Actor-partner interdependence mediation model (APIMeM) with chronic extradyadic minor stress as predictor, chronic intradyadic minor stress as mediator, and depressive symptoms as outcome. R1–R4 = residuals of the mediators and outcomes, A(W) = actor effect of women, A(M) = actor effect of men, P(W) = partner effect of women, P(M) = partner effect of men. The model also included confounders and autoregressive paths (not shown in figure).

Flowchart of retention rates, attrition, and exclusion criteria.
The present sample comprised women and men who completed T4 questionnaires until March 10, 2023 (prospective data collection ongoing). T1 = during pregnancy. T4 = 2 years after birth. T5 = 3 years after birth. MSQ-C = Multidimensional Stress Questionnaire for Couples. a Participants separated from the partner with whom they were in a couple relationship at T1. b Within 2 years ± 2 months after birth. c As only the whole couple was considered at T4, participants were excluded if their partner did not complete T4 questionnaires.

Standardized coefficients (Δ) of direct effects in the actor-partner interdependence mediation model (APIMeM) with included confounder (academic degree).
APIMeM with chronic extradyadic minor stress as predictor, chronic intradyadic minor stress as mediator, and depressive symptoms as outcome. R1–R4 = residuals of the mediators and outcomes. The model also included the confounder academic degree (not shown in figure). Solid lines indicate significant paths (p < .05). Dashed lines indicate non-significant paths. χ2 = 8.948 (df = 10, p = .537). RMSEA = 0.000. CFI = 1.000. TLI = 1.000.
