Personality disorder functioning styles might contribute to the inconclusive findings about alexithymic features in schizophrenia. We therefore studied the relationship between alexithymia and personality styles in paranoid schizophrenia.
We administered the Chinese versions of the Toronto Alexithymia Scale (TAS-20), the Parker Personality Measure (PERM), the Positive and Negative Syndrome Scale as well as the Hamilton Anxiety and Depression Scales to 60 paranoid schizophrenia patients and 60 healthy control subjects.
Patients scored significantly higher on the Positive and Negative Syndrome Scale, TAS 'difficulty identifying feelings' and 'difficulty describing feelings', Hamilton Depression Scale and most PERM scales. In healthy subjects, difficulty identifying feelings predicted the PERM 'dependent' style, and the Hamilton Anxiety Scale predicted difficulty identifying feelings and difficulty describing feelings. In patients, difficulty identifying feelings nonspecifically predicted all the PERM scales; by contrast, the PERM 'antisocial' style predicted difficulty identifying feelings, the 'avoidant' style predicted difficulty describing feelings, and the 'histrionic' and 'paranoid (-)' styles predicted 'externally oriented thinking'.
Personality disorder functioning styles - instead of anxiety, depression, psychotic symptoms or disease duration - were specifically associated with alexithymia scales in our patients, which sheds light on a cognitive-personological substrate in paranoid schizophrenia on the one hand, and calls for a longitudinal design to discover how premorbid or postacute residual personality styles contribute to the sluggish disorder on the other.
人格障碍功能风格可能导致精神分裂症患者存在述情障碍特征的不确定发现。因此，我们研究了偏执型精神分裂症患者中述情障碍与人格风格之间的关系。
我们对 60 名偏执型精神分裂症患者和 60 名健康对照者进行了多伦多述情障碍量表（TAS-20）、帕克人格量表（PERM）、阳性和阴性症状量表以及汉密尔顿焦虑和抑郁量表的中文版测试。
患者在阳性和阴性症状量表、TAS 的“难以识别情感”和“难以描述情感”、汉密尔顿抑郁量表和大多数 PERM 量表上的得分显著更高。在健康受试者中，难以识别情感预测了 PERM 的“依赖”风格，而汉密尔顿焦虑量表预测了难以识别情感和难以描述情感。在患者中，难以识别情感非特异性地预测了所有的 PERM 量表；相比之下，PERM 的“反社会”风格预测了难以识别情感，“回避”风格预测了难以描述情感，而“表现型”和“偏执型（-）”风格预测了“外向思维”。
人格障碍功能风格——而不是焦虑、抑郁、精神病症状或疾病持续时间——与我们患者的述情障碍量表具体相关，这一方面揭示了偏执型精神分裂症的认知人格基础，另一方面需要进行纵向设计以发现如何在前驱或急性后残留人格风格对迟钝的障碍产生影响。
