Abstract：
:Emotion regulation difficulties have been involved in multiple forms of psychopathology and may represent an important focus for current efforts to understand the biological mechanisms underlying transdiagnostic symptoms. The present study investigated a gene-environment interaction (G × E) in reappraisal, a form of emotion regulation that has been extensively linked to psychopathology. In light of recent meta-analytic evidence of its consistent role in depression and anxiety disorders, this study focused on the Val66Met (rs6265) single-nucleotide polymorphism in the brain-derived neurotrophic factor (BDNF) gene and examined its moderator role in the relation between childhood trauma and reappraisal. A sample of N = 266 participants were genotyped for BDNF Val66Met, filled in a self-report measure of childhood trauma, and underwent a cognitive task designed to assess reappraisal ability. The results indicated that, as expected, BDNF Val66Met was a significant moderator in the relation between childhood trauma and reappraisal. There was a negative relation between the number of childhood traumatic events and reappraisal ability in BDNF Met carriers, but not Val homozygotes. This finding suggests that BDNF Val66Met contributes to susceptibility to childhood stress, with long term impact on emotion regulation.
