This study investigated both whether alexithymia is a predictor for mental health and adjustment disorder, and its pathway relationships. Total of 158 young male conscripts diagnosed with adjustment disorder and another 155 young normal male controls were enrolled. Structural equation modeling showed, parental bonding influence personality, then affects alexithymic traits, and then affects mental health, finally further develop adjustment disorder. Receiver operating characteristic (ROC) found the optimal cutoff point for screening of adjustment disorder using DIF of the TAS-20 was 21/22, resulting in a sensitivity of 0.84, specificity of 0.87, PPV of 0.87, and NPV of 0.84. The DIF of alexithymia can be used as a screening index for adjustment disorder. With the high degree of association between alexithymia and other psychiatric disorders, especially in those relatively lacking in the ability to empathize, future studies should investigate whether DIF can be generalizable to the screening of other empathy-related and psychiatric disorders.
本研究旨在探讨述情障碍是否是心理健康和适应障碍的预测因素，以及述情障碍的作用途径。共纳入 158 名被诊断为适应障碍的年轻男性新兵和 155 名年轻正常男性对照。结构方程模型显示，父母养育方式影响个性，进而影响述情障碍特征，进而影响心理健康，最终进一步发展为适应障碍。受试者工作特征（ROC）分析发现，使用 TAS-20 的 DIF 筛选适应障碍的最佳截断点为 21/22，其灵敏度为 0.84，特异性为 0.87，阳性预测值为 0.87，阴性预测值为 0.84。述情障碍的 DIF 可作为适应障碍的筛查指标。鉴于述情障碍与其他精神障碍之间的高度关联，尤其是在那些共情能力相对较弱的人群中，未来的研究应探讨 DIF 是否可以推广到其他与共情相关的精神障碍的筛查中。
