介绍
本研究的目的是评估SF-12问卷在接受血液透析的伊朗患者样本中的有效性和可靠性。
材料和方法
来自伊朗赞詹透析中心的144例血液透析患者被纳入研究，并被要求完成SF-12和SF-36问卷。对来自总组的70名患者的样本进行初始重测信度评价，重测间隔为14天。可靠性估计的内部一致性和有效性进行了评估，使用已知组的比较和结构效度的患者组作为一个整体。使用线性回归分析评估SF-36的身体健康总评和心理健康总评评分与SF-12的相应总评评分之间的任何变化。此外，本研究亦以验证性因素分析萃取出问卷的因素结构。
结果
身体和精神成分总结的Cronbach α分别为0.89和0.90。SF-12在基于人口统计学和临床变量的患者亚组之间显示出良好的区分能力。验证性因素分析的原始两个因素的结构显示了良好的拟合指数（卡方= 23.30，自由度= 13），拟合优度指数= 0.96，和均方根误差的近似值= 0.079）。
结论
一般而言，SF-12具有良好的心理测量学特性，可在未来涉及接受血液透析的伊朗患者的研究中用作SF-36问卷的简化版本。
INTRODUCTION
The aim of the study was to assess the validity and reliability of the SF-12 questionnaire in a sample of Iranian patients undergoing hemodialysis.
MATERIALS AND METHODS
One hundred and forty-four hemodialysis patients were included from dialysis centers in Zanjan, Iran, and were asked to complete the SF-12 and SF-36 questionnaires. An initial test-retest reliability evaluation was performed on a sample of 70 patients from the total group, with a retest interval of 14 days. Reliability was estimated by internal consistency and validity was assessed using known-group comparisons and construct validity on the patient group as a whole. A linear regression analysis was used to assess any variation in the physical component summary and mental component summary scores of the SF-36 with the respective component summary scores of the SF-12. In addition, the factor structure of the questionnaire was extracted by performing a confirmatory factor analysis.
RESULTS
Cronbach alpha for physical and mental component summaries were 0.89 and 0.90, respectively. The SF-12 showed a good discriminatory ability between subgroups of patients based on demographic and clinical variables. The confirmatory factor analysis for the original two-factor structure showed a good fit index (chi2 = 23.30, degrees of freedom = 13), goodness-of-fit index = 0.96, and root mean squared error of approximation = 0.079).
CONCLUSIONS
In general, the SF-12 has good psychometric properties and can be used as a shorter version of the SF-36 questionnaire in future studies involving Iranian patients undergoing hemodialysis.
