ICD-10 Obsessive-Compulsive Disorder: Diagnostic Criteria and Clinical Insights
Introduction to ICD-10 and OCD
Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by persistent, unwanted thoughts (obsessions) and repetitive behaviors (compulsions). The International Classification of Diseases, 10th Edition (ICD-10), provides a standardized framework for diagnosing OCD, which has been widely used in clinical settings globally.
Diagnostic Criteria and Subcategories in ICD-10
Definition and Symptomatology
ICD-10 defines OCD by the presence of obsessions and/or compulsions that are time-consuming and cause significant distress or impairment. Obsessions are intrusive thoughts, images, or urges, while compulsions are repetitive behaviors or mental acts performed to reduce anxiety3. The ICD-10 categorizes OCD into three subtypes: predominantly obsessional thoughts (F42.0), predominantly compulsive acts (F42.1), and mixed obsessional thoughts and acts (F42.2)4.
Clinical Utility and Limitations
Research has shown that the ICD-10 subcategories may not adequately differentiate between patients with predominantly obsessive or compulsive symptoms. Quantitative assessments, such as the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), have been suggested as more effective tools for clinical differentiation4. Additionally, the ICD-10's requirement for symptoms to persist for at least two weeks has been criticized, with recommendations to remove this duration criterion in the upcoming ICD-113.
Prevalence and Comorbidity
Epidemiological Insights
A study analyzing data from the British National Psychiatric Morbidity Survey of 2000 found that the one-month prevalence of OCD was 1.1% among adults in Great Britain. The study also highlighted significant comorbidity with other neurotic disorders, such as depressive episodes, generalized anxiety disorder, and various phobias5. This high comorbidity underscores the complexity of OCD and the need for comprehensive diagnostic criteria.
Impact on Quality of Life
OCD significantly impacts patients' quality of life, often more severely than other mental health conditions like schizophrenia. Patients with OCD report lower scores in psychological well-being and social relationships compared to the general population and even those with schizophrenia8. This highlights the profound effect of OCD on daily functioning and the importance of effective treatment strategies.
Transition to ICD-11
Proposed Changes and Improvements
The transition from ICD-10 to ICD-11 aims to address several limitations of the current diagnostic guidelines. Key proposed changes include clarifying the definitions of obsessions and compulsions, removing the two-week duration requirement, and introducing a specifier for insight levels3. These modifications are intended to enhance the scientific validity, clinical utility, and global applicability of OCD diagnostic guidelines.
New Grouping: Obsessive-Compulsive and Related Disorders (OCRD)
ICD-11 introduces a new grouping called Obsessive-Compulsive and Related Disorders (OCRD), which includes OCD, body dysmorphic disorder, hoarding disorder, trichotillomania, and skin-picking disorder, among others. This reclassification aligns with the DSM-5 and aims to improve diagnostic accuracy and treatment outcomes by recognizing the shared characteristics of these disorders1 9.
Conclusion
The ICD-10 provides a foundational framework for diagnosing OCD, but it has notable limitations that the upcoming ICD-11 seeks to address. By refining diagnostic criteria and introducing a new OCRD grouping, ICD-11 aims to enhance the accuracy and clinical utility of OCD diagnoses, ultimately improving patient outcomes. Understanding these changes is crucial for clinicians and researchers working to better identify and treat OCD and related disorders.

Accuracy of diagnostic judgments using ICD-11 vs. ICD-10 diagnostic guidelines for obsessive-compulsive and related disorders.
ICD-11 guidelines resulted in more accurate diagnosis of obsessive-compulsive and related disorders compared to ICD-10 guidelines, particularly in differentiating presentations from one another.

Large Human Trial
Rigorous JournalDSM-IV field trial: obsessive-compulsive disorder.
The DSM-IV should de-emphasize insight requirements and include mental rituals in the definition of compulsions, as patients with obsessive-compulsive disorder have a broad range of insight.

Modifications to the ICD-10 diagnostic guidelines for OCD are recommended for ICD-11, including clarifying the definition of obsessions and compulsions, removing the duration requirement, and allowing diagnosis if comorbid with Tourette syndrome, schizophrenia, or depressive disorders.

ICD-10 subcategories for obsessive-compulsive disorder may be inadequate for distinguishing between predominantly obsessive and compulsive patients, suggesting the importance of quantitative assessment in clinical settings.
