CBT-I: What It Is and Why It Is First Line
Cognitive behavioural therapy for insomnia is a structured programme delivered by a trained clinician, not something you assemble yourself. van Straten 2017 (meta-analysis, 87 randomised trials) reports it effective in treating insomnia, whether as components or the full package, and Baglioni 2020 (network meta-analysis) reports that none of the interventions it compared were “superior to CBT-I”.
Sleep restriction, a core CBT-I component, is not something to attempt unsupervised.
- Difficulty falling or staying asleep at least three nights a week for three months or more: see a clinician or sleep specialist for CBT-I
- Daytime sleepiness severe enough to affect driving or safety: see a clinician promptly
- Loud snoring with witnessed pauses in breathing: see a clinician, for possible sleep apnoea, which CBT-I does not treat
- Insomnia alongside persistent low mood or thoughts of self-harm: see a clinician or mental-health professional; in crisis call or text 988
What the evidence says
The sources on this entry are meta-analyses, systematic reviews, trials and reviews of cognitive behavioural therapy for insomnia (CBT-I), its components and its comparison with medication, with insomnia severity and sleep-diary measures as the main outcomes. van Straten 2017 (meta-analysis, 87 randomised trials, 3724 treated patients and 2579 controls) reports significant effects on insomnia severity (g = 0.98), sleep efficiency (g = 0.71), wake after sleep onset (g = 0.63) and sleep-onset latency (g = 0.57), with the smallest effect on total sleep time (g = 0.16), and concludes that CBT-I, whether components or full package, is effective in treating insomnia. Kim 2016 (meta-analysis, 16 trials, 1503 participants) reports that CBT-I improves both sleep quality and quantity in patients with insomnia, with small to moderate effect sizes, and Okajima 2011 (meta-analysis, 14 randomised trials) reports CBT-I effective for treatment and relapse prevention of primary insomnia despite some publication bias. On durability, Bootzin 2013 reports improvement maintained up to 2 years after treatment ends, whereas insomnia recurs after hypnotics are stopped; Harvey 2012 reports positive effects well sustained for at least one year after treatment ends; Koffel 2015 (meta-analysis, 8 studies) reports group CBT-I effects persisting at 3-12 month follow-up; Davidson 2019 (systematic review, 13 studies) reports medium-to-large effects of CBT-I over 4-6 sessions, generally well maintained 3-12 months post-treatment; and Morin 2015 reports significant, well-sustained improvements in sleep with no adverse outcomes. Against medication, Mitchell 2012 (systematic review, 5 studies) concludes that CBT-I is effective for insomnia compared with medications, with more durable effects, and that providers should consider it as first-line treatment. Jacobs 2004 (randomised trial) reports CBT effective for chronic sleep-onset insomnia and “superior to pharmacotherapy”, with pharmacotherapy producing only moderate improvements that reversed after discontinuation and combined treatment adding no benefit over CBT alone. Rossman 2019 reports that CBT-I produces “results equivalent to sleep medication”, with fewer relapses and continued sleep improvement after treatment ends. Kathol 2016 reports that the ACP recommends CBT-I as first-line treatment and names non-recognition of insomnia and a limited number of trained practitioners among the implementation challenges. Baglioni 2020 (network meta-analysis, 36 studies) reports that none of the interventions it compared were “superior to CBT-I”. On components, Steinmetz 2024 (component network meta-analysis, 80 studies, 15,351 participants) reports a significant effect of sleep restriction therapy on insomnia severity, improved total sleep time with stimulus control, and no significant effects for psychoeducation, relaxation or cognitive therapy, and names sleep restriction and stimulus control “the most effective components of CBT-I”. Maurer 2021 (meta-analysis, 8 randomised trials) reports large effects of sleep restriction therapy on insomnia severity and sleep continuity and no effect on total sleep time, with results limited by few comparisons, high risk of bias and heterogeneity. Verreault 2023 (network meta-analysis, 23 studies) reports stimulus control effective for improving insomnia compared with control conditions, with results to be interpreted cautiously given study quality. Furukawa 2024 (component network meta-analysis, 241 trials) reports that cognitive restructuring, third-wave components, sleep restriction, stimulus control and in-person delivery may be beneficial. Morin 1994 (meta-analysis, 59 studies, 2102 patients) reports psychological treatments effective and durable for chronic insomnia, with sleep hygiene education alone not effective. Rios 2019 (overview of 64 systematic reviews) reports consistent effectiveness across multiple outcomes for CBT alongside several medications, mostly evaluated short-term, with over half of the reviews of low quality. It is a structured programme delivered by a trained clinician, and it is described here so you know what to ask for.
- Misconception: 'Sleeping pills are the main option.' CBT-I matches medication long term and does not relapse on discontinuation.
- Misconception: 'I can do it myself from an article.' Its active components include sleep restriction, which is titrated by a clinician.

Each source below is shown with its study design and a link to the original study, or, where it is not a completed research paper, with what kind of record it is; those are not counted. This is the audit trail.
Why do some records show a record type instead of a study design?
A study design is shown for a completed, peer-reviewed paper. A registered protocol, a preprint, a conference abstract, a referee report or a book chapter has not been through peer review as a finished paper, so it is labelled for what it is, and it is counted in no source count. Where a record could not be confirmed as a completed paper at all, it says so rather than guessing. They all stay in the list, and their DOI still resolves, because the count of what was screened is part of the audit trail.
- Protocol / registration A registered plan for a review or trial, not its results.
- Preprint Posted by its authors before peer review.
- Conference abstract A conference summary rather than a peer-reviewed paper.
- Peer-review report A referee's report on a paper, not the paper itself.
- Guideline / position stand A recommendation derived from evidence, which is a step further from the data than the evidence itself.
- Book chapter A chapter in a scholarly book rather than a journal paper.
- Type not recorded Our record does not say what kind of publication this is, so it is counted in no source count. That is a gap in our data, not a judgement about the research.
