PURPOSE: The survival rate of cervical cancer is increasing due to early diagnosis and timely treatment. As a result, the availability of a valid and reliable general HRQoL is important. The purpose of this study was to evaluate the psychometric properties of the EuroQol questionnaire (EQ-5D) in patients with cervical cancer in Taiwan. METHOD: Outpatients with cervical cancer were recruited from three medical centers across Taiwan. Test-retest reliability and ceiling effect were evaluated. Construct validity including convergent and discriminate validities were examined using the EORTC QLQ C-30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) and the clinical indicators of the functional performance assessment using the Karnofsky Performance Scale (KPS) and disease status. RESULTS: A total of 530 patients completed the questionnaire. The intraclass correlation coefficient for the EQ-5D index was 0.83, and the Cohen's kappa values for the EQ-5D dimensions ranged from 0.54 to 0.73. The EQ-5D index and VAS scores were higher for patients with a higher KPS score and disease-free status. The EQ-5D index was strongly correlated with all EORTC QLQ-C30 functioning scales. CONCLUSION: The EQ-5D questionnaire is reliable and valid for the assessment of health-related quality of life in patients with cervical cancer in Taiwan.
目的:由于早期诊断和及时治疗,宫颈癌的存活率正在提高。因此,拥有有效的、可靠的一般健康相关生活质量(HRQoL)非常重要。本研究旨在评估台湾宫颈癌患者的欧洲生命质量五维问卷(EQ-5D)的心理测量特性。
方法:从台湾的三家医疗中心招募宫颈癌门诊患者。评估重测信度和天花板效应。使用 EORTC QLQ C-30(欧洲癌症研究与治疗组织生活质量问卷)和卡氏功能状态量表(KPS)及疾病状况的功能表现评估的临床指标,评估包括聚合效度和区分效度在内的结构效度。
结果:共有 530 名患者完成了问卷调查。EQ-5D 指数的组内相关系数为 0.83,EQ-5D 维度的 Cohen's kappa 值范围为 0.54 至 0.73。KPS 评分和无疾病状态较高的患者的 EQ-5D 指数和 VAS 评分较高。EQ-5D 指数与 EORTC QLQ-C30 所有功能量表均具有强烈相关性。
结论:EQ-5D 问卷可可靠有效地评估台湾宫颈癌患者的健康相关生活质量。
