Table 2 The trend of the total PSRI scores in the different groups (A = 50, B = 53, C = 51) during pregnancy

Time	Before pregnancy	1st trimester	2nd trimester	3rd trimester	End of pregnancy	Total	P-value^a
Groups	Mean ± SD	Mean ± SD	Mean ± SD	Mean ± SD	Mean ± SD	Mean ± SD	P-value^a
Group A	71.47 ± 16.84	45.12 ± 16.26	53.76 ± 17.83	57.68 ± 18.79	57.04 ± 16.73	57.01 ± 19.17	P < 0.001
Group B	71.55 ± 14.03	50.54 ± 18.62	51.63 ± 13.89	45.77 ± 14.59	36.92 ± 14.16	51.29 ± 18.87	P < 0.001
Group C	73.48 ± 13.56	45.25 ± 19.00	49.18 ± 16.91	42.59 ± 17.57	35.37 ± 14.80	49.17 ± 20.88	P < 0.001
Total	72.17 ± 14.79	47.01 ± 18.08	51.53 ± 16.28	48.60 ± 18.13	42.98 ± 18.07	52.49 ± 18.01
Effect Size	0.13	0.30	0.28	0.83	1.20	0.43
P-Value^b	P = 0.75	P = 0.24	P = 0.36	P < 0.001¥	P < 0.001¥

^aThe repeated measures ANOVA
^bThe one-way ANOVA
¥: According to Tukey’s post-hoc test: There was a significant difference between the mean total scores of PSRI and Group A-C and Group A-B (P < 0.001) but there was no significant difference between the mean total scores of PSRI and Group B-C (P > 0.05)
