Resumen El presente artículo analiza la violencia en el noviazgo mediante el estudio de sus tasas de prevalencia en Latinoamérica y Chile en las dos últimas décadas, comparándolas con los datos procedentes de otros países. Se constata la relevancia del problema en este último país, donde se llega al 51% en violencia psicológica y al 25% en la física. Se exponen además posibles causas de la poca relevancia y difusión de este problema en las políticas públicas, comparando metodologías e instrumentos de evaluación utilizados. Palabras clave: violencia en el noviazgo, prevalencia de violencia, salud mental juvenil.

This study compares attitudes toward teen relationship (or dating) violence (TRV) between early and late adolescents in the province of Concepción, Chile. The sample consisted of 770 adolescents, aged between 11 and 19 with an average age of 14.8 years old, of which 389 were female (50.5%) and 381 were male (49.5%). An adapted version of the Scale of Attitudes Towards Intimate Violence was used. Results found greater justifying attitudes toward violence in early adolescents than in late adolescents, in 6 of 12 items of the scale, with a statistical significance of p ≤ .001 in 4 items and in the overall score, and p ≤ .05 in 2 items. In the comparison according to sex, male adolescents tended to justify violence more than female adolescents did in one item ( p ≤ .001). In dating/no dating comparison, statistically significant differences were found in just 2 items, in favor of those who are not in a relationship ( p ≤ .05). These results are analyzed and discussed in relation to previous literature. Finally, orientations to future interventions are proposed, and it is suggested that aspects related to sampling and possible modulating variables such as cognitive development and moral development be considered for future investigations.

El presente ensayo revisa la importancia de evaluar el grado de aceptación de nuevas tecnologías en las instituciones de educación superior en Chile, como un insumo para la gestión del aseguramiento de la calidad. En particular, se analizan los modelos de aceptación de la tecnología y de marcos tecnológicos, enfatizando los beneficios que traería su utilización en dicho ámbito. Comprender y facilitar los procesos de aceptación de nuevas tecnologías en la IES, identificando los elementos que la obstaculizan, permite mejorar la implementación de mecanismos de aseguramiento de la calidad y volver más eficiente y eficaz el proceso formativo.Palabras claves. Aseguramiento de la calidad, resistencia a la tecnología, gestión en educación superior.Abstract. This essay reviews the importance of assessing the degree of acceptance of new technologies in the Chilean higher education institutions, as an input for managing quality assurance. Technology Acceptance and Technology Frames models are described, emphasizing their benefits in this field. Understanding and facilitating the process of new technologies acceptance in the organizations, by identifying those elements which hinder it, allows improving the implementation of quality assurance mechanisms in order to make the educational process more efficient and effective.

While several programs have been developed to prevent dating violence, few have been evaluated. Likewise, few studies have documented adolescents' viewpoints on how prevention should be done. The current qualitative study seeks to strategically fill a gap in knowledge regarding the points of view of Chilean adolescents about the strategies that are best suited to prevent this problem and what is relevant content for prevention programs. This paper is part of a broader study on adolescents' social representations of dating violence. The study's aim was to explore Chilean adolescents' points of view about asking for help and their suggestions about how to prevent dating violence. The sample included 48 Chilean adolescents, 26 girls (54.1%) and 22 boys (45.8%) between 14 and 18 years old, recruited from public and private schools, who were interviewed with a focus group method. The study consisted of two phases; the results of the second phase are discussed in this manuscript. The results are useful for the development of an appropriate socio-political response to this social and public health problem. Participants identified friends and parents as more common sources from whom to seek help than teachers and health professionals. The severity of dating violence and ensuing injuries are the main reasons for asking for help. In addition, gender is considered a central prevention issue in a changing Chilean cultural context. According to the ecological systems theory, prevention strategies based on the environment of adolescents at multiple levels (individual, interpersonal, community, and social) and in multiple components have been recommended.
