title: Modification and factorial analysis of the Leyton Obsessional Inventory.
abstract: The Leyton Obsessional Inventory was modified into a paper-and-pencil form to facilitate its group administration. Factor analysis was carried out on the modified version replies of 173 college students. The factors obtained were compared to those extracted by Cooper and Kelleher (1973) for the original inventory. Similarities and differences in factors were attributed to cultural factors and differences in the sample populations. The treatment implication of obtaining multiple symptom factors in future studies with obsessional patients was stressed.
