Visit	QMI, men (mean)	QMI, women (mean)	EPDS, men (mean)	EPDS, women (mean)	Correlation with EPDS
t0	41.2	41.8	3.11	4.51	M: r =  − 0.361, p < 0.001 F: r =  − 0.313, p = 0.006
t1	40.5	39.8	3.14	5.31	M: r =  − 0.265, p = 0.026 F: n.s
t2	40.2	30.8	3.11	4.18	M: r =  − 0.265, p = 0.031 F: n.s
t3	38.6	36.6	2.88	4.62	M: r =  − 0.530, p < 0.001 F: r =  − 0.395, p = 0.004

The sum scores of QMI and EPDS were correlated in men and women in all study visits (t0 = pregnancy, t1 = 3 months postpartum, t2 = 6 months postpartum, t3 = 12 months postpartum). Spearman rho correlation was measured, level of significance was set at p ≤ 0.05

QMI = quality of marriage index; EPDS = Edinburgh postnatal depression scale; M = male, F = female
