Purpose: This study aims to evaluate anxiety, depression, loneliness, death anxiety, and quality of life and investigate their relationship with social frailty in the geriatric population. Additionally, it aimed to identify social frailty predictors.Methods: The study included 136 participants admitted to the geriatric outpatient clinic. The 15-item Geriatric Depression Scale (GDS-15), the Multidimensional Scale of Perceived Social Support (MSPSS), the Cumulative Illness Rating Scale for Geriatrics (CIRS-G), the Templer Death Anxiety Scale (T-DAS), the Loneliness Scale for the Elderly (LSE), the Quality of Life Scale (CASP-19), the Generalized Anxiety Disorder-7 Test (GAD-7), the Tilburg Frailty Indicator (TFI), the FRAIL Scale, and the Clinical Frailty Scale (CFS) were performed.The TFI was used to collect data about social frailty.Results: There were 61.8 % females, and the median age (min-max) was 72.2 (65.3-90.3) years. The prevalence rate of social frailty was 26.7%. The rates of depression, loneliness, anxiety, death anxiety, the burden of chronic disease, and frailty were higher in the social frailty group. Furthermore, logistic regression analysis revealed a strong relationship between social frailty status and being widowed (odds ratio (OR), 6.86; 95% con dence interval (95% CI), 2.42-19.37; p<0.001), having moderate to severe anxiety symptoms (OR, 4.37; 95% CI,; p = 0.038), and a TFI-physical frailty score (OR, 1.40; 95% CI, 1.12-1.73; p = 0.002).Conclusion: As a result, the social dimension of frailty affects older adults' quality of life and psychological state. Physical frailty and sociodemographic characteristics (being widowed) predict the development of social frailty.
