Next we investigated whether the rs7632287 genotype in women was related to their partners’ perceptions of marital quality within the TOSS sample. This analysis was intended to further identify potential effects of the women’s genotype upon their current relationships. For this purpose, we used the four subscales (Dyadic Consensus, Dyadic Satisfaction, Dyadic Cohesion and Affectional Expression) from the Dyadic Adjustment Scale (52), commonly used to measure quality of marital relationships. The correlations between the DAS subscales in men and PBS scores in women ranged from r=0.37 to r=0.42. In line with our hypothesis marital quality, as assessed by the husbands, was associated with the rs7632287 genotype of their wives. Men married to women carrying the A-allele reported significantly lower scores on the Dyadic Consensus (measuring agreement on matters important to dyadic functioning) subscale than did men married to women not carrying this allele (d=0.13) (Table 4b).
