This study has three primary objectives:
1. To adapt the Spanish version of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP; Barlow et al., 2011, 2019a, 2019b) for delivery in a group format within the Spanish Public Mental Health System for adults diagnosed with emotional disorders.
2. To evaluate the effectiveness of the intervention.
3. To assess its clinical feasibility and acceptability in routine clinical practice.
Outcomes will include anxiety, depression, somatic symptoms, transdiagnostic variables, functional impairment, quality of life, and participant satisfaction. These outcomes will be assessed at baseline, post-treatment, and 3-month follow-up.
The intervention is expected to improve emotional symptoms, functional impairment, and quality of life. In addition, the study will explore whether this group-based transdiagnostic approach may help lower demand on public mental health services.
