Multiple mediation effect of coping styles and self-esteem in the relationship between spousal support and pregnancy stress of married immigrant pregnant women

Background: The purpose of this study was to identify the total, direct, and indirect influence of spousal support on pregnancy stress among married immigrant pregnant women. The study aimed to determine the relative magnitudes of specific mediating effects of coping styles and self-esteem.Method: A cross-sectional correlational survey was conducted in Gwangju with 206 married immigrant pregnant women. Data were collected from September 7 to November 7 in 2019. A self-report questionnaire was used to measure spousal support, pregnancy stress, coping styles, and self-esteem. The study employed a linear multiple regression analysis to examine the potential multi-mediating effects. The effect size was set at 0.15, the significance level at 0.05, and the power at 0.95. Through the analysis, the researchers explored the mediating mechanisms among the variables and identified the presence of multi-mediating effects.Results: The effect sizes (b) and statistical significance (p) for the predictors were as follows: problem-focused coping (b = 0.13, p = 0.001), emotion-focused coping (b = 0.11, p = 0.004), and self-esteem (b = 0.10, p < 0.001). Emotion-focused coping (b = 0.26, p = 0.001) and self-esteem (b = -0.20, p = 0.035) had a significant impact on pregnancy stress. The total effect of spousal support on pregnancy stress was significant at -0.25 (p < 0.001), and the direct effect was also significant at -0.26 (p < 0.001). We observed significant mediating effects for emotion-focused coping and self-esteem.Conclusions: As a result of this study, the self-esteem of married immigrant pregnant women can have a protective effect by preventing the aggravation of pregnancy stress in the relationship between spousal support and pregnancy stress. Meanwhile, the emotion-focused coping style can balance out the effect of self-esteem. Therefore, in order to alleviate the stress of pregnancy for women, it is necessary to provide intervention to help improve self-esteem with spousal support. In addition, nursing professionals should help them use appropriate coping styles.
