An interventional study of UP-A in Anxiety Disorders, Depressive Disorder and Emotional Disorder, sponsored by Universidad Nacional de Educación a Distancia. Completed at 1 site in Spain. Open to participants aged 11 Years to 18 Years. Per ClinicalTrials.gov, last updated 2025-09-16.

The study aims to adapt the Spanish version of the UP-A to a group format in a public mental health setting for adolescents with moderate emotional symptoms and evaluate its clinical utility and feasibility. This includes assessing anxiety, depression, transdiagnostic variables, engagement, and satisfaction from adolescents, parents, and clinicians, with follow-ups at 3, 6 and 12 months. The goal is to improve adolescent mental health and explore whether this approach could help alleviate the pressure on public healthcare services.
Anxiety and depression are among the most prevalent mental health disorders in adolescents, with growing concerns about their increasing incidence. Studies indicate that emotional disorders often co-occur due to shared transdiagnostic factors, such as poor emotion regulation, high negative affect, and cognitive avoidance. Given these shared mechanisms, transdiagnostic treatments like the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) have been developed to improve adaptive emotion regulation and reduce avoidance behaviors. While the UP-A has been primarily evaluated as an individual therapy, its adaptation to a group format could enhance accessibility and efficiency, particularly in public mental health settings.
This study aims to adapt the Spanish version of the UP-A to a group format for adolescents with moderate emotional symptoms in a public mental health setting and assess its clinical utility and feasibility. The program is administered at a public mental health center in Madrid, with 31 adolescents (ages 11-17) diagnosed with emotional disorders. The intervention consists of 16 weekly sessions for adolescents, alongside three parental sessions. The program incorporates modifications such as individual sessions for defining personal treatment goals, structured peer support, and behavioral reinforcement strategies.

DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

Intervention Group of an uncontrolled study.
Behavioral: UP-A
The intervention is a group adaptation of the Spanish version of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A; Ehrenreich-May et al., 2018, 2020, 2022). It consists of 16 weekly 90-minute sessions held in person at a public Mental Health Center. The intervention also includes three in-person group sessions for parents, each lasting one hour, held at the beginning, middle, and end of the program. These sessions cover content from the therapist's guide, including the Parent Module (Parenting the Emotional Adolescent), and provide a space for questions and emotional support.
Changes in Anxiety and Depressive Symptoms as Assessed by RCADS-30
The Revised Child Anxiety and Depression Scale-30 (RCADS-30; Sandín et al., 2010) at pre, post-intervention and 3, 6 and 12 months follow-up. Range from 0 to 90. Symptoms of anxiety (panic disorder, social phobia, separation anxiety disorder, generalized anxiety disorder, and obsessive-compulsive disorder) and depressive disorders symptoms. Higher scores mean a worse outcome. Parents completed the "parent version" of the RCADS.
Time frame: Up to 12 months
Changes in Anxiety and Depressive Symptoms's Interference as Assessed by EIDAN
Depression and Anxiety Interference Scale for Children and Adolescents EIDAN (Espinosa et al., 2022) . It is a 10-item self-reported instrument that evaluates the interference of emotional symptoms in the adolescent's daily functioning in the previous weeks, in several contexts (school, family and with peers). The higher the score, the higher the level of interference. Assessed at pre, post-intervention and 3, 6 and 12 months follow-up. Range from 10 to 40. Parents completed the "parent version" of the EIDAN.
Time frame: Up to 12 months
Top Problems Measure
The adolescent version of the Top Problem Assessment (TPA) (Ehrenreich, 2018; adapted from Weisz et al., 2011) was used to enhance treatment outcomes and strengthen the therapeutic alliance. Adolescents were asked to write down the issues that concerned them the most and assess the severity of each problem by rating its impact on daily functioning on a scale from 0 ("not a problem at all") to 10 ("very, very much a problem"). Each adolescent selected between one and three problems and evaluated their severity at five time points: at the beginning of the program (session 3), mid-treatment (session 8), the final session (session 16), and during follow-ups at 3, 6 and 12 months.
Time frame: Up to 12 months

Higher scores in maladaptive regulation strategies (supression; rumination; distraction) and lower scores in adaptive strategies (attention/awareness/understanding; acceptance/tolerance; cognitive reappraisal; self-instructions) mean a worst outcome
