Note: SOFAS, Social and Occupational Functioning Scale. Table entries are unadjusted Pearson correlations and unstandardized multiple regression coefficients ± standard errors. The fourth column summarizes the simultaneous multiple regression analysis. The final column is the Pearson correlation of the DAR total score with the functional measures.
