“…Moreover, because research on postpartum depression points to variability in the onset, intensity, and course of development of postpartum depressive symptoms across individuals [ 29 ], we wanted to explore and highlight the idiosyncratic relations independently between the variables in our study at each time point after the birth. For these two reasons, we produced separate independent models for each time point (see also [ 19 , 30 , 31 ]). Due to the dyadic nature of our data, however, we did analyze them using two-intercept models, where both partners were included, to account for couple interdependence and for any dyadic variability, and to allow for the consideration of estimating effects for male and female participants both simultaneously and separately (see [ 32 , 33 ]).…”
