Objective: It was aimed to examine the factors affecting marital satisfaction and prenatal attachment in pregnant women and the effect of marital satisfaction on prenatal attachment. Methods: The study was conducted in descriptive type. The data of the study were collected from 252 pregnant women from 01 April to 30 June 2021. Data were collected using by personal information form, Prenatal Attachment Inventory (PSI), and Marriage Satisfaction Scale (EDS) forms. Spearman correlation analysis was used to analyze the relationship between a number and percentage distributions, mean, non- parametric tests (Kruskal Wallis, Mann-Whitney-U), and continuous variables in the evaluation of the data. Results: The economic status of the pregnant women (p=0.027), age at marriage (p=0.030), meeting the spouse (p=0.006), planning status of pregnancy (p=0.017), gravidity (p=0.003) and trimester of pregnancy (p=0.003) affects their prenatal attachment (p<0.05). EDS compared to those residing in the province who live in the village (p=0.019), those who met their spouses by dating/friendship (p=0.002), and those who described their relationship with their spouse as good/fair/very bad (p=0.004) total scores were found to be higher (p<0.05). It was found that there was a negative significant (p<0.05) relationship between PSI and EDS total scores of pregnant women. Conclusion: Prenatal attachment levels of the pregnant women included in the study were moderate. In pregnancy, age and number of pregnancies were found to affect prenatal attachment. Marriage satisfaction is negatively affected by the duration of marriage, the number of pregnancies and the gestational week. It was concluded that as the prenatal attachment levels of pregnant women increased, marital satisfaction decreased.
