(1) Background: Discrepancies between children’s self-reports and their parents’ reports on mental health indicators are associated with measurement errors or informant bias. However, they are a valuable tool in understanding the course of child psychopathology. This study aims to determine the level of discrepancies between parents’ perceptions and children’s self-reports in mental health indicators in Northern Chile. (2) Methods: A System of Evaluation of Children and Adolescents self-report (Sistema de Evaluación de Niños y Adolescentes, SENA) was responded to by 408 students between 8 and 13 years old and their parents. (3) Results: Children reported a significantly higher frequency of emotional problems, defiant behavior, and executive functions as compared to their parents’ responses. (4) Conclusions: There is a disjunction between the report of parents and children, which could originate in poor family communication.

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.

El propósito de este estudio fue evaluar la asociación entre los problemas de regulación emocional e indicadores de salud mental en adolescentes de la ciudad Arica al Norte de Chile, además de describir y comparar los niveles de problemas interiorizados y exteriorizados entre hombres y mujeres. Participaron 2331 estudiantes de 11 a 20 años provenientes de establecimientos educacionales. Para medir los problemas de regulación emocional y los indicadores de salud mental, se utilizó el Sistema de Evaluación de Niños y Adolescentes (SENA). Los resultados muestran que los problemas de regulación emocional poseen efectos grandes y significativos sobre los problemas interiorizados y exteriorizados. Asimismo, se observó que las mujeres presentan mayor sintomatología depresiva, ansiosa, de ansiedad social y problemas de regulación emocional que los hombres. Pareciera ser que los adolescentes que manifiestan problemas para regular sus emociones son más vulnerables a experimentar estados de ánimos disfóricos, preocupaciones recurrentes o comportamientos disruptivos.

Resumen: Las enfermedades mentales son comunes, crónicas y discapacitantes, y representan un problema de salud pública importante en nuestro país y en todo el mundo. Para las enfermedades mentales más comunes, disponemos actualmente de intervenciones médicas y psicosociales con eficacia probada. Sin embargo, estas aún son insuficientes, y su disponibilidad no se condice con la alta morbilidad y mortalidad que encontramos para las enfermedades mentales. En respuesta a esto, en los últimos 15 años se ha realizado un esfuerzo considerable para desarrollar técnicas de detección temprana, para personas con alto riesgo clínico de desarrollo de enfermedad mental, e intervenciones precoces para prevenir o retrasar la progresión a la enfermedad completa. Un mayor énfasis en la salud mental y la integración de la atención a la salud mental en todos los programas de desarrollo pertinentes, fortalecerán el esfuerzo general de desarrollo, así como garantizará, por primera vez, la atención sostenida de la inversión y la investigación al principal contribuyente mundial de la pérdida de productividad y carga de enfermedad.
