对9个欧洲国家（丹麦、法国、德国、意大利、荷兰、挪威、西班牙、瑞典和英国）的一般人群调查（n = 1483 - 9151）数据进行分析，以交叉验证SF-12健康调查问卷项目的选择和12项身体和精神成分汇总指标的评分算法。在每个国家，使用多元回归方法选择12个SF-36项目，这些项目最好地再现了SF-36健康调查的身心健康总分。然后用12个项目以三种方式估计总结分数：使用标准（美国- SF-12项目和评分算法;标准项目和国家特定评分;以及国家特定的12个项目和评分集。然后通过比较平均得分和积差相关性的强度，评价36项汇总测量与12项汇总测量的重复性。SF-36和SF-12（标准和国家特定）之间的积差相关性非常高，生理和心理汇总指标的范围分别为0.94-0.96和0.94-0.97。每个国家的平均36项汇总测量值和可比的12项汇总测量值在0.0至1.5分（中位数= 0.5分）范围内，并且在各年龄组之间具有可比性。由于使用SF-12和SF-36估计的概括性身体和心理健康指标之间高度一致，因此SF-12似乎将被证明是这些国家SF-36的实用替代品，用于大组比较，其中重点是整体身体和心理健康结局。(C)1998年爱思唯尔科学公司
Data from general population surveys (n = 1483 to 9151) in nine European countries (Denmark France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, and-the United Kingdom) were analyzed to cross-Validate the selection of questionnaire items for the SF-12 Health Survey and scoring algorithms for 12-item physical and mental component summary measures. In each country, multiple regression methods were used to select 12 SF-36 items that best reproduced the physical and mental health summary scores for the SF-36 Health Survey. Summary scores then were estimated with 12 items in three ways: using standard (U.S.-derived) SF-12 items and scoring algorithms; standard items and country-specific scoring; and country-specific sets of 12 items and scoring. Replication of the 36-item summary measures by the 12-item summary measures was then evaluated through comparison of mean scores and the strength of product-moment correlations. Product-moment correlations between SF-36 summary measures and SF-12 summary measures (standard and country-specific) were very high, ranging from 0.94-0.96 and 0.94-0.97 for the physical and mental summary measures, respectively. Mean 36-item summary measures and comparable 12-item summary measures were within 0.0 to 1.5 points (median = 0.5 points) in each country and were comparable across age groups. Because of the high degree of correspondence between summary physical and mental health measures estimated using the SF 12 and SF-36, it appears that the SF-12 will prove to be a practical alternative to the SF-36 in these countries, for purposes of large group comparisons in which the focus is on overall physical and mental health outcomes.
