Adherence
Higher baseline depression scores are associated with poorer treatment outcomes in CBT for insomnia, indicating that psychological distress may reduce the efficacy of sleep-focused therapy.
If you are struggling with both insomnia and depression, be open with your therapist. Your sleep treatment may be less effective if your depression is not addressed. Integrating mental health support with CBT may improve your sleep outcomes.
GoodQualifiesHIGH confidence
Multiple regression analyses of PSQI scores within the sleep clinic group alone indicated that the magnitude of pre- to post-treatment change in overall sleep quality was closely related to Hospital Anxiety and Depression Scale depression scores at 3-, 6-and 12-month follow-ups. In each model higher depression scores at baseline were associated with poorer treatment outcomes.
