- 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
- Combination treatment for chronic insomnia disorder in adults
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
- Management of chronic insomnia disorder in adults
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
- Daridorexant for treating long-term insomnia (TA922)
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
- Management of Chronic Insomnia Disorder and Obstructive Sleep Apnea
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.

Anxiety Disorders
Population and scope: Adults with co-occurring clinically elevated insomnia and anxiety symptoms, selected using ISI and GAD-7 thresholds, receiving a supported four-lesson internet CBT-I program.
Randomized studies
Mason et al. (2023) randomized 120 adults to internet CBT-I or internet CBT for anxiety. Both groups reported reduced anxiety; GAD-7 improvement did not differ significantly between groups through three-month follow-up. CBT-I improved insomnia more at post-treatment, but that sleep advantage did not persist significantly at follow-up. The active-comparator study does not establish equivalence, anxiety-diagnosis remission, or effects in anxiety without insomnia. Entry used symptom thresholds, and diagnostic interviews were not repeated after treatment. This scoped randomized-study label does not borrow the separate insomnia guideline recommendation.

Depression & Mood Disorders
Population and scope: Adults aged 18–75 with both major depressive disorder and insomnia, receiving antidepressant pharmacotherapy in the 150-person TRIAD trial.
Randomized studies
Manber et al. (2016) compared seven-session CBT-I with a credible insomnia control therapy, both added to antidepressant treatment, over 16 weeks. The primary time-to-depression-remission outcome did not differ significantly; neither did depression symptom improvement. Insomnia improved more with CBT-I. Secondary analyses linked early sleep improvement with subsequent depression remission, but do not overturn the null primary comparison. Recruitment was below target. This evaluates an adjunct for comorbid insomnia and depression, not standalone depression treatment or depression without insomnia.

- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Recommendation for the stated population
PE is one of three specifically named strongly recommended trauma-focused psychotherapies.
Scope: Adults with PTSD
- Post-traumatic stress disorder (NG116)
Recommendation for the stated population
NICE explicitly includes PE among trauma-focused CBT interventions.
Scope: Adults with clinically important PTSD symptoms; timing and diagnosis determine the recommendation
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends PE as a first-line adult PTSD treatment compared with no intervention or treatment as usual.
Scope: Adults with PTSD; comparison with no intervention or treatment as usual
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Discussed in the source
VA/DoD suggests co-occurring disorders should not preclude these PTSD treatments. This addresses access to treatment, not a separate claim of treating substance use.
Scope: PTSD with co-occurring substance-use disorder or other disorders; therapies named in recommendations 8 and 9.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Insufficient evidence for or against
APA finds insufficient evidence to prefer PE over those comparators. Its recommendation versus no treatment or usual care does not establish superiority over active therapy.
Scope: Adults with PTSD; PE versus the other active psychological treatments listed in the table.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends this combination; the table includes PE plus usual care and the COPE protocol.
Scope: Adults with PTSD and co-occurring SUD; PE-based treatment plus usual SUD care versus usual SUD care alone.
- mhGAP evidence profile STR1/STR2: PTSD psychological interventions
Discussed in the source
The WHO evidence review includes PE within individual trauma-focused CBT. The clinical recommendation is for that class, not a separately graded PE recommendation.

PTSD & Acute Trauma
Population and scope: Adults with PTSD receiving individual, manualized Prolonged Exposure (PE). This assessment does not grade all acute post-trauma symptoms, prevention after exposure, childhood PTSD or every adaptation of the protocol.
Guideline recommendation
VA/DoD 2023 recommendation 8 strongly recommends individual, manualized PE for adult PTSD. The American Psychological Association’s 2025 guideline also strongly recommends PE compared with no intervention or usual care (printed p. 7). NICE NG116 (2018) recommendation 1.6.16 names it among individual trauma-focused CBT options after more than one month. These recommendations do not establish that PE is superior to every active psychotherapy or validate the catalogue’s legacy response rates.

How they work
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
Prolonged Exposure
Core mechanism: Repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information
Ontology: Fear structure with pathological associations; avoidance prevents emotional processing

What each assumes — and misses
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.
Prolonged Exposure
Philosophical roots: Foa & Kozak (emotional processing theory); Lang (fear structure); Craske (inhibitory learning update); empiricist tradition
Blind spots: Assess practical safety, support and barriers to engagement, and adapt care accordingly. NICE NG116 recommendation 1.7.2 says drug or alcohol misuse alone should not exclude someone with PTSD from treatment. Recommendation 1.7.1 usually prioritizes PTSD treatment when depression co-occurs, but prioritizes depression when its severity prevents PTSD therapy or there is a risk of harm to self or others. Recommendation 1.7.3 calls for support with engagement barriers and attention to safety and stability. The protocol's attention to relational and meaning dimensions remains a clinical consideration, not a finding assessed here.
Therapeutic voice: I want you to close your eyes and tell me what happened, in the present tense, as if it's happening right now.
Choosing between them
CBT-I and Prolonged Exposure both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
