Purpose: To develop the mapping functions from the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) scores onto the EQ-5D-5L and SF-6Dv2 utility values among the overweight and obese population in China.
Methods: A representative sample of the overweight and obese population in China stratified by age, sex, body mass index (BMI), and area of residence was collected by online survey and the sample was randomly divided into development (80%) and validation (20%) datasets. The conceptual overlap between the IWQOL-Lite and the EQ-5D-5L or SF-6Dv2 was evaluated by Spearman's correlation coefficients. Five models, including OLS, Tobit, CLAD, GLM, and PTM were explored to derive mapping functions using the development dataset. The model performance was assessed using MAE, RMSE, and the percentage of AE > 0.05 and AE > 0.1 in the validation dataset.
Results: A total of 1000 respondents (48% female; mean [SD] age: 51.7 [15.3]; mean [SD] BMI: 27.4 [2.8]) were included in this study. The mean IWQOL-Lite scores and the utility values of EQ-5D-5L and SF-6Dv2 were 78.5, 0.851, and 0.734, respectively. The best-performing models predicting EQ-5D-5L and SF-6Dv2 utilities both used IWQOL-Lite total score as a predictor in the CLAD model (MAE: 0.083 and 0.076 for the EQ-5D-5L and SF-6Dv2; RMSE: 0.125 and 0.103 for the EQ-5D-5L and SF-6Dv2; AE > 0.05: 20.5% and 27.5% for the EQ-5D-5L and SF-6Dv2; AE > 0.10: 9.5% and 15.0% for the EQ-5D-5L and SF-6Dv2).
Conclusion: CLAD models with the IWQOL-Lite total score can be used to predict both the EQ-5D-5L and SF-6Dv2 utility values among overweight and obese population in China.

Objectives: The CHROME-G is the first generic preference-based measure developed in China. This study aimed to validate and compare the psychometric properties of the CHROME-G with the EQ-5D-5L and SF-6Dv2 among the Chinese general population.
Methods: A representative sample of the Chinese general population in terms of age, gender, education, and urban/rural residence was recruited for an online survey.

Article Synopsis
- The study aimed to establish quality-adjusted life expectancy (QALE) norms for the Chinese population using health utility values from the EQ-5D-5L and SF-6Dv2 instruments.
- By combining these health utility norms with the latest Chinese National Life Tables, researchers calculated QALE estimates based on factors like age, sex, and urban/rural residence, applying various discount rates.
- Results revealed that QALE at birth differed between females and males, with rural populations generally showing lower QALE compared to urban ones, highlighting the importance of these norms for healthcare decision-making.
Validation of the Generic Version of China Health Related Outcomes Measures (CHROME-G) among individuals with type 2 diabetes in China.

Objective: The Generic Version of China Health Related Outcomes Measures (CHROME-G) was a new preference-based health-related quality of life (HRQoL) instrument designed specifically for the Chinese population. This study aimed to validate and compare measurement properties of CHROME-G with EuroQol-5 Dimensions-5 Levels (EQ-5D-5L), Short Form-6 Dimensions version 2 (SF-6Dv2), and Diabetes-Specific Quality of Life (DSQL) scales among the elderly Chinese population with type 2 diabetes.
Methods: A representative sample population was recruited across the country.

Background: This study evaluates the health-related quality of life (HRQoL) of persons with diffuse large B-cell lymphoma (DLBCL) by using EQ-5D-5L and SF-6Dv2 and compares the measurement properties of the two instruments.
Method: DLBCL patients were identified via a patient group and were surveyed using web-based questionnaires. Demographic information, socioeconomic status (SES), clinical characteristics, and EQ-5D-5L and SF-6Dv2 responses were collected and statistically described.

The SF-6D health descriptive system and its second version published in 2020, the SF-6Dv2, is used worldwide for valuing health-related quality of life (HRQoL) for economic evaluation and measuring patient-reported health outcomes. In this study, a valuation tool was developed and applied to create a social value set, comprising 18,750 health state values, for the SF-6Dv2 for New Zealand (NZ). This tool was adapted and extended from the one used to create a social value set for the EQ-5D-5L, a simpler health descriptive system with fewer dimensions and health states.
