Adaptación del Inventario de la Triada Cognitiva Infantil en población española

Abstract

Depression is one of the mental disorders that concern world-wide. One theory that has attracted more researches is the Beck's cognitive theory of depression. The Cognitive Triad Inventory (CTI) has been devel-oped to evaluate the different components of the cognitive triad, although most studies had been developed in adult and adolescent population. The aim of this work is to show evidence of factorial validity of the reduced version of the CTI, and the study of the psychometric properties of the inventory in children. In the sample of 3292 children with age between 8 and 13 (M=9.86; SD =1.24), the results showed a better factorial fit with a bi-factorial model (positive triad and negative triad). The reliability of the di-mensions is good (α=.88 and .92 respectively) and convergent validity evi-dence is adequate. The inventory was evaluated from the Item Response Theory framework, showing correct properties. Finally the norms of the questionnaire were made addressing the gender differences that were found previously.
