To find out whether the SF-36 physical and mental health summary (PCS and MCS) scales are valid and equivalent in the Chinese population in Hong Kong (HK).
The SF-36 data of a cross-sectional study on 2,410 Chinese adults randomly selected from the general population in HK were analyzed.
The hypothesized two-factor structure of the physical and mental health summary scales (PCS and MCS) was replicated and the expected differences in scores between known morbidity groups were shown. The internal reliability coefficients of the PCS and MCS scales ranged from 0.85 to 0.87. The effect size differences between the U.S. standard and HK-specific PCS and MCS scores were mostly <0.5. The effect size differences in the standard PCS and MCS scores of specific groups between the U.S. and H.K. populations were all <0.5.
The PCS and MCS scales were applicable to the Chinese population in HK. The high level of measurement equivalence of the scales between the U.S. and H.K. populations suggests that data pooling between the two populations could be possible. To our knowledge, this is the first study to show that the SF-36 summary scales are valid and equivalent in an Asian population.
探究SF-36生理和心理健康概况量表（PCS和MCS）在中国香港人群中是否有效且等效。
对从香港普通人群中随机抽取的2410名中国成年人的横断面研究中的SF-36数据进行分析。
重复了生理和心理健康概况量表（PCS和MCS）的假设双因素结构，并显示了已知发病组之间预期的得分差异。PCS和MCS量表的内部信度系数在0.85至0.87之间。美国标准与香港特定的PCS和MCS得分之间的效应量差异大多<0.5。美国和香港人群中特定组的标准PCS和MCS得分的效应量差异均<0.5。
PCS和MCS量表适用于香港的中国人群。美国和香港人群之间量表的高度测量等效性表明，这两个人群之间的数据合并是可能的。据我们所知，这是第一项表明SF-36概况量表在亚洲人群中有效且等效的研究。
