Unified Protocol for Emotional Disorders: HiTOP-PRO Trial

This randomised, parallel-group clinical trial evaluates the effects of the Unified Protocol (UP), a transdiagnostic cognitive-behavioural psychotherapy, on dimensional symptom outcomes aligned with the Hierarchical Taxonomy of Psychopathology (HiTOP) and on related temperamental/personality traits in adults with emotional disorders. Participants are randomly assigned (1:1:1) to UP, treatment as usual (TAU), or a waitlist (WL). Outcomes are assessed at baseline and after approximately 14 weeks. A planned follow-up assessment approximately 3 months after treatment completion is collected in the UP arm only.

Virtual Reality Exposure Therapy for Obsessive-Compulsive Disorder: Outpatients Trial

The aim of this study is to evaluate the efficacy of virtual reality exposure therapy (VRET) as a treatment for obsessive-compulsive disorder (OCD). This study focuses on patients receiving treatment in outpatient psychiatry or clinical psychology settings, utilizing a within-subject design for comparison. Patients first complete informed consent and baseline questionnaires and are placed on a waiting list for five weeks. After this period, they are reassigned to the active (experimental) group, which will receive five sessions of exposure therapy in virtual reality over a subsequent five-week period. The treatment effect will be evaluated using pre/post assessments, as well as monitoring adherence to exposure and response prevention assignments.
