12项健康调查（SF-12）是作为SF-36的较短替代方案开发的，用于大规模研究，特别是当整体身心健康是感兴趣的结果，而不是典型的八量表特征时。本研究的主要目的是评估SF-12希腊版本的有效性。一个分层的代表性样本（N = 1005）的希腊一般人口进行了采访。调查内容包括SF-36、EQ-5D以及社会人口学和健康相关特征的问题。使用标准US算法推导SF-12总分。采用因子分析验证SF-12各条目的假设成分结构。结构效度采用“已知群体”效度测试和聚合效度、发散效度进行研究，聚合效度和发散效度通过与EQ-5D维度的相关性进行评估。通过与SF-36总分进行比较来评估并行效度。根据性别、年龄、教育程度、社会经济地位、自我报告的健康问题和卫生服务利用情况，SF-12总分以预期的方式在受访者群体之间区分良好，从而提供了结构效度的证据。SF-36和SF-12总分之间的效应量差异通常较小（<0.2），支持同时（标准）效度。报告慢性疾病的受访者的平均PCS-12和MCS-12评分显著低于未报告慢性疾病的受访者（P < 0.001）。收敛和发散效度得到EQ-5D预期关系的支持。报告EQ维度的问题与较低的SF-12总分相关，支持同时效度。希腊SF-12的敏感性和复制的原始测量和概念模型进行了论证。结果提供了希腊SF-12的有效性的证据，并结合未来的研究解决重测信度和反应，支持其在希腊健康状况研究中的使用，作为一个简短的，但有效的，SF-36的替代品。
The 12-item Health Survey (SF-12) was developed as a shorter alternative to the SF-36 for use in large-scale studies, particularly when overall physical and mental health are the outcomes of interest instead of the typical eight-scale profile. The main purpose of this study was to assess the validity of the Greek version of the SF-12. A stratified representative sample (N = 1005) of the Greek general population was interviewed. The survey included the SF-36, the EQ-5D and questions on socio-demographic and health-related characteristics. SF-12 summary scores were derived using the standard US algorithm. Factor analysis was used to confirm the hypothesized component structure of the SF-12 items. Construct validity was investigated with "known groups" validity testing and via convergent and divergent validity, which in turn were assessed by the correlations with the EQ-5D dimensions. Concurrent validity was assessed by comparisons with SF-36 summary scores. SF-12 summary scores distinguished well, and in the expected manner, between groups of respondents on the basis of gender, age, education, socio-economic status, self-reported health problems and health services utilization, thus providing evidence of construct validity. Effect size differences between SF-36 and SF-12 summary scores were generally small (<0.2), supporting concurrent (criterion) validity. Significantly lower mean PCS-12 and MCS-12 scores were observed for respondents reporting chronic conditions compared to those without (P < 0.001). Convergent and divergent validity were supported by expected relationships with the EQ-5D. Reporting a problem in an EQ dimension was associated with lower SF-12 summary scores, supporting concurrent validity. Sensitivity of the Greek SF-12 and replication of the original measurement and conceptual model were demonstrated. The results provide evidence on the validity of the Greek SF-12 and, in conjunction to future studies addressing test-retest reliability and responsiveness, support its use in Greek health status studies as a brief, yet valid, alternative to the SF-36.
