The Vancouver Obsessional Compulsive Inventory (VOCI)

Area of Science:

• Psychological assessment
• Clinical psychology
• Psychopathology

Background:

• The Maudsley Obsessional Compulsive Inventory (MOCI) is a widely used self-report measure for obsessive-compulsive problems.
• The MOCI has limitations and requires updating to capture a broader range of obsessive-compulsive disorder (OCD) features.
• Existing measures may not fully encompass the spectrum of obsessions, compulsions, and associated behaviors in OCD.

Purpose of the Study:

• To develop and validate the Vancouver Obsessional Compulsive Inventory (VOCI) as an updated self-report measure for obsessive-compulsive disorder (OCD).
• To assess a wider range of symptoms including obsessions, compulsions, avoidance behaviors, and relevant personality characteristics.
• To provide a reliable and valid instrument for both research and clinical use in the field of OCD.

Main Methods:

• Revision and development of the Maudsley Obsessional Compulsive Inventory (MOCI) into the Vancouver Obsessional Compulsive Inventory (VOCI).
• Evaluation of the VOCI's reliability and validity across diverse samples.
• Inclusion of participants with OCD, other anxiety disorders, depression, community adults, and students.

Main Results:

• The Vancouver Obsessional Compulsive Inventory (VOCI) demonstrates promising reliability and validity.
• The VOCI effectively measures a broad range of obsessive-compulsive symptoms and related factors.
• The instrument performed well across clinical and non-clinical populations.

Conclusions:

• The Vancouver Obsessional Compulsive Inventory (VOCI) is a valuable new tool for assessing obsessive-compulsive disorder (OCD).
• The VOCI offers a more comprehensive assessment compared to its predecessor, the MOCI.
• The VOCI is expected to be widely adopted in OCD research and clinical practice.
