Effect of WBT for CI With Depression

This randomized controlled trial aims to explore the therapeutic effects of Well-Being Therapy (WBT) on patients with Chronic Insomnia accompanied by depressive symptoms.

According to DSM-IV criteria, approximately 6%-10% of the adult population in industrialized countries suffer from chronic insomnia (CI), characterized by difficulties in initiating or maintaining sleep accompanied by daytime symptoms persisting for at least four weeks. Chronic insomnia often leads to various psychiatric symptoms, with depressive symptoms being among the most common. For patients with CI and comorbid depressive symptoms, the most common treatment involves the use of antidepressant medications. However, while depressive symptoms may improve, insomnia symptoms often persist. Among non-pharmacological interventions aimed at promoting psychological well-being, Well-Being Therapy (WBT) stands out as a brief and innovative psychotherapeutic approach. WBT is a structured, manualized, short-term therapy that incorporates self-monitoring of well-being episodes through the use of a diary, cognitive restructuring of interfering thoughts and behaviors, and homework assignments. Previous research has demonstrated the effectiveness of WBT in alleviating stress in populations experiencing 'allostatic load.' This study seeks to evaluate the therapeutic effects of six WBT sessions on individuals with CI and comorbid depressive symptoms.
