anxiety
The level of anxiety is likely to vary depending on the stage of pregnancy and postpartum period. Therefore, we conducted a two-way analysis of variance (ANOVA) between the timing and the presence of the intervention. We found no interaction between timing and the presence of the intervention. The main effect was confirmed only for the time period, and the results of multiple comparisons (Bonferroni) showed that pre- (T1) > post- (T2) at α = 0.05. The results of the analysis for the intervention and control groups showed that the intervention group differed significantly in the degree of anxiety depending on the time of year (F(2, 58) = 7.838, p = .001), whereas the target group did not differ significantly in the degree of anxiety depending on the time of year (F(1.663, 46.553) = 2.214, p = .129).
