Abstract

Objective: To examine the association between vision-related quality of life (VRQoL) and depressive symptoms in residents with vision impairment (VI) in aged care facilities.Methods: In this cross-sectional study using baseline data from a cluster-randomized controlled trial (ACTRN12615000587505) assessing the effectiveness of a novel eye care model, 186 English-speaking residents (mean age 84 years, SD[standard deviation] = 8.7; 33.9% male) with VI and moderate cognitive functioning or better were recruited from 38 facilities across Victoria, Australia. VRQoL was measured using Rasch-transformed scores from the 'Reading'; 'Mobility', and 'Emotional' scales of the Impact of Vision Impairment for Residential Care (IVI-RC) questionnaire. Outcomes were presence of depressive symptoms (binary score: Cornell Scale for Depression in Dementia [CSDD] > 0 vs. CSDD = 0) and severity of depressive symptoms (continuous CSDD score; sample range 1-21). Independent associations with presence and severity of depressive symptoms were examined using zero-inflated logistic and linear multivariable models, respectively.Results: Of the 186 participants, n = 79 (42.5%), n = 94 (50.5%) and n = 13 (7%) reported no, mild (scores 1-7), and clinically significant depressive symptoms (score ≥8), respectively. Better vision-related Mobility (OR = 0.64; 95% CI: 0.44, 0.95, p = 0.02) was associated with reduced odds of depressive symptoms. With every unit improvement in vision-related Reading (β=-0.48; 95% CI: -0.94, -0.01, p = 0.04) and Emotional (β=-0.56; 95% CI: -1.09, -0.02, p = 0.04), severity of depressive symptoms reduced, independent of sociodemographic and medical issues.Conclusion: Better VRQoL was independently associated with reduced depressive symptoms. Supporting older people in aged care to maintain optimal levels of vision-specific functioning, independence, and emotional well-being may protect their mental health.
