摘要： 目的·探讨应激感受、人格特质与惊恐障碍（panic disorder, PD）症状的关系，并检验应激感受在不同的人格特质中与PD症状间的中介作用。方法·选取符合《精神障碍诊断及统计手册（第五版）》［Diagnostic and Statistical Manual of Mental Disorders（Fifth Edition），DSM-5］诊断标准的PD患者55例，采用大五人格量表（NEO Five-Factor Inventory，NEO-FFI）测量患者的人格特质，用惊恐障碍严重度量表（Panic Disorder Severity Scale，PDSS）测量患者的PD症状严重程度，用应激感受量表（Perceived Stress Scale，PSS）测量患者的应激感受水平。结果·NEO-FFI中神经质、宜人性分量表得分以及PSS得分与PDSS总分均显著相关，相关系数分别为r0.379（P0.004）、r-0.420（P0.001）、r0.330（P0.014）；中介效应分析发现，应激感受完全中介了宜人性对PD症状的影响，中介效应为32.43%。结论·人格特质中神经质可能与PD症状呈正相关，宜人性可能与PD症状呈负相关，应激感受在宜人性与PD症状之间发挥了完全中介作用。

Abstract:
Objective · To explore the relationship among perceived stress, personality traits and panic disorder (PD) symptoms, and to test the mediating effect of perceived stress on PD symptoms in different personality traits. Methods · A total of 55 PD patients were selected according to Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5). The NEO Five-Factor Inventory (NEO-FFI) was used to measure the personality traits. The Panic Disorder Severity Scale (PDSS) was used to measure the PD symptoms severity. The Perceived Stress Scale (PSS) was used to measure the level of the perceived stress. Results · Both the neuroticism, agreeableness subscale scores of NEO-FFI and scores of PSS were significantly correlated with the total scores of PDSS, and the correlation coefficient were r0.379 (P0.004), r-0.420 (P0.001) and r0.330 (P0.014), respectively. The mediating effect analysis showed that perceived stress completely mediated the effect of agreeableness on PD symptoms, and the mediating effect was 32.43%. Conclusion · In personality traits, neuroticism may be positively correlated with PD symptoms, while agreeableness may be negatively correlated with PD symptoms. The perceived stress may play a completely mediating role between agreeableness and PD symptoms.
Key words: panic disorder (PD), personality trait, perceived stress, mediating effect
