The Genetic and Environmental Etiology of Social Phobia in Youth and the Etiological Overlap Between Shyness, Extraversion, and Social Phobia Público

Abstract

This study examined the genetic and environmental etiology of social phobia and the etiological overlap between social phobia, shyness, and extraversion in youth. We used a representative sample of twins (N = 874 twin pairs) ages 4 to 19 whose parents rated them on measures of psychopathology, temperament, and personality. Results of the univariate behavior genetic analyses suggested significant additive genetic and nonshared environmental influences on social phobia. Bivariate genetic analyses indicated a moderate positive genetic and nonshared environmental correlation between shyness and social phobia. There was also a small negative genetic and environmental correlation between social phobia and extraversion and shyness and extraversion. Together, these results suggest that social phobia has genetic and unique environmental causes and may be etiologically related to shyness and extraversion.
