The study will be conducted with participants who will give birth at Farabi Training and Research Hospital in Darıca District, Kocaeli Province.

The sample size of the study was calculated using the G*Power 3.1.9.2 program, and the effect size of the Edinburgh Postnatal Depression Scale (EPDS) score in the Sun et al. (2021) study was considered in the effect size calculation. In the relevant article, the effect size is reported as effect size: 0.47. In our planned research, the minimum number of individuals to be sampled was calculated using G*Power 3.1.9.2 with effect size: 0.47 α= 0.05, power: 0.80, and the sample size was set at a minimum of 57 participants in each group. In anticipation of possible data loss, the study will be completed with a total of 140 participants, including 70 cases and 70 routine discharge training groups. This research aims to determine the effect of discharge training on maternal blues and postpartum depression on the levels of maternal blues and postpartum depression during postpartum follow-up.

The purpose of this study is to determine the effect of discharge training on maternal sadness and postpartum depression on the level of maternal sadness and postpartum depression in the puerperium follow-up. In this context, the hypotheses of the study are as follows;

Hypothesis 1:

H0: There is no difference in the total scores of the Maternal Sadness Scale used in the postpartum follow-up of mothers who received discharge training on maternal sadness and postpartum depression and mothers who did not receive training.

H1: There will be a difference in the total scores of the Maternal Sadness Scale used in the postpartum follow-up of mothers who received discharge education on maternal sadness and postpartum depression and mothers who did not receive education.

Hypothesis 2:

H0: There will be no difference in total scores on the Edinburgh Postpartum Depression Scale used in the postpartum follow-up of mothers who received discharge education on maternal grief and postpartum depression and mothers who did not receive education.

H1: There is a difference in the total scores of the Edinburgh Postpartum Depression Scale used in the postpartum follow-up of mothers who received discharge education on maternal grief and postpartum depression and mothers who did not receive education.

Mothers enrolled in the study will be randomly assigned to groups, and homogeneity in the distribution of groups will be ensured. "Random Allocation Software Program will be used to randomly assign mothers to groups, and a randomization list for the study will be generated by determining the number and group number of each participant.

Postpartum women to be included in the study will be assigned to one of the routine discharge training and discharge education groups by the researcher according to the order in the randomization list. Only that mother will be studied until the mother assigned to the randomization group has been informed about the research and has completed the necessary training compared to the routine discharge training/discharge education group. After the mother's research process is completed, another mother who has been admitted to the ward and meets the research criteria will be assigned to the other group on the randomization list and the necessary practices will be carried out. If the mother leaves the study for any reason during the study, the first mother admitted to the ward who meets the research criteria will be assigned to the other group on the randomization list.

In a randomized controlled trial with discharge education and routine discharge training groups, after the research groups are formed; In the first phase, the participants assigned to the discharge education group will be given a discharge education on postpartum depression and motherhood blues through a face-to-face interview technique and a "personal information form" will be used. It is expected that the discharge training and data collection will take approximately 15-20 minutes. After the training, an information booklet prepared by the researchers after a literature review will be given to the participants in print, via email or WhatsApp, depending on the researcher's preference. 5-7 days of postpartum period after the mothers are discharged. On these days, the researcher will call you and inform you that the 32-item Motherhood Sadness Scale will be administered. Data collection is expected to take approximately 5-10 minutes. Interviewed mothers will be contacted by the researcher by telephone at 6 weeks postpartum after discharge from the hospital and informed that the 10-item Edinburgh Postpartum Depression Scale will be administered. Data collection is expected to take approximately 5 minutes.

After the scale data are collected during the interview, the researcher will provide brief verbal information about the Motherhood Blues Scale and the Edinburgh Postpartum Depression Scale scores, and mothers whose scale scores are determined to be high will be referred to the necessary units to increase necessary psychiatric counseling and social support.

The mother assigned to the routine discharge training group will receive routine hospital discharge education. Then the "Personal Information Form" will be used. The mother whose contact information was collected will be examined by the researcher on the 5th-7th day of her postpartum period after her discharge. On these days, the researcher will call you and inform you that the 32-item "Motherhood Sadness Scale" will be administered. Data collection is expected to take approximately 5-10 minutes. Interviewed mothers will be contacted by the researcher by telephone at 6 weeks postpartum after discharge from the hospital and informed that the 10-item Edinburgh Postpartum Depression Scale will be administered. Data collection is expected to take approximately 5 minutes. After the scale data have been collected during the interview, the researcher will provide brief verbal information about the Motherhood Blues Scale and Edinburgh Postpartum Depression Scale scores, and mothers whose scale scores are determined to be high will be referred to the necessary services to enhance necessary psychiatric care and social support.
