Effectiveness of a blended group transdiagnostic treatment for emotional disorders: Study protocol for a randomized controlled trial

Emotional disorders (ED) (mood and anxiety disorders) are very prevalent and disabling, and often appear in comorbid presentations. Although there are effective treatments for these disorders, there is still a large gap between the number of people who need them and those who actually receive them. The combination of three strategies may help in this regard, facilitating the dissemination and accessibility of treatment: the transdiagnostic perspective of ED, the group format, and the use of technologies in a blended format (i.e., the combination of online and face-to-face therapy elements). This study intends to compare the efficacy of a new ED intervention, a transdiagnostic group treatment protocol administered in a blended format, with that of a face-to-face treatment. This article describes the study protocol for the randomized controlled trial.
