Abstract:
Objective:To investigate the correlation between psychological resilience and the risk of all-cause mortality in disabled older individuals.Methods:A total of 8, 089 disabled older adults were selected from the Chinese Longitudinal Healthy Longevity Survey(1998-2018)after screening with the Katz index.Psychological resilience was assessed at baseline using a seven-item self-rating scale.Participants were followed up until 2018, with survival data being recorded.Restricted cubic spline regression and Cox proportional hazard models were employed to analyze the association between psychological resilience and all-cause mortality, as well as to explore the potential interaction between psychological resilience and levels of disability.Results:After adjusting for potential confounding factors, a linearly negative relationship was found between levels of psychological resilience and mortality risk( P-nonlinear 0.781).Stratified analyses by degree of disability revealed that for older adults with mild disability, a 1 standard deviation increase in psychological resilience was associated with a 12% decrease in mortality risk( HR=0.88, 95% CI: 0.83-0.94).However, no significant association was observed between psychological resilience and mortality risk in severely disabled participants.A significant interaction was noted between resilience levels and degree of disability( P-interaction=0.026). Conclusions:This study offers observational evidence supporting the importance of maintaining psychological resilience in reducing mortality risk among disabled older individuals, particularly those with mild disability.The findings highlight the potential benefits of psychological interventions for older adults with varying levels of functional decline.
