Depression with or without comorbid social anxiety: Is attachment the culprit?

Numerous cross-sectional studies have documented high rates of comorbidity between social anxiety disorder (SAD) and major depressive disorder (MDD), as well as increased chronicity and impairment associated with it (Kessler et al., 1999; Nelson et al., 2000; Ohayon and Schatzberg, 2010). Several prospective studies have established that, in most cases, SAD precedes MDD and increases the risk for MDD in all ages (Beesdo, 2007; Stein, 2006; Stein et al., 2001). In particular, in the presence of SAD, MDD has a more malignant course, increased duration of episodes, increased suicidality, and additional comorbidity (Dalrymple and Zimmerman, 2011; Nelson et al., 2000; Ohayon and Schatzberg, 2010).
