 YALE-BROWN OBSESSIVE COMPULSIVE SCALE (Y-BOCS)*


The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS) is a test to rate the severity of obsessive–compulsive disorder (OCD) symptoms.

The scale, which was designed by Wayne K. Goodman and his colleagues, is used extensively in research and clinical practice to both determine severity of OCD and to monitor improvement during treatment.[1] This scale, which measures obsessions separately from compulsions, specifically measures the severity of symptoms of obsessive–compulsive disorder without being biased towards or against the type of content the obsessions or compulsions might present.[2][3] Following the original publication, the total score is usually computed from the subscales for obsessions (items 1–5) and compulsions (items 6–10), but other algorithms exist.[4]



While the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) is a widely used tool for OCD screening, there are several other assessments available to identify OCD symptoms and severity. Below is a list of commonly used OCD screeners.

1. Obsessive-Compulsive Inventory-Revised (OCI-R) DOWNLOAD

- A self-report questionnaire with 18 items that measures the presence and distress associated with OCD symptoms.
- Covers six domains: washing, checking, doubting, obsessing, mental neutralizing, and hoarding.
- Each item is rated on a 5-point Likert scale, making it useful for assessing the severity of OCD symptoms.

2. Florida Obsessive-Compulsive Inventory (FOCI)

- A brief self-report tool with two sections:
  1. Symptom Checklist: Identifies the presence of various OCD symptoms.
  2. Severity Scale: Assesses the severity of symptoms over the past week.
- Provides a quick assessment of OCD symptoms and is often used in both clinical and research settings.

3. Dimensional Obsessive-Compulsive Scale (DOCS) DOWNLOAD

- Consists of 20 items that assess four symptom dimensions of OCD: contamination, responsibility for harm, unacceptable thoughts, and symmetry/completeness.
- Provides a dimensional view of symptom severity and is often used to track progress in treatment.

4. Obsessive Beliefs Questionnaire (OBQ-44) DOWNLOAD

- Focuses on cognitive factors associated with OCD, like perfectionism, responsibility, overestimation of threat, and need for control.
- Contains 44 items and is used to understand the cognitive distortions that contribute to OCD symptoms.

5. Padua Inventory-Washington State University Revision (PI-WSUR)

- A 39-item self-report measure that assesses the presence of various OCD symptoms across five subscales: contamination obsessions, checking, obsessional thoughts of harm, obsessional impulses, and mental compulsions.
- Helps identify the severity and specific areas of OCD symptoms.

6. Vancouver Obsessional Compulsive Inventory (VOCI)

- A self-report measure that evaluates a wide range of OCD symptoms, with 55 items covering dimensions like obsessions, compulsions, contamination fears, checking behaviors, and hoarding.
- Provides a broader assessment of OCD symptoms and can be useful for comprehensive evaluations.

7. Child Yale-Brown Obsessive Compulsive Scale (CY-BOCS)

- A version of the Y-BOCS tailored specifically for children and adolescents, measuring OCD symptom severity across obsessions and compulsions.
- Used to assess OCD in younger populations, helping differentiate OCD from other anxiety disorders in children.

8. Leyton Obsessional Inventory (LOI)

- One of the older measures for OCD, available in both adult and child versions.
- Assesses the frequency and severity of OCD symptoms, as well as the individual's insight into these symptoms.

9. OCD Self-Screening Test (OCD-SST)

- A short self-report screener that provides a quick evaluation of the likelihood of OCD, based on the individual's experiences of obsessions and compulsions.

10. Revised Obsessive-Compulsive Scale (ROCS)

- A short questionnaire designed to evaluate obsessive thoughts and compulsive behaviors, making it suitable for both initial screenings and monitoring progress in therapy.
