Note. Global cognition (composite score = Mini-Mental State Examination + Verbal Fluence (animal category) + Clock Drawing Test + Episodic Memory (name and address)/4); PiL = Purpose in Life; GDS = Geriatric Depression Scale (total score); ρ = Spearman's rho; CI = confidence interval; p-value < 0.05 shows statistical significance.
