Final Structural Equation Model (SEM) of Relationships between Dimensions of Disability. Goodness of Fit Statistics: Comparative Fit Indices (CFI): 1.00; Tucker Lewis Index (TLI): 0.993; Root Mean Square of Error of Approximation (RMSEA): 0.04. Numbers indicate standardized path coefficients; the magnitude of the relationship (Range is 0–1); Solid lines indicate direct effect; Dashed lines indicate non-significant relationship; Curved lines indicate correlations. Bolded path coefficients indicate strong (> 0.50) predictive relationships; Green arrows indicate strongest mediating relationship. *Example Interpretation: An increase in uncertainty 1 standard deviation above the mean predicts a 0.53 standard deviation increase above the mean in mental-emotional health challenges (while controlling for physical, cognitive, and social challenges)
