下载PDF阅读器目的 评价美国SF-36中文版健康状况调查表用于鼻咽癌疗后长期存活者的适用性.方法 85例鼻咽癌疗后长期存活者通过电话或信访方式完成评价,相关分析、信度分析和因子分析等统计方法用于评价SF-36中文版的信度和效度.结果 分半信度为0.92,各领域克朗巴赫系数α均〉0.7,说明信度较好且各领域间有较好区分度.每个条目跟相关领域的相关系数都达到或接近0.5,并且各条目与所属领域相关系数均高于该条目与其他领域的相关系数,说明量表有较好的内容效度和区分效度.量表共提取6个主成分,基本反映了量表8个领域,累计方差贡献率为71.4%.8个领域提取2个公共因子,解释73.3%变异.SF-36中文版判别效度较好,能区分鼻咽癌患者和正常人群的生存质量.结论 SF-36中文版易于完成,具有较好的信度和效度,可应用于鼻咽癌疗后长期存活者生存质量的评价.

Objective To evaluate the reliability, validity and feasibility of the Chinese version of SF-36 health survey questionaire in long-term survivors of nasopharyngeal carcinoma （NPC）. Methods A total of 85 long-term NPC survivors completed the Chinese version of SF-36 by either telephone or mail survey. Correlation analysis, reliability analysis and factor analysis were performed to evaluate the reliability and validity of the scale. Results The Chinese version of SF-36 was easy to complete. The split-half reliability was 0. 92 and the Cronbach＇s ct coefficient among domains were all above 0. 70, which showed good reliability and discrimination capacity among domains. All the correlation coefficients between each item and its domain achieved or approached 0. 5, which were greater than those between the item and other domains. These results demonstrated that the Chinese version of SF-36 had good content validity and discriminatory validity. Six principal components were extracted from the scale, which could basically represent eight domains. The cumulative variance was 71.4%. Two common factors were extracted from the eight domains, which accounted for 73.3% of the variance. The Chinese version of SF-36 was able to detect differences in the quality of life between NPC patients and healthy populations. Conclusions The Chinese version of SF-36 has good feasibility, reliability and validity in evaluating the quality of life in long-term NPC
