Background: European Organization for Research and Treatment quality of life (QOL) questionnaire (QLQ-C30) has been used frequently and many language versions have been developed, including the simplified Chinese version. It is important to study psychometric properties of the simplified Chinese version from the clinical standpoint. Patients and methods: The simplified Chinese version of the QLQ-C30 was used in a longitudinal study of 600 patients with five types of cancer: lung, breast, head and neck, colorectal, and stomach. The psychometric properties of the scale were evaluated by indicators of validity and reliability coefficients such as Cronbach's α and Pearson's correlation coefficient r, standardized response mean (SRM), correlational analysis, t-tests, and structural equation models. Results: Correlation and structural equation model analyses confirmed good construct validity with root mean square error of approximation 0.054, standardized root mean square residual 0.037, non-normed fit index 0.972, and comparative fit index 0.980. The α coefficients for all domains are >0.7 except for cognitive functioning (0.49). The test–retest reliability coefficients for most domains are >0.80 except for appetite loss (0.77) and diarrhea (0.75). The QOL score changes after treatments were of statistical significance with higher or moderate SRM in most domains. Conclusion: The simplified Chinese version of QLQ-C30 has good validity, reliability, and responsiveness and can be used to measure QOL for Chinese cancer patients.

Background: Despite the widespread application of the Chinese version of Symptom Check List 90 (SCL-90) amongst undergraduate students, researchers have not thoroughly evaluated its psychometric features with representative samples of Chinese undergraduate students. Aim: To evaluate its psychometric properties based on a large, representative sample of Chinese undergraduate students. Methods: A total of 4456 Chinese undergraduate students (age range = 17–25 years) completed the SCL-90. Correlation analysis, confirmatory factor analysis and structural equation modeling were used to evaluate its reliability and validity. Results: The evidence for item-total correlations, internal consistency reliability, intraclass correlation coefficients and composite reliability, and the hypothesized factor structure was satisfactory. The evidence for convergent validity was acceptable; however, the evidence for discriminant validity was not satisfactory. Conclusion: Based on a large, representative sample of Chinese undergraduate students, the Chinese version of the SCL-90 revealed both strengths and limitations, suggesting the need for further research.

Background: The SF‐36 is widely used as a significant health outcome or quality of life indicator and validated in many languages versions including Chinese. But the Chinese version of the SF‐36 (CSF‐36) is rarely used for those patients with hypertension, coronary heart diseases, chronic gastritis and peptic ulcer in China. Therefore, the CSF‐36 needs to be validated in patients with chronic diseases. Objectives: This paper is aimed to validate the CSF‐36 using an in‐patient sample of four chronic diseases from mainland China, with focusing on psychometric properties. Methods: The CSF‐36 was used in a longitudinal study consisting of 534 patients in these four chronic disease groups. The psychometric properties of the scale were evaluated by indicators such as validity and reliability coefficients Cronbach α, Pearson r, standardized response mean employing correlational analyses, multi‐trait scaling analysis, t‐tests, factor analyses and structural equation models. Results: Test–retest reliability coefficients for all domains were higher than 0.80 with a range of 0.83 to 0.96; the internal consistency (α) for most domains was higher than 0.70. Five of the eight domains as well as the Physical and Mental Health subscale summaries all had statistically significant changes after treatment with the SRM ranging from 0.18 to 0.28. Conclusion: The CSF‐36 showed good validity and reliability but small responsiveness when used in patients. It is a good and useful instrument for patients with chronic disease at some situations.

Chinese economic development has led to a significant rise in internal migration over the last 20 years, including large numbers of elderly. When elderly Chinese people migrate, they still register their residency to their place of origin and often do not register with the new administrative office at the destination due to the household registration (hukou) system in China. Thus, most of these migrant elderly do not receive full social services, possibly leading to poor subjective well-being. This study aims to qualitatively examine the level of subjective well-being and its determinants among migrants and local elderly in Dongguan City of Guangdong province, one of the most rapid economically developing areas in China. We also present the results of in-depth interviews among 27 elderly, 15 elderly migrants and 12 local elderly living in Dongguan. The results reveal that the overall subjective well-being of the two groups were good. Most migrants believed their well-being had remained stable or even improved over time due to family reunion and a better physical environment. Elderly’s most valuable needs and the main reason of migration is family reunion; however, inadequacy of social support, including community support and government support (e.g., gift during holiday season, free health examination, healthcare expenditure reimbursement), cannot be neglected for maintaining a good level of well-being. The well-being of migrant elderly can be further enhanced by promoting social services and welfare, recreational activities, and enhancing healthcare reimbursement in their new home.
