title: Social phobia and avoidant personality disorder: are they separate diagnostic entities or do they reflect a spectrum of social anxiety?
abstract: The Axis I disorder social phobia and the Axis II disorder avoidant personality disorder were first introduced in the DSM nomenclature in 1980. Since then a major nosological theme in research has concerned whether or not social phobia and avoidant personality disorder represent distinct clinical categories. Our main aim was to summarize both the current situation regarding this conceptual debate, as well as what we still do not know. In the present review we describe the evolution of these disorders as they have been addressed over time, from their introduction in the DSM-III system to their current descriptions in the DSM-IV. Thereafter, earlier empirical literature concerning this conceptual debate is evaluated, with the main focus on comorbidity between social phobia and avoidant personality disorder. The PsycINFO and PubMed electronic databases were searched for studies, and complementary searches of references in articles and books were conducted. To conclude, the studies summarized provide support for the view that social phobia and avoidant personality disorder are more than arbitrary cutoffs along a continuum of social anxiety.
