Obsessive-compulsive inventory and obsessive-compulsive inventory-revised scales: translation into brazilian portuguese and cross-cultural adaptation.

Objective: The present study describes the process of translation into Brazilian Portuguese and the cross-cultural adaptation of the Obsessive-Compulsive Inventory and the Obsessive-Compulsive Inventory-Revised scales. The Obsessive-Compulsive Inventory was developed with the purpose of measuring the intensity of the various symptoms that characterize the obsessive-compulsive disorder, assessing their frequency and the distress they caused during the previous month, as well as estimating the overall severity of the disorder.
