Midwifery care is a specific model of care in healthcare. A midwife is the only qualified caregiver for a pregnant woman, a woman in labor, a postpartum woman, and a newborn. The relationship between the midwife and the woman in labor, as well as the approach to care, can influence the woman's satisfaction with the childbirth experience, the midwife, and midwifery care, potentially impacting her mental health. Both mental and physical health are equally important components of overall health for every individual. Hormonal changes during pregnancy and the stressful event of childbirth can significantly affect a woman's mental health. The main goal of this research is to understand how the quality of midwifery care affects the mental health of women after the birth of their first child. The research was conducted online via the social media platform Facebook, in a group focused on childbirth and the exchange of childbirth experiences. The group has 23,958 members, and 338 women aged between 19 and 53 participated in the research. The questionnaire is anonymous and consists of four parts. The first part of the questionnaire includes a filter question to distinguish between first-time mothers and those who have had multiple children. The second part contains socio-demographic questions. The third part uses a questionnaire for assessing satisfaction with midwifery care, which was adapted for this research, and the fourth part uses the standardized Depression Anxiety Stress Scales - 21 Items (DASS-21). Out of 338 respondents, 203 stated that they were satisfied with midwifery care, 81 were ambivalent, and 63 were not satisfied with midwifery care. Levels of stress, anxiety, and depression were found to be higher than in the general population. Further research revealed that respondents who were more satisfied with midwifery care had lower levels of stress, anxiety, and depression compared to those who were not satisfied with midwifery care.
