Note. Coefficients are unstandardized. The fixed effects “Time T0-T1” and “Time T1-T2” indicate change in the outcomes from baseline to discharge and from discharge to follow-up, irrespectively of intervention. The fixed effect “Intervention” indicates differences between the ACT and CBT interventions, irrespectively of time. The interaction terms “Time T0–T1*Intervention” and “Time T1–T2*Intervention” indicate changes over time of the outcomes due to having received the ACT or the CBT intervention. Abbreviations: ACT: Acceptance and Commitment Therapy; CBT: Cognitive Behavioral Therapy; ED: CORE-wellbeing: Clinical Outcome in Routine Evaluation-Wellbeing; CORE-symptoms: Clinical Outcome in Routine Evaluation-Symptoms/Problems; CORE-functioning: Clinical Outcome in Routine Evaluation-Functioning; CORE-risk: Clinical Outcome in Routine Evaluation-Risk; AAQ-II: Acceptance and Action Questionnaire-II. * Significant effect. ^a Estimates based on a zero-inflated Poisson model with a log link function.
