Results of the simple slope analysis performed to assess differences between ACT and CBT in changes of the outcomes over time.

Note. The simple slope analyses were performed when the interaction between time and treatment was significant. Values of the coefficients can be interpreted as mean changes from baseline to discharge and from discharge to follow-up across the interventions. Coefficients are unstandardized.
