Associations with smartphone usage and life satisfaction among older adults: Mediating roles of depressive symptoms and cognitive function

This study aimed to investigate the serial mediating effects of depressive symptoms and cognitive function on the relationship between smartphone usage and life satisfaction among older people. Multiple linear regression analyses for complex randomly sampled data were used to identify the association between the status/level of smartphone usage, depressive symptoms, cognitive function, and life satisfaction. Further-more, the Sobel test was conducted to assess the serial mediating effects of depressive symptoms and cogni-tive function on the relationship between smartphone usage and life satisfaction. The status and level of smartphone usage had significant positive impacts on cognitive function and life satisfaction, and negative impacts on depressive symptoms. Our results suggest that nurses should assess the status and level of smart -phone usage among older people and plan approaches that enable them to utilize various smartphone functions to improve the well-being of this population.(c) 2023 Elsevier Inc.
