Adding Acceptance and Commitment Therapy (ACT) to standard inpatient care for depression and insomnia may improve symptoms more than usual care alone. Eight psychiatric inpatients received eight ACT sessions alongside cognitive behavioral therapy and medication. Depressive symptoms, insomnia, psychological flexibility, acceptance of sleep problems, and quality of life all improved significantly from before treatment to one week and three months after treatment. No significant changes occurred during the baseline period before ACT began. The findings suggest ACT is a promising transdiagnostic adjunct for inpatients, but results are preliminary due to the small sample and lack of a control group.
