Acceptance and commitment-based therapy for patients with psychiatric and physical health conditions in routine general hospital care - Development, implementation and outcomes.

Abstract

OBJECTIVE\nTransdiagnostic approaches are needed to effectively treat patients with a broad range of diagnoses and comorbidities in routine general hospital care. Yet the evidence for the effectiveness of treatments beyond Cognitive Behavioral Therapy (CBT) is largely lacking. We describe the process of implementing an interdisciplinary multi-professional Acceptance and Commitment Therapy (ACT)-based treatment for patients with psychiatric and physical health conditions and present outcomes before and after implementation.\n\n\nMETHOD\nThe present investigation was a naturalistic comparative study comparing ACT-based (n\xa0=\xa0126) vs. CBT-based (n\xa0=\xa0127) treatments in a psychiatric day hospital in Berlin, Germany. Within- and between-group changes (pre- to post-treatment) in everyday functioning and health-related quality of life (primary outcomes; assessed by the Short Form 36 (SF-36)), as well as anxiety and depressive symptoms (secondary outcomes; assessed by the Hospital Anxiety and Depression Scale (HADS) and Beck Depression Inventory-II (BDI-II)), were analyzed with Generalized Linear Models, and Wilcoxon signed-rank tests and effect size r.\n\n\nRESULTS\nData analysis showed statistically significant improvements from pre- to post-treatment (r ranging from 0.27 to 0.61, p\xa0<\xa00.001) for most SF-36 scales as well as for all HADS and BDI-II scores (r ranging from 0.38 to 0.60, p\xa0<\xa00.001) for both the ACT and CBT groups. ACT and CBT showed comparable effects in relation to clinical outcomes.\n\n\nCONCLUSION\nAn interdisciplinary multi-professional ACT-based group treatment is a valuable approach for patients with psychiatric and physical health conditions in real-life hospital settings, with effects equivalent to CBT interventions.
