<div class="info-box">
The <strong>Obsessive Compulsive Inventory - Revised (OCI-R)</strong> is a widely used self-report screening instrument designed to assess the severity and frequency of obsessive-compulsive symptoms and related distress.
</div>
<div class="info-box">
The OCI-R was originally developed by <strong>Foa, Huppert, Leiberg, Langner, Kichic, Hajcak, and Salkovskis</strong> in <strong>2002</strong> to provide a brief and clinically effective measure of obsessive-compulsive symptom dimensions.
</div>
<div class="info-box">
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).
</div>
<div class="info-box">
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.
