A total of 64 pregnant women were assigned into two groups of cases and controls. Both groups filled out the Perceived Stress Scale at pre-test. Cognitive-behavioral coping skill training was delivered to the case group. After the end of the intervention, both groups completed the same scale again. The results showed that the mean perceived stress of the cases and controls was 27.77 ± 6.033 and 18.97 ± 3.268, respectively (p = 0.001). Therefore, midwives are recommended to plan educational interventions to decrease perceived stress in pregnant women.
