Résumé
"We assessed the factor structure, validity and reliability of the Spanish version of the Leyton Obsessional Inventory-Child Version (LOI-CV) and determined the optimal cut-off score for detecting obsessive-compulsive disorder (OCD). A total of 1,514 students (aged 8-12) participated in the first phase of the study and 562 of these participated in the second phase (participants at risk of mood and anxiety disorders and controls without risk). The LOI-CV was administered in both phases and the OCD diagnosis was made in the second phase. In the exploratory factor analysis, we obtained three factors that explained 45.84% of the variance: Order/checking/ pollution, Obsessive concern and Superstition/mental compulsion. The reliability was good (.79-.90). The cut-off scores selected were 21 for the total score and 10 for the interference score, both of which had a sensitivity of 82.4% and a specificity of 84.1% and 83.8%, respectively, for detecting OCD. LOI-CV scores were significantly higher in children with OCD diagnosis than in children with subclinical diagnosis and children without diagnosis. There were no gender or age differences in the LOI-CV scores. The results support the validity and reliability of the LOI-CV as a screening test for OCD in a non-clinical population."
