“…Regarding the sub-scale scores, the floor effects (i.e., the percentage of participants with the lowest sub-scale score or worse health status) were very small. Although the ceiling effects (i.e., the percentage of participants with the highest sub-scale score or best health status) were relatively large, our percentages were comparable to those reported in a previous study on SF-12 using a Chinese population [26]. The SF-8 was designed to measure the impact of health problems on HRQOL.…”

BackgroundThe Short Form-8 (SF-8) is a widely used instrument for measuring health-related quality of life (HRQOL). The purpose of the current study is to evaluate the reliability and validity of the Chinese version SF-8 using a large, representative sample of city residents in mainland China.MethodsWe surveyed residents of 35 major cities in China using random digit dialing of both landlines and cell phones. We adopted a multi-stage stratified sampling scheme and selected a probability sample of 10,885 adults. Internal consistency reliability of the SF-8 was evaluated with item-total correlations and Cronbach’s alphas. Construct validity was assessed with factor analysis. Known-groups validity was examined based on known HRQOL differences in age, gender, income, and overall quality of life.ResultsWe showed that SF-8 has very good internal consistency reliability and known-groups validity. Our results also confirmed that the traditional 2-factor structure of SF-8 (physical and mental health) is reasonable among Chinese city residents. Further, we showed that a 3-factor model (physical, mental, and overall health) fit the data better than the traditional 2-factor model.ConclusionsThis study is the first to confirm the traditional 2-factor structure of SF-8 using a large, representative sample from China. We have shown that the SF-8 Chinese version is feasible, reliable, and valid. Our findings support the use of the SF-8 summary scores for assessing general HRQOL among Chinese. Future studies may further explore the possibility of a 3-factor structure for the SF-8 among the Chinese population.

“…Psychometric properties of the SF-12 v2 in the Americans and Chinese adolescents have been presented [6, 23]. In terms of convergent and discriminant validity, all of the hypothesized item-component correlations were 0.30 or greater, and hypothesized item-component correlations were significantly higher than the alternative item-component correlations in previous publications [17], but, the study by Jakobsson et al showed that item-component correlations argued against the suggested structure in a general elderly population (aged 75+) [7].…”

BackgroundThe psychometric properties of the Korean Short Form-12 Health Survey, version 2 (SF-12 v2) have not been assessed in the general population. Therefore, the aim of our study was to evaluate the psychometric properties of the Korean version of the SF-12 v2 in the general population and to provide SF-12 v2 domain scores according to the general characteristics of the study population.MethodsA total of 1,000 participants from the general Korean population were recruited using a multistage quota sampling method. Psychometric properties were evaluated by descriptive statistics, validity, reliability, and exploratory factor analysis.ResultsItem convergent and discriminant validity met the criteria established by the instrument developer. In the known-group comparison, male gender, age <60 years, high educational status, and absence of any comorbidity were significantly associated with high scale scores. The reliability of all SF-12 v2 items was 0.88.ConclusionsThe findings of this study generally support the idea that the Korean SF-12 v2 is a feasible, valid, and reliable instrument for assessing health-related quality of life in the general population. The SF-12 v2 seems to be a viable alternative health-related quality of life instrument for the Korean population.

“…We adopted the CFA in lieu of exploratory factor analysis because the two-scale structure has been established in the West, but its applicability in Chinese had yet to be assessed. In addition, the exploratory factor analysis may be influenced by methods effects, such as the format of the items and choices of response, rather than the underlying latent scale structure (Fong et al, 2010). Hence, the CFA was performed, for the first time, to confirm the validity of the scale structure in our Chinese sample.…”

“…Cultural differences between Western societies and the Chinese have brought different scale structures of self-reported instruments for the Chinese and other ethnic groups (Fong et al, 2010). Hence, the reliability and construct validity of the SSSC administered in Chinese needed to be examined to facilitate the evaluation of learning outcomes of medical simulation courses in Chinese.…”
