Multi-level structural equation mediation models of depressive symptoms on visuospatial functions through apathy. Standardized coefficients are reported. For simplicity, baseline age, gender, and education covariates are not depicted. Dep Sx = depressive symptoms; Visuospatial = visuospatial functions (assessed via Judgment of Line Orientation); Motor Sx = Motor symptoms. Model fit: chi-square = 800.31, df = 333, p < 0.001; Root Mean Square Error of Approximation [RMSEA] = 0.05; Comparative Fit Index [CFI] = 0.94; Normed Fit Index [NFI] = 0.90.
