The Obsessive-Compulsive Inventory (OCI) was developed to help determine the severity of obsessive-
compulsive disorder (OCD). The scale is copyright and is reproduced here with the permission of the
authors.
The OCI consists of 42 items composing 7 subscales: Washing, Checking, Doubting, Ordering, Obsessing
(i.e. having obsessional thoughts), Hoarding, and Mental Neutralising. Each item is rated on a 5-point (0-
4) scale of symptom distress.
Mean scores are calculated for each of the seven subscales, and an overall mean ‘distress’ score is
provided (rounded to 2 decimal places). Each score is presented as a mean out of a possible maximum
of ‘4’. Lower scores are better. A total score of 42 or more, or a mean score of 2.5 or more in any of the
subscales suggests the presence of OCD, but is not diagnostic.
