Obsessive Compulsive Inventory - Revised (OCI-R)

Background

The Obsessive Compulsive Inventory - Revised (OCI-R) is a widely used self-report screening instrument designed to assess the severity and frequency of obsessive-compulsive symptoms and related distress.
The OCI-R was originally developed by Foa, Huppert, Leiberg, Langner, Kichic, Hajcak, and Salkovskis in 2002 to provide a brief and clinically effective measure of obsessive-compulsive symptom dimensions.
The questionnaire evaluates obsessive thoughts, compulsive behaviors, checking rituals, contamination fears, ordering behaviors, hoarding tendencies, mental obsessions, and counting compulsions commonly associated with obsessive-compulsive disorder (OCD).
Research studies have demonstrated strong validity, reliability, and clinical usefulness for the OCI-R across mental health clinics, psychological assessment settings, healthcare environments, and research populations. The scale is commonly used to screen obsessive-compulsive symptom severity and monitor treatment progress.

Psychological Domains Measured

Hoarding
Measures difficulty discarding items, excessive saving behaviors, attachment to possessions, and clutter-related distress.
Checking
Measures repeated checking behaviors, reassurance-seeking, and compulsive monitoring of safety-related concerns.
Ordering
Measures distress related to symmetry, organization, arrangement, and the need for things to feel “just right.”
Counting
Measures repetitive counting rituals, number-related compulsions, and beliefs about specific numbers.
Washing and Contamination
Measures contamination fears, excessive washing, cleaning rituals, and discomfort related to germs or contact with others.
Obsessions and Intrusive Thoughts
Measures unwanted intrusive thoughts, mental compulsions, distressing images, and difficulty controlling repetitive thoughts.
The OCI-R is commonly used in psychology, psychiatry, healthcare, counseling, and research settings. The questionnaire is intended as a screening instrument and should not be used as a standalone diagnostic tool.

Procedure

This questionnaire is designed to be completed by adults and adolescents based on their recent thoughts, compulsive behaviors, emotional experiences, and repetitive mental or behavioral patterns.

Participants select the response option that best describes how much each symptom or behavior has distressed or bothered them during recent functioning.

The assessment focuses on obsessive thoughts, compulsive rituals, checking behaviors, contamination fears, ordering needs, counting compulsions, and hoarding tendencies.

Participation

This assessment is intended for educational, screening, and research purposes only.

Results should not be considered a clinical diagnosis or substitute for professional psychological, psychiatric, or medical evaluation.

Individuals experiencing severe obsessive thoughts, compulsive rituals, emotional distress, anxiety, or major impairment in daily functioning are strongly encouraged to seek support from a qualified mental health professional.

Scoring & Interpretation

Responses are scored on a 0–4 scale according to symptom severity and emotional distress.

Higher scores generally indicate stronger obsessive-compulsive symptoms, compulsive rituals, intrusive thoughts, contamination fears, hoarding behaviors, and psychological distress.

The OCI-R contains six primary symptom dimensions:
- Hoarding
- Checking
- Ordering
- Counting
- Washing
- Obsessing

The OCI-R is commonly used as a screening tool to help identify individuals who may benefit from additional psychological or psychiatric evaluation.
