To investigate the correlation between the adverse mood survey of pregnant women with threatened abortion after in vitro fertilization-embryo transfer (IVF-ET) and their psychological resilience and coping style. Methods: A total of 118 pregnant women with threatened abortion after IVF-ET were selected as the survey objects from January 2021 to January 2022. After admission of hospital, the general situation questionnaire, self-rating anxiety scale (SAS), self-rating depression scale (SDS), connor-davidson resilience scales (CDRISC), and medical coping modes questionnaire (MCMQ) were used to survey. The correlation between the adverse emotions of the women and their psychological resilience and coping style was explored by Pearson correlation analysis. The related factors affecting the adverse emotions of the women with threatened abortion after IVF-ET were explored by multiple linear stepwise regression analysis. Results: The scores of anxiety and depression of 118 pregnant women were 60.7±6.7 points and 63.6±7.4 points, and the total scores of mental resilience and coping style of these women were 54.1±8.7 points and 49.2±9.0 points. Correlation analysis showed that the scores of the adverse emotions (anxiety and depression), of the women with threatened abortion after IVF-ET were negatively correlated with their scores of various dimensions of mental resilience and their facing scores, and which were positively correlated with their avoidance and yielding scores (all P＜0.05). Univariate analysis showed that the scores of the adverse emotions (anxiety and depression) of the women with threatened abortion after IVF-ET were related to their age, abortion frequency, education level, medical payment method, and family income (P＜0.05). The results of multiple linear regression analysis showed that tenacity, optimism, strength, facing, avoidance, yielding, and abortion times of the women had all entered into the regression equation of anxiety (F=66.125, P＜0.001, R2=0.615), and tenacity, optimism, strength, facing, avoidance, yielding, and abortion times of the women had all entered into the regression equation of depression (F=56.441，P＜0.001，R2=0.478). Conclusion: The adverse emotions (anxiety and depression) of the women with threatened abortion after IVF-ET are common, and which are closely related to their psychological resilience and coping style. In clinic, the corresponding intervention measures for the women should be implemented to improve their psychological resilience level and the positive coping style should be encouraged, so as to achieve the effect of alleviating anxiety and depression.
