Abstract The aim of this study was to examine the stress, anxiety, intolerance of uncertainty, and psychological well-being of pregnant women with and without threatened miscarriage. This is a case-control study. The research was carried out between January 2022 and March 2022 in the early pregnancy service and obstetrics clinic of the only training and research hospital in a province in the Central Anatolian Region of Turkey. Two hundred and one pregnant women with threatened miscarriage constituted the study group and 201 pregnant women without threatened miscarriage constituted the control group. A total of 402 pregnant women were included in the study. Stress, anxiety, and intolerance of uncertainty were found to be important risk factors affecting the psychological well-being of pregnant women with threatened miscarriage at a rate of 52% (F = 63,196, p < 0.001). In addition, the pregnant women with threatened miscarriage had higher levels of stress, anxiety, and intolerance of uncertainty, and their psychological well-being was considerably lower compared to pregnant women without threatened miscarriage (p < 0.05). There was a moderate and negative relationship between psychological well-being and intolerance of uncertainty (p < 0.05). It was determined that stress, anxiety, and uncertainty of pregnant women with threatened miscarriage were considerably higher compared to controls, and their psychological well-being was adversely affected. Health professionals should evaluate the levels of anxiety, stress, intolerance of uncertainty, and psychological well-being of pregnant women, especially in the routine follow-up of pregnant women with threatened miscarriage, and they should provide holistic care, not only physiologically but also bio-psychosocially. IMPACT STATEMENT What is already known on this subject? Although there are many studies on the emotional and psychological effects of miscarriage, there are limited studies on the effect of threatened miscarriage on the mental health of pregnant women. What do the results of this study add? Stress, anxiety, and intolerance to uncertainty were found to be important associated risk factors that negatively affect the psychological well-being of pregnant women with threatened miscarriage. It was determined that the pregnant women with threatened miscarriage had higher levels of stress, anxiety, intolerance to uncertainty, and their psychological well-being was much lower than the pregnant women without threatened miscarriage. It was determined that there was a moderate and negative relationship between the mean psychological well-being of pregnant women and the mean scores of intolerance to uncertainty. What are the implications of these findings for clinical practice and/or further research? This is the first case-control study to examine the determination of stress, anxiety, intolerance to uncertainty and psychological well-being of pregnant women with and without threatened miscarriage. Health professionals should evaluate the anxiety, stress, intolerance of uncertainty levels and psychological well-being of pregnant women, especially in the routine follow-up of risky pregnant women, and should provide holistic care not only physiologically but also bio-psychosocially to these pregnant women with a holistic approach.
