The research was planned to develop the "My Breastfeeding Guide" mobile nursing application, which was developed based on Dennis' Breastfeeding Self-Efficacy Theory and Pender's Health Promotion Model, and to determine its effect on the postpartum breastfeeding process, breastfeeding self-efficacy, infant feeding and attachment. The research is in randomized controlled experimental and longitudinal (prospective) design. The research will be carried out with pregnant women who applied to Famagusta State Hospital Obstetrics and Gynecology Polyclinic and a pregnant polyclinic of a private hospital in Famagusta. Pregnant women who applied to Famagusta State Hospital Gynecology and Obstetrics Polyclinic and private hospital's pregnancy polyclinic and met the inclusion criteria of the study will constitute the population of the research. The research will be designed in two groups as the mobile nursing practice group (intervention) and standard care group (control) developed based on Dennis's Breastfeeding Self-Efficacy Theory and Pender's Health Promotion Model. By calculating the sample size in the research, 44 people in the intervention group and 44 people in the control group will reach a total of 88 people. Pregnant Identification Form, Maternal Information Form, Breastfeeding Self-Efficacy Short Form Scale (Postnatal Form), Antenatal Self-Efficacy Short Form Scale, Infant Nutrition Attitude Scale, Breastfeeding Rating Scale, Maternal Attachment Scale and Breastfeeding Self-assessment Form will be used to collect data. Statistical analyzes of the data obtained from the research will be made using the Statistical Package for the Social Science (SPSS) 20.0 package program. While evaluating the research data, frequency, percentage, mean, standard deviation, median, variance analysis from descriptive statistical methods will be used. For homogeneity test between intervention and control groups, the Chi-square test for categorical variables, Mann Whitney test for numerical variables, and sociodemographic variables (age, education status, employment status of himself and his spouse, income level, etc.) and whether the groups are similar in terms of some characteristics. U test will be used. The conformity of the scale scores to the normal distribution will be evaluated with the Shapiro-Wilk test. The results will be evaluated at the 95% confidence level, and the significance at the p<0.05 level.

Aim:

The research was planned to develop the "My Breastfeeding Guide" mobile nursing application, which was developed based on Dennis' Breastfeeding Self-Efficacy Theory and Pender's Health Promotion Model, and to determine its effect on the postpartum breastfeeding process, breastfeeding self-efficacy, infant feeding and attachment.

Hypotheses:

1. H1: Postpartum breastfeeding self-efficacy score averages of the intervention group using the mobile nursing application developed based on the model are higher than the control group.
2. H1: Postpartum infant feeding attitude mean score of the intervention group using the mobile nursing application developed based on the model is higher than the control group.
3. H1: Postpartum breastfeeding mean score of the intervention group using the mobile nursing application developed based on the model is higher than the control group.
4. H1: Postpartum maternal-newborn attachment point averages of the intervention group using the mobile nursing application developed based on the model are higher than the control group.

Type of Research:

It is a randomized controlled experimental and longitudinal (prospective) study.

Place and Time of Research:

The research will be carried out with pregnant women who applied to Famagusta State Hospital Obstetrics and Gynecology Polyclinic and a pregnant polyclinic of a private hospital in Famagusta. The care services of both hospitals are limited to the hospital. Following the approval of the research ethics committee, data collection, data analysis and preparation of the research report are planned as twenty-four months (September 2022-September 2024).

Pilot (preliminary) research:

Pilot (preliminary) research is the preliminary version of the main research and is carried out to determine the feasibility of the main research and the difficulties in conducting the research. Four people will be recruited for each group to represent 10% of the people included in the sample for the pilot (preliminary) study. The purpose of the study was explained to each pregnant woman who was included in the pilot application and their written consent was obtained. The obtained data were analyzed using statistics and it was determined that the research was applicable. Therefore, it was decided to continue the research without making any changes. Mothers in the pilot study were also included in the main study.

Collection of Research Data:

Breastfeeding counseling to be implemented will be carried out in line with the TR Ministry of Health Postpartum Care Management Guide, WHO, UNICEF recommendations for successful breastfeeding, since there is no protocol for prenatal and postnatal care in the TRNC, and the collection of research data starts in the prenatal period and continues in the postpartum period. will continue.

The data will be collected by the researcher from pregnant women who applied to the Famagusta State Hospital Obstetrics and Gynecology Polyclinic and a pregnant outpatient clinic of a private hospital in Famagusta, who met the inclusion criteria and accepted to participate in the study. After the follow-ups in the polyclinic, the pregnant women will be directed to the Breastfeeding Polyclinic where the researcher is located. Pregnant women will be informed about the purpose and process of the research, and pregnant women who volunteered to participate in the research will be evaluated according to the criteria for inclusion in the research. Randomization will be made for those who meet the criteria for inclusion in the study, and after the intervention and control groups are determined, informed consent form and written consent will be obtained. After the implementation of the data collection tools, the intervention and control groups will be trained using the Breastfeeding Education Booklet and a Breastfeeding Education Brochure will be given as a summary of the training. Afterwards, pregnant women in the intervention group will be asked to download and follow the mobile nursing application on their phones throughout the duration of the research.

After the first encounter with the pregnant woman, other data will be collected at 24 for postpartum vaginal deliveries, at 48 hours for cesarean deliveries, at one week, at six weeks, and at six months. At the specified follow-up times, while the intervention group fills in the data collection tools via the mobile nursing application, the mothers in the control group will be contacted via Whatsapp and asked to fill them out via Google Forms®. To avoid data loss, each question will have to be answered and each form will be allowed to be filled once to avoid duplication.

Pregnancy identification form at the first encounter with the pregnant woman, AEÖS to identify mothers with a high risk of stopping breastfeeding prematurely and giving additional food, BBQ to measure breastfeeding attitudes regarding issues such as initiation and maintenance of breastfeeding, approach to formula use, 24 for postpartum vaginal deliveries, cesarean section deliveries In the first 48 hours, the mother's identification form for the mother in the first 48 hours, the EAS to determine how competent the mothers feel about breastfeeding, the IBFAT to evaluate the limitations of breastfeeding in the early postpartum period, and the Breastfeeding Self-Assessment Form for the mother in the intervention group to evaluate her own breastfeeding, the mother at the first week postpartum. Introductory form, EÖÖ, IBFAT and Breastfeeding Self-Assessment Form for the same reasons, mother identification form at the sixth week postpartum, EÖÖ, IBFAT, Breastfeeding Self-Assessment Form for the same reasons, and MDS due to the attachment phase for six to eight weeks after birth. In order to find out whether breastfeeding is continued in the last month, the mother's introduction form, the EÖÖ and the Breastfeeding Self-Assessment Form will be applied for the mother to evaluate her own breastfeeding.

Breastfeeding Education Booklet:

Education with the breastfeeding education booklet will be applied to both the intervention and control groups at the time of the first encounter with the pregnant women, after the application of the data collection tools. The booklet will be developed based on Dennis' Breastfeeding Self-Efficacy Theory and Pender's Health Promotion Model. Since there is no antenatal and postnatal care guide published by the TRNC Ministry of Health, the Turkish Ministry of Health Antenatal Care Management Guide and Postpartum Care Management Guide are eight sub-titles of WHO and UNICEF's ten step recommendations for successful breastfeeding. It has been prepared in line with basic clinical practice recommendations. The recommendations are as follows (WHO, 2018);

1. Pregnant women and their families are informed about the importance and management of breastfeeding.
2. Mothers are provided with skin-to-skin contact with their babies as soon as they are born, and mothers are supported to start breastfeeding as soon as possible and to maintain uninterrupted contact.
3. Support is offered to mothers in initiating and maintaining breastfeeding and managing common difficulties.
4. Unless there is a medical necessity, any food or liquid other than breast milk is not given to the newborn.
5. It is ensured that mothers are kept together with their babies and stay in the same room 24 hours a day.
6. Mothers are supported in recognizing and responding to the signs their babies give when their babies are hungry.
7. Counseling services are provided to mothers on bottle and pacifier use and its risks.
8. Before discharge, parents and their babies are informed about the centers where they will be able to access continuous support and care services for breastfeeding.

In this direction, the aim of the breastfeeding education booklet is to develop and maintain the right breastfeeding behavior in the long term, and therefore to improve breastfeeding rates in the first six months and after, by providing information on the importance and application of breast milk and breastfeeding. After the content of the booklet was created, expert opinion was taken to evaluate it in terms of literacy, intelligibility, relevance and cultural suitability. For this purpose, the content was delivered electronically to 10 faculty members in the field of Women's Health and Diseases Nursing. The final version of the content of the booklet was created in line with the changes suggested for the content in line with the expert opinions.
