The increase in interest in GAD: Commentary on Asmundson & Asmundson

Abstract

Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders. It is associated with functional impairment and is unlikely to spontaneously remit. As identified by Asmundson and Asmundson (2018), published research studies on GAD have increased in number over the last decade. We propose that this is due to the high prevalence of the diagnosis and symptoms, interest in transdiagnostic processes, such as worry, increased interest in emotion dysregulation as a principle underlying diagnoses, and new methods of treating and disseminating treatment that may be particularly well suited to GAD. Despite the increase in research articles on GAD, GAD still remains one of the least studied anxiety disorders. We propose that this is due to the misconception that GAD does not lead to severe impairment, despite data showing otherwise. Future research should continue to examine the phenomenology, mechanisms, and treatment of GAD in order to better understand this common anxiety disorder.
