Abstract
PURPOSE: Loneliness among the elderly is a widespread phenomenon and is connected to various negative health outcomes. Nevertheless, loneliness among elderly inpatients, especially those with a psychiatric diagnosis, has hardly been examined. Our study assessed loneliness in elderly inpatients, identified predictors, and compared levels of loneliness between inpatients on psychiatric and somatic wards. METHODS: N = 100 elderly inpatients of a somatic and psychiatric ward were included. Levels of loneliness were assessed, as were potential predictors such as depression, psychological resilience, severity of mental illness, well-being, daily functioning, and psychiatric diagnosis. Analyses of group differences and hierarchical multiple regression analysis were conducted. RESULTS: 37% of all inpatients reported elevated levels of loneliness. Significant predictor variables were self-reported depressive symptoms, well-being, severity of mental illness, being single and living with a caregiver. Hierarchical multiple regression analysis revealed that the full model explained 58% of variance in loneliness. Psychiatric inpatients' loneliness was significantly higher than loneliness in somatic inpatients. When analyzing group differences between inpatients with different main psychiatric diagnoses, highest levels were found in patients with an affective disorder, followed by those treated for organic mental disorder. Since the study took place during the COVID-19 pandemic, potential influence of different measurement points (lockdown vs. no lockdown) were analyzed: Differences in loneliness depending on the phase of the pandemic were non-significant. CONCLUSION: Elderly inpatients experience high levels of loneliness, especially those with a mental disorder. Interventions to reduce loneliness in this population should address predictors of loneliness, preferably through multiprofessional interventions.
