Hierarchical multiple regression analyses predicting number of treatment sessions attended for FFT.

Full model: R = .48, adjusted R² = .14

Note. sr² = squared semipartial correlation coefficient, indicating the unique variance accounted for by the variable at that point in the equation (ΔR²), F(sr) = test for reliable contribution of the variable [F (ΔR²)]; R² = squared multiple regression coefficient, indicating the total variance in the criterion variable accounted for by the predictor variable in the regression equation at that point; B = multiple regression coefficient; β = standardized multiple regression coefficient.
