Antepartum Anxiety, Dyadic Coping, and Stress Among Chinese Pregnant Couples: The Actor-Partner Interdependence Mediation Model

Introduction: Pregnancy can cause stress for couples, potentially leading to anxiety. However, most studies on antepartum anxiety focus on expectant mothers, ignoring the expectant fathers and the stress transmission between couples. We aim to examine the mediation of dyadic coping between antepartum anxiety and stress in expectant mothers and fathers. Design: We implemented a cross-sectional study in Guangzhou, China, from October 2023 to January 2024. Methods: Three-hundred and twenty-nine Chinese pregnant couples completed the Perceived Stress Scale, the Dyadic Coping Inventory, and the State–Trait Anxiety Inventory. The actor-partner interdependence mediation model was used for data analysis. Results: Expectant mothers experienced antepartum anxiety symptoms at a rate of 42.6%, while the rate for expectant fathers was 32.5%. Regarding the actor effects, stress was positively associated with antepartum anxiety in expectant mothers (β = 0.66, 95% confidence interval CI [0.56, 0.74]) and fathers (β = 0.58, 95% CI [0.42, 0.70]), with dyadic coping acting as a mediator (expectant mothers: β = 0.08, 95% CI [0.03, 0.14]; fathers: β = 0.11, 95% CI [0.04, 0.19]). Regarding the partner effects, maternal dyadic coping was positively associated with paternal stress (β = 0.10, 95% CI [0.01, 0.19]). Conclusion: The study highlights the interplay of stress, dyadic coping, and antepartum anxiety in expectant mothers and fathers, emphasizing the need to assess their antepartum anxiety and implement couple-centered interventions to enhance their psychological well-being during the first trimester of pregnancy. Clinical Relevance: This study highlights the importance of assessing antepartum anxiety in both expectant mothers and fathers, emphasizing the mediation of dyadic coping in reducing stress and anxiety. The findings support the integration of couple-centered mental health interventions into routine antepartum care to enhance psychological well-being during pregnancy.
