There was a significant main effect of group (but no significant main effect of BDNF genotype or interaction between group and BDNF genotype) on the anxiety (F = 10.975, R2 = 0.068, P = 0.001), depression (F = 8.875, R2 = 0.056, P = 0.003), and hypochondriasis (F = 27.314, R2 = 0.154, P<0.001) dimensions of Basic Personality Inventory.
