Serial mediation effects of social support and antepartum depression on the relationship between fetal attachment and anxiety in high-risk pregnant couples of South Korea

Purpose: This study examined the direct effects of fetal attachment, social support, and antepartum depression on anxiety in pregnant women with high-risk pregnancy-related conditions and their husbands. Furthermore, it aimed to explore the serial mediation effects of social support and antepartum depression in the relationship between fetal attachment and anxiety. Methods: A survey-based study was conducted among pregnant women diagnosed with high-risk pregnancy conditions at 24-32 weeks and their husbands, recruited from a pregnant women's online community between January 20, 2021 and July 20, 2022. Data were collected from 294 individuals (147 couples) using self-report questionnaires. Correlations between variables were analyzed using the IBM SPSS software ver. 26.0 (IBM Corp.), and the mediation effects were assessed using the PROCESS macro, model 6. Results: In the maternal model, maternal-fetal attachment directly affected anxiety (p=.005), with antepartum depression partially mediating this relationship (95% confidence interval [CI], -0.26 to -0.01). In the paternal model, paternal-fetal attachment had no direct effect on anxiety (p=.458). However, social support and antepartum depression fully mediated the relationship between paternal-fetal attachment and anxiety (95% CI, -0.14 to -0.03). Conclusion: The findings indicate that social support in the relationship between fetal attachment and depression in high-risk pregnant women and their partners can have direct or indirect effects on the negative emotions of high-risk pregnant couples. It is necessary to assess the level of anxiety in couples experiencing high-risk pregnancies and provide comprehensive nursing interventions that address fetal attachment, social support, and antepartum depression in order to reduce anxiety.
