Full quote from NICE “Version for Professionals” :
Social anxiety disorder (previously known as ‘social phobia’) is one of the most common of the anxiety disorders. Estimates of lifetime prevalence vary but according to a US study, 12% of adults in the US will have social anxiety disorder at some point in their lives, compared with estimates of around 6% for generalised anxiety disorder (GAD), 5% for panic disorder, 7% for post-traumatic stress disorder (PTSD) and 2% for obsessive–compulsive disorder. There is a significant degree of comorbidity between social anxiety disorder and other mental health problems, most notably depression (19%), substance-use disorder (17%), GAD (5%), panic disorder (6%), and PTSD (3%).
Even on the stricter criteria that’s 1.59 MILLION adults in the UK this year.
The NICE full guidance goes further :
Twelve-month prevalence rates as high as 7% have been reported for social anxiety disorder (Kessler et al., 2005b). Using strict criteria and face-to-face interviews in the US, the lifetime and yearly prevalence figures are halved to 5% and 3%, respectively (Grant et al., 2005)
