“…SAD is a relatively common disorder in Western cultures, with reported lifetime prevalence ranging between 4.4% in Europe (Ohayon & Schatzberg, 2010) and 12.1% in the United States (Kessler, Berglund, et al, 2005;Ruscio et al, 2008). The age of onset has been found to be approximately 13 years (Kessler, Berglund, et al, 2005;McEvoy, Grove, & Slade, 2011), and its impact can be severe; it has been associated with increased risk for subsequent depression (Beesdo et al, 2007); co-morbid anxiety, mood, and impulse control disorders (Kessler, Chiu, Demler, & Walters, 2005); alcohol dependence (Kessler, Chiu, et al, 2005;Schneier et al, 2010); and significant problems in social and occupational functioning (McKnight, Monfort, Kashdan, Blalock, & Calton, 2016).…”
