We aimed to develop a new scale for use in Japan, called the "Quality of Life of Family Caregivers of Advanced Cancer Patients Scale (QFCS)" and to examine its psychometric properties.
A draft scale was extracted based on qualitative inductive and deductive analyses, and its content validity and surface validity were investigated. Its psychometric properties were examined.
The QFCS consists of 30 items comprising four factors. Cronbach's α was 0.92 and the intraclass correlation coefficient was 0.90. Correlation coefficients between the total QFCS score and eight subscale scores of the revised Medical Outcomes Study 12-Item Short Form Survey Instrument were s = 0.22-0.65 ( < 0.01-0.05). The Physical Component Summary was = 0.29 ( < 0.01), and the Mental Component Summary was = 0.67 ( < 0.01). Correlation coefficients between the QFCS total score and four subscale scores of the Caregiver Quality of Life Index-Cancer (CQOLC) were = 0.27-0.59 ( <0 .01) and the CQOLC total score was = 0.65 ( <0 .01).
Our results suggest that the QFCS exhibited acceptable psychometric properties in measuring the quality of life of family caregivers of patients with advanced cancer. Future research is needed to evaluate the effectiveness and quality of family support using the QFCS.
我们旨在开发一种新的适用于日本的量表，即“晚期癌症患者家庭照顾者生活质量量表（QFCS）”，并检验其心理测量特性。
基于定性归纳和演绎分析提取量表草案，并调查其内容效度和表面效度。检验其心理测量特性。
QFCS由30个项目组成，包含四个因子。克朗巴哈α系数为0.92，组内相关系数为0.90。QFCS总分与修订后的医学结局研究12项简短形式调查问卷的八个子量表得分之间的相关系数为s = 0.22 - 0.65（<0.01 - 0.05）。生理健康分量表为s = 0.29（<0.01），心理健康分量表为s = 0.67（<0.01）。QFCS总分与照顾者生活质量指数-癌症（CQOLC）的四个子量表得分之间的相关系数为s = 0.27 - 0.59（<0.01），CQOLC总分与QFCS总分的相关系数为s = 0.65（<0.01）。
我们的结果表明，QFCS在测量晚期癌症患者家庭照顾者的生活质量方面表现出可接受的心理测量特性。未来需要开展研究以评估使用QFCS进行家庭支持的有效性和质量。
