This study aimed to analyze the current status of women's perception of social support levels, psychological resilience, anxiety, and depression levels during IVF-ET, as well as investigate the influence of perceived social support and psychological resilience on the anxiety and depression levels of women undergoing IVF-ET and the mediating role of psychological resilience in this process. In this study, a convenience sampling method was used to administer a questionnaire survey among 433 women undergoing IVF-ET. Then, multivariate linear regression models were applied to identify factors influencing anxiety and depression. Lastly, mediation effect analysis was conducted to explore the mediating role of psychological resilience. The incidence of anxiety and depression was 42% and 46.4%, respectively. The mean score of the Perceived Social Support Scale (PSSS) indicated a high to moderate level of support, while the mean score of the Conner-Davidson Resilience Scale (CD-RISC) suggested moderate psychological resilience. Perceived social support was positively correlated with psychological resilience, and both were negatively correlated with anxiety and depression. Perceived social support and psychological resilience were identified as influencing factors of anxiety and depression (P < 0.001). Moreover, there was a partial mediating effect of psychological resilience between perceived social support and both anxiety and depression (P < 0.01). These results highlight the need for healthcare providers to assess patients' levels of psychological resilience and perceived social support when developing mental health interventions in order to mitigate the risk of anxiety and depression and concomitantly enhance fertility outcomes.
