癌症末期生活质量量表（Quality of Life at the End of Life-Cancer Scale，简称QQ-EC）是一种用于评估癌症患者生命末期生活质量的自我报告工具。目的检验Q-EC-J的信度和效度。广泛性焦虑症-7、Rosenberg自尊量表、感知社会支持的多维量表、癌症治疗功能评估-一般量表和慢性疾病治疗功能评估-精神问卷。我们进行了验证性因素分析的四个结构的ESTA-EC和探索性因素分析的ESTA-EC-J的内部一致性进行了评估，使用Cronbach的α系数和效度进行了检查，通过计算相关scales. ResultsESTA-EC结构的原始ESTA-EC结构的不适合。探索性因素分析结果显示，大学生自我效能感的结构为三因素结构，Cronbach’s α值为0.68 ~ 0.88。各分量表与抑郁、焦虑呈负相关。每个分量表都与相关测量相关：“症状控制”与“身体健康”;“接受疾病和生命”与“社会和家庭健康”和“意义/和平”;“为生命结束做准备”与“情感健康”和“意义/和平”。结论该量表具有较好的信度和效度。中国-欧盟-日本和中国-欧盟之间的因素结构的差异可能是由于文化因素。研究结果表明，利用EST-EC-J有助于改善日本晚期癌症的研究和临床护理。
ContextThe Quality of Life at the End of Life-Cancer Scale (QUAL-EC) is a self-reported instrument to assesses the quality of life of patients with cancer near the end of life.ObjectiveTo test the reliability and validity of the QUAL-EC-J, a Japanese translated version of the QUAL-EC.MethodsA total of 179 Japanese patients with advanced cancer completed the QUAL-EC-J, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Rosenberg Self-Esteem Scale, Multidimensional Scale of Perceived Social Support, Functional Assessment of Cancer Therapy-General Scale, and Functional Assessment of Chronic Illness Therapy-Spiritual questionnaires. We performed confirmatory factor analysis of the four structures of the QUAL-EC and exploratory factor analysis of the QUAL-EC-J. Internal consistency was assessed using Cronbach's α coefficient and validity was examined by calculating correlations with relevant scales.ResultsConfirmatory factor analysis showed an inadequate fit to the original QUAL-EC structure. Exploratory factor analysis revealed a three-factor structure of the QUAL-EC-J, with Cronbach's α values of 0.68–0.88. All subscales were negatively correlated with depression and anxiety. Each subscale was correlated with related measures: “symptom control” with “physical well-being”; “acceptance of disease and life” with “social and family well-being” and “meaning/peace”; and “preparation for end of life” with “emotional well-being” and “meaning/peace.”ConclusionsThe QUAL-EC-J has a three-factor structure with acceptable reliability and sufficient validity. Differences in the factor structure between the QUAL-EC-J and the QUAL-EC may be due to cultural factors. Study findings suggest that utilization of the QUAL-EC-J could help to improve research and clinical care in advanced cancer in Japan.
