Group Version of the UP-A in a Spanish Day Hospital for Adolescents.

The UP-A (Ehrenreich-May et al., 2018, 2020, 2022) is a transdiagnostic intervention with eight modules targeting neuroticism. It improves emotion regulation and reduces avoidance, with summaries after each module and a Parent Module (P). The intervention is a group adaptation of the Spanish version of UP-A that consists of 16 weekly sessions, each lasting 60 to 90 minutes, held in person at a Day Hospital within the Spanish public healthcare system. Due to the complexity of the setting, parent sessions are not viable. However, parents receive summaries of the modules covered with the adolescents, as well as the Parent Module (Parenting the Emotional Adolescent), to support their understanding of the treatment content.
