结构方程模型在癌症患者家属生活质量评价中的应用

Application of structural equation modeling in evaluating quality of life among relatives of cancer patients

目的:评价癌症患者家属的护理负担和生活质量,并对其影响因素进行研究。方法:采用中文版Zarit护理负担量表、癌症患者家属生活质量调查表和患者日常生活能力量表进行问卷调查。结果:结构方程模型拟合参数GFI=0.936,AGFI=0.860,CFI=0.959,模型拟合较好。护理负担显著影响护理者生活质量(P<0.01),患者日常生活能力和护理者特征可通过影响护理负担,对护理者生活质量产生间接影响。结论:未来的干预措施应围绕改善患者日常生活能力和加强协助照顾来帮助护理者减轻负担,最终达到提高护理者生活质量的目的。

Objective： To evaluate the quality of life and caregiver burden among relatives of cancer patients, and analyze the influence factors. Methods ： Chinese version of Zarit Caregiver Burden Interview, Quality of Life Family Version and Activity of Daily Living Scale were used to complete the survey. Results：The parameters of structural equation modeling were GFI = 0. 875, AGFI = 0. 833, CFI = 0. 888 which represented a better model fit. Caregiver burden had a significant effect on caregiver＇s quality of life（ P 〈0.01 ） ,and patient＇s activity of daily living and earegiver characteristics had indirect effects on it through affecting caregiver burden directly. Conclusion：How to improve patient＇s activity of daily living and enhance assistant caregiving should be emphasized on future interventions to reduce caregiver burden with the final objective of improving their quality of life.
