We aimed to determine their efficacy on mild/moderate emotional disorders compared with treatment as usual (TAU) based on pharmacological interventions. Method: This study was a single-blinded randomized controlled trial with parallel design of three groups. Patients (N = 102) were assigned to brief individual psychotherapy (n = 34), brief group psychotherapy (n = 34) or TAU (n = 34). Participants were assessed before and after the interventions with the following measures: PHQ-15, PHQ-9, PHQ-PD, GAD-7, STAI, BDI-II, BSI-18, and SCID. We conducted per protocol and intention-to-treat analyses. Results: Brief psychotherapies were more effective than TAU for the reduction of emotional disorders symptoms and diagnoses with moderate/high effect sizes. TAU was only effective in reducing depressive symptoms. Conclusions: Brief transdiagnostic psychotherapies might be the treatment of choice for mild/moderate emotional disorders and they seem suitable to be implemented within health care systems.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Brief psychotherapiesEmotional disordersExperiment.Randomized controlled trialTransdiagnostic treatmentresearch article33363586open access10.1016/j.ijchp.2020.11.0022174-0852PMC7753034https://doi.org/10.1016/j.ijchp.2020.11.002https://pmc.ncbi.nlm.nih.gov/articles/PMC7753034/pdf
