The Introductory Characteristics Form, Prenatal Psychosocial Health Assessment Questionnaire and Prenatal Attachment Inventory were used to collect the data. Results: It was found in the study that 84.9% of the pregnancies were planned, 83.8% of them were at the last trimester, and 31.3% of them were their first pregnancy. The mean score of pregnant women was 4.54±0.18 (range: 3.87 to 4.87) in the Prenatal Psychosocial Health Assessment Questionnaire and 72.24±7.48 (range: 50.00 to 84.00) in the Prenatal Attachment Inventory. It was found that the mean scores obtained in the Prenatal Psychosocial Health Assessment Questionnaire were significantly different between the groups according to age, education level, family type and number of pregnancy. There was also significant difference in the mean scores obtained in the Prenatal Attachment Inventory between the groups according to age, education level, family type, number of child and household income level.
