Análisis Psicométrico del Inventario de Orientaciones Suicidas ISO-30 en Adolescentes Escolarizados (14-18 años) y Jóvenes Universitarios Marplatenses

Abstract

The Inventory of Suicide Orientation ISO-30 is one of the most widely employed scales in Argentina. This paper aims to analyse the psychometric features of the scale in a sample of adolescent students and young college students from Mar del Plata, Buenos Aires. The study entailed two phases. The exploratory phase took into account 821 cases (62.5% female, 37.5% male; Mage=16.40; DS=1.09) and carried out evidences of content validity analyses and an exploratory factor analysis. The confirmatory phase included 297 adolescents and young adults (all students, 67% female, 33% male; Mage=16.78; DS=2.02). A confirmatory factor analysis and internal consistency analyses were conducted. Furthermore, the dimensional model obtained was compared to the previous model. Results allowed to present a shorter version of the scale, ISO-19 which, despite of its differences with the original version, ISO-30 showed adequate psychometric evidences which support and justify its applicability.
