This chapter deals with the research design, research setting, research participants, and research instruments which all contribute to the credibility of the study. Research Design The qualitative method was applied to the research investigation. Data are utilized in qualitative research to decide which explanation should be developed further. It entails gathering and examining non-numerical facts in order to comprehend ideas, viewpoints, or experiences. Thus, qualitative research provides a realistic example of postdiction research and is an effective way to avoid dissemination bias. Because the goal of this study is to describe and investigate the lived experiences of those mothers with postpartum depression, the researcher based her methodology on a qualitative approach. The qualitative research approach frequently involves reflection and flexibility. It can also be utilized by researchers to develop fresh research concepts or acquire in-depth insights into a topic. This qualitative research employs phenomenological research to elaborate on the various emotions experienced by mothers with postpartum depression. The goal of a phenomenological investigation is to explain a phenomenon, and not describe the phenomenon. It investigates any emerging phenomena, including human emotions, thoughts, and behaviors. It requires adopting a specific attitude and establishing conscious awareness of the bodily and emotional events they underwent. Phenomenological investigations aim to describe anything that supports the researchers' ideas in terms of the hypothesis that underlies their moral views.
