DISORDERS
This is the protocol of a parallel-group, controlled, randomized trial, with a pre-post and repeated follow-up measures intergroup design. This trial is framed in the superiority framework.A two-arm trial is going to be carried out. For this reason, a waiting list has been chosen as a comparator. Participants with low to moderate anxiety/depressive symptoms will be randomly assigned to Group 1: Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) intervention, or Group 2: Wait-List Control group.The assessment will be conducted at three-time points for Group 1: an initial assessment before being randomized (pretreatment; T0), at the end of the intervention (post-treatment; T1), and 3 months after the completion of the intervention (T2). Group 2 will be assessed on T0 and T1. T2 would not be measured in this group since after T1 they will start treatment.CONSORT patient’s flowchart is presented in Fig. CONSORT flow diagram
