The role of psychological detachment in the care burden and fatigue of the primary caregivers of patients with cancer

目的探讨癌症患者主要照顾者心理脱离在照顾负担与疲劳间的中介作用,为缓解其疲劳提供依据。方法采用便利抽样法选取2017年12月~2018年4月在中国科学技术大学附属第一医院肿瘤科就诊的242例癌症患者主要照顾者为研究对象。采用一般资料调查问卷、心理脱离量表(PD)、Zarit照顾者负担量表(ZBI)、疲劳量表(FS-14)进行调查,运用多元回归中介效应分析及Bootstrap法进行验证。结果照顾者疲劳得分为(6.40±3.61)分。相关分析显示,照顾负担与心理脱离呈负相关(r=-0.59,P <0.01);照顾负担与疲劳呈正相关(r=0.51,P <0.01);心理脱离与疲劳呈负相关(r=-0.81,P <0.01)。中介效应分析,心理脱离在照顾负担与疲劳之间起完全中介作用,效应值为82.71%。结论心理脱离是癌症患者主要照顾者照顾负担与疲劳的中介变量。
