General self-efficacy and frailty in hospitalized older patients: The mediating effect of loneliness

This study aimed to explore the relationship between general self-efficacy and frailty in hospitalized older adults with chronic diseases, and to examine the mediating role of loneliness. A total of 327 hospitalized older patients aged 60 years or above with chronic diseases were recruited. Cross-sectional data on the patients' general self-efficacy, frailty and loneliness were collected using questionnaires. The PROCESS macro of the bias correction bootstrapping method was used to test the mediation model. The results showed that the significant mediating role of loneliness between general self-efficacy and frailty (B = -0.735, 95% CI [-0.923, -0.564]) explained 42.4% of the total effect of general self-efficacy on frailty. These findings highlighted the importance of loneliness in older patients with chronic diseases in hospital, especially those with low general self-efficacy.
