Sixty-three adolescents with social phobia and 43 with no psychiatric disorders were compared across a number of clinical variables. In addition to clinically impairing social fear, adolescents with social phobia had significantly higher levels of loneliness, dysphoria, general emotional over-responsiveness and more internalizing behaviors than normal controls and 57.1% of socially phobic adolescents had a second, concurrent diagnosis, 75% of which were other anxiety disorders. In addition, adolescents with social phobia were significantly less socially skilled. Though similar in some respects to childhood social phobia, adolescent social phobia has a unique clinical presentation. The importance of developmental differences on the development of age-appropriate interventions is discussed.
