• Behavioral and psychological treatments for chronic insomnia disorder in adults

  American Academy of Sleep Medicine · 2021-02-01; JCSM 17(2):255–262; DOI 10.5664/jcsm.8986 · Clinical guideline · Recommendation 1; Methods

  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 2026-09-06

• 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

  Source checked 2026-09-06

• Management of chronic insomnia disorder in adults

  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.

  Scope: Adults with chronic insomnia disorder

  Source checked 2026-09-06

• Daridorexant for treating long-term insomnia (TA922)

  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

  Source checked 2026-09-06

• Management of Chronic Insomnia Disorder and Obstructive Sleep Apnea

  US Department of Veterans Affairs / Department of Defense · Version 3.0; January 2025; evidence through 2024-03-31; current PDF filename dated 2025-09-15 · Clinical guideline · Recommendations 5 and 8; Table 4, p.34

  Recommendation for the stated population

  VA/DoD strongly recommends CBT-I and weakly favors CBT-I over medication initially. These recommendations address insomnia, not treatment of its comorbid diagnoses.

  Scope: Adults with chronic insomnia disorder; initial treatment selection.

Insomnia & Sleep Disorders

Population and scope: 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.

Guideline recommendation

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.

• Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder

  VA/DoD · 2023 · Clinical guideline · Recommendation 33, page 81

  Insufficient evidence for or against

  VA/DoD finds insufficient evidence for or against IRT for nightmares associated with PTSD.

  Scope: Nightmares associated with PTSD

• Position paper for the treatment of nightmare disorder in adults

  American Academy of Sleep Medicine · 2018; JCSM 14(6):1041–1055; DOI 10.5664/jcsm.7178 · Professional reference · Position statements: behavioral and psychological options

  Recommendation for the stated population

  AASM recommends IRT for these nightmare presentations. It calls this a position paper, not a graded CPG.

  Insufficient evidence for or against

  APA finds insufficient evidence for or against IRT for adult PTSD relative to no intervention or treatment as usual. This is a different scope from AASM’s nightmare-specific position.

PTSD & Acute Trauma

Population and scope: Adults with PTSD-associated nightmares.

Guideline evidence inconclusive

VA/DoD 2023 recommendation 33 is inconclusive. AASM’s 2018 position paper recommends IRT for nightmares; it is not a graded CPG or a recommendation for all PTSD symptoms.

CBT-I

Core mechanism: Sleep restriction and stimulus control consolidate sleep drive and decondition wakefulness; cognitive restructuring reduces hyperarousal and catastrophic thinking about sleep

Ontology: Chronic insomnia as a learned disorder of hyperarousal and conditioned sleeplessness maintained by maladaptive behaviors and beliefs, not a primary neurological deficit

Imagery Rehearsal Therapy

Core mechanism: Cognitive rescripting of nightmare content combined with imagery rehearsal changes nightmare frequency and distress through mechanisms likely involving memory reconsolidation and reduced conditioned fear

Ontology: Nightmares as a learned maladaptive sleep behavior that can be directly targeted and modified through intentional cognitive and imaginal intervention

CBT-I

Philosophical roots: Behavioral learning theory (Pavlov, Skinner); cognitive appraisal theory; Spielman's 3P model (predisposing, precipitating, perpetuating factors)

Blind spots: Sleep restriction can be challenging for people with bipolar disorder (may trigger mania); requires motivation and tolerance of short-term worsening; group or digital formats may not address comorbidities

Therapeutic voice: We're going to compress the time you spend in bed to build up your sleep drive. It will feel harder before it feels easier.

Imagery Rehearsal Therapy

Philosophical roots: Behavioral learning theory; cognitive appraisal; Lang's bio-informational theory of emotional imagery (emotional processing theory proper is Foa and Kozak's later extension of it); sleep science

Blind spots: Requires willingness to engage with nightmare content; some find rescripting counterintuitive; not suitable during acute destabilization; limited training infrastructure

Therapeutic voice: Pick any part of the nightmare and change it however you want. It doesn't have to make sense, and it doesn't have to be the ending. Then we'll rehearse the new version until it's the one that comes easily.
