There has been limited research investigating personality traits as predictors of manic and depressive symptoms in bipolar individuals. The present study investigated the relation between personality traits and the course of bipolar disorder. The purpose of this study was to identify specific personality traits that predict the course of manic and depressive symptoms experienced by bipolar individuals.
The sample consisted of 39 participants with bipolar I disorder assessed by the Structured Clinical Interview for DSM-IV. Personality was assessed using the NEO Five-Factor Inventory. The Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Rating Scale were used to assess symptom severity on a monthly basis.
Consistent with previous research on unipolar depression, high Neuroticism predicted increases in depressive symptoms across time while controlling for baseline symptoms. Additionally, high Conscientiousness, particularly the Achievement Striving facet, predicted increases in manic symptoms across time.
The current study was limited by the small number of participants, the reliance on a shortened version of a self-report personality measure, and the potential state-dependency of the personality measures.
Specific personality traits may assist in predicting bipolar symptoms across time. Further studies are needed to tease apart the state-dependency of personality.
关于人格特质作为双相情感障碍患者躁狂和抑郁症状预测因素的研究有限。本研究调查了人格特质与双相情感障碍病程之间的关系。本研究的目的是确定能够预测双相情感障碍患者经历的躁狂和抑郁症状病程的特定人格特质。
样本包括39名通过《精神疾病诊断与统计手册》第四版（DSM-IV）结构化临床访谈评估的双相I型障碍患者。使用NEO五因素问卷评估人格。每月使用改良汉密尔顿抑郁量表和贝克-拉法尔森躁狂量表评估症状严重程度。
与先前关于单相抑郁的研究一致，在控制基线症状的情况下，高神经质预测了抑郁症状随时间的增加。此外，高尽责性，尤其是成就追求方面，预测了躁狂症状随时间的增加。
本研究受到参与者数量少、依赖自我报告人格测量的简版以及人格测量潜在的状态依赖性的限制。
特定的人格特质可能有助于预测双相情感障碍症状随时间的变化。需要进一步的研究来厘清人格的状态依赖性。
