Correlation among irrational parenthood cognitions, fertility stress, and social support in patients with repeated implantation failure and the mediating effect of fertility stress: a cross-sectional survey

Abstract Purpose This study investigated the relationships among irrational conceptions of parenthood, fertility stress, and social support, as well as the mediating effect of fertility stress, in patients with repeated implantation failure. Methods Patients who underwent assisted reproductive technology due to repeated implantation failure at the Reproductive Centre at Women's Hospital between January 2020 and August 2022 were selected using cross-sectional research and convenience sampling. A total of 129 patients with recurrent implantation failure were investigated using the Irrational Parenthood Cognitions Questionnaire (IPCQ), Fertility Problem Inventory (FPI), and Social Support Rating Scale (SSRS). Results The differences in irrational parenthood cognitions, fertility, stress, and social support among patients with repeated implantation failure in the education and yearly household income subgroups were statistically significant (P<0.001). Pearson correlation analysis revealed that irrational parenthood cognitions were favorably correlated with all measures of reproductive stress (r=0.384 to 0.664, all P<0.01) and negatively correlated with social support (r=-0.310, p<0.01). The fertility stress of patients with repeated implantation failure fit the structural equation model of irrational parenthood cognitions and social support well [X2/df=2.04, Comparative Fit Index (CFI)=0.944, Tucker–Lewis (TLI)=0.905, Root Mean Squared Error of Approximation (RMSEA)=0.090]. The bootstrap test results revealed that the mediating effect of the 95% CI ranged between -0.506 and -0.109, and the interval did not contain 0. Fertility stress had a strong mediating effect on the relationship between irrational parenthood cognitions and social support. Conclusions The mediating effect of reproductive stress on the relationship between irrational parenthood cognitions and social support in patients with repeated implantation failure was significant. It is important for medical and nursing staff to address physical and psychological illnesses and develop effective intervention strategies from the perspectives of fertility stress, social support, and cultural background, with the ultimate goal of improving mental health.
