	Crude coefficient (95% CI)	Adjusted coefficient (95% CI)†
Relationship quality ‡
Overall	3.49 (2.68, 4.30)**	2.49 (1.48, 3.50)**
Subscales:
Emotional support	2.49 (1.75, 3.22)**	1.53 (0.68, 2.38)**
Conflict/demand‡	−2.59 (−3.27, −1.90)**	−1.48 (−2.31, −0.66)**
Instrumental support	2.59 (1.90, 3.28)**	1.74 (0.98, 2.51)**
Social support
Overall	2.12 (1.46, 2.78)**	1.07 (0.31, 1.83)*
Subscales:
Support from family	1.75 (1.08, 2.43)**	0.50 (−0.26, 1.27)
Support from friends	1.64 (1.12, 2.18)**	0.98 (0.40, 1.57)**

^†Models were adjusted for treatment group, monthly household income, preterm birth, exposure to intimate partner violence (IPV) at postpartum, and postpartum depressive symptoms (PPD).

^‡High scores in conflict/demand subscale indicates high levels of conflict or demand. In the overall score, conflict/demand subscale was reversely scored. High scores in overall relationship quality indicate good relationship with spouse.

Note: Romano-Wolf stepdown p-values was calculated to take account for multiple hypothesis testing.

^*adjusted p<0.05

^**adjusted p<0.01

^***adjusted p<0.001.
