Obsessive Compulsive Disorder (OCD) subtypes in prepubertal children is an understudied research area. The Obsessive Compulsive Inventory-Child Version (OCI-CV) is a recently developed self-report tool, which, differently from other existing measures, assesses OCD subtypes in 8 to17-year-old children and adolescents. However, studies have examined the psychometric properties of the OCICV in mixed groups composed of children and adolescents, but no study has used only child groups, although the clinical features of OCD in children are different compared to those in adolescents. This study investigated factor structure, reliability, concurrent/divergent validity and the incremental and predictive validity of the Italian OCI-CV in a large non-clinical group of 8 to 11-year-old children. Exploratory and confirmatory factor analyses showed a three-factor structure without 7 of the original items: Pure Obsessions, Washing/Neutralising, Hoarding/Ordering. Scores on the OCI-CV Washing/ Neutralising were moderately correlated with measures of OCD and panic/agoraphobia characteristics and weakly with other anxious aspects and depression. Scores on OCI-CV Pure Obsessions moderately correlated with measures of depression and anxiety except for physical injury anxiety, whereas scores on OCI-CV moderately correlated only with OCD characteristics. Higher scores on the OCI-CV Washing/Neutralising at T0 (β = 0,10, t = 2,56, p < 0,05) but not scores on the OCI-CV Pure Obsessions and OCI-CV Hoarding/Ordering, predicted higher scores on the SCAS OCD at one-year follow up. Differently from previous studies, the Italian version of the OCI-CV showed adequate psychometric properties with a three-factor instead of six-factor structure, without seven items.
