Multivariable ROC Analysisa for the Index Screening Instruments and their Short Forms for Current Major Depression Disorder (N = 179b).

* pa Adjusted multivariable non-parametric ROC analyses were also performed (Jane H., et al., 2009) because some covariates may affect the accuracy of the instruments. Bivariate analysis was first performed to examine the crude association between the ROC curve of each instrument and each covariate. Covariates generally entered into the final multivariable model if p-value b Of 190 patients, 179 provided demographic, psychosocial and behavioural information.c Coefficients of adjusted multivariable model generally reflect impacts of a specific covariate on the adjusted ROC curve by assuming a linear relationship (Jane H., et al., 2009).d Receipt of Ontario Disability Support Program (ODSP) subsidies was used as a proxy measure for physical or mental disabilityMultivariable ROC Analysisa for the Index Screening Instruments and their Short Forms for Current Major Depression Disorder (N = 179b).
