This article provides an empirically derived description of social pho
bia, including onset, prevalence, comorbidity, and issues of different
ial diagnosis. Assessment and behavioral treatment strategies for soci
al phobia are reviewed. It was not until the past few years that struc
tured clinical interviews and self-report inventories have been develo
ped with adequate reliability and validity to specifically assess soci
al phobia. Thus much of the treatment outcome research is confounded w
ith heterogeneous samples that make generalization of results difficul
t to interpret. Heterogeneity of samples, lack of controlled compariso
ns with adequate statistical power to detect treatment differences, an
d inconsistent findings do not permit the drawing of any definitive co
nclusions concerning the efficacy of behavioral treatment procedures a
t this time. More treatment comparison studies for social phobia need
to be performed using structured clinical interviews and standardized
assessment devices specific for use with social phobia. Pre hoc power
analyses should be performed to determine the number of subjects deeme
d adequate to detect differences when performing comparison studies. A
ssessment and treatment of social phobia with children is conspicuousl
y nonexistent. Assessment and treatment procedures for social phobia n
eed to be developed and standardized with children.
