title: Changing core beliefs with trial-based cognitive therapy may improve quality of life in social phobia: a randomized study.
abstract: OBJECTIVE
  To determine whether there are differences in quality of life (QoL) improvement after treatment with the trial-based thought record (TBTR) versus conventional cognitive therapy (CCT) in patients with social anxiety disorder (SAD).
  
  
  METHODS
  A randomized trial comparing TBTR with a set of CCT techniques, which included the standard 7-column dysfunctional thought record (DTR) and the positive data log (PDL) in patients with SAD, generalized type.
  
  
  RESULTS
  Repeated measures analysis of variance (ANOVA) revealed a significant time effect in the general health, vitality, social functioning, and mental health domains of the Short Form 36. It also indicated significant treatment effects on the bodily pain, social functioning, role-emotional, and mental health domains, with higher scores in the TBTR group. One-way analysis of covariance (ANCOVA), using pretreatment values as covariates, showed that TBTR was associated with significantly better QoL post-treatment (bodily pain, social functioning and role-emotional) and at follow-up (role-emotional). A significant treatment effect on the role-emotional domain at 12-month follow-up denoted a sustained effect of TBTR relative to CCT.
  
  
  CONCLUSIONS
  This study provided preliminary evidence that TBTR is at least as effective as CCT in improving several domains of QoL in SAD, specifically when the standard 7-column DTR and the PDL are used.
