The Validation of a New Obsessive-Compulsive Disorder Scale: The Obsessive-Compulsive Inventory

The Obsessive-Compulsive Inventory (OCI) is a new self-report instrument developed to address the problems inherent in available instruments for determining the diagnosis and severity of obsessive-compulsive disorder (OCD).

description The Obsessive-Compulsive Inventory (OCI) is a new self-report instrument developed to address the problems inherent in available instruments for determining the diagnosis and severity of obsessive-compulsive disorder (OCD). The OCI consists of 42 items composing 7 subscales: Washing, Checking, Doubting, Ordering, Obsessing (i.e., having obsessional thoughts), Hoarding, and Mental Neutralizing. Each item is rated on a 5-point (0-4) Likert scale of symptom frequency and associated distress. One hundred and forty-seven individuals diagnosed with OCD; 58 with generalized social phobia; 44 with posttraumatic stress disorder; and 194 nonpatients completed the OCI and other measures of OCD, anxiety, and depression. The present article describes the psychometrics of the OCI including (a) scale construction and content validity, (b) reliability (internal consistency and retest reliability), and (c) convergent and discriminant validity. The OCI exhibited satisfactory reliability and validity with all 4 samples.
