Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Generalised anxiety disorder and panic disorder in adults (CG113)
Discussed in the source
CBT-based written or electronic self-help is specified, with trained-practitioner support for guided programmes. This supports a delivery category, not every app.
Scope: Adults with GAD offered step 2 self-help
- Depression in adults: treatment and management (NG222)
Discussed in the source
NICE includes supported printed or digital structured self-help, including CBT. The programme and support requirements matter.
Scope: Adults with depression choosing guided self-help
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against facilitated internet-based CBT for PTSD. Validated video-delivered therapies have a different recommendation.
Scope: Facilitated internet-based CBT for adults with PTSD.
- Assessment and Management of Patients at Risk for Suicide
Discussed in the source
VA/DoD weakly supports this digital-intervention category for short-term ideation, but finds insufficient evidence for reducing attempts or suicide. This does not endorse every CBT app.
Scope: Adults aged 18 and over at risk of suicide; self-guided digital interventions containing CBT-based content; short-term suicidal-ideation outcomes.
- Management of Major Depressive Disorder
Recommendation for the stated population
VA/DoD suggests clinician-guided computer/internet CBT as first-line treatment or alongside medication, according to preference (weak for). This does not endorse every app or unguided programme.
Scope: Adults with mild-to-moderate MDD; clinician-guided delivery.
- Management of Bipolar Disorder
Discussed in the source
VA/DoD finds insufficient evidence for any particular app or computer/web intervention. This broader technology finding is not a specific assessment of every iCBT programme.
Scope: Adults with bipolar disorder; digital interventions.
- Clinical Practice Guideline for the Management of Substance Use Disorders
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against these treatments. Its review includes CBT4CBT and distinguishes computerized treatment from live therapist telemedicine and text-message support.
Scope: Computer-delivered CBT and other behavioral treatments for substance-use disorders, alone or alongside usual care.
- Clinical Practice Guideline for the Management of Chronic Multisymptom Illness
Discussed in the source
VA/DoD discusses internet delivery under its broader CBT recommendation. It does not separately grade internet CBT or establish that all delivery formats are equivalent for every patient.
Scope: Internet-delivered CBT studied in ME/CFS within the chronic multisymptom illness guideline.
- Tinnitus
Discussed in the source
The CBT discussion includes internet delivery with provider involvement. It finds insufficient evidence for completely self-administered CBT without therapist contact; this is not an endorsement of every app.
Scope: Internet-delivered CBT with provider involvement for adults with bothersome tinnitus.
- Clinical Practice Guideline for Management of Stroke Rehabilitation
Discussed in the source
The guideline discusses computerized CBT under its broader weak recommendation for psychotherapy after stroke. It does not separately establish a preferred digital program or equivalence of all delivery formats.
Scope: Computerized CBT studied for depression following stroke.
- mhGAP: delivery format of brief structured psychological interventions
Discussed in the source
WHO conditionally recommends considering digital and other CBT delivery formats according to resources and preferences, with low-certainty evidence. This does not separately grade every internet program or establish equal suitability for every person.
Scope: Adults receiving brief CBT-based interventions for GAD/panic
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
The review includes internet CBT. WHO notes that guided internet CBT was more effective than unguided delivery for this population; its clinical recommendation is for structured psychological interventions, rather than every digital program.
Scope: Adults with moderate-to-severe depression, within the mhGAP non-specialist-care context.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
Digital or remote trauma-focused CBT is included in the conditional recommendation, based on low-certainty evidence. This is a format-and-treatment-class recommendation, not an endorsement of every internet CBT program.
Scope: Adults with PTSD.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
WHO conditionally supports digital interventions based on approaches including CBT, with low-certainty evidence. This is not a recommendation for every full CBT program, and the reviewed trials did not establish benefit for attempts or deaths and were underpowered for those outcomes.
Scope: Digital support for people with suicidal thoughts.

Depression & Mood Disorders
Population and scope: Adults with mild-to-moderate MDD receiving clinician-guided internet CBT.
Guideline recommendation
VA/DoD 2022 recommendation 10 weakly supports clinician-guided computer/internet CBT as initial treatment or alongside medication, according to preference. It does not extend to unguided apps or establish equivalence to in-person therapy.
Source assessment dated
Anxiety Disorders
Population and scope: Adults with GAD or social anxiety disorder using the specific supported internet-delivered CBT programs studied; iCBT here is a delivery format, not inference-based CBT.
Randomized studies
A GAD trial randomized 150 people to clinician-assisted or technician-assisted online CBT or delayed treatment; 145 were analyzed, and both supported programs improved outcomes versus delay. A separate 126-person social-anxiety trial found therapist-supported internet CBT noninferior to group CBT within its prespecified margin through six months. These findings concern particular supported programs and diagnoses, not every app, unguided use, or equivalence to all face-to-face CBT. GAD follow-up attrition and the social-anxiety trial's permissive noninferiority margin limit interpretation.

Guidelines and official sources (10)
9 clinical guideline checks · 1 evidence registry check
Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Depression in adults: treatment and management (NG222)
Recommendation for the stated population
NICE includes problem-solving among treatment options. The format and choice depend on depression severity, clinical needs and patient preferences.
Scope: Adults with depression; guided self-help or individual problem-solving options.
- Problem-Solving Therapy for Depression
Discussed in the source
The archive records a 1998 strong rating and a 2015 status awaiting re-evaluation. These are evidence-registry classifications, separate from NICE’s recommendations.
Scope: Depression; historical Division 12 treatment ratings.
- Assessment and Management of Patients at Risk for Suicide
Recommendation for the stated population
VA/DoD includes problem-solving-based psychotherapies within its weak recommendation for suicide-focused CBT to reduce suicidal ideation. This recommendation concerns ideation and does not establish fewer suicide attempts or deaths for generic PST.
Scope: Suicide-focused, problem-solving-based CBT for adults aged 18 and over with a history of self-directed violence.
- Management of Major Depressive Disorder
Recommendation for the stated population
VA/DoD suggests problem-solving therapy among seven unranked psychotherapy options (weak for). Treatment strategy also depends on severity, chronicity, prior response and preference.
Scope: Adults with uncomplicated MDD choosing psychotherapy.
- Management of Major Depressive Disorder
Discussed in the source
VA/DoD strongly recommends first-line evidence-based psychotherapy, referring to the list that includes problem-solving therapy. This is a class-level recommendation, with no preferred individual approach.
Scope: Pregnant or breastfeeding adults with mild-to-moderate MDD.
- Clinical Practice Guideline for Management of Stroke Rehabilitation
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against solution-focused psychological interventions, explicitly including problem-solving therapy. The finding is specific to post-stroke depression prevention.
Scope: Preventing the onset of depression following stroke.
- Clinical Practice Guideline for the Treatment of Depression Across Three Age Cohorts
Recommendation for the stated population
APA conditionally suggests the specified individual problem-solving treatments for these populations.
Scope: Older adults with MDD and executive dysfunction, or minor/MDD depression with dementia.
- mhGAP: brief structured psychological treatment for depression
Recommendation for the stated population
WHO includes problem-solving therapy among the structured psychological interventions that should be offered. The recommendation is strong, with moderate-certainty evidence.
Scope: Adults with moderate-to-severe depression, within the mhGAP non-specialist-care context.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
WHO conditionally supports digital interventions based on approaches including problem-solving therapy, with low-certainty evidence. This is not a recommendation for every full problem-solving therapy program, and the reviewed trials did not establish benefit for attempts or deaths and were underpowered for those outcomes.
Scope: Digital support for people with suicidal thoughts.
- Self-harm: assessment, management and preventing recurrence (NG225)
Recommendation for the stated population
NICE says to offer a tailored intervention and explicitly names CBT and problem-solving therapy. This does not endorse every generic protocol or establish a reduction in suicide deaths.
Scope: Adults who have self-harmed; a structured, person-centred CBT-informed intervention tailored to their needs.

Suicidality & Self-Harm
Population and scope: Adults who self-harm receiving a tailored CBT-informed problem-solving intervention; suicide-focused problem-solving therapy for adults with a history of self-directed violence.
Guideline recommendation
NICE NG225 1.11.3 explicitly includes problem-solving therapy within its offered CBT-informed intervention tailored to adults who self-harm. VA/DoD 2024 recommendation 6 weakly suggests suicide-focused CBT, including problem-solving-based therapies, to reduce ideation after self-directed violence. The scope is a tailored or suicide-focused intervention, not every generic PST programme. The VA recommendation concerns ideation and does not establish fewer suicide attempts or deaths for generic PST.
Source assessment dated
Depression & Mood Disorders
Population and scope: Adults with uncomplicated MDD choosing psychotherapy.
Guideline recommendation
VA/DoD 2022 recommendation 7 weakly suggests PST among unranked options. This treatment recommendation does not establish superior efficacy or address depression prevention across other clinical populations.

How they work
iCBT
Core mechanism: Same cognitive and behavioral mechanisms as face-to-face CBT (restructuring distorted cognitions and modifying avoidance) delivered via digital platform
Ontology: Same as CBT (dysfunctional cognitions and avoidance maintaining distress) with the added assumption that therapeutic content can be transmitted and practiced effectively in digital form
Problem-Solving Therapy
Core mechanism: Structured problem-solving skills (define, generate, evaluate, implement) counteract hopelessness and behavioral inaction in depression
Ontology: Depression maintained by poor problem orientation (negative appraisal of problems) and deficient problem-solving skills

What each assumes — and misses
iCBT
Philosophical roots: CBT's philosophical foundations, plus a pragmatist assumption worth naming rather than burying: that the medium is a neutral pipe, and that what CBT does can be separated from the presence of another person doing it
Blind spots: Dropout higher than face-to-face; may not adequately address relational or trauma dimensions; requires digital access and literacy; variable therapist involvement across programs creates inconsistency in outcomes
Therapeutic voice: This week's module is on identifying automatic thoughts. Complete the thought record on the platform and we'll review it in our messaging check-in.
Problem-Solving Therapy
Philosophical roots: Dewey (reflective problem-solving); cognitive-behavioral tradition; D'Zurilla (social problem-solving model); pragmatism
Blind spots: Structured skill focus can leave emotional and relational material untouched; later versions add emotion-focused coping for problems that cannot be solved, but the frame still fits situational difficulty better than grief or existential impasse
Therapeutic voice: Let's list every possible solution, even the ones that seem impractical. We'll evaluate them after.
Choosing between them
iCBT and Problem-Solving Therapy 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.
