Based on common (transdiagnostic) principles of treatment (e.g., emotional exposure), these approaches have proliferated and demonstrated their efficacy in comparison to disorder-specific treatments. Although there are a few transdiagnostic approaches for children and adolescents, we could not find anyone targeting young people. For this reason, we propose the Identity-Based Transdiagnostic Therapy (IBTT) as a new treatment modality ideally created to address the challenge of improving the outcomes of psychotherapy for young adults with anxiety and/or depression. The IBTT is a psychological treatment for emotional disorders specifically designed for the youths in terms of their attitudes to treatment (attractiveness, engagement), and highly personalized to their construal of self and others. This project will allow testing the hypothesis that a novel brief psychotherapeutic intervention, IBTT, will be more efficacious in the treatment of the anxiety and/or depression of young adults than the well-established CBT-based Unified Protocol., conditionsModule conditions: Depression, conditions: Anxiety, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: The main study of this project proposal is a multi-center, single-blind, parallel-group randomized clinical trial (RCT) conducted in Catalonia (Spain)., primaryPurpose: TREATMENT, maskingInfo masking: SINGLE, whoMasked: INVESTIGATOR, enrollmentInfo count: 138, type: ESTIMATED, armsInterventionsModule interventions name: Identity-Based Transdiagnostic Therapy (IBTT), interventions name: Unified Protocol, outcomesModule primaryOutcomes measure: Depression, Anxiety and Stress Scales (DASS-21), secondaryOutcomes measure: Clinical Outcomes in Routine Evaluation-Short Form B (CORE-SFB), secondaryOutcomes measure: Mini International Neuropsychiatric Interview (MINI), secondaryOutcomes measure: Session Rating Scale 3.0 (SRS 3.0), secondaryOutcomes measure: Life Satisfaction Scale (LSS), secondaryOutcomes measure: Self-Concept Clarity Scale (SCCS), secondaryOutcomes measure: Rosenberg Self-Esteem Scale (RSES), secondaryOutcomes measure: Metacognition Self-Assessment Scale (MSAS), secondaryOutcomes measure: Problem definition form, secondaryOutcomes measure: Change Interview, secondaryOutcomes measure: Consumer Reports Effectiveness Scale (CRES-4), eligibilityModule sex: ALL, minimumAge: 16 Years, maximumAge: 29 Years, stdAges: CHILD, stdAges: ADULT, contactsLocationsModule locations facility: Badalona Serveis Assistencials, city: Badalona, zip: 08911, country: Spain, contacts name: Irene Alvarez, PhD, role: CONTACT, email: iatomas@bsa.cat, geoPoint lat: 41.45004, lon: 2.24741, locations facility: Associació Centre Higiene Mental Nou Barris, city: Barcelona, zip: 08042, country: Spain, contacts name: Giuseppina Rametti, PhD, role: CONTACT, email: giusi.rametti@csm9b.com, geoPoint lat: 41.38879, lon: 2.15899, hasResults: False
