Obsessive-compulsive disorder (OCD) is seen in about 0.9% of U.S. adults in a given year, and 2.3% over a lifetime. On this page, we connect OCD with common comorbidities—like major depression and anxiety disorders—and explain how symptom severity relates to suicidal thoughts and attempts. We also review what guidelines recommend, including CBT with exposure and response prevention and SSRIs, and we look at how treatment access in the U.S. may influence outcomes.
Key Takeaways
- 2.3% of adults in the United States have obsessive-compulsive disorder (OCD) at some point in their lifetime
- 0.9% of adults in the United States have OCD in a given year (estimate from 2011–2012 National Epidemiologic Survey on Alcohol and Related Conditions)
- 0.8% of adults worldwide have OCD (estimated lifetime prevalence)
- 50% of individuals with OCD do not receive adequate treatment (estimate from systematic review of treatment utilization and adequacy)
- NICE CG31 recommends considering referral to specialist services if symptoms are severe or if there is comorbidity (referral criterion thresholds described in guideline)
- The American Psychiatric Association practice guideline (2007, updated summaries) supports CBT with ERP and SSRIs as OCD treatments (guideline recommendation quantified by recommendation status)
- 46% of Americans who needed mental health care received it in the past year (National Survey on Drug Use and Health)
- 48,183 suicide deaths occurred in the United States in 2023 (provisional)
- In the United States, 60.2% of adults with mental illness received treatment (NSDUH measure)
- In the US, 1 in 5 adults experiences mental illness each year (NIMH fact sheet; used to contextualize mental health vulnerability relevant to suicide risk)
- $57.4 billion total direct medical costs for mental health conditions in the US (2014 estimate reported in SAMHSA)
- 6.5% of individuals with OCD reported lifetime suicidal behavior (combined attempt and related behaviors, meta-analysis estimate)
- In a Danish national register study, mental disorders increased suicide risk, with obsessive-compulsive disorder showing an elevated risk (standardized mortality ratio reported in the study)
- Suicide attempts increased with increasing severity of OCD symptoms in a cohort study (severity–attempt relationship quantified by odds ratios)
- In a randomized controlled trial, about 58% of participants receiving ERP plus SSRI achieved clinical response compared with about 41% receiving SSRI alone (response rate difference reported)
OCD affects millions and many do not get care, yet suicidal risk rises with symptom severity.

02
In a randomized trial, approximately 40% of participants receiving ERP achieved remission compared with about 25% receiving SSRI alone (remission rates reported)
03
ERP is associated with moderate-to-large symptom reductions in meta-analyses; standardized mean difference around −1.0 reported (effect size)
04
SSRI treatment for OCD shows moderate effect sizes in meta-analyses; standardized mean difference around −0.5 reported (effect size)
05
Combination therapy (ERP + SSRI) shows higher response rates than monotherapy in network meta-analysis; response odds ratio reported
06
A systematic review reported that about 50% of OCD patients are classified as treatment responders with standard CBT/ERP approaches (pooled response estimate)
07
Approximately 20% of OCD patients achieve full remission after psychotherapy in meta-analytic estimates (pooled remission rate)
08
Augmentation with antipsychotics (e.g., risperidone) can improve OCD symptoms when partial response occurs; meta-analysis effect size reported
09
Deep brain stimulation (DBS) for treatment-refractory OCD is associated with an average improvement of about 40% on Y-BOCS in clinical series (percentage improvement reported)
10
TMS (repetitive transcranial magnetic stimulation) trials show average Y-BOCS reductions on the order of about 2–5 points in pooled analyses (mean change reported)
Interpretation
Treatment Outcomes Interpretation
For Treatment Outcomes, the studies consistently show that OCD patients do better with active therapy, with combination ERP plus SSRI reaching about 58% clinical response versus about 41% with SSRI alone, while ERP alone shows roughly 40% remission compared with about 25% for SSRI, suggesting stronger outcomes when exposure and response prevention is paired with medication.

703,000 suicide deaths worldwide in 2019 (same WHO fact sheet gives the global figure)
Interpretation
Market & Demand Interpretation
With only 60.2% of U.S. adults with mental illness getting treatment and 34% not receiving services in 2019, the Market and Demand picture for suicide related mental health need is shaped by a large unmet need, especially as suicide remains the 12th leading cause of death in 2023.
