Note. Intake BDI-II = intake Beck Depression Inventory-II, Intake BAI = intake Beck Anxiety Inventory, Time = linear slope, Time² = quadratic slope.

Values represent unstandardized betas. The intercept represents estimated depression at week 8. For significant interactions with Time, negative values indicate a prediction of greater overall change. For significant interactions with Time², positive values indicate greater rapid early change.
