Digital cognitive behavior therapy for insomnia improving sleep quality: a real-world study

Area of Science:

• Digital Health
• Sleep Medicine
• Psychiatry

Background:

• Digital cognitive behavior therapy for insomnia (dCBT-I) is an established treatment for insomnia.
• This study evaluated dCBT-I's effectiveness in a real-world clinical setting for patients with insomnia complaints.

Purpose of the Study:

• To assess the impact of dCBT-I on sleep quality in a clinical population.
• To compare different dCBT-I treatment modalities and durations.

Main Methods:

• Included 6,002 adult patients with insomnia, anxiety, or comorbid conditions.
• Utilized a mobile app for dCBT-I delivery and self-reported assessments.
• Primary outcome: change in sleep quality (Pittsburgh Sleep Quality Index - PSQI) at 8 and 12 weeks.

Main Results:

• Significant sleep quality improvements observed across all treatment groups by 8 weeks.
• Further significant PSQI score reductions at 12 weeks for depression patients on combined therapy and anxiety patients on dCBT-I monotherapy or combined therapy.
• Time-by-treatment interaction noted in anxiety patients, indicating varied treatment effects over time.

Conclusions:

• dCBT-I is a practical and effective approach for reducing insomnia symptoms.
• An extended intervention period of 12 weeks may be more beneficial for patients with anxiety symptoms.
