This study aimed to assess the psychometric properties of the SF-12 questionnaire (in comparison to the EQ-5D questionnaire also), based on a survey conducted on a sample representing the general population of Poland.
The respondents completed Polish versions of health-related quality of life (HRQoL) questionnaires: SF-12, EQ-5D-5L, EQ VAS, and EQ-5D-3L, together with demographic and socioeconomic characteristic items. The following psychometric properties were analyzed: informativity power, ceiling and floor effects, reliability, and construct validity. We also conducted an exploratory factor analysis.
A total of 3,896 respondents (mean age 48.3 years, 53.2% female) were included in the analysis. The results showed exceptional informativity power of SF-12 items. We did not observe any ceiling and floor effects for the PCS and MCS components. The high values of the Cronbach's alpha coefficients confirmed the reliability of SF-12. Our hypothesis about lower scores for the summary components among older respondents, females and patients having declared diabetes was confirmed. The results of factor analysis also provided evidence for a positive assessment of construct validity.
Our results confirmed that the Polish version of the SF-12 questionnaire is a valid instrument for use in HRQoL assessment among the general population of Poland.
本研究旨在评估 SF-12 问卷（与 EQ-5D 问卷相比）的心理测量特性，该研究基于对波兰一般人群样本进行的调查。
受访者填写了波兰语版本的健康相关生活质量（HRQoL）问卷：SF-12、EQ-5D-5L、EQ VAS 和 EQ-5D-3L，以及人口统计学和社会经济特征项目。分析了以下心理测量特性：信息量、天花板和地板效应、可靠性和结构有效性。我们还进行了探索性因素分析。
共纳入 3896 名受访者（平均年龄 48.3 岁，53.2%为女性）进行分析。结果表明 SF-12 项目具有极好的信息量。我们没有观察到 PCS 和 MCS 分量的天花板和地板效应。Cronbach's alpha 系数的高值证实了 SF-12 的可靠性。我们关于年龄较大的受访者、女性和患有糖尿病的患者报告的综合成分得分较低的假设得到了证实。因子分析的结果也为结构有效性的正面评估提供了证据。
我们的结果证实，波兰语版的 SF-12 问卷是一种有效的工具，可用于评估波兰一般人群的 HRQoL。
