Introduction
Currently I am an Assistant Professor of the Practice at Boston College. Most of my research has focused on social issues that affect youth's positive development. My main areas of interest are youth violence, community violence prevention programs, especially youth mentoring initiatives, youth and public policy, and undocumented migration to the United States among Salvadoran youth.

La resiliencia es un concepto que ha ganado gran popularidad dentro y fuera de la academia, particularmente en las últimas dos décadas. Su extensa aplicación en la psicología ha permitido comprender cómo las personas logran adaptarse satisfactoriamente a las constantes demandas medioambientales y sobreponerse a la adversidad, pero también ha hecho mucho más difícil la tarea de definir la resiliencia con claridad. La pregunta clave que este trabajo busca responder es ¿qué debemos de entender por resiliencia y cómo podemos fomentarla? Para ello se ofrece una revisión sistemática y crítica de cómo la resiliencia ha sido definida, investigada, medida y aplicada desde la psicología en las etapas del desarrollo de la niñez y la adolescencia. Mediante el análisis conceptual también se revisan sus usos, atributos, antecedentes, consecuencias, referentes empíricos y casos modelo. Esta revisión permitirá clarificar conceptos clave en la investigación y diseño de intervenciones para la prevención del riesgo y la promoción del bienestar en niños y adolescentes. Dadas las condiciones de exclusión, inequidad y riesgo social en Latinoamérica, la resiliencia —desde sus múltiples definiciones y perspectivas— puede fomentarse por medio de políticas públicas que permitan incrementar el desarrollo humano pleno, saludable y sostenible.

In order to understand the factors underlying the intent to migrate, particularly to the U.S., among middle (15-17 years old) and late (18-21 years) adolescents from El Salvador, this study proposes a comprehensive model of determinants of migration while controlling for several demographic and household characteristics. The model includes factors such as trust in institutions and political actors, positive attitudes toward migration, social capital, life satisfaction, future orientation, and religiosity, among others. Data for this study came from the National Youth Survey from the Salvadoran Youth Institute. By testing both groups separately among 765 middle and 795 late Salvadoran adolescents (N = 1,550), it is possible to distinguish and compare the unique determinants of migration for those who are still considered minors and those who have surpassed the legal threshold of adulthood and reached the last stage of adolescence. This analytical strategy underscores the importance of examining the determinants of international migration from a developmentally appropriate perspective. In addition, it provides comparative findings that can inform policies and shed light on the immigration process of Salvadoran adolescents.

Several researchers have studied the negative effects that victimization can have on the mental health of children and adolescents. Although the likelihood of experiencing posttraumatic symptomatology increases as a result of being polyvictimized, not everyone ends up developing or showing signs of high levels of psychological distress. Understanding the risk and protective variables that may buffer or explain the underlying mechanisms of the relationship between polyvictimization and posttraumatic symptomatology will help bring to light why victimized adolescents’ mental health is affected differentially. A sample of 1,024 adolescents between the ages of 12 and 18 years old in 24 schools in the Metropolitan Area of San Salvador was surveyed for this study. Using path analysis, a number of exploratory models will be examined to determine the conditional effects of community disorganization on coping strategies and social support as mediators of the relationship between polyvictimization and PTS symptomatology. The findings of this study will enrich the growing body of knowledge that explains the complex mechanisms and factors underlying the mental health of polyvictimized adolescents.
