Analysis of psychometric properties of the suicide risk inventory (irisa) for Colombian adolescents

Abstract:

This study presents the analysis of the psychometric properties of the Suicide Risk Inventory for Adolescents-IRISA, by (Hernández-Cervantes & Lucio, (2006) , in Colombian teenagers. The sample comprises 526 schooled teenagers. To establish the convergent validity of IRISA with other tests, the Suicide Risk Scale (Bahamón & Alarcón, 2018) and the Ryff Psychological Wellbeing Scales by Ryff (adapted by Van Dierendonck, 2004, and translated into Spanish by Diáz et al., 2006) were applied. The IRISA showed good global consistency (α=.962), and in the subscales, high levels of reliability that vary between .798 to .966. The confirmatory factor analysis showed yielded acceptable levels of adjustment and goodness. The confirmatory factor analysis had acceptable goodness of fit. Convergent validity was also identified with the other instruments used. It was concluded that the IRISA meets criteria of internal consistency, construct validity and convergent validity to be applied in Colombian adolescents.
