The Florida Obsessive‐Compulsive Inventory (FOCI) is a new self‐report questionnaire that has separate scales for symptom enumeration (The Checklist) and evaluation of symptom severity (Severity Scale). The present research investigated the FOCI in a sample of 113 patients with obsessive‐compulsive disorder (OCD). The results indicated that the FOCI Severity Scale is internally consistent (α = .89) and highly correlated with the total score from the Yale–Brown Obsessive‐Compulsive Scale (Y‐BOCS; Goodman et al., 1989a). The correlations of the FOCI Severity Scale with measures of depression and global severity of psychopathology were similar to those obtained with the Y‐BOCS Total Severity Score. The FOCI Symptom Checklist had adequate reliability (K‐R 20 = .83) and moderate correlations ( r s < .45) with the FOCI Severity Scale, the Y‐BOCS scales, and measures of depression and severity of psychopathology. These findings imply concurrent validity for the FOCI Severity Scale. A strength of the FOCI is that it offers a quick evaluation of both presence and severity of OCD symptoms. An important limitation is that the FOCI does not assess the severity of individual symptoms. © 2007 Wiley Periodicals, Inc. J Clin Psychol 63: 851–859, 2007.
