The aim of the present study was to examine the efficacy of the program Learn to Manage your Emotions [Aprende a Manejar tus Emociones] (AMtE), a self-applied transdiagnostic internet-delivered program based on the Spanish version of the UP-A. This is the first transdiagnostic internet-based program designed for the treatment of emotional disorders in adolescents. Method A sample of Spanish adolescents with a primary diagnosis of an anxiety and/or depressive disorder (n = 58; age range = 12–18 years; 78.3% girls; 90% Caucasian) were randomly allocated to receive AMtE (n = 28) or the UP-A via videocall (n = 30). Pre-treatment, post-treatment and 3-month follow-up data were collected using self-reports and clinician-rated measures of anxiety, depression, positive and negative affect, anxiety sensitivity and emotional avoidance. Results Based on generalized estimating equations (GEE) models, both intervention programs were effective in significantly reducing self-reported anxiety and depressive disorder symptoms and clinician-rated severity of anxiety and depression, as well as self-reported transdiagnostic outcome variables. Conclusions Data provide empirical support for the efficacy of AMtE as a transdiagnostic online CBT treatment for anxiety and depressive disorders in adolescents. No marked nor consistent differences were observed between the UP-A and AMtE, highlighting the potential usefulness of the online self-administered AMtE program.eninfo:eu-repo/semantics/openAccess61 Psicología::6111 Personalidad61 Psicología::6105 Evaluación y diagnóstico en psicologíaartículoadolescentsonline CBTtransdiagnosticanxiety disorderdepressive disorder
