Purpose of review: Social Contagion is defined as the spread of behaviors, attitudes, and affect through crowds and other types of social aggregates from one member to another. Adolescents are prone to social contagion because they may be especially susceptible to peer influence and social media. In this article, we provide a brief review of the most recent findings on social contagion, violence, and suicide among adolescents. Recent findings: Recent evidence support social contagion in gun violence, bullying, cyberbullying, violent offending, and suicide, but is inconclusive on the role of violent video game exposure on aggressive behavior. Summary: The mechanisms underlying the contagion effect of violence and suicide are currently unclear. It has been argued that social learning, identification with significant others, and the normalization of specific norms play a role. All these mechanisms require understanding social contagion as a complex interaction between individual, relational and social factors. This is key if the social contagion perspective is to be used not only to investigate negative outcomes, but also as a framework for promoting prosocial attitudes and behaviors. Additionally, more research is needed on psychosocial interventions and public policies to minimize the potential spillover effect of violence and suicide.

Realizamos una revisión de alcance sobre la prevalencia de síntomas psicológicos, factores asociados a la salud mental, barreras y facilitadores para la búsqueda de ayuda, y la efectividad de intervenciones de salud mental en estudiantes de educación superior en Chile. Buscamos reportes indexados hasta el 15 de octubre de 2019 en las bases de datos CINAHL, Google Scholar, PubMed, Virtual Health Library/BIREME y Web of Science. Evaluamos la calidad de los estudios de prevalencia y exploramos la prevalencia combinada de síntomas psicológicos mediante meta-análisis. Incluimos 32 estudios publicados, 20 sobre prevalencia de síntomas – 10 con la calidad suficiente para ser incluidos en el meta-análisis. Observamos una heterogeneidad sustantiva en la exploración de prevalencia combinada de síntomas, con rangos entre 22,9% a 40,7% para malestar psicológico, 16,5% a 38,8% para síntomas depresivos, 16,5% a 23,7% para síntomas ansiosos, 19,7% a 29,7% para consumo de cannabis en los últimos 12 meses, y 84,0% a 92,6% para consumo de alcohol en los últimos 12 meses. El sexo femenino se asoció consistentemente con problemas de salud mental. Es necesario realizar más estudios que evalúen el acceso a tratamiento, facilitadores y barreras para la búsqueda de ayuda, e intervenciones para mejorar la salud mental de la población objetivo.

En población adolescente se ha observado una prevalencia durante la vida de 2,2%4 y durante los últimos 12 meses de 1,1% en Estados Unidos5, y de 2,6% durante los últimos 12 meses en Chile6. El TAG en la adolescencia muestra una alta comorbilidad con otros trastornos de ansiedad y depresión, deterioro funcional y persistencia7. Además, en adultos con TAG se ha encontrado que a mayor nivel de síntomas y duración de la enfermedad, hay mayor reducción de la materia blanca cerebral8. Debido a todo esto es importante su detección temprana y tratamiento.

The rapid internet penetration in Latin American countries has made it possible to implement digital mental health interventions. “Cuida tu Ánimo” (Take Care of Your Mood) is an internet-based program for the prevention and early intervention of depression in adolescents. A pilot study was conducted in Chile and Colombia to study the feasibility and acceptability of the program and estimate its effects. There were 199 participants (53.3% women; mean age = 14.8 years, SD = 1.0) recruited from two schools in Chile and two schools in Colombia. Qualitative and quantitative methods were applied for data collection and analyses. Although the levels of acceptance were moderate to high across all variables, adherence was lower than expected. The participants deemed important for an intervention of this type offered a higher level of interaction with team members through internet-based and face-to-face activities. Post-intervention outcomes show a reduction in depressive and anxious symptoms in adolescents in Chile, while there were no significant changes in the level of symptomatology in adolescents in Colombia. The women used the program more than the men. Results show the need to improve the intervention by increasing its levels of customization and developing strategies to achieve better adherence. The contradictory results of the program in Chile and Colombia suggest the importance of other variables beyond the content of the intervention, such as the setting or context of the intervention.
