Aim: The aim of this study was to determine prenatal attachment and foetal health locus of control in pregnant women and factors affecting these parameters. Methods: This cross-sectional study was conducted with 156 pregnant women (77 low-risk and 79 high-risk pregnancies). The study was carried out between August 2015 and February 2016. The data collection instruments included a Participant Information Form, the Prenatal Attachment Inventory and the Foetal Health Locus of Control Scale. Results: Pregnant women's education and foetal health locus of control levels had positive and significant effects on prenatal attachment, and education had an effect on foetal health locus of control. Foetal health locus of control explained 6.3% of the total variance in prenatal attachment levels. Conclusion: As the educational statuses of pregnant women affected their prenatal attachment and foetal health locus of control, information, counselling and care should be prioritized for women with low education levels, in line with their needs. This is particularly important in terms of improving the control of pregnant women with lower prenatal attachment levels or internal locus of control over foetal health.
