Why it matters

Digital CBT-I is a scalable, low-intensity intervention for insomnia, but optimal dosing has been unclear. This analysis provides clinicians with evidence-based guidance on treatment duration, suggesting that 250-minute protocols may maximize benefit while avoiding unnecessary length. The differential sensitivity in comorbid insomnia highlights the need for tailored approaches in patients with co-occurring conditions.
