Adaptación y validación de la versión chilena del cuestionario para evaluar el desarrollo de la identidad en adolescentes (AIDA)

The aim of this study was to adapt and validate the Chilean version of a questionnaire that allows to assess the Development of Identity in Adolescents (AIDA), as well as propose a two-factor structure model. The sample consisted of 725 adolescents between the ages of 12 and 18 years old, belonging to different socioeconomic levels from Santiago, Chile. A Bifactor model using Exploratory Structural Equation analyzes were performed to estimate a general factor (Identity Diffusion), and six specific factors that absorb residual variability of this main factor. The results indicated a high internal consistency for the total score (.94), as well as moderate to high for almost all sub-factors, except one of them. It was possible to conclude that the Chilean AIDA has a good reliability and, an adequate concurrent and discriminative validity that can be a use to differentiate adolescents with an integrated identity from those with an identity diffusion, emphasizing that identity is a multidimensional construct that must be measured under this assumption.
