Views on Ageing and Loneliness in Older Patients Undergoing Geriatric Treatment

Background/Objectives: Loneliness is a clinically relevant psychosocial factor in later life and has been associated with adverse mental, cognitive, and physical health outcomes. Views on ageing may shape social engagement, coping, and perceived belonging, but evidence from geriatric patient populations remains limited. This study examined whether views on ageing are associated with loneliness in geriatric patients. Secondary analyses explored subjective age, including felt age and the perceived onset of old age. Methods: This cross-sectional analysis used baseline data from two prospective observational studies in geriatric patients (N = 459). Loneliness was assessed with the three-item UCLA Loneliness Scale. Views on ageing were measured using five items from the German Ageing Survey. Associations were examined using Spearman correlations, non-parametric group comparisons, and multiple linear regression. Results: Participants had a mean age of 83.1 years and 65.6% were female. The mean UCLA loneliness score was 1.54 ± 2.07, and the mean views on ageing sum score was 13.21 ± 2.72. More negative views on ageing were associated with higher loneliness (ρ = 0.122, p = 0.009). In the fully adjusted regression model, views on ageing remained independently associated with loneliness after adjustment for chronological age, sex, and depressive symptoms (β = 0.117, p = 0.014; adjusted R² = 0.051). Depressive symptoms were also independently associated with loneliness (β = 0.182, p < 0.001), whereas chronological age and sex were not. At the item level, associations with loneliness were mainly driven by reduced positive ageing-related beliefs. Higher felt age was associated with higher loneliness (ρ = 0.151, p = 0.003), while a later perceived onset of old age was associated with lower loneliness (ρ = -0.136, p = 0.017). Conclusions: In geriatric patients, more negative views on ageing were weakly associated with higher loneliness independent of depressive symptoms. The small effect size suggests that views on ageing should be interpreted as one modest component within a broader biopsychosocial understanding of loneliness in geriatric care.
