Resumen
La terapia cognitivo-conductual basada en Internet (iCBT) alcanzó a muchos adolescentes en Nueva Zelanda, mostrando una reducción de los síntomas comparable a los ensayos. Sin embargo, las bajas tasas de finalización subrayan la necesidad de abordar las barreras tecnológicas para las herramientas digitales de salud mental.
Área de la Ciencia:
- Salud mental digital
- Psicología adolescente
- Intervenciones de salud pública
Sus antecedentes:
- La terapia cognitivo-conductual basada en Internet (iCBT) es efectiva en ensayos clínicos, pero los datos de implementación en el mundo real son escasos.
- Este estudio examina la absorción y la eficacia de un programa de iCBT de libre acceso y sin guía para adolescentes en Nueva Zelanda.
Objetivo del estudio:
- Para evaluar la absorción, la adherencia y los cambios en los síntomas de la depresión en los adolescentes utilizando la intervención iCBT SPARX (pensamientos inteligentes, positivos, activos, realistas, factor X).
- Evaluar el impacto en el mundo real de una herramienta digital de autoayuda para la salud mental durante sus primeros 7 años de disponibilidad pública.
Principales métodos:
- Se puso a disposición de los adolescentes (12-19 años) en Nueva Zelanda una intervención iCBT de 7 módulos, no guiada y basada en el juego.
- La ingesta, la finalización del módulo y los cambios en los síntomas depresivos (medidos por PHQ-A) se analizaron en 21.320 usuarios registrados durante 7 años.
Principales resultados:
- Más de 21,000 adolescentes se registraron, y 13,564 comenzaron el programa SPARX.
- La gravedad de los síntomas se redujo significativamente desde el inicio hasta los módulos 4 y 7 (tamaños de efecto 0,38 y 0,51 respectivamente).
- Se observaron bajas tasas de finalización: el 51,1% completó el módulo 1, el 7,4% completó al menos 4 módulos y el 3,1% completó los 7 módulos.
Conclusiones:
- La intervención SPARX alcanzó una parte sustancial de la población adolescente objetivo, demostrando una eficacia comparable a los ensayos clínicos.
- Las bajas tasas de cumplimiento y finalización indican desafíos en el compromiso sostenido, potencialmente debido a barreras logísticas como velocidades de Internet lentas.
- Los datos de aplicación en el mundo real son cruciales para mejorar las herramientas digitales de salud mental, lo que requiere una adaptación continua a los avances tecnológicos y a las estrategias de participación de los usuarios.

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Interpersonal psychotherapy (IPT) is a structured, time-limited therapeutic approach initially developed to treat depression. It integrates key concepts from psychodynamic, humanistic, and cognitive-behavioral therapies, making it a uniquely eclectic framework. The therapy is rooted in the interpersonal theories of Adolph Meyer and Harry Stack Sullivan, as well as John Bowlby's attachment theory, and focuses on the interplay between interpersonal relationships and emotional well-being.
