SF-36量表在良性前列腺增生症患者生命质量研究中的信度、效度和反应度评价

Assessment of Reliability,Validity and Response of SF-36 in Measuring the Quality of Life of Benign Prostate Hyperplasia Patients

目的评价SF-36量表在中国良性前列腺增生症患者中的适用性。方法随机抽取确诊的良性前列腺增生症患者219例,患者自填问卷完成SF-36量表,通过统计学检验,评价量表的信度、效度和反应性。结果SF-36量表分半信度0.95,各维度及总表的Cronbachα系数均大于0.7。因子分析产生2个公因子,分别代表生理和心理方面。量表与IPSS症状评分和单条目自感健康相关较好(相关系数分别为-0.54和0.79)。量表能够区分不同年龄、疾病严重程度及治疗前后患者的生命质量。结论SF-36量表适于在中国良性前列腺增生症患者中运用。

Objective To assess the applicability of the SF-36 scales in measuring the quality of life of chinese benign prostate hyperplasia patients. Methods 219 patients selected by random sampling completed SF-36 scales by self-administration.The reliability,validity and response were assessed by statistical tests.Result The split-half reliability of the scales was 0.95,and all of the Cronbach α coefficients were above 0.7.A physical factor and a psychological factor were identified by factor analysis.The scales correlated IPSS symptom grade and single-item perceived-health well(the correlation coefficients were-0.54 and 0.79).The scales could distinguish the QOL of different patients in terms of age,severity of disease and treatment status.The QOL of patients was obviously improved after therapy.Conclusion The SF-36 scales is applicable for measuring the quality of life of chinese benign prostate hyperplasia patients.
