Background: The relationship between selfie addiction and narcissism in students at the Universidad Autónoma de Zacatecas (UAZ, Autonomous University of Zacatecas), Mexico, was analysed. The aim of this study was to identify the narcissistic factors associated with students’ selfie taking addiction. Methods: To identify the relationship between narcissism and selfie addiction, the Narcissistic Personality Inventory (Adapted NPI-40) and the Psychometric Selfie Addiction Scale (PSAS) were used. A structural equation model (SEM) was employed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for structural validation. EFA and CFA confirmed adequate fit and reliability indicators regarding the robust unidimensional structure of the PSAS. Results: The SEM results indicated significant associations between the latent dimensions of the narcissistic traits of superiority, authority, need for admiration, exhibitionism, and exploitation and selfie addiction. This research provides structural and psychometric evidence for the relationship between narcissism and selfie addiction in the Mexican student population, integrating Adapted NPI-40 and PSAS, as well as a parsimonious explanatory structural equation model that demonstrates the relationship between different narcissistic traits and social media practices. Conclusions: The results provide a basis for developing digital literacy interventions for young people and future cross-validations.

La Unidad Académica Preparatoria de la UAZ, no cuenta con un sistema de alertas tempranas. El problema de esta investigación la falta de un sistema de alertas tempranas en la Preparatoria de la UAZ que permita al docente y personal administrativo identificar situaciones de riesgo que incremente el índice de deserción y reprobación. Se pretende conocer si las acciones que el personal docente y administrativo implementa dentro del aula, pueden clasificarse como un sistema de alerta temprana que permita al estudiante enfocarse en su desempeño académico haciendo consciente su paso por el programa. Trabajo observacional sustentado en la teoría fundamentada constructivista y la muestra es a juicio de expertos para encuestar a administrativos, docentes y estudiantes, estos últimos con la característica de ser integrantes del grupo desde segundo semestre (ago-dic 2023), tercero (ene-jul 2024) y cuarto (ago-dic 2024). Los hallazgos son: las estrategias implementadas por docentes no están sistematizadas en un reporte de alerta, los administrativos atienden las incidencias y falta de cumplimiento que los docentes reportan de los alumnos y dan seguimiento de rutina sin contar con procedimiento avalado por la autoridad académica de la Preparatoria, corroborando la urgencia de trabajar en la construcción de este Sistema.

Background: The relationship between the dimensions of selfie addiction and narcissism in students at the Universidad Autónoma de Zacatecas (UAZ, Autonomous University of Zacatecas), Mexico, was analysed. The aim of this study was to identify the factors of narcissism associated with students' addictive behaviour towards selfies. Methods: To identify the relationship between narcissism and selfie addiction, the NPI-40 Narcissistic Personality Inventory and the Psychometric Selfie Addiction Scale (PSAS) were used. This was done using a Structural Equation Modelling (SEM). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to carry out the structural validation process. EFA and CFA confirmed adequate fit and reliability indicators regarding the robust multidimensional structure of the Selfie Addiction Scale. Results: SEM indicated that narcissistic traits predict selfie addiction. It also indicated that there is body objectification and appearance comparison through social media. This research provides important findings on recent structural and psychometric evidence in the Mexican student population, as it integrates the NPI-40 and PSAS, as well as a parsimonious explanatory Structural Equation Modelling that demonstrates the relationship between narcissistic traits and social media practices. Conclusions: The results provide a basis for developing digital literacy interventions for young people and future cross-validations.
