Health literacy, worry about unmet needs for medical care, and psychological well-being among older Chinese adults

Abstract

Aim: This study aims to examine the relationship between older adults' health literacy and their psychological well-being and the role of worry about future unmet needs for medical care in mediating this relationship. Methods: We adopted a sample of 965 older Chinese people aged 60+ (49.74% female) from the 2021 Chinese General Social Survey. A series of structural equation models (SEMs) were performed. Health literacy was measured by three items regarding older people's ability to understand medical professionals, ask them questions, and read medical instructions. A single-item question was adopted to measure participants' worry about unmet needs for future medical care. Psychological well-being was measured by three items regarding emotional problems and depressed or anxious mood in the past 4 weeks. Results: Worry about future unmet needs for medical care mediates the relationship between lack of health literacy and Chinese older people's psychological well-being. The indirect effect accounts for 22.3% of the total effect. The SEM model has a satisfactory model fit (goodness of fit index = 1.000, comparative fit index = 0.999, Tucker-Lewis index = 0.997, root mean square error of approximation = 0.009, standardized root mean square residual = 0.023, chi-square test = 50.96, P = 0.321). Conclusions: The findings of this study underscore the importance of improving communication quality between healthcare providers and older adults. Clinical interventions that promote health literacy and address worries about unmet needs for medical services may benefit older adults. Geriatr Gerontol Int 2024; 24: 202–207.
