The Leyton Obsessional Inventory for adults was modified for children and administered to 26 adolescents ( age 14.3 ± 2.1 years) meeting DSM-III criteria for obsessive compulsive disorder, 14 adolescents ( age 13.7 ± 1.7 years) having severe obsessive symptoms but who had received other primary psychiatric diagnoses, and 28 normal adolescent controls ( age 13.7 ± 1.9 years). The Leyton Obsessional Inventory-Child Version (LOI-CV) significantly differentiated obsessive patients from normal controls on total scores for obsessional symptoms as well as total scores for degree of resistance to the symptoms and interference with everyday life. Patients and psychiatric controls differed significantly on scores for resistance and interference. Test-retest reliability for patients was demonstrated and scores differentiating placebo and active drug treatment indicated further clinical validity. However, LOI-CV scores did not correlate significantly with other clinical measures of obsessive behavior (Obsessive Compulsive Rating Scale, Comprehensive Psychopathological Rating Scale, NIMH Global and Obsessive Compulsive Scales) obtained at baseline.
