The purpose of the current investigation was to examine the personality predictors of bipolar disorder symptoms, conceptualized as one-dimensional (bipolarity) or two-dimensional (mania and depression). A psychiatric sample (N=370; 45% women; mean age 39.50 years) completed the Revised NEO Personality Inventory and the Minnesota Multiphasic Personality Inventory -2. A model in which bipolar symptoms were represented as a single dimension provided a good fit to the data. This dimension was predicted by Neuroticism and (negative) Agreeableness. A model in which bipolar symptoms were represented as two separate dimensions of mania and depression also provided a good fit to the data. Depression was associated with Neuroticism and (negative) Extraversion, whereas mania was associated with Neuroticism, Extraversion and (negative) Agreeableness. Symptoms of bipolar disorder can be usefully understood in terms of two dimensions of mania and depression, which have distinct personality correlates.
当前调查的目的是检验双相情感障碍症状的人格预测因素，这些症状被概念化为一维（双极性）或二维（躁狂和抑郁）。一个精神病学样本（N = 370；45%为女性；平均年龄39.50岁）完成了修订版的大五人格量表（NEO-PI-R）和明尼苏达多相人格调查表-2（MMPI-2）。一个将双相情感障碍症状表示为单一维度的模型与数据拟合良好。这个维度由神经质和（消极的）宜人性预测。一个将双相情感障碍症状表示为躁狂和抑郁两个独立维度的模型也与数据拟合良好。抑郁与神经质和（消极的）外向性相关，而躁狂与神经质、外向性和（消极的）宜人性相关。双相情感障碍的症状可以根据躁狂和抑郁这两个维度来有效理解，这两个维度具有不同的人格相关性。
