  1. Each column represents a multiple linear regression model with one of the WHO-QoL Bref Domains or the BDI as the dependent variable and all 25 THI items as independent variables. *letters represent THI subscales; F: functional, E: emotional, C: catastrophic; R2 (adjusted R2), coefficient of determination (coefficient of determination adjusted for the number of exploratory items); B, regression coefficient, p, p-value; all significant items (p < 0.05) are printed in boldface.
