Comparison of response options and actual symptom frequency in the Japanese version of the Edinburgh Postnatal Depression Scale in women in early pregnancy and non-pregnant women

Table 4 Comparison between the four groups of pregnant women based on the EPDS-S and FREQ-S

		N (n = 346)	EP (n = 4)	FP　(n = 12)	P (n = 20)
EPDS-S	Anhedonia	0.09 ± 0.26	0.87 ± 0.63	0.13 ± 0.31	0.63 ± 0.46	p<0.0001
	Anxiety	0.47 ± 0.58	1.00 ± 0.71	0.79 ± 0.58	1.90 ± 0.60	p<0.0001
	Depression	0.55 ± 0.50	1.63 ± 0.48	1.04 ± 0.54	1.63 ± 0.53	p<0.0001
FREQ-S	Anhedonia	0.31 ± 0.55	1.13 ± 0.85	0.67 ± 0.62	1.13 ± 0.60	p<0.0001
	Anxiety	0.31 ± 0.55	0.75 ± 0.65	1.96 ± 0.96	1.85 ± 0.76	p<0.0001
	Depression	0.42 ± 0.47	1.38 ± 0.48	1.79 ± 0.69	1.83 ± 0.49	p<0.0001

The p-values represent the results of one-way analysis of variance among the four groups. N negative for both scores, EP positive for EPDS-S only, FP positive for FREQ-S only, P positive for both scores (cutoff value = 13 points)
