A preliminary investigation of the long-term outcome of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders.

OBJECTIVE The aim of this study is to conduct a preliminary examination of long-term outcomes on a broad range of affective disorder symptoms treated with a newly developed intervention: The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP). METHOD Maintenance of treatment gains at long-term follow-up (LTFU) were explored in patients (N=15, mean age=32.27; 60% female) who completed a clinical trial of the UP. RESULTS Treatment gains observed at 6-month follow-up (6MFU) on measures of clinical severity, general symptoms of depression and anxiety, and a measure of symptom interference in daily functioning were largely maintained 12months later (at an average of 18months posttreatment), and any significant changes from 6MFU to LTFU reflected small increases in symptoms that remained, on average, in the subclinical range. CONCLUSIONS These findings provide the first initial support for the durability of broad treatment gains following transdiagnostic treatment.
