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.

Objective: Oppositional Defiant Disorder (ODD) is a common disorder in preschool children.Evidence indicates that maternal and paternal psychopathology, particularly aggressive behavior and anxious-depressed symptoms, contributes to the development of this disorder. The latest research also suggests that ODD symptoms may exacerbate the mental health problems of parents. Our aim was to establish the existence of a reciprocal association between paternal and maternal psychopathology (aggression, depression and anxiety) and child ODD at age 3 and age 8, using a longitudinal design in a community sample of preschoolers. Method:The sample included 331 children evaluated at ages 3 and 8 through questionnaires and a semi-structured diagnostic interview with parents. Parents also informed about their own psychopathology.Results: At age 3 years, higher levels of ODD symptoms in girls were concurrently associated with maternal anxious/depressed symptoms and paternal aggressive behavior, and higher levels of ODD symptoms in boys were concurrently associated with maternal aggressive behavior.
