Associations between dyadic coping, marital satisfaction, and prenatal depression symptoms among couples with gestational diabetes mellitus.

Aims/background: Coping with gestational diabetes mellitus (GDM) presents significant challenges for pregnant women and their partners, which may result in elevated prenatal depression symptoms. However, research has predominantly centred on pregnant women with GDM, with little involvement of their partners. To understand their dyadic interactions, it is imperative to involve GDM couples in the study. This study aims to examine the interplay between dyadic coping and prenatal depression symptoms among GDM couples and to explore the possible mediating role of marital satisfaction.

Design/method: A cross-sectional study was conducted in Guangzhou, China. A total of 400 couples completed the Dyadic Coping Inventory, Locke-Wallace Marital Adjustment Scale, Edinburgh Postnatal Depression Scale, and sociodemographic data sheet. The actor-partner interdependence mediation model was utilised for dyadic data analysis.

Results: Overall, 13.0% of pregnant women with GDM and 8.3% of partners experienced elevated prenatal depression symptoms. Dyadic coping was directly or indirectly related to their own and partners' prenatal depression symptoms in GDM couples, with marital satisfaction acting as a mediator. Specifically, positive dyadic coping was associated with lower prenatal depression symptoms, while negative dyadic coping exhibited an opposite relationship.

Conclusion: The prevalence of elevated prenatal depression symptoms was high in GDM couples. It is important to view pregnant women with GDM and their partners as a dyad of a transactional system in prenatal clinical care. Couple-centred interventions targeting to enhance positive dyadic coping and mitigate negative dyadic coping might be beneficial to prevent and alleviate prenatal depression symptoms.
