The study was completed with 109 parents (54 experimental group, 55 control group). Introductory Information Form, Prenatal Attachment Scale, Semantic Difference Scale (Me as Mother - My Baby), Maternal Attachment Scale, Pharis Self-Confidence Scale, Prenatal Father Attachment Scale and Father-Baby Attachment Scale were used to collect data. Institutional and ethical permissions were obtained to start the research. As a nursing approach, a 4-session motherhood identity development training was given to the experimental group based on the Maternal Role Attainment Theory.Number, percentage, mean, standard deviation, chi-square dependent and independent groups t test, Mann Whitney U test and Wilcoxon sign test were used in the analysis of the data.

After the pre-test was applied to the mother and father candidates included in the experimental group, "Maternity Identity Development Training" was given in the prenatal and postnatal period. This training program, based on Ramona T. Mercer's model of mothering role ability and covering four stages, was given to parents in their own homes by taking the necessary precautions, since it would be risky for the participants to be given in groups due to the COVID-19 Pandemic process. The training, which consisted of 2 sessions in the last trimester of pregnancy, 2 sessions at the end of the delivery before discharge and within the first week, and 4 sessions in total, lasted approximately 40 minutes. In addition, the parents in the training group were given a training booklet and the researcher's phone number for counseling and follow-up if needed.The training booklet, which contains the same information as the training content, was given to the parents in the experimental group at the end of the first training, and to the parents in the control group after the post-tests were administered.
