OCD & Related Disorders

Obsessive-Compulsive and Related Disorders (DSM-5-TR)

This topic groups OCD and related disorders, including body dysmorphic disorder, hoarding, trichotillomania and excoriation. Treatment recommendations differ by diagnosis; the completed assessment below concerns adults with OCD.

Prevalence: ~2.3% lifetime and ~1.2% past year for OCD (NIMH, from NCS-R)

Clinical Picture

For adults with OCD, NICE CG31 recommends CBT that includes exposure and response prevention (ERP), with treatment intensity matched to functional impairment, preferences and response. This page groups related diagnoses for browsing; the adult OCD assessment does not establish the same recommendation for every diagnosis listed here.

Treatment Considerations

NICE CG31 offers low-intensity CBT including ERP for adult OCD when impairment is mild and/or the person prefers a low-intensity approach. For mild impairment when this is unsuitable or inadequate, or for moderate impairment, it offers a choice between an SSRI and more intensive CBT including ERP. For severe impairment, it recommends an SSRI together with CBT including ERP. These recommendations do not establish a preferred treatment for every related disorder, child or adolescent. The guideline was published in 2005 and NICE lists an update in progress.


Approaches and Evidence

Of 6 associated approaches, 1 have completed assessments for this topic, 2 have source checks awaiting assessment, and 3 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

Exposure and Response Prevention

Victor Meyer · 1966

Reviewed population: Adults with obsessive-compulsive disorder receiving CBT that includes exposure and response prevention. This is not an assessment for the full OCD-related-disorders category, including hoarding, trichotillomania or excoriation.

NICE CG31 (2005) recommendations 1.5.1.1–1.5.1.4 explicitly offer CBT including ERP for adult OCD, with intensity matched to impairment and treatment response. For moderate impairment it offers a choice between an SSRI and more intensive CBT including ERP; for severe impairment it recommends their combination. The source uses “offer” wording rather than a separately reported GRADE strength. This supports an ERP-within-CBT guideline assessment for adult OCD, not every related diagnosis, a universal monotherapy claim or the catalogue’s legacy effect-size and response estimates. NICE currently lists an update in progress; the 2005 recommendations remain published and the July 2024 changes were presentational.

Reading This Page

Why are these approaches listed with OCD & Related Disorders?

The catalogue associates 6 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.
