The mediating effect of eHealth literacy on the relationship between health personality and quality of life in community-dwelling older adults.

ABSTRACT

AIMS: To explore the relationship between health personality and quality of life among community-dwelling older adults and to examine the mediating effect of eHealth literacy on this relationship. METHODS: A total of 413 community-dwelling older adults from central China were recruited from September 2022 to January 2023. A cross-sectional investigation was conducted using the Chinese versions of the Health Personality Assessment (HPA), eHealth Literacy Scale (eHEALS), and 12-item Short Form Health Survey (SF-12). Correlations between the three variables were examined by Pearson analysis, and mediation analysis was conducted to explore the direct, indirect, and total effects of the health personality on quality of life vis-à-vis eHealth literacy. RESULTS: Health personality factors (including health neuroticism, health openness, and health conscientiousness), eHealth literacy, and quality of life are significantly correlated (P<0.05); eHealth literacy can play a significant mediating role in the relationship between health neuroticism (ß= -0.256, 95 %CI [-0.405, -0.119]), health openness (ß = 0.488, 95 % CI [0.343,0.652]), health conscientiousness (ß= 0.489, 95 % CI [0.354, 0.634]) and quality of life. CONCLUSION: This study revealed that the effect of health personality factors (including health neuroticism, health openness, and health conscientiousness) on quality of life in older adults was mediated through eHealth literacy. IMPACT Individual personality is essential to understanding eHealth literacy and quality of life among community-dwelling older adults. It may be helpful to identify the health personality traits of older adults first, then implement targeted interventions accordingly to enhance eHealth literacy and ultimately improve quality of life.
