ARRIGONI, Flavia; MARCHENA-CONSEJERO, Esperanza  and  NAVARRO-GUZMAN, José I.. Application and evaluation of the efficacy of the unified transdiagnostic protocol with spanish college students. Rev. Costarric. Psic [online]. 2021, vol.40, n.2, pp.149-169. ISSN 1659-2913.

This study presents the results of the application of the Unified Transdiagnostic Protocol Treatment of Emotional Disorders in a group format in a non-clinical context, with university students who have asked for therapy at the University Psychological Services. The standardized eight modules-UP was implemented and it was administered in twelve group sessions. Synchronous online weekly and 90-minute long sessions were carried out. UP is an evidence-based cognitive behavioral intervention program to address a wide range of emotional disorders. The general target was to examine the efficacy of UP for the Transdiagnostic Treatment of Emotional Disorders in an online group format. The specific targets were: (a) to increase quality of life, optimism and positive affect; and (b) to reduce depressive and anxious symptoms, negative affect, ruminant behaviors, psychological distress and experiential avoidance. This study was carried out with a quantitative, exploratory, descriptive and interactive approach. A quasi-experimental design, pre- and posttest for paired samples was used. Instruments: OASIS, ODSIS, QLI-Sp, COP, PANAS, RRS, CORE-OM, BEAQ, ad hoc socio-demographic file and Opinion Scale. A total of 9 students voluntarily participated in the study (Mean age = 21.11 years). After the intervention, statistically significant diffe- rences were found between the pre- and posttest measurements in negative affect (t = 3.250; p < .012) and in the CORE OM´ Risk Scale (t = 2.401; p < .043). The UP application in a group format with students that asked for therapy has proven to be effective in a non-clinical context, participants have shown progress in the treatment as well as in some psychological areas.
