Abstract
This study compared a parent-report measure of childhood OCD symptoms, the survey form of the Leyton Obsessional Inventory - Parent Version (SLOI-PV), with a youth self-report measure, the survey form of the Leyton Obsessional Inventory - Child Version (SLOI-CV); specifically, the psychometric properties of the scales were examined, along with their efficacy in discriminating youth with OCD symptoms from other clinically-referred and normal youth. Participants were 72 youth-parent pairs. Youth ranged from 9 to 18 years of age; 31 youth were diagnosed with OCD or obsessive-compulsive behaviours (OCB), 11 youth were clinical controls and 30 were normal controls. The psychometric properties of the SLOI-PV and SLOI-CV were adequate and an optimal cut-off score of 15 was found for both scales. The parent-rated scale, the SLOI-PV, was more accurate in classifying the youth into the three groups and more sensitive to OCD symptoms than the SLOI-CV. Implications of these findings are discussed in view of the potential use of the SLOI-PV as a screening tool for identifying childhood OCD in community and clinical populations.
