Findings of perceived infertility stress
infertility
The results of this study showed that the mean and standard deviation of perceived infertility stress score before the intervention was 146.16 ± 16.92 in the control group and 156.53 ± 9.31 in the intervention group (P = 0.05). The mean perceived stress after the intervention on the day of ovum retrieval was 165.36 ± 8.98 in the control group and 155.83 ± 10.70 in the intervention group (P = 0.000). Mean perceived stress after the intervention on the day of embryo transfer in the control group was 165.35 ± 14.45, while it was 123.58 ± 22.92 in the intervention group (P = 0.00), (P = 0.00), and on the day of pregnancy test this score was 185.76 ± 26.56 in the control group and 127.61 ± 21.57 in the intervention group (P = 0.00). The mean perceived infertility stress was significantly different between the two groups after the intervention (Table Based on the results of Friedman test, stress score in the intervention group at the three stages after the intervention showed a significant reduction (P = 0.000). In the control group, the stress score of the samples showed a significant rising trend based on the results of Friedman test (P < 0.000) (Table Based on GEE test results, considering that the difference in baseline stress score between the two groups was statistically significant, after adjusting the effect of the baseline stress score, the stress score changes over time between the two groups were significant (P < 0.001). The effect size of stress on the days of ovum retrieval, embryo transfer, and pregnancy test was 0.41, 1.69, and 2.46, respectively, which was significant on the day of embryo transfer and day of pregnancy test (Table Figure Comparison of mean and standard deviation of Newton's infertility stress score in infertile women, separated into two intervention and control groups, in three situations before and after the intervention on the days of egg collection, embryo transfer and pregnancy test.
