Description:

Purpose		The VOCI was designed to provide a self-report assessment of a range of obsessions, compulsions, avoidance behavior, and personality characteristics of known or theoretical importance in obsessive–compulsive disorder (OCD). It is a development of the MOCI scale.
Questions		55 items using a five-point Likert-type scale
Sub-scales		6 sub-scales: Contaminations (12 items) Checking (6 items) Obsessions (12 items) Hoarding (7 items) Just right (12 items) Indecisiveness (6 items)
Domain		Clinical
Psychometrics
Sample items		I feel compelled to check letters over and over before mailing them. I become very tense or upset when I think about throwing anything away. I am strongly compelled to count things. I worry far too much that I might upset other people.
