N2 - The study aimed to investigate the mediating effect of fatigue and the moderating effect of sleep quality on stress and depressive symptoms among people with visual impairments. A total of 155 participants completed the online survey. The Perceived Stress Scale, the Fatigue Symptom Inventory, the Centre for Epidemiological Studies-Depression Inventory (CES-D), and the Pittsburgh Sleep Quality Index (PSQI) were used. Descriptive analysis, correlations, and moderated mediation modelling were conducted using R software. From the mediator variable (FSI) model (F = 22.427, R2 = 56.5, p <.001) and the dependent variable (CES-D) model (F = 35.912, R2 = 70.5, p <.001), after controlling for age, sex, employment, and education, sleep quality positively predicted fatigue levels (β = 2.422, p =.009), and fatigue positively predicted depressive symptoms (β =.152, p <.001). Sleep quality is an essential component of psychological well-being in people with visual impairments.
