Abstract:
Objective:To explore the mediating effects of psychological flexibility and exercise self-efficacy between frailty and social isolation among elderly patients with type 2 diabetes mellitus (T2DM), so as to provide the basis for alleviating social isolation in this population.
Methods:From July to November 2024, elderly patients with T2DM aged ≥65 years were selected by using the convenience sampling method from the endocrinology and geriatrics departments of a tertiary hospital in Shanxi Province. Demographic and clinical data were collected using structured questionnaires. Frailty was assessed using the FRAIL Scale, psychological flexibility was measured with the Acceptance and Action Questionnaire-II (AAQ-II), exercise self-efficacy was evaluated via the Chinese version of the Exercise Self-Efficacy Scale, and social isolation was quantified employing the General Alienation Scale. The mediating effects of psychological flexibility and exercise self-efficacy between frailty and social isolation were analyzed using the Process macro program.
Results:A total of 300 elderly patients with T2DM were included, with a mean age of (71.16±4.88) years. There are 167 males (55.67%) and 133 females (44.33%). The mean scores for frailty, psychological flexibility, exercise self-efficacy, and social isolation were (2.82±1.59), (28.32±6.95), (5.69±1.20), and (39.27±9.24). Mediation analysis revealed that frailty positively affected social isolation (β=0.227, 95%CI: 0.132-0.323). It also indirectly positively influenced social isolation through psychological flexibility (β=0.165, 95%CI: 0.105-0.234) and exercise self-efficacy (β=0.150, 95%CI: 0.093-0.217), and the chained mediating effect of psychological flexibility and exercise self-efficacy (β=0.066, 95%CI: 0.038-0.100).
Conclusion:Frailty exacerbates social isolation by diminishing psychological flexibility and exercise self-efficacy among elderly patients with T2DM.
