Studies examining the relationship between alexithymia and personality exclusively employed self-report measures of alexithymia. In the present study, we examined the relationship of both observer-rated and self-reported alexithymia with the Big Five personality dimensions. We administered the Toronto Structured Interview for Alexithymia (TSIA) as an interview-based measure of alexithymia and, in addition, two self-report questionnaires, the 20-item Toronto Alexithymia Scale (TAS-20) and the Bermond-Vorst Alexithymia Questionnaire (BVAQ). Fifty-one university students were interviewed and completed the alexithymia scales and the NEO Five-Factor Inventory. In contrast to TAS-20 and BVAQ, the Difficulty identifying feelings (DIF) scale of the TSIA was found to be unrelated to neuroticism, suggesting that the frequently reported association between DIF and neuroticism could be due to the use of self-report scales. In contrast, the affective dimension of alexithymia, measured by the BVAQ, was even negatively related with neuroticism. Thus, a paucity of fantasy and little emotional arousal goes together with increased emotional stability. Furthermore, we revealed negative correlations between interview-based alexithymia scores and openness to experience and agreeableness, which cross-validated the self-report findings. Finally, extraversion and conscientiousness each showed only one negative correlation, namely with subscales of the BVAQ. Taken together, our findings show that on the basis of interviews there is no evidence for a relation of DIF with neuroticism, while associations of alexithymia with low openness to experience and low agreeableness emerged irrespective of assessment approach. The relations of alexithymia with personality are discussed in the light of different measurement approaches.

观察者评定的述情障碍及其与人格五因素模型的关系。


研究述情障碍与人格之间关系的研究专门采用了述情障碍的自我报告测量方法。在本研究中，我们研究了观察者评价和自我报告的述情障碍与大五人格维度的关系。我们进行了多伦多述情障碍结构化访谈 (TSIA)，作为基于访谈的述情障碍测量方法，此外，我们还实施了两份自我报告问卷：20 项多伦多述情障碍量表 (TAS-20) 和 Bermond-Vorst 述情障碍问卷（ BVAQ）。 51 名大学生接受了采访，并完成了述情障碍量表和 NEO 五因素量表。与 TAS-20 和 BVAQ 相比，TSIA 的情感识别难度 (DIF) 量表被发现与神经质无关，这表明经常报道的 DIF 与神经质之间的关联可能是由于使用了自我报告量表。相比之下，通过 BVAQ 测量的述情障碍的情感维度甚至与神经质呈负相关。因此，缺乏幻想和很少的情绪唤起与情绪稳定性的增强相伴。此外，我们发现基于访谈的述情障碍分数与对经验的开放性和宜人性之间存在负相关性，这交叉验证了自我报告的发现。最后，外向性和尽责性仅表现出一种负相关，即与 BVAQ 的分量表负相关。总而言之，我们的研究结果表明，根据访谈，没有证据表明 DIF 与神经质之间存在关系，而无论评估方法如何，述情障碍与对经验的开放性和宜人性低之间的关联都会出现。 根据不同的测量方法讨论述情障碍与人格的关系。
