Development trajectories of marital satisfaction and postpartum depression: a longitudinal study

Area of Science:

• Reproductive Health
• Mental Health
• Sociology

Background:

• Postpartum depression (PPD) is a significant public health concern.
• Marital satisfaction is a crucial factor in maternal well-being.
• Understanding the dynamic interplay between marital satisfaction and PPD is essential for effective interventions.

Purpose of the Study:

• To investigate the developmental trajectories of marital satisfaction and depressive symptoms in early postpartum.
• To examine the longitudinal predictive relationship and directionality between marital satisfaction and PPD.
• To explore the moderating effects of demographic and obstetric factors on this relationship.

Main Methods:

• Longitudinal study of 238 postpartum women assessed at 1, 6, and 12 weeks postpartum.
• Utilized Marital Satisfaction Scale and Edinburgh Postnatal Depression Scale.
• Employed Latent Growth Models and Cross-Lagged Panel Model for data analysis.

Main Results:

• Marital satisfaction linearly declined, while depressive symptoms linearly increased postpartum.
• Marital satisfaction significantly predicted lower PPD, but not vice versa (unidirectional relationship).
• The protective effect of marital satisfaction was stronger for unemployed women, those with low income, and after cesarean section.

Conclusions:

• Marital satisfaction is a key protective factor against PPD, influenced by socioeconomic and health factors.
• Integrating marital relationship assessment into postpartum care is recommended.
• Findings support targeted, couple-centered prevention strategies for high-risk populations.
