Fig. 2: Correlations between loneliness, cognitive performance, and depressive symptoms.

Scatterplots illustrate the correlations between UCLA Loneliness Scale scores and performance across a range of cognitive tests as well as scores on the Geriatric Depression Scale. Trend lines with 95% confidence intervals (shaded areas) are included for visual reference. Higher loneliness scores were generally correlated with poorer cognitive performance and greater depressive symptoms. **p < 0.01; *p < 0.05.
