Participants will be randomly allocated to one of four parallel experimental arms, within a 2X2 factorial design in which two interventions (tDCS and CBT-UP) will be delivered, and assessed according to two levels (e.g., intervention vs. no intervention). Each study participant will assigned to one factor level. Four intervention groups are defined active tDCS + CBT-UP sham tDCS + CBT-UP active tDCS + Psychoeducation sham tDCS + Psychoeducation The four arms allow to experimentally control the two active therapeutic interventions: active tDCS and CBT-UP. Sham tDCS is the control for active tDCS and psychoeducation is the control condition for CBT-UP. The intervention will last for 15 weeks, and all groups will comply with the same intervention structure according to the examination plan established in the protocol: week 1-2: 1 CBT-UP session/week week 3-4: 5 tDCS sessions and 1 CBT-UP session/week week 5-8: 2 tDCS sessions and 1 CBT-UP session/week week 9-14: 1 tDCS session and 1 CBT-UP session/week week 15: 1 CBT-UP session The treatment will consist of 26 transcranial direct current stimulation sessions, each lasting 20 minutes, with a current intensity of 2 mA, the cathode placed over the right dorsolateral prefrontal cortex and the anode placed over the left deltoid muscle. tDCS will be combined with cognitive-behavioral therapy, in particular following the unified protocol for transdiagnostic treatment of emotional disorders (Barlow et al. 2018). Safety: No serious adverse effects are expected with conventional tDCS protocols in humans (?40 min, ?4 mA; conclusions from a meta-analysis observing >33200 sessions, >1000 subjects with repeated sessions; Bikson et al., 2016). Plans for treatment or care after the subject has ended his/her participation in the trial: Patients will be recommended and offered the best treatment as evidenced by the trial results. For patients that already completed that intervention further standard psychological/psychiatric treatment will be recommended according to patients' status.
