Personality and Health-Related Quality of Life of Older Chinese Adults: A Cross-Sectional Study and Moderated Mediation Model
ABSTRACT
Background:
Personality has an impact on the health-related quality of life (HRQoL) of older adults. However, the relationship and mechanisms of the two variables are controversial, and few studies have been conducted in older adults.
Objective:
The aim of this study was to explore the relationship between personality and HRQoL and the mediating and moderating roles of sleep quality and place of residence in this relationship.
Methods:
A total of 4123 older adults aged 60 years and above were from psychology and behavior investigation of Chinese residents (PBICR). Participants were asked to complete the Big Five Inventory (BFI-10), the Brief version of the Pittsburgh Sleep Quality Index (B-PSQI) and the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L). A back propagation neural network (BPNN) was used to explore the order of factors contributing to HRQoL. Path analysis was performed to evaluate the mediation hypothesis.
Results:
Neuroticism and extraversion were strong influencing factors of HRQoL (normalized importance > 50%). The results of the mediation analysis indicated that the relationship between the two variables was mediated by sleep quality and moderated by place of residence.
Conclusions:
This study sheds light on the potential mechanisms of personality and HRQoL among older Chinese adults and can help health care providers and relevant departments take reasonable measures to promote healthy ageing.
