Social anxiety disorder (SAD) is a widespread condition characterized by a persistent fear of social situations and interactions. The DSM-5-TR identifies one primary subtype, “performance-only” SAD, which pertains to individuals who experience significant anxiety only during public performances, while feeling comfortable in other social contexts. This classification has sparked discussions about the need for a more nuanced understanding of social anxiety, as it may not capture the full spectrum of experiences.

Research suggests the inclusion of additional subtypes, such as generalized social anxiety, interaction anxiety, stranger-authority anxiety, and anxiety related to being observed during routine tasks. These distinctions could help illuminate specific fears and lead to more tailored treatments. Historically, social anxiety has been divided into generalized and nongeneralized types. Generalized social anxiety involves pervasive anxiety across various situations, often rooted in a fear of negative evaluation, while nongeneralized social anxiety appears in specific contexts, like job interviews or conversations with strangers.
The distinction between performance anxiety and social interaction anxiety adds complexity, as performance anxiety can arise in any situation where individuals feel observed, while social interaction anxiety encompasses a broader fear of socializing. A 2017 study found that many individuals exhibit overlapping fears, suggesting a spectrum of social anxiety rather than rigid categories.
The ongoing debate about the classification of social anxiety highlights the challenge of providing solid diagnoses. Researchers and clinicians must continue to explore these complexities to develop more precise diagnostic criteria and effective therapeutic approaches. Recognizing that social anxiety exists on a spectrum can enhance both academic understanding and therapeutic effectiveness, ultimately benefiting those affected by the disorder.
