述情障碍与焦虑、抑郁的关系:无聊倾向性的中介作用

The Relationship between Alexithymia and Emotional Symptoms: Mediating Effects of Boredom Proneness

目的:探讨述情障碍、无聊倾向性与焦虑、抑郁之间的关系。方法:采用多伦多述情障碍量表中文版(TAS-20)、大学生无聊倾向问卷(BPS)、症状自评量表(SCL-90)中的焦虑、抑郁分量表对369名大学生进行问卷调查。结果:(1)述情障碍总分、无聊倾向性总分与焦虑、抑郁存在显著正相关,无聊倾向性总分与述情障碍及各因子同时存在显著正性相关;(2)结构方程模型分析显示:述情障碍对无聊倾向性的外部刺激维度有显著影响(β=0.46);无聊倾向性的外部刺激维度对焦虑、抑郁存在直接作用(β=0.21),无聊倾向性的外部刺激维度在述情障碍与焦虑、抑郁之间起部分中介效应(解释总效应的14.6%)。结论:述情障碍既直接影响焦虑、抑郁,同时又通过无聊倾向性对其产生间接影响,无聊倾向性在述情障碍与焦虑、抑郁关系中起部分中介作用。

Objective： To explore the association of anxiety and depression with alexithymia and boredom proneness in college students. Methods： A total of 369 college students were assessed by Boredom Proneness Scale（BPS）, twenty-item Toronto Alexithymia Seale（TAS-20）and the depression and anxiety subseales of Symptom Checklist-90. Results： （1）Anxiety and depression were significant positive correlated with the total score of alexithymia and boredom proneness. The total score of boredom proneness was significantly associated with alexithymia and its factors; （2）Structural equation nlodel analysis showed that alexithymia contributes an positive influence, which is significant to external stimulation of the boredom proneness（β=0.46）, and external stimulation contributes an positive influence, which is significant to anxiety and depression （β=0.21）, and an mediating effect made by external stimulation counted 14.6% of the total effect. Conclusion： Alexithymia can directly affect anxiety and depression, and also indirectly influence it through boredom proneness.
