Note. FTF = face-to-face. CDI = computer delivered interventions. Reported coefficients are unstandardized. Predictors that were significant (mixed-effects models) are in bold. Predictors that remained significant using the adjusted p-values obtained from the permutation tests (5,000 permutations) are indicated by underline.
