Initial Effectiveness Evaluation of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders for Homeless Women

Abstract

The purpose of this study is to evaluate the effectiveness of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders adapted for homeless women (UPHW). Eighty-one homeless women participated in this single-blinded quasi-experimental clinical trial, involving up to 12 sessions of group treatment, and 3-and 6-month follow-ups. The participants received either immediate treatment with the UPHW ( n = 46) or delayed treatment, following a 12-week wait-list control period (WLC; n = 35). Primary outcomes included depression and anxiety. Secondary measures comprised positive and negative affect, psychological well-being, health perception, and social support. The UPHW resulted in significant improvement on measures of anxiety, depression and negative affect. Improvements in anxiety and depression were maintained over a 3-month follow-up period, but not at 6-month. The reliability of the clinical changes showed significant differences between UPHW and WLC for depression. Moreover, the inter-session assessment in the UPHW group showed a linear trend reduction for depression and anxiety scores along the 12 sessions. The clinical implications on the UPHW in social settings are also discussed.
