Social Anxiety Disorder can affect about 7.1% of adults in the U.S. in the past year and about 13.0% over a lifetime. It’s marked by intense fear of social scrutiny where negative judgment may occur, with common physical symptoms like blushing, sweating, trembling, and a rapid heartbeat—followed by avoidance. This page walks through how genetics and family history, childhood maltreatment, and overprotective parenting shape risk, and how SAD often co-occurs with depression and alcohol use problems. It also covers outcomes such as higher suicide attempt risk and what treatments can realistically help.
Key Takeaways

- First-degree relatives of SAD patients have 2-6x higher risk
- Childhood maltreatment increases SAD risk by 2.5-fold

- Alcohol use disorder comorbidity rate 20-40% in SAD patients
- Suicide attempt risk 2.7x higher in SAD vs general population
- Lifetime prevalence of Social Anxiety Disorder (SAD) in the United States among adults aged 18 and older is 13.0%
- Past year prevalence of SAD in US adults is 7.1%, affecting approximately 15 million adults
- Globally, the 12-month prevalence of SAD is around 4-13%, with variations by country
