目的：SF-36简表（SF-36）总分的双成分因素结构可能在全球范围内无效。我们研究了日本SF-36评分的三成分模型。研究设计和设置：SF-36评分来自日本人口的代表性样本。采用因子分析和结构方程模型。双成分模型给出了身体成分汇总（PCS）评分和心理成分汇总（MCS）评分。三成分模型给出了PCS、MCS和第三成分的分数，我们称之为角色成分总结（RCS）分数。这些与外部critics.Results：在三个组件模型，RCS是密切相关的角色，身体，社会功能，和角色情感分量表，而PCS和MCS与身体功能和心理健康分量表，如预期的。三组分模型的拟合优度指数为0.945，双组分模型的拟合优度指数为0.935。PCS区分共病条件分层组之间，和MCS区分心理抑郁分层组之间。结论：三成分模型比二成分模型更能反映PCS和MCS评分。需要RCS验证测试的标准。(C)2011 Elsevier Inc.

Objective: The two-component factor structure underlying Short Form-36 (SF-36) summary scores may not be valid worldwide. We studied a three-component model of SF-36 scores in Japan.Study Design and Setting: The SF-36 scores came from representative samples of the population of Japan. Factor analysis and structural equation modeling were used. The two-component model gave physical component summary (PCS) scores and mental component summary (MCS) scores. The three-component model gave scores on the PCS, the MCS, and also on the third component, which we call the role component summary (RCS) score. These were evaluated with external criteria.Results: In the three-component model, the RCS was strongly associated with the role-physical, social functioning, and role-emotional subscales, whereas the PCS and MCS were associated with the physical functioning and mental health subscales, as expected. The goodness-of-fit index was 0.945 for the three-component model and 0.935 for the two-component model. The PCS discriminated between groups stratified by comorbid conditions, and the MCS discriminated between groups stratified by psychological depression. Absence from work was associated with both PCS and RCS.Conclusion: The three-component model is better than the two-component model, and it provides more useful PCS and MCS scores. Criteria for validation testing of the RCS are needed. (C) 2011 Elsevier Inc. All rights reserved.
