The Florida Obsessive-Compulsive Inventory (FOCI) is a 25-item self-report questionnaire that is used to measure the presence of and severity of obsessive-compulsive symptoms.
The FOCI is divided into a Symptom Checklist (Part A) and a Severity Scale (Part B). In the instance that at least one symptom is endorsed in the Symptom Checklist, the individual then rates the severity of the endorsed symptom(s) in the Severity Scale according to five areas: time occupied, interference, distress, resistance, and degree of control. These items are summed to provide a Severity Scale score. Higher scores on the Severity Scale correspond with greater symptom severity. Higher scores on the Symptom Checklist correspond with presence of numerically more symptoms.

The FOCI was developed by Wayne K. Goodman, MD, Esther and Joseph Klingenstein Professor and Chair of Psychiatry at the Mount Sinai School of Medicine.
