One of the most consistent models investigating the relationship between premorbid personality and depression was described by Tellenbach. According to this model, concern with orderliness, conscientiousness, hyper/hetereonomia and intolerance of ambiguity are the core features of Typus Melancholicus (TM). Previous studies showed a relationship between unipolar depression and TM. The primary hypothesis of this study was that patients affected by unipolar depressive disorders bare more of TM-related features of concern with orderliness and conscientiousness than healthy subjects.
In this single center cross-sectional study we recruited 74 patients affected by unipolar depressive disorders according to DSM-5 criteria and 60 healthy controls. In order to assess the presence of TM's orderliness and conscientiousness we adopted the factors of Kasahara's Inventory for the Melancholic Type Personality (KIMTP) named "harmony in personal relationships" and "social norms". Stress-Related Vulnerability Scale (SVS) was administered to explore the relationship between measures of TM and perceived stress.
Independent sample t test disclosed significantly higher scores on KIMTP "harmony in personal relationships" (orderliness) but not on "social norms" (conscientiousness) in the clinical sample (p<0.001) compared to the non-clinical sample. Pearson's correlation disclosed a significant positive correlation between stress scores and KIMTP'S "harmony in personal relationships" subscale.
KIMTP's "harmony in personal relationships" (orderliness) was higher in patients with unipolar depression than in non-clinical subjects, and positively associated with perceived stress, while KIMTP's "social norms" (conscientiousness) was (i) similarly represented across the two groups, and (ii) not correlated with perceived stress. This raises the possibility that, among the core features of TM, concern with orderliness can be considered as a relevant and potentially premorbid personality factor in relation to unipolar depressive disorders.
探索人格与抑郁关系的最一致模型之一是由 Tellenbach 描述的。根据该模型，有序性、责任心、高/低自主性和对模糊性的不容忍是忧郁症人格类型（TM）的核心特征。先前的研究表明，单相抑郁症与 TM 之间存在关联。本研究的主要假设是，受单相抑郁障碍影响的患者比健康受试者更具有 TM 相关的有序性和责任心特征。
在这项单中心横断面研究中，我们招募了 74 名符合 DSM-5 标准的单相抑郁障碍患者和 60 名健康对照者。为了评估 TM 的有序性和责任心的存在，我们采用了 Kasahara 的忧郁型人格量表（KIMTP）的因子，分别命名为“人际关系和谐”和“社会规范”。我们还进行了压力相关易感性量表（SVS），以探索 TM 测量值与感知压力之间的关系。
独立样本 t 检验显示，在临床组中，KIMTP 的“人际关系和谐”（有序性）得分显著高于非临床组（p<0.001），但在“社会规范”（责任心）方面无显著差异。Pearson 相关分析显示，压力评分与 KIMTP 的“人际关系和谐”子量表之间存在显著正相关。
与非临床受试者相比，单相抑郁障碍患者的 KIMTP 的“人际关系和谐”（有序性）得分更高，且与感知压力呈正相关，而 KIMTP 的“社会规范”（责任心）在两组之间表现相似，且与感知压力无关。这提示我们，在 TM 的核心特征中，有序性可能被视为与单相抑郁障碍相关的一个重要且潜在的前驱人格因素。
