SF-36量表评价Graves病患者生存质量信度和效度的研究

目的评价SF-36量表测定Graves病患者生存质量的信度和效度。方法应用SF-36量表对113例Graves病患者的生存质量进行测评，并从中随机抽取20例于2周后复测，对测定结果进行效度和信度分析。结果量表总体Cronbachα系数为0．775，各个维度的Cronbachα系数的范围为0．571—0．868；评价分半信度的Spearman—Brown系数为0．946；重测信度中两次测量的Pearson相关系数为0．87；用因子分析法对量表进行结构效度的评价，得到的两个公因子共解释了59．71％的方差。标准效度中患者健康自评总分与量表总分的相关系数r为0．726。结论SF-36量表评价Graves病患者生存质量的信效度较高，可应用于此病生存质量的测评。

Evaluation of Reliability and validity of SF-36 in patients with Graves disease

Objective To evaluate the reliability and validity of SF-36 (36-item Short Form Health Survey) in patients with Graves disease. Methods 113 patients with Graves disease were assessed using SF-36,20patients were reassessed randomly after 2 weeks, and the data was used to analyze reliability and validity. Results The cronbach' s α coefficient of internal consistency was 0.775. Cronbach' s α coefficient of 8 domains ranged from 0.571 to 0.868; the Spearman-Brown coefficient which assessed split-half reliability was 0.946; two weeks later 20 patients were choosen at random to be assessed again, the Pearson correlation coefficient of testretest reliability for the overall questionnair were 0.87. Construct validity were examined, and factor analysis showed two common factors which accounted for 59.71% of total variance were extracted. In criterion validity,the correlation coefficient of self-rated health and the total scores in the scale table was 0.726. Conclusion SF-36 has good reliability and validity and is useful for measurement and assessment of patients with Graves disease.
