Note. Statistical significance: *** p < 0.001. PHQ-9 = Patient Health Questionnaire-9; WAI-TECH-SF = Working Alliance Inventory applied to Internet–Short Form. R = Multiple Correlation Coefficient; R² = Coefficient of determination; R² Change = Coefficient of determination Change; B = Unstandardized coefficient; SE = Standard Error; β = Beta coefficient; t = t statistic (estimated coefficient divided by its own SE).
