| Abstract: | Exposure-based therapies are efficacious treatments for social anxiety disorder (i.e., Gould et al., 1997). Much of the theory behind these treatments is derived from Foa and colleagues' (Foa, Huppert, & Cahill, 2005; Foa & Kozak, 1986) work on emotional processing. However, there has been little research examining individual differences in emotional processing patterns within and between treatment sessions among clients with social anxiety disorder. This study utilized longitudinal data analytic methods to examine changes in subjective anxiety during the first 3 exposure sessions in group and individual cognitive-behavioral therapy for social anxiety disorder. The results of this study provide preliminary evidence that, although anxiety generally decreases across exposures, some individuals experience considerable fluctuations in anxiety during a single exposure. Although anxiety during the first exposure was not significantly related to outcome, the relationship between anxiety during exposure and outcome became stronger during subsequent exposures. Overall, this study highlights the need to conduct more fine-grained analyses to better understand the mechanisms underlying exposure-based therapies for social anxiety disorder. |
