A clinical effectiveness trial comparing ACT and CBT for inpatients with depressive and mixed mental disorders.

AbstractObjective: Meta-analyses show that Acceptance and Commitment Therapy (ACT) is an efficacious treatment for a wide range of mental health problems. However, few studies have examined the effectiveness of ACT in naturalistic inpatient settings and in direct comparison to Cognitive Behavior Therapy (CBT). The aim of this study was to investigate the effectiveness of ACT and CBT with regard to depression, general symptom strain and life satisfaction. Method: 177 inpatients in a psychiatric ward were included in the study and assigned to either ACT or CBT group intervention. All patients were assessed with the SCID-I interview and disorder-specific questionnaires as well as with a satisfaction with life scale. To control for confounding variables, amongst others, treatment integrity was evaluated. Results: Both the ACT and CBT intervention showed a large, statistically significant and stable symptom reduction over six months across all outcomes. Both approaches led to small improvement in life satisfaction. With regards to depressive symptoms, more than half of the patients reliably recovered due to therapy. Conclusion: ACT and CBT were similarly effective in treating patients with depressive and other mental disorders in a routine clinical setting. ACT is a viable alternative to CBT for treating inpatients.

Diagnosing autism in a clinical sample of adults with intellectual disabilities: how useful are the ADOS and the ADI-R?

Intellectual disability (ID) and autism spectrum disorder (ASD) are frequently co-occurring conditions. Carefully diagnosing ASD in individuals with ID would allow for more tailored clinical interventions that would improve mental health and quality of life. In this study, we evaluated the psychometric properties of the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R) in a clinical sample of 79 adults with ID who were suspected of also having ASD. In the testable cases (68%), the ADOS was over-inclusive (specificity 45%) but highly sensitive (100%) of ASD. In the ADI-R, the feasibility was 37%, with a sensitivity of 88% and a specificity of 80%. Previously proposed adaptations of the ADOS algorithm were evaluated, and new items and tasks were suggested. The ADOS and the ADI-R were found to be valuable diagnostic tools for adults with ID. Adjustments of the setting and the tasks may further improve their feasibility and specificity.
