Cognitive Behavioral Therapy for Insomnia
Introduction to CBT-I
- The American College of Physicians (2016) provides a strong recommendation that all patients with chronic insomnia receive CBT-I as the initial treatment intervention, based on moderate-quality evidence 1
- The American Academy of Sleep Medicine (2017, 2021) designates psychological and behavioral interventions, particularly CBT-I, as the standard of care for chronic insomnia in adults of all ages 2, 3, 4
Evidence of Efficacy
- CBT-I produces clinically meaningful improvements that are sustained for up to 2 years, unlike pharmacotherapy which shows degradation of benefit after discontinuation 2, 5
Why Other Options Are Incorrect
- Polysomnography is not indicated as a first-line diagnostic test for chronic insomnia with a clear clinical presentation 4
- Ferritin level is only relevant if restless legs syndrome is suspected, which is not described in this case 5
- Melatonin has insufficient evidence to determine efficacy for chronic insomnia 2
- Oral hypnotic treatment should only be considered after CBT-I has been tried or when CBT-I is unavailable, using shared decision-making 1, 2
Practical Implementation
- In-person, therapist-led programs are most beneficial, and digital CBT-I is an effective and scalable alternative when in-person therapy is unavailable 3
- Treatment typically requires 4-8 sessions over 6 weeks 3
Common Pitfalls to Avoid
- Do not prescribe hypnotics as first-line treatment, as this violates guideline recommendations and deprives patients of more effective, durable therapy 1, 2
- Do not rely on sleep hygiene education alone, as it lacks efficacy as a single intervention 3, 4
- Do not expect immediate results, as patients need counseling that improvements are gradual but sustained 3
