INTRODUCTION: The future of psychotherapy relies on the dialog with the basic science, being the identification of psychotherapeutifc biomarkers of efficacy a core necessity. @entity299 ( @entity299 ) is one of the most studied psychophysiological parameters in @entity148 . METHODS: To investigate the impact of cognitive behavior therapy (CBT) on the @entity299 of @entity1 with @entity148 , we conducted a meta-analysis and systematic review. Electronic searches were conducted in the ISI/Web of Knowledge, PsychINFO and PubMed/MEDLINE for studies which evaluated @entity299 at least once before and after CBT. Keywords related to @entity148 , @entity299 and CBT were used in the search. RESULTS: 474 studies, of which 47 were selected for the systematic review and 8 for the meta-analysis, were identified. The results provide evidence that CBT significantly decreases the @entity299 of @entity1005 @entity1 . In @entity913 , @entity3119 and @entity14469 , the results point in the same direction, although it is still early to attribute the decrease in @entity299 to CBT. In @entity6542 , traditional exposure therapy showed greater effect size than exposure with distractors or without psycho-education. LIMITATIONS: Most of the randomized trials have not been conducted in accordance with rigorous methodological quality criteria. CONCLUSIONS: Standardization in the methods used and in treatment protocols, as well as investigations in groups of @entity1 with low physiological reactivity, are necessary in order to reach better conclusions. Notwithstanding these limitations, @entity299 is beginning to emerge as a potential biomarker of efficacy in @entity148 .
