Psychometric properties of the Short Leyton Obsessional Inventory-Child Version in a community sample of Spanish children and adolescents

The aim of the current study was to analyze psychometric properties of the Short LOI-CV in Spanish community sample. Participants were 914 children and adolescents with a mean age of 13.01 years (51.3% males). The EFA yielded a three-factor model representing Obsessions, Compulsions, and Cleanliness dimensions. Both, total score and subscales showed an adequate internal consistency. The Spanish version also exhibited good test-retest reliability and moderate convergent and discriminant validity. The younger participants (from 8 to 10 years) obtained higher means for total score and subscales than older participants (groups 11-13 and 14-18 years). Significant differences related to gender were also observed since males obtained higher means in Compulsions subscale. Despite more research is required, this results suggested that Spanish version of the Short LOI-CV showed a good psychometric performance assessing obsessive-compulsive symptoms in community population.
