What was done
An American Academy of Sleep Medicine task force reviewed the evidence on nonpharmacological treatments for primary chronic insomnia, evaluating 48 clinical trials and two meta-analyses to establish clinical practice parameters and classify interventions against American Psychological Association efficacy criteria.
What was found
Nonpharmacological interventions benefited 70% to 80% of treated patients. For typical primary insomnia, treatment reduced sleep onset latency and/or wake after sleep onset to near or below 30 minutes, increased total sleep duration by approximately 30 minutes, and significantly improved sleep quality and satisfaction. Gains were sustained for at least 6 months post-treatment. However, there was no clear evidence of meaningful improvements in daytime well-being or performance. Stimulus control, progressive muscle relaxation, and paradoxical intention met criteria for empirically supported treatments, while sleep restriction, biofeedback, and multifaceted cognitive-behavior therapy met criteria for probably efficacious treatments.
Why it matters
This review establishes non-drug modalities as reliable, durable first-line options for improving sleep continuity and duration in primary insomnia, identifying which specific behavioral techniques have the strongest empirical backing.
Limits
The review focused primarily on primary insomnia, leaving effectiveness in patients with medical or psychiatric comorbidities unaddressed. Total participant sample size is not stated in the abstract. Evidence was insufficient to demonstrate benefits on daytime functioning or performance, and effectiveness when delivered by non-sleep specialists in primary care settings remains unverified.
