State of the Science: The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders

Before the development of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP), evidence-based treatment options for commonly co-occurring anxiety, mood, and related disorders consisted of numerous single-disorder protocols that shared many similarities, reflecting the overlap among these disorders themselves. The UP distilled common elements of cognitive behavioral protocols into a unified intervention directly targeting core temperamental features underlying these disorders of emotion, namely neuroticism and associated emotion dysregulation. The UP has since become a leading “transdiagnostic” treatment for emotional disorders, which is now available in several formats (e.g., individual, group, digital) and has accumulated a strong evidence base, leading to international implementation. There is now also research evidence that the UP can be flexibly applied to a range of clinical presentations, including borderline personality disorder, trauma- and stressor-related disorders, eating disorders, alcohol use disorder, and comorbid chronic physical health conditions. Yet additional research is needed to evaluate the UP in routine clinical settings, with more heterogeneous patient populations, and under circumstances that mirror actual clinical practice. Thus, we must also continue to explore the benefits of large-scale UP training initiatives and implementation in major healthcare systems.
