"Data is collected through interviews, observations, or other qualitative methods. In this study, in-depth interviews with participants who are child maltreatment survivors were conducted to gather rich, detailed descriptions of their experiences. The analysis involves coding the data in stages: open coding, axial coding, and selective coding. This process helps identify key themes and categories that emerge from the data. Constant comparison is used, where data is continuously compared with emerging categories and concepts to refine and integrate them into a coherent theory. Participants are selected based on their ability to contribute to the emerging theory. This means that as the theory develops, researchers may seek out additional participants who can provide further insights or fill gaps in the data. The ultimate goal is to develop a substantive theory that explains the process of becoming a parent for child maltreatment survivors. This theory is grounded in the data collected and reflects the participants' perspectives and experiences."
