Possibility of generalization
Perinatal mental health problems are caused by pregnancy and lactation, which makes it difficult to use drugs, including sleeping pills. In addition, access to psychosomatic medicine and counseling is difficult during childcare, making it easy for women to become isolated. This study suggests that intervention by midwives may also be effective. CBT is a psychological therapy for which there is ample evidence of effectiveness, and by verifying the effectiveness of CBT programs by midwives in randomized controlled trials, it will be possible for midwives (who are most familiar with pregnant and nursing mothers) to intervene.
