“…Further, SAD is highly comorbid with a number of psychological disorders, including, but not limited to other anxiety disorders (e.g., generalized anxiety disorder, panic disorder), depressive disorders (e.g., major depressive disorder; MDD), substance use disorders (e.g., alcohol use disorder), and personality disorders (e.g., avoidant personality disorder, dependent personality disorder), which can further increase levels of functional impairment and worsen the clinical course of SAD (Bruce et al, 2005;Grant et al, 2005;Kessler, 2003;Mennin et al, 2000;Ohayon, & Schatzberg, 2010;Stein & Kean, 2000). Additionally, previous research has demonstrated an association between social anxiety and significant social and economic burden as a result of reduced work productivity and absenteeism, which is associated with reduced income and increased disability costs (Dams et al, 2017;Nardi, 2003Nardi, , 2005Patel et al, 2002;Stuhldreher et al, 2014).…”
