The clinical field has increased its use of a dimensional approach when looking at psychological symptoms rather than a sole categorical method of yes or no to all criteria met (e.g., use of the DSM-V criteria). This suggests that symptoms of anxiety and worry that are used to categorize GAD are found in other emotional diagnoses, and individuals express symptoms in different variations and levels. An increased liking for dimensional approaches is a potential factor contributing to an increased interest in studying GAD specifically.
