Effectiveness of the Group Unified Protocol for Emotional Disorders in Adults in a Public Mental Health Setting

Официальное название

Effectiveness of the Group Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP; Barlow et al. 2011, 2019a, 2019b) in Adults in a Public Mental Health Setting

Обзор

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.

Подробное описание

Anxiety and depressive disorders are among the leading causes of disability and contributors to the global burden of disease worldwide. To address this public health challenge, stepped-care models have been developed to organize treatment according to patients' clinical needs and progression. Within this framework, the transdiagnostic approach proposes that emotional disorders share common underlying transdiagnostic mechanisms, including elevated negative affect and maladaptive emotion regulation strategies such as emotional avoidance.

Accordingly, the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) has emerged as an evidence-based intervention for anxiety, depressive, and related emotional disorders. The UP aims to enhance adaptive emotion regulation and lower maladaptive behavioral avoidance, thereby promoting improvements across a broad range of emotional symptoms.

This study aims to adapt and implement the Spanish version of the UP in a group format for adults diagnosed with an emotional disorder receiving treatment within the Spanish Public Mental Health System. In addition, the study will evaluate the intervention's effectiveness, feasibility, acceptability, and cost-effectiveness. The intervention will be delivered in Public Mental Health Units of the La Rioja Health Service.

Adults aged 18 to 65 years diagnosed with an emotional disorder will be recruited. The study will employ a randomized controlled trial design with two parallel groups: a Treatment as Usual (TAU) group and an experimental group (UP + TAU). Assessments will be conducted at pre-treatment, post-treatment, and 3-month follow-up. Outcome measures will assess anxiety, depression, somatic symptoms, transdiagnostic processes, functional impairment, quality of life, participant satisfaction, and intervention cost-effectiveness.
