    Implicancias del ciberacoso en el desarrollo de sintomatología depresiva mayor en jóvenes entre 15 y 29 años en Chile
    (2024) Rojas, Fernanda; Bravo, Constanza; Miranda, Rafael; Varela, Jorge; Pacheco, Emanuel
    El uso de medios digitales de comunicación y socialización entre los jóvenes trae consigo nuevos estresores, riesgos y formas de agresión, como el ciberacoso. Objetivo: evaluar la relación entre el ciberacoso (CB) y la sintomatología asociada a la depresión mayor (SDM) en jóvenes chilenos entre 15 y 29 años. Métodos: encuesta a través de la plataforma StatKnows. El muestreo fue de carácter probabilístico y estratificado con afijación proporcional al tamaño de selección bifásica. Se accedió a la muestra y a los datos de forma virtual, respetando los estándares bioéticos de la investigación con humanos. Resultados: en todas las edades estudiadas, aumenta la probabilidad de experimentar sintomatología depresiva a medida que aumentan los niveles de ciber agresión, especialmente en el grupo comprendido entre 19 a 24 años. Conclusiones: los resultados obtenidos reflejan diversos factores de la adultez-emergente que otorgan mayor vulnerabilidad a este grupo, y ponen énfasis en la importancia de estudiar el fenómeno en edades no escolares, dado que esta forma de agresión no es exclusiva a la adolescencia y tampoco lo son sus efectos en la salud mental.

    Instruments for measuring hedonic and eudaimonic well-being of adolescents in the Latin American school contexts: a systematic review
    (2025) Bravo-Sanzana, Mónica; Casas, Ferran; Rodríguez-Rivas, Matías E.; Oriol, Xavier; Varela, Jorge; Miranda, Rafael; Terán-Mendoza, Oscar
    Well-being is crucial for understanding adolescent health and quality of life and is related to positive physical, emotional, and social indicators. This systematic review developed from PRISMA criteria sought to identify and evaluate instruments in Latin America to measure hedonic and eudaimonic well-being in adolescents. A total of 1737 articles were identified in the Web of Science (WOS), Scopus, ScieLO, and PsycINFO databases, with the search limited to scientific articles published after 2010. Of these, 45 met the inclusion criteria and were synthesized in this review. Most of the studies focused on hedonic well-being, especially life satisfaction, while eudaimonic well-being was less explored; in addition, some studies were identified that do not have a clear theoretical approach, and only two studies considered a multidimensional perspective of well-being. By way of conclusion, the diversity of instruments to assess well-being in Latin America is highlighted, and it is proposed that future research should incorporate solid theoretical models and a comprehensive understanding of adolescent well being in the region; in this way, the present study provides a basis for future research that includes the application, design or validation of instruments with a comprehensive theoretical model of adolescent well-being in the Latin American context.

    Bullying victimization and subjective well-being in 10- and 12-year-old children from 24 countries: The buffering effect of family and teacher support
    (2025) Oriol, Xavier; Miranda, Rafael; Varela, Jorge; Garcia, Nuria
    Bullying victimization in children is a recognized public health concern in many countries worldwide. Specifically, studies have consistently demonstrated that bullying victimization is one of the indicators that most significantly and negatively influences the subjective well-being (SWB) of children. Following this assumption, a study was conducted to examine the impact of bullying victimization on subjective well-being among 75,877 students aged 10 and 12 years across 24 countries. Additionally, the moderating role of support from teachers and family members in the relationship between bullying victimization and subjective well being was investigated using structural equation modeling (SEM) analysis. The results show that, in many countries, there is an interaction effect of both family support and teacher support figures in both age groups (10 and 12 years). However, significant variability in these interaction effects was observed across countries, and in some countries, no moderating effect was detected. Specifically, in the 12-year-old group, a larger number of countries show no interaction effect from any adult support figure in the relationship between bullying victimization and SWB. The findings are discussed with a focus on the buffering effects of both types of support, the variability observed across countries, and the practical implications of these results.
