Do symptoms of depression, anxiety or stress impair the effectiveness of cognitive behavioural therapy for insomnia? A chart-review of 455 patients with chronic insomnia

摘要

Background: Co-occurring insomnia and symptoms of depression, anxiety, and stress pose difficult diagnostic and treatment decisions for clinicians. Cognitive Behavioural Therapy for Insomnia (CBTi) is the recommended first-line insomnia treatment, however symptoms of depression, anxiety and stress may reduce the effectiveness of CBTi. We examined the effect of low, moderate, and severe symptoms of depression, anxiety, and stress on insomnia improvements during CBTi.
