PurposeComputerized cognitive behavioral therapy (CCBT) has been shown to be efficacious. Moreover, CCBT can be enhanced by using physiological and activity sensors, but there is no evidence about the acceptability of all these tools. The objective of this study is to examine the efficacy, expectations, satisfaction, and ease of use of an Internet-based CCBT program for preventing depression, with and without sensors (electroencephalography, electrocardiograhpy ECG, and actigraphy), in a high-risk population (unemployed men).Patients and methodsSixty participants at risk of depression (unemployed men) were randomly assigned to three experimental conditions: 1) intervention program (N=22), 2) intervention program plus sensors (N=19), and 3) control group (N=19). Participants completed depression, anxiety, positive and negative affect, and perceived stress measures. Furthermore, they also completed the measures for expectation, satisfaction, and the ease of use of the program.ResultsResults showed that the two intervention groups improved significantly more than the control group on the clinical variables, and the improvements were greater in the group that used sensors than in the group that did not use them. Furthermore, participants in both intervention groups scored high on expectations and satisfaction with the CCBT program (with and without sensors). The mean score for usability was 88 out of 100 (standard deviation =12.32). No significant differences were found between groups on any of these variables.ConclusionThis is the first study to analyze the efficacy, expectations, satisfaction, and ease of use of an Internet-based program using physiological and activity sensors. These results suggest that an Internet program for depression with or without physiological and activity sensors is effective, satisfactory, and easy to use.
ResumenIntroducción: En el año 2020 la depresión alcanzará el segundo lugar del ranking de los Dalys (Disability Adjusted Life Years), por ello su prevención es un punto central en el Pacto Europeo para la Salud Mental y el Bienestar. Actualmente, menos del 50 % de las personas afectadas recibe el tratamiento correcto. El uso de internet facilita el acceso a los Tratamientos Basados en la Evidencia Además, es importante desarrollar programas de prevención. Nuestro grupo ha desarrollado un programa preventivo, de corte cognitivo comportamental, auto-aplicado a través de Internet. Sonreír es Divertido combina los procedimientos eficaces para el manejo del estrés, la regulación emocional, la capacidad de afrontamiento y la resiliencia. metodología: La muestra está compuesta por nueve participantes varones desempleados. La media de edad es de 36-33 (sD = 10-759), con un rango de 22 a 50 años. Se utilizaron: Escala general de Gravedad e Interferencia de la Ansiedad y de la Depresión, Inventario de Depresión de Beck-II y Escala Multidimensional de Estilos de Afrontamiento. Resultados: No hay diferencias estadísticamente significativas del pre al postratamiento, a excepción de la subescala de Aceptación del Brief Cope (z = -2, 27; p < ,05). En el resto de variables, las medias muestran una tendencia a la mejoría. Conclusión: Este programa puede ser útil como estrategia para la prevención, ya que, a pesar de que los participantes estaban pasando por una situación difícil, se observa una tendencia a la mejoría.Palabras clave: terapia basada en Internet, prevención, depresión, capacidad de afrontamiento, regulación emocional.
