Worried about intrusive thoughts, checking rituals, or contamination fears? The MOCI test (Maudsley Obsessive-Compulsive Inventory) is a classic 30-item self-report used in OCD research and clinical screening. On LuriaLab you can take the free MOCI online with instant scoring.

What Is the MOCI?

Developed by Hodgson and Rachman, the Maudsley Obsessive Compulsive Inventory measures OCD-related symptoms across areas such as checking, cleaning, slowness, and doubting. Higher total scores suggest more OCD-related difficulties on this screen.

MOCI vs OCI-R

  • MOCI — 30 items, widely cited in research
  • OCI-R — shorter 18-item obsessive-compulsive inventory with subscales

Many people take both when exploring obsessive-compulsive symptoms. Neither replaces a clinical OCD assessment.
