ResumenDebido a la alta tasa de trastornos ansiosos, depresivos y estrés en universitarios, es necesario contar con un instrumento estandarizado en esta población, que permita detectar estas patologías para intervenir oportunamente. Por ello, el objetivo de este trabajo fue determinar las características psicométricas de las Escalas Abreviadas de Depresión, Ansiedad y Estrés (DASS -21) en universitarios chilenos, lo cual contempló la validación del mismo. La muestra estuvo constituida por 484 estudiantes de la Universidad Austral de Chile, seleccionados mediante un muestreo probabilístico por conglomerados, utilizando un diseño correlacional transversal. La validez de constructo se verificó mediante análisis factorial exploratorio, el que arrojó una estructura de tres factores, explicando el 49,99 % de la varianza total. La validez concurrente y divergente fue verificada con el BAI, BDI -II y SCL -90 -R. Mediante Alpha de Cronbach se constató la adecuada confiabilidad y consistencia interna del DASS -21. Palabras clave: DASS -21, validación, universitarios. abstractThe high rate of anxiety disorders, depression and stress detected in Chilean university students requires a standardized instrument of diagnosis, enabling timely intervention for these disturbances. The aim of this study was to determine the psychometric properties of the Abbreviated Scales of Depression, Anxiety and Stress (DASS-21) for Chilean university students, thus validating the scale. The sample consisted of 484 students of Universidad Austral de Chile selected through random sampling using a cross-sectional correlation design. Construct validity was verified by exploratory factor analysis which yielded a three-factor structure, explaining 49.99% of total variance. Concurrent and divergent validity was verified by the BAI, BDI-II and SCL-90. Adequate reliability and internal consistency of DASS-21 was found using Cronbach's Alpha.

The use of scales to measure constructs in populations or contexts other than that in which they were established is highly controversial. Despite this, the use of scales without reference to “local” psychometric data is still widespread. In this study we examined the factor structure of the short 21-item form of the Depression, Anxiety, and Stress Scales (DASS-21), when it was applied to adolescent samples recruited from high schools in Australia (N = 371), Chile (N = 448), China (N = 558), and Malaysia (N = 388). Multigroup confirmatory factor analyses revealed that the purported three-factor structure of the DASS-21 was supported in each location with structural invariance across locations. While convergent and divergent validity studies are required to support this finding, the DASS-21 appears to be suitable for use with adolescents in these locations.

Adultez Emergente y características culturales de la etapa en universitarios chilenos Emerging Adulthood and Cultural Characteristics of the Stage in Chilean University Studentsana Barrera-Herrera eugenia V. Vinet Resumen la adultez emergente es un periodo de vida entre los 18 y 29 años, culturalmente construido y no de carácter universal. ante la escasez de estudios en esta etapa en chile, el objetivo de esta investigación fue caracterizar la adultez emergente, y determinar sus rasgos más relevantes en universitarios chilenos, a través de una aproximación cualitativa, desde los protagonistas. seis grupos focales conformados por 60 universitarios a nivel nacional analizaron los ítems del inventario de Dimensiones de adultez emergente o discutieron sus creencias sobre tres áreas definidas a priori: Identidad y Autoconcepto, Relación con los padres y salida del hogar, y amor y sexualidad. se evidencia la presencia de la adultez emergente en universitarios, pues las características centrales de la teoría están presentes en este grupo, y se obtiene evidencia de aspectos de carácter cultural propios de los universitarios chilenos, relacionados a la importancia de los vínculos familiares y sociales. Palabras clave: Adultez emergente, Psicología del Desarrollo, Universitarios, Cultura. Abstractemerging adulthood is a period of life between 18 and 29 years old, culturally constructed and not universal. given the paucity of studies about this developmental stage in chile, the objective of this research was to characterize emerging adulthood and determine its most important features in chilean university students using a qualitative approach, focused at the protagonists themselves. six focus groups formed by 60 university students revised the items of the inventory of Dimensions of emerging adulthood (iDea) or discussed their beliefs about three areas defined a priori: Identity and self-concept, Relationship with parents and leaving home, and love and sexuality. the presence of the emerging adulthood stage in university students is evident since its central features are present in this group; also there is evidence of others aspects that belong to cultural characteristics of the own chilean university students which are related to the importance given to the family and social relationships.
