BACKGROUND Fathers' depression is an understudied subject, and the increasing participation of fathers on the care of their children, this is an issue of great importance. This study aimed to determine the relationship of paternal postpartum depression with prenatal and postpartum depression of mothers and their marital satisfaction. METHODS This longitudinal study was conducted among 352 expecting couples in 28-40 weeks of pregnancy and 6-8 weeks after delivery from April to September 2019. Eligible participants were selected from primary health care centers in northern Iran using a two-stage sampling method. Socio-demographic information, Edinburgh Postpartum Depression Scale, and ENRICH Couple Scale were used for data collection. The primary basis of data analysis was cross-lagged structural equation modeling to explore the underlying mechanism for paternal postpartum depression. RESULTS The results showed that a) maternal prenatal depression indirectly (βstand= 0.32, p =0.004); b) maternal postpartum depression directly (βstand = 0.56, p <0.001); c) paternal prenatal depression indirectly (βstand= 0.11, p =0.028) were associated with paternal postpartum depression. Also, marital satisfaction directly (βstand= -0.19, p =0.002) and indirectly (βstand= -0.11, p =0.007) had a relationship to paternal postpartum depression. LIMITATIONS Culturally-sensitive measures of marital satisfaction, especially in conservative context of developing countries, along with self-reported data of psychological problems may lead to under-reported findings. CONCLUSION The major contribution of marital satisfaction and maternal depression during prenatal period on the paternal postpartum depression, emphasizes on the prenatal period as the ideal time for fathers' mental health improvement.
