This study examined the relationship between the emotion-regulating factor alexithymia and the occurrence of posttraumatic stress disorder (PTSD) after critical incidents in a nonclinical sample of 136 nurses and ambulance personnel working in military facilities. The results showed that alexythima accounts for variance in PTSD symptoms. Breaking PTSD into its 4 symptom clusters, alexithymia was found to predict numbing and hyperarousal symptoms but not avoidance or reexperiencing symptoms. Finally, the rarely investigated, but clinically relevant, distinctive subdimensions of alexithymia were examined in relation to the 4 PTSD clusters. The difficulty identifying feelings subscale contributed most to the numbing and hyperarousal PTSD subscales. Clinical implications and future research directions are discussed.
本研究考察了情感调节因素述情障碍与非临床样本中 136 名在军事设施工作的护士和救护人员在经历重大事件后发生创伤后应激障碍（PTSD）之间的关系。结果表明，述情障碍可以预测 PTSD 症状的变异。将 PTSD 分为 4 个症状群，发现述情障碍可以预测麻木和过度警觉症状，但不能预测回避或再体验症状。最后，研究了述情障碍的很少被研究但具有临床意义的独特亚维度与 PTSD 的 4 个亚群的关系。难以识别情绪的分量表对麻木和过度警觉的 PTSD 分量表的贡献最大。讨论了临床意义和未来的研究方向。
