背景：据称，抑郁症扭曲了一般人格特质的评估。为了验证这一假设，我们检查了评分的修订NEO人格量表（NEO-PI-R）给予急性抑郁症患者在基线和14至26周后的治疗与抗抑郁medication.Method：250例患者完成了NEO-PI-R在基线，109例患者后14至26周的抗抑郁药物治疗。48例患者（49.5%）被确定为应答者，49例（50.5%）被确定为无应答者。其余12例患者被排除在外，因为他们符合HRSD反应标准，但不是在治疗completion.Results的SCID-I MDD标准：在基线，NEO-PI-R量表表现出很高的内部一致性和复制的规范性因素结构，这表明心理测量特性被保留。在无应答者中，重测相关性一致较高（rs= 0.50至0.88），平均水平变化不大，这为急性抑郁发作期间人格自我报告的一致性提供了证据。NEO-PI-R量表在同时预测一些临床标准中显示出结构效度。有效的治疗不良显着影响的平均水平的神经质，减少，外向性，开放性，和judiciousness，increased.Limitations：参与者是从临床数据库，并没有随机分配的treatment.Conclusions：结果表明，急性抑郁症的影响是放大有点人格特征的人容易患抑郁症。而不是把这些抑郁症引起的人格特质水平评估的变化作为一种扭曲，我们把它们解释为个人当前状况的准确反映。人格特质具有生物学基础，当它们被改变时（通过疾病或治疗干预），特质水平也会改变。(c)2005 Elsevier B.

Background: It is alleged that depression distorts the assessment of general personality traits. To test that hypothesis, we examined scores on the Revised NEO Personality Inventory (NEO-PI-R) administered to acutely depressed patients at baseline and 14 to 26 weeks after treatment with antidepressant medication.Method: Two hundred and fifty patients completed the NEO-PI-R at baseline, 109 patients after 14 to 26 weeks of antidepressant pharmacotherapy. 48 patients (49.5%) were identified as responders while 49 (50.5%) were identified as nonresponders. The remaining 12 patients were excluded because they met HRSD response criteria but not the SCID-I MDD criteria at treatment completion.Results: At baseline, NEO-PI-R scales showed high internal consistency and replicated the normative factor structure, suggesting that psychometric properties were preserved. Among non-responders, retest correlations were uniformly high (rs=.50 to .88) and mean levels showed little change, providing evidence for the consistency of personality self-reports during an acute depressive episode. NEO-PI-R scales showed construct validity in the concurrent prediction of a number of clinical criteria. Effective treatment bad significant effects on the mean levels of neuroticism, which decreased, and extraversion, openness, and conscientiousness, which increased.Limitations: The participants were from a clinical database and were not randomly assigned for the treatment.Conclusions: The results suggest that the effect of acute depression is to amplify somewhat the personality profile of people prone to depression. Rather than regard these depression-caused changes in assessed personality trait levels as a distortion, we interpret them as accurate reflections of the current condition of the individual. Personality traits have biological bases, and when they are changed (by disease or therapeutic interventions) trait levels change. (c) 2005 Elsevier B.V. All rights reserved.
