心理安全感对冠状动脉介入术前患者焦虑的影响:侵袭性思维与自我损耗的中介作用

Effects of Psychological Safety on Anxiety in Patients Undergoing Percutaneous Coronary Intervention(PCI): Mediating Intrusive Thoughts and Ego Depletion

目的:探讨心理安全感对冠状动脉介入手术(PCI)前患者焦虑的影响以及侵袭性思维与自我损耗的中介作用。方法:采用安全感量表、事件影响量表、自我调节疲劳量表和焦虑自评量表对584名PCI术前患者进行调查。结果:(1)心理安全感与患者焦虑呈显著负相关(r=-0.45,P<0.05);(2)侵袭性思维和自我损耗在心理安全感与患者焦虑之间起中介作用,心理安全感通过三条路径影响患者焦虑:一是侵袭性思维的单独中介作用(β=-0.16,P<0.05);二是自我损耗的单独中介作用(β=-0.08,P<0.05);三是侵袭性思维-自我损耗的链式中介作用(β=-0.03,P<0.05)。结论:心理安全感可负向影响PCI术前患者焦虑,并可通过侵袭性思维和自我损耗间接起作用。

Objective: To explore the effects of psychological safety on anxiety in patients undergoing percutaneous coronary intervention(PCI) and the mediating role of intrusive thoughts and ego depletion. Methods: Totally 584 operation patients were investigated with security questionnaire, impact of event scale, self-regulatory fatigue scale and self-rating anxiety scale. Results:(1)Psychological safety was significantly negatively associated with anxiety(r=-0.45, P<0.05).(2)Patients intrusive thoughts and ego depletion played a mediating role between psychological safety and anxiety. Specifically,psychological safety affected anxiety in three ways: one was the single mediating role of intrusive thoughts(β=-0.16, P<0.05). The second was the single mediating role of ego depletion(β=-0.08, P<0.05), and the third was the chain mediating role of intrusive thoughts and ego depletion(β=-0.03, P<0.05). Conclusion: Patients psychological safety not only negatively affects anxiety, but also can affect anxiety by influencing intrusive thoughts and ego depletion.
