Path analysis of COVID-19 cognition, social support, and mental health of pregnant women with interventional prenatal diagnosis during the COVID-19 pandemic based on structural equation modeling

This study aims to investigate the relationship between Corona Virus Disease 2019 (COVID-19) cognition, social support, and mental health among pregnant women proposed for undergoing interventional prenatal diagnosis in Sichuan Province during the COVID-19 pandemic. A total of 2270 pregnant women (2232 valid) who were proposed to undergo interventional prenatal diagnosis at a tertiary hospital prenatal diagnosis center in Sichuan Province from January to December 2022 were selected by Convenience sampling and surveyed using a self-administered general information questionnaire, social support rating scale, mental health questionnaire (including: Self-Rating Anxiety Scale, Self-Rating Depression Scale), and self-administered COVID-19 cognition questionnaire. Structural equation modeling showed that social support negatively predicted anxiety (beta = -0.34, t = -14.98, P < .001) and negatively predicted depressive status (beta = -0.21, t = -9.57, P < .001); COVID-19 cognition negatively predicted anxiety (beta = -0.76, t = -5.34, P < .001) and depression (beta = -0.40, t = -2.99, P < .01); anxiety positively predicted anxiety (beta = 0.73, t = 37.34, P < .001). The overall knowledge rate of COVID-19 cognition among 2232 pregnant women who were to undergo interventional prenatal diagnosis was 76.40%. The fit indices of the model were: CMIN/DF = 3.071, GFI = 0.999, AGFI = 0.993, CFI = 0.999, RMSEA = 0.030, NFI = 0.998, and TLI = 0.992, indicating that the model had a good fit and the model was scientifically valid. Pregnant women in Sichuan province who are to undergo prenatal interventional diagnosis have a medium level of COVID-19 awareness, and their level of COVID-19 awareness and social support will directly affect their anxiety and depression level, and their anxiety level will also affect their depression level. We should give more attention to pregnant women, especially those in particular situations such as advanced age, poor maternal history, family history of genetic disease, etc, they should be given adequate care and social support, and multiple channels and types of health education should be provided for the COVID-19 to improve the pregnant women's knowledge of COVID-19, which is important for improving the mental health of pregnant women.
