Reliability and validity of the English (Singapore) and Chinese (Singapore) versions of the Short-Form 36 version 2 in a multi-ethnic Urban Asian population in Singapore

Purpose

We aimed to evaluate the measurement properties of the Singapore English and Chinese versions of the Short-Form 36 version 2 (SF-36v2) Questionnaire, an improved version of the widely used SF-36, for assessing health-related quality of life (HRQoL) in a multi-ethnic urban Asian population in Singapore.

Methods

SF-36v2 scores and data on medical history, demographic and lifestyle factors from the Singapore Prospective Study Programme were analyzed. Convergent and divergent validity, internal consistency, floor and ceiling effects, known group validity and factor structure of the SF-36v2 were assessed for the English and Chinese versions, respectively.

Results

Complete data for 4,917 participants (45.8 %) out of 10,747 eligible individuals were analyzed (survey language: 4,115 English and 802 Chinese). Item-scale correlations exceeded 0.4 for all items of the English SF-36v2 and for all except one item of the Chinese SF-36v2 (bathe and dress: item-scale correlation: 0.36). In the English SF-36v2, Cronbach’s alpha exceeded 0.70 for all scales. In the Chinese SF-36v2, Cronbach’s alpha exceeded 0.7 on all scales except social functioning (Cronbach’s alpha: 0.68). For known groups validity, respondents with chronic medical conditions expectedly reported lower SF-36v2 score on most English and Chinese SF-36v2 scales. In confirmatory factor analysis, the Singapore three-component model was favored over the United States two-component and Japan three-component models.

Conclusions

The English and Chinese SF-36v2 are valid and reliable for assessing HRQoL among English and Chinese-speaking Singaporeans. Test–retest reliability and responsiveness of the English and Chinese SF-36v2 in Singapore remain to be evaluated.     

A Chinese version of the Sleep Apnea Quality of Life Index was evaluated for reliability, validity, and responsiveness

OBJECTIVE: Obstructive sleep apnea (OSA) is a common disorder in many ethnic populations. Patients with OSA have impaired health-related quality of life (HRQOL). No sleep apnea-specific HRQOL measure has been validated in Chinese patients. STUDY DESIGN AND SETTING: A cross-sectional sample of 106 Chinese OSA patients and a longitudinal sample of 51 patients in Hong Kong completed a Chinese (Cantonese) version of SAQLI for assessment of its acceptability, scaling assumptions, reliability, validity, and responsiveness. RESULTS: The instrument was understood and seen as relevant by 97% of subjects. Internal consistency, test-retest reliability, item-scale convergent validity and discriminatory validity, and construct validity were good to excellent. Construct validity was confirmed by significant correlations with SF-36 subscale scores. However, factor analysis showed that only items of daily functioning and symptom domains all loaded on the hypothesized scales. Longitudinal data showed that SAQLI was more responsive than SF-36 to changes after treatment. CONCLUSION: Hence, this version of SAQLI was an acceptable, psychometrically valid, and responsive HRQOL measure for evaluating impact of illness and treatment effectiveness in Chinese OSA patients.     

Equivalence of Chinese and US–English Versions of the SF-36 Health Survey

This study evaluated the equivalence of Chinese and US–English versions of the SF-36 Health Survey in a convenience sample of 309 Chinese nationals bilingual in Chinese and English living in a US city. Snowball sampling was used to generate sufficient sample size. Internal consistency, test–retest, and equivalent-forms reliability were estimated. Patients were randomized to one of four groups: (1) English version completed first, followed by Chinese version (same occasion); (2) Chinese version completed first, followed by English version (same occasion); (3) English version completed once and then again 1-week later; (4) Chinese version completed once and then again 1-week later. Internal consistency reliability estimates for the Chinese and US–English versions of the SF-36 scales ranged from 0.60 to 0.88; test–retest reliability estimates (1 week time interval) ranged from 0.67 to 0.90. Reliability estimates for corresponding Chinese and US–English SF-36 scales tended to be similar and not significantly different. Equivalent-forms reliability estimates (product–moment correlations) ranged from 0.81 to 0.98. Mean SF-36 scale scores were comparable for both versions of the instrument. This study provides support for the equivalence of the Chinese and US–English versions of the SF-36.     

Reliability and validity of the Norwegian version of the Functional Outcomes of Sleep Questionnaire

The aim of this study was to validate the Norwegian version of a self-administered 30-item quality of life questionnaire designed to assess disorders of excessive sleepiness, the Functional Outcomes of Sleep Questionnaire (FOSQ). In total 226 patients previously evaluated for obstructive sleep apnea were included in the study. The patients received a postal questionnaire with the FOSQ, the Short Form 36 (SF-36) questionnaire, and a scale for assessment of excessive daytime sleepiness, the Epworth sleepiness scale (ESS). Among the 178 respondents, all five subscales of the FOSQ showed good internal consistency reliability (Cronbach's alpha = 0.84-0.93). Test-retest on average 18 days apart was satisfactory with intraclass correlation coefficients ranging from 0.61 to 0.86. The pattern of Spearman's rank correlation coefficients between FOSQ scales and related and unrelated scales SF-36 scales gave support to the construct validity of the FOSQ. In conclusion, the Norwegian translation of the FOSQ showed satisfactory internal consistency reliability, test-retest reliability and construct validity, in line with the original version.     

The Short Form Health Survey (SF-36): Translation and validation study of the Iranian version

This was a large population-based study to develop and validate the Iranian version of the Short Form Health Survey (SF-36) for use in health related quality of life assessment in Iran. A culturally comparable questionnaire was developed and pilot tested. Then, the Iranian version of the SF-36 was administered to a random sample of 4163 healthy individuals aged 15 years and over in Tehran. The mean age of the respondents was 35.1 (SD=16.0) years, 52% were female, mostly married (58%) and the mean years of their formal education was 10.0 (SD=4.5). Reliability was estimated using the internal consistency and validity was assessed using known groups comparison and convergent validity. In addition factor analysis was performed. The internal consistency (to test reliability) showed that all eight SF-36 scales met the minimum reliability standard, the Cronbachs coefficients ranging from 0.77 to 0.90 with the exception of the vitality scale (=0.65). Known groups comparison showed that in all scales the SF-36 discriminated between men and women, and old and the young respondents as anticipated (all p values less than 0.05). Convergent validity (to test scaling assumptions) using each item correlation with its hypothesized scale showed satisfactory results (all correlation above 0.40 ranging from 0.58 to 0.95). Factor analysis identified two principal components that jointly accounted for 65.9% of the variance. In general, the Iranian version of the SF-36 performed well and the findings suggest that it is a reliable and valid measure of health related quality of life among the general population.     

Chinese SF-36 Health Survey: translation,cultural adaptation,validation, and normalisation

STUDY OBJECTIVE: To develop a self administered Chinese (mainland) version of the Short-Form Health Survey (SF-36) for use in health related quality of life measurements in China. DESIGN: A three stage protocol was followed including translation, tests of scaling construction and scoring assumptions, validation, and normalisation. SETTING: 1000 households in 18 communities of Hangzhou. PARTICIPANTS: 1688 respondents recruited by multi-stage mixed sampling. Main results: The assumption of equal intervals was violated for the vitality and mental health scales. The recoded item values were used to calculate scale scores. The clustering and ordering of item means was the same as that of the source and other two Chinese versions. The items in each scale had similar standard deviations except those in the physical functioning, boduily pain, social functioning scales. The item hypothesised scale correlations were identical for all except the social functioning and vitality scales. Convergent validity and discriminant validity were satisfactory for all except the social functioning scale. Cronbach's alpha coefficients ranged from 0.72 to 0.88 except 0.39 for the social functioning scale and 0.66 for the vitality scale. Two weeks test-retest reliability coefficients ranged from 0.66 to 0.94. Factor analysis identified two principal components explaining 56.3% of the total variance. The Chinese SF-36 could distinguish known groups. CONCLUSIONS: This study suggested that the Chinese (mainland) version of the SF-36 functioned in the general population of Hangzhou, China quite similarly to the original American population tested. Caution is recommended in the interpretation of the social functioning and vitality scales pending further studies.     

The Spanish version of the Short Form 36 Health Survey: a decade of experience and new developments

OBJECTIVE: The Short Form-36 Health Survey (SF-36) is one of the most widely used and evaluated generic health-related quality of life (HRQL) questionnaires. After almost a decade of use in Spain, the present article critically reviews the content and metric properties of the Spanish version, as well as its new developments. METHODS: A review of indexed articles that used the Spanish version of the SF-36 was performed in Medline (PubMed), the Spanish bibliographic databases IBECS and IME. Articles that provided information on the measurement model, reliability, validity, and responsiveness to change of the instrument were selected. RESULTS: Seventy-nine articles were found, of which 17 evaluated the metric characteristics of the questionnaire. The reliability of the SF-36 scales was higher than the suggested standard (Cronbach's alpha) of 0.7 in 96% of the evaluations. Grouped evaluations obtained by meta-analysis were higher than 0.7 in all cases. The SF-36 showed good discrimination among severity groups, moderate correlations with clinical indicators, and high correlations with other HRQL instruments. Moreover, questionnaire scores predicted mortality and were able to detect improvement due to therapeutic interventions such as coronary angioplasty, benign prostatic hyperplasia surgery, and non-invasive positive pressure home ventilation. The new developments (norm-based scoring, version 2, the SF-12 and SF-8) improved both the metric properties and interpretation of the questionnaire. CONCLUSIONS: The Spanish version of the SF-36 and its recently developed versions is a suitable instrument for use in medical research, as well as in clinical practice.     

Internal consistency,reproducibility, responsiveness,and construct validity of the Chinese (HK) version of the asthma quality of life questionnaire

The purpose of this study was to test the acceptability, psychometric properties and construct validity of a Chinese translation of the Asthma Quality of Life Questionnaire (AQOL) and to determine whether it has any advantage over the Chinese (HK) version of the generic MOS SF-36 Health Survey that has been validated on Chinese in Hong Kong. Fifty-two patients with asthma were interviewed using the Chinese (HK) AQOL and the Chinese (HK) SF-36. Thirty-four of the 52 patients were interviewed a second time 6 months later using the same questionnaires. The Cronbach's α coefficients were above 0.7 for all four domains of the AQOL questionnaire. Significant correlations were found between the scores of each of the four domains of the Chinese (HK) AQOL and forced expiratory volume in 1 s (FEV₁) (%predicted) during the initial visit and between changes in the mean scores of most of the domains of Chinese (HK) AQOL and changes in FEV₁ between visits. The Chinese (HK) AQOL was found to be reproducible in those with stable asthma, and for those whose asthma severity changed between visits, there was significant change in one of the domains. It can detect differences in quality of life in asthma patients of varying severity. We conclude that the Chinese (HK) translation of the AQOL is reliable, valid, reproducible and discriminative and can be used to supplement generic instruments in evaluating the quality of life of patients with asthma.
