正负性情绪在肺癌患者创伤后应激障碍与睡眠质量之间的中介效应分析

Analysis on Intermediary Effect of Positive and Negative Emotions between Post-traumatic Stress Disorder and Sleep Quality in Lung Cancer Patients

目的:探讨肺癌患者创伤后应激障碍与睡眠质量的现状及正负性情绪在其之间的中介效应。方法:2020年3月1日~2021年4月30日,采用便利抽样法选取3所三级甲等医院的住院肺癌患者作为研究对象,采用匹兹堡睡眠质量指数量表、正性负性情绪量表和创伤后应激障碍自评量表,对纳入研究的549例肺癌患者进行横断面调查。结果:肺癌患者睡眠质量指数总分为(10.34±4.93)分,正性情绪总分为(16.18±4.89)分,负性情绪总分为(19.19±4.71)分,创伤后应激障碍总分为(48.24±12.84)分。肺癌患者睡眠质量指数总分与正性情绪呈负相关(P<0.05),与负性情绪呈正相关(P<0.05),与创伤后应激障碍呈正相关(P<0.05)。路径分析表明,创伤后应激障碍可直接正向预测睡眠质量,也可通过正负性情绪的中介效应作用于睡眠质量,其中介作用分别占总效应的16.61%、36.46%。结论:我国肺癌患者睡眠质量普遍较差,创伤后应激障碍症状突出,临床工作者应给予患者针对性心理干预,降低患者创伤后应激程度,鼓励患者维持积极正性情绪,缓解负性情绪,以改善睡眠质量,促进患者康复。

Objective:To explore the post-traumatic stress disorder and sleep quality status in the lung cancer patients and the intermediary effect between the positive and negative emotions.Methods:The convenience sampling method was used to select in-patients with lung cancer in 3 first-class ternary hospitals during March 1,2020 to April 30,2021 as the research objects,the Pittsburgh sleep quality index scale,positive negative emotions scale and post-traumatic stress disorder self-evaluation scale were used to conduct a cross-sectional survey among 549 patients with lung cancer included in the study.Results:The total scores of sleep quality index in the lung cancer patients were(10.34±4.93)points,positive emotion total scores were(16.18±4.89)points,negative emotion total scores were(19.19±4.71)points,post-traumatic stress disorder total score were(48.24±12.84)points.The sleep quality index total scores in lung cancer patients were negatively correlated with positive emotions,positively correlated with negative emotions,and positively correlated with post-traumatic stress disorder(P<0.05).Path analysis showed that post-traumatic stress disorder can positively predict directly sleep quality,can also affect sleep quality through the positive and negative emotional mediation,and the intermediary role respectively accounted for 16.61%and 36.46%of total effect.Conclusion:The lung cancer patients′sleep quality is generally poor,with post-traumatic stress disorder symptoms,targeted psychological intervention should be given to patients by the clinical staff,so as to reduce their post-traumatic stress symptoms,encourage patients to maintain positive emotions,reduce negative emotions,in order to improve their sleep quality,and promote their physical and mental rehabilitation.
