The effect of positive mental well-being on patient reported outcome (PRO): finding from a cross-sectional multi-disease study in China.

Purpose: This study aims to investigate the potential impact of positive mental well-being on responses of patient-reported outcome measures (PROMs), such as EQ-5D-5L. Methods: This study utilized the data collected in a cross-sectional study in a sample consisted of individuals with different health conditions. Spearman's rank correlations were employed to investigate the relationship between the responses to the dimensions of EQ-5D-5L and the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS). A binary logistic regression analysis and ordered logistic multivariable regression were utilized to examine how SWEMWBS scores could impact the responses to EQ-5D-5L dimensions, while controlling for variables such as age, gender, education level, health conditions, caring experience, and data collection methods. The effects of SWEMWBS on EQ-VAS and utility values were also examined. Results: One thousand nine individuals participated in the survey. Spearman's rank correlation revealed that all dimensions of EQ-5D-5L, except for the anxiety/depression dimension, exhibited weak correlations with all dimensions of SWEMWBS. Binary logistic regression and ordered logistic multivariable regression indicated that age, SWEMWBS scores, gender, health conditions, data collection methods, and caring experience significantly influenced the likelihood of reporting problems in EQ-5D-5L responses. Notably, better SWEMWBS outcomes increased the likelihood of reporting no or fewer problems across all EQ-5D-5L dimensions. Spearman's rank correlation suggested a moderate or strong positive correlation between SWEMWBS scores and EQ-5D-5L utility values and EQ-VAS. The results of multiple linear regression analysis revealed that SWEMWBS scores, health conditions, caring experience, and data collection methods were significantly associated with EQ-5D utility values and EQ-VAS. Conclusions: Individuals with better positive mental well-being results are more likely to report better results in PROMs like EQ-5D-5L. Future study is needed to understand the thought process and to explore strategies to cope with the response heterogeneity that led by the status of mental well-being. [ABSTRACT FROM AUTHOR]
