What is the Obsessional Compulsive Inventory-Revised (OCI-R)?
The Obsessional Compulsive Inventory-Revised (OCI-R) is a widely used self-reporting psychological assessment tool designed to evaluate the severity and presence of symptoms associated with Obsessive-Compulsive Disorder (OCD). This inventory, which is an updated version of the original Obsessional Compulsive Inventory, comprises 18 items that participants respond to based on their experiences over the past month. The responses are rated on a 5-point Likert scale ranging from 0 ("not at all") to 4 ("extremely").
The OCI-R, which assesses OCD and hoarding disorder, is structured around six subscales, each reflecting a specific dimension of OCD symptoms:
- Washing
- Checking
- Ordering
- Obsessing
- Hoarding
- Neutralizing
Each subscale consists of three items, making the inventory concise yet comprehensive as it measures OCD symptoms, along with more severe hoarding symptoms. This structure allows clinicians and researchers to assess not only the overall severity of OCD but also specific symptom dimensions, which can guide targeted therapeutic interventions.
The revised version, developed by Edna Foa and her colleagues, is favored for its brevity, reliability, and validity, making it an efficient tool for clinical settings and research studies. It helps in the diagnosis, assessment, and monitoring of treatment progress in individuals with OCD. The OCI-R has been validated in various populations and has been translated into several languages, supporting its applicability in diverse cultural contexts.
