Results on affect inventories as a function of COMT genotype. (a) No significant difference between Met allele carriers and the Val/Val group on STAI, state anxiety t(76) = −1.00, p = .32, trait anxiety t(76) = −1.33, p = .19. (b) Significantly lower scores on acute mood disturbance t(76) = −2.70, p = .009, and ongoing mood disturbance t(76) = −2.34, p = .02 for Met allele carriers measured via the POMS. (c) A significant increase in depressive symptomatology t(76) = −2.95, p = .004, for Val/Val genotypes (CES‐D). (d) Perceived stress (PSS) was significantly lower in Met allele carriers than the Val/Val group t(76) = −2.63, p = .01. COMT, catechol‐O‐methyltransferase; POMS, Profile of Mood States
