Abstract

Objective. To determine the internal consistency, factorial structure, reproducibility and validity of criterion of the Leyton Obsessional Inventory in children and adolescents. Design. Study of validation with probabilistic sampling. Setting. Secondary schools in Bucaramanga, Colombia. Participants. A total of 581 students selected at random, of whom 38 did not answer, 8 were excluded because they were over 17, and 33 did not attend the clinical interview. Main measurements. The Inventory and the Structured Clinical Interview for axis I of the DSM-IV (SCID-I), clinical version, were used. Cronbach's alpha, factorial analysis, sensibility, specificity, probability, and Lin's coefficient were calculated. Results. The prevalence of obsessive-compulsive disorder was 11.8% (95% CI, 8.9-14.6). Cronbach's alpha was 0.803 and just one factor with 3.60 eigenvalue explained 74.8% of variance. The area under the ROC curve was 0.799 (95% CI, 0.752-0.847) and the best cut-off point was 12, with sensitivity at 69.5% (95% CI, 56.0-80.5) and specificity at 77.7% (95% CI, 72.9-88.9). Its reproducibility was acceptable (Lin's coefficient at 0.752; 95% CI, 0.714-0.790). Conclusion. The Leyton Obsessional Inventory is a fair screening tool for detecting obsessive-compulsive disorder in Colombian children and adolescents.
