The research determined the relation of the 2004-2005 American state suicide rates to state means on neuroticism, agreeableness, extraversion, openness, and conscientiousness as assessed by Rentfrow, Gosling, and Potter (2008). Multiple regression strategies were used to analyze relations between state suicide rates and state personality means with state socioeconomic status, White population percent, urban population percent, and depression rates controlled. Multiple regression analysis showed that neuroticism accounted for 32.0% and agreeableness another 16.3% of the variance in suicide rates when demographics and depression were controlled. Lower neuroticism and lower agreeableness were associated with higher suicide rates. Lower neuroticism and lower agreeableness may be important risk factors for completed suicide but not suicidal ideation or attempted suicide.
这项研究确定了 2004 年至 2005 年美国各州的自杀率与 Rentfrow、Gosling 和 Potter（2008 年）评估的各州神经质、宜人性、外向性、开放性和尽责性的关系。采用多元回归策略分析了在控制州社会经济地位、白种人口比例、城市人口比例和抑郁率的情况下，州自杀率与州人格特征之间的关系。多元回归分析表明，在控制人口统计学和抑郁因素后，神经质占自杀率的 32.0%，宜人性占 16.3%。较低的神经质和宜人性与较高的自杀率有关。较低的神经质和宜人性可能是完成自杀的重要风险因素，但不是自杀意念或企图自杀。
