Previous research on alexithymia has led to controversy over its prevalence in panic disorder. The aim of this study was to assess the difference in the prevalence of alexithymia in panic disorder and other anxiety disorders.
We performed a cross-sectional study on a sample of 71 patients diagnosed with panic disorder and 113 patients diagnosed with other anxiety disorders; both groups were 18-50 years old. Primary outcome was the 20-item Toronto Alexithymia Scale (TAS) score. Secondary outcome was the prevalence of alexithymia defined as a TAS score ≥61.
Patients diagnosed with panic disorder had a 25% higher score on the TAS subscale of difficulty identifying feelings than patients diagnosed with other anxiety disorders. The prevalence of alexithymia was 27% in patients with panic disorder and 13% in patients with other anxiety disorders. Patients diagnosed with panic disorder had significantly higher odds for alexithymia.
The results of our study support the hypothesis of higher prevalence of alexithymia in individuals with panic disorder than in individuals with other anxiety disorders. In addition, difficulty identifying feelings as a salient feature of alexithymia is higher in panic disorder than in other anxiety disorders.
先前关于述情障碍的研究引发了对其在惊恐障碍中患病率的争议。本研究的目的是评估惊恐障碍和其他焦虑障碍中述情障碍患病率的差异。
我们对71名被诊断为惊恐障碍的患者和113名被诊断为其他焦虑障碍的患者进行了横断面研究；两组患者年龄均在18至50岁之间。主要结局是20项多伦多述情障碍量表（TAS）得分。次要结局是述情障碍的患病率，定义为TAS得分≥61。
被诊断为惊恐障碍的患者在难以识别情感的TAS子量表上的得分比被诊断为其他焦虑障碍的患者高25%。惊恐障碍患者中述情障碍的患病率为27%，其他焦虑障碍患者中为13%。被诊断为惊恐障碍的患者患述情障碍的几率显著更高。
我们的研究结果支持这样的假设，即惊恐障碍患者中述情障碍的患病率高于其他焦虑障碍患者。此外，难以识别情感作为述情障碍的一个显著特征，在惊恐障碍中比在其他焦虑障碍中更为突出。
