使用回归方法从医学结局研究36项简表健康调查（SF-36）中选择12个项目并进行评分，以重现美国普通人群（n = 2，333）的身体健康总评量表和心理健康总评量表。由此产生的12项简表（SF-12）在SF-36身体健康总评和SF-36心理健康总评评分的预测中分别达到了0.911和0.918的多个R平方。当在医学结局研究中交叉验证时，用于对两个组成部分（身体组成部分总结和心理组成部分总结）的12项版本进行评分的一般人群评分算法在SF-36身体组成部分总结和SF-36心理组成部分总结中的R平方分别为0.905和0.938。在一般美国人群（n = 232）中，观察到12项身体健康总评和12项心理健康总评的重测（2周）相关性分别为0.89和0.76。先前发表的36项简短量表和总结测量的20项横截面和纵向经验有效性测试被复制用于12项身体成分总结和12项精神成分总结，包括已知在身体和精神状况、急性症状、年龄和老化的存在和严重性方面不同或变化的患者组之间的比较，自我报告的1年健康变化和抑郁症的恢复。在14个有效性测试，涉及物理标准，相对有效性估计为12个项目的身体成分总结范围从0.43至0.93（中位数= 0.67）相比，最好的36个项目的简短的规模。在涉及心理标准的6项测试中，12项心理成分总结的相对有效性估计值范围为0.60至1.07（中位数= 0.97），相对于最佳的36项简表量表。2个汇总指标的平均得分，以及基于12项简表的8个量表中大多数量表的平均得分，与36项简表的平均得分密切相关，尽管12项简表的标准误几乎总是较大。
Regression methods were used to select and score 12 items from the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) to reproduce the Physical Component Summary and Mental Component Summary scales in the general US population (n = 2,333). The resulting 12-item short-form (SF-12) achieved multiple R squares of 0.911 and 0.918 in predictions of the SF-36 Physical Component Summary and SF-36 Mental Component Summary scores, respectively. Scoring algorithms from the general population used to score 12-item versions of the two components (Physical Component Summary and Mental Component Summary) achieved R squares of 0.905 with the SF-36 Physical Component Summary and 0.938 with the SF-36 Mental Component Summary when cross-validated in the Medical Outcomes Study. Test-retest (2-week) correlations of 0.89 and 0.76 were observed for the 12-item Physical Component Summary and the 12-item Mental Component Summary, respectively, in the general US population (n = 232). Twenty cross-sectional and longitudinal tests of empirical validity previously published for the 36-item short-form scales and summary measures were replicated for the 12-item Physical Component Summary and the 12-item Mental Component Summary, including comparisons between patient groups known to differ or to change in terms of the presence and seriousness of physical and mental conditions, acute symptoms, age and aging, self-reported 1-year changes in health, and recovery from depression. In 14 validity tests involving physical criteria, relative validity estimates for the 12-item Physical Component Summary ranged from 0.43 to 0.93 (median = 0.67) in comparison with the best 36-item short-form scale. Relative validity estimates for the 12-item Mental Component Summary in 6 tests involving mental criteria ranged from 0.60 to 1.07 (median = 0.97) in relation to the best 36-item short-form scale. Average scores for the 2 summary measures, and those for most scales in the 8-scale profile based on the 12-item short-form, closely mirrored those for the 36-item short-form, although standard errors were nearly always larger for the 12-item short-form.
