Abstract:
OBJECTIVE Various approaches to cognitve behavioral therapy (CBT) have been shown to be effective for
social anxiety disorder. For psychodynamic therapy .evidence for efficacy in this disorder is scant. The authors
tested the efficacy of psychodynamic therapy and CBT in social anxiety disorder in a multicenter randomized
controlled trial.
METHOD In an outpatien setting, 495 patiens with social anxiety disorder were randomly assigned
to manual-guided CBT (209), manual-guided psychodynamic therapy (N=207),or a waiting list
condition (N=79). Assessments were made at baseline and at the end of treatment. Primary outcome
measures were rates of remission and response,basede on the Liebowitz Social Anxiety Scale applied
by raters blind to group as signment. Several secondary measures were assessed as well.
RESULT Remission rates in the CBT, psychodynamic therappy, and waiting list groups were 36%,26% ,
and 9%,respectively. Response rates were 60%, 52% and 15%,respectively. CBT and psychodynamic
therapy were significantly superior to psychodynamic therapy for remmission but not for response. Between
group effect sizes for remission and response were small. Secondary outcome measures showed significant
differences in favor of CBT for measures of social phobia and interpersonal problems, but not for depression.
CONCLUSION CBT and psychodynamic therapy were both efficacious in treating social anxiety disorder, but
there were significant differences in faver or CBT. For CBT, the response rate was comparable to rates reported
in Swedish and German studies in recent years. For psychodynamic therapy, the response rate was comparable
to rates reported for pharmacotherapy and cognitive-behaviroal group therapy.
