Insomnia & Sleep Disorders

Sleep-Wake Disorders (DSM-5-TR)

Persistent difficulty initiating or maintaining sleep, early morning awakening, or nonrestorative sleep that impairs daytime functioning. Includes insomnia disorder, circadian rhythm disorders, and sleep disturbances secondary to anxiety, depression, PTSD, or chronic pain. One of the most common complaints in primary care and therapy.

Prevalence: ~30-35% of adults report insomnia symptoms; ~10% meet criteria for chronic insomnia disorder, with published estimates running from 6% to 15% depending on how strictly daytime impairment is required

Clinical Picture

Insomnia is one of the most common clinical presentations and one of the most undertreated, often overshadowed by the conditions it co-occurs with (depression, anxiety, PTSD, chronic pain). CBT for Insomnia (CBT-I) is one of the most effective psychological treatments for any condition, with large effect sizes and durable gains, yet most therapists don't know how to deliver it. The mechanism is primarily behavioral: sleep restriction and stimulus control break the conditioned arousal that maintains insomnia, while cognitive components address the catastrophic thinking about sleeplessness that perpetuates the cycle.

Treatment Considerations

CBT-I is the clear first-line treatment, recommended over medication by the American College of Physicians. It typically requires 4-8 sessions and can be delivered in person, via telehealth, or through guided digital programs. Before starting the sleep restriction component, screen for obstructive sleep apnea, which can masquerade as insomnia and worsens under restriction, and use restriction cautiously or not at all with bipolar disorder, where sleep loss can precipitate mania, and with seizure disorders, where sleep deprivation lowers the threshold. Warn clients that the first weeks bring real daytime sleepiness, which matters if they drive or operate machinery. For insomnia co-occurring with other conditions, treating the insomnia directly (rather than assuming it will resolve when the 'primary' condition improves) often produces better outcomes for both. Mindfulness-based approaches and ACT adaptations for insomnia are showing promise as alternatives or adjuncts. Sleep difficulties in PTSD may require trauma-specific interventions (e.g., Imagery Rehearsal Therapy for nightmares).


Approaches and Evidence

Of 5 associated approaches, 1 have completed assessments for this topic, 0 have source checks awaiting assessment, and 4 have neither recorded yet. Each completed assessment states its population and rationale; source checks alone do not establish effectiveness. These categories describe different findings and review stages; they are not a ranking of treatments.

Guideline recommendation (1)

These assessments record a guideline recommendation for the stated population. Read the scope and rationale; a broad topic label does not make a recommendation applicable to everyone.

Cognitive-Behavioral

Cognitive Behavioral Therapy for Insomnia

Bootzin / Spielman / Morin / Perlis · 1987

Reviewed population: Adults with chronic insomnia disorder receiving multicomponent CBT-I. This assessment concerns insomnia, including when it co-occurs with another condition; it does not grade treatment of obstructive sleep apnea, circadian disorders or the co-occurring diagnosis itself.

AASM’s 2021 recommendation 1 and VA/DoD’s 2025 recommendation 5 strongly recommend multicomponent CBT-I for adult chronic insomnia. VA/DoD recommendation 8 only weakly favors CBT-I over medication as initial treatment. AASM’s 2026 combination guideline conditionally favors CBT-I alone over starting CBT-I and medication together, with low-certainty evidence and preference-based exceptions. The guideline label therefore applies to the defined insomnia treatment, not sleep hygiene alone, every digital program, every sleep disorder or universal superiority to medication.

  • Behavioral and psychological treatments for chronic insomnia disorder in adults

    Recommendation for the stated population

    AASM strongly recommends multicomponent CBT-I. Its 2021 review did not directly compare psychotherapy with medication.

    Scope: Adults with chronic insomnia disorder, with or without comorbidities

    Source checked

  • Combination treatment for chronic insomnia disorder in adults

    American Academy of Sleep Medicine · 2026-04-13; JCSM 22:56; evidence through June 2025 · Clinical guideline · Recommendations 1 and 2; Remark

    Recommendation for the stated population

    AASM conditionally favors CBT-I plus medication over medication alone, and CBT-I alone over the combination; both use low-certainty evidence and allow preference-based exceptions.

    Scope: Adults with chronic insomnia; concurrent initiation of medication and CBT-I

    American College of Physicians · 2016-05-03; Annals of Internal Medicine 165(2) · Clinical guideline · Recommendations 1 and 2

    Recommendation for the stated population

    ACP recommends CBT-I initially; after an unsuccessful course, it suggests shared decisions about adding short-term medication.

    NICE · 2023-10-18 · Clinical guideline · Recommendation 1.1 and rationale

    Discussed in the source

    NICE describes CBT-I as the standard first treatment; daridorexant eligibility requires CBT-I to have failed, be unavailable or be unsuitable. This is a drug technology appraisal, so identify that context.

    Scope: Adults with long-term insomnia being considered for daridorexant

Reading This Page

Why are these approaches listed with Insomnia & Sleep Disorders?

The catalogue associates 5 approaches and 0 frameworks with this topic. These links support learning and comparison; association alone is not a treatment recommendation or evidence of effectiveness.

How should I read the evidence assessments?

Assessments are specific to the population and scope stated on each card. They include a rationale, source links, and a review date. An overall review of an approach does not automatically apply to this condition, and a randomized-study label does not by itself mean that a study found benefit.

What does "Assessment not yet completed" mean?

A condition-specific assessment has not been recorded. Approaches with checked sources appear in a separate assessment-pending group; a checked source can support, oppose, or discuss an intervention without recommending it. Neither pending group means that no research exists or that the approach is ineffective. Frameworks are shown separately.


Sources and Review Scope

Source links and dates on assessment cards apply to the stated population and rationale. The clinical overview and prevalence text above are separate authored content; an approach's evidence label does not verify those statements. Recorded narrative notes and citations remain available on individual modality pages, with their review status identified. The bibliography provides further reading.
