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.
