998年经济危机对自杀风险的影响因人格而异。经济危机后，神经质较高的人群自杀风险增加，但其他人格量表则不然。
