癌症患者述情障碍与负性情绪的关系：侵袭性思维的中介作用

目的：探讨癌症患者述情障碍与负性情绪之间的关系，并检验侵袭性思维在述情障碍与负性情绪之间的 作用。方法：采用多伦多述情障碍量表中文版、事件影响量表修订版、流行病调查中心用抑郁问卷、状态-特质焦虑 量表中的状态-焦虑分量表对115名癌症患者进行问卷调查。结果：负性情绪与侵袭性思维及述情障碍各维度存在显 著正相关(r：0.251~0.600，P<0.01)，述情障碍总分及其辨别情感困难、描述情感困难因子分值与侵袭性思维呈低至中 度正相关(r：0.261~0.430，P<0.01)。述情障碍对负性情绪不仅具有直接效应，还可通过侵袭性思维间接作用于负性情 绪，侵袭性思维的中介效应占总效应的40.71%。结论：侵袭性思维在述情障碍与负性情绪关系中起部分中介作用。

Alexithymia and negative emotions in cancer patients: Mediating effects of intrusive thoughts

Objective: To explore associations of negative emotions with alexithymia and intrusive thoughts in cancer patients. Methods: A total of 115 cancer patients were assessed by Impact of Event Scale-Revised, the 20- item Toronto Alexithymia Scale, the Center for Epidemiological Studies Depression Scale, and the state anxiety subscales of State-Trait Anxiety Inventory. Results: Negative emotions were positively correlated with alexithymia and the intrusive thoughts (r 0.251 to 0.600, P<0.01). Intrusive thoughts were significantly associated with the total score of alexithymia, difficulty in identifying feelings, and difficulty in describing feelings (r 0.261 to 0.430, P<0.01). Th e relation between alexithymia and negative emotions was partially mediated by intrusive thoughts, accounting for 40.71% of the alexithymia in total negative emotions. Conclusion: Intrusive thoughts play a role, at least partially in mediation of alexithymia and negative emotions.
