Efficacy of the unified protocol for transdiagnostic treatment of comorbid emotional disorders in patients with ultra high risk for psychosis: Results of a randomized controlled trial.

ABSTRACT

BACKGROUND: The most common reason for help-seeking in ultra-high risk (UHR) for psychosis patients is comorbid symptoms, mainly anxiety and depression. However, psychological interventions are mainly focused on subthreshold psychotic symptoms. There is a growing push to include transdiagnostic therapies in specialized intervention teams for psychosis in young people. The Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) has demonstrated efficacy in emotional disorders, and its application has recently expanded to other pathologies such as borderline personality disorder (BPD) and bipolar disorder (BD). METHODS: This pilot study was conducted with 36 patients with UHR for psychosis and symptoms of comorbid emotional disorders who were receiving treatment in an early intervention programme for psychosis. This is a randomised control trial (RCT) with two conditions treatment as usual (TAU) with the group and online application of the UP (UP+TAU) (n = 18) and TAU (n = 18). Evaluations were conducted at baseline, after treatment, and at the three-month follow-up. RESULTS: Comorbid anxiety and depression symptoms improved significantly in patients in the UP+TAU group compared to those in the TAU. Significant improvements in negative affect, emotional dysregulation, neuroticism, extraversion, functioning, and quality of life were also observed, and satisfaction with the intervention was high. CONCLUSIONS: UP may be an acceptable and effective intervention for the treatment of symptoms of comorbid emotional disorders in patients with UHR for psychosis. LIMITATIONS: The sample size was small, and further studies are needed to test this intervention with larger samples of patients with UHR for psychosis with emotional comorbidities.
