This article is the fourth and final in a series providing practical guidance for qualitative research. It addresses frequently asked questions about trustworthiness and publishing. The quality criteria for qualitative research are credibility, transferability, dependability, and confirmability. Reflexivity is also essential for ensuring transparency and quality. Writing a qualitative article reflects the iterative nature of the research process, with continuous data analysis and refinement. Editors assess whether the research is new, true, and relevant. An effective cover letter enhances confidence in these aspects and explains why a qualitative design was used. Qualitative research requires a thick description of participants and the research process to enable transferability judgments. Credibility is ensured through prolonged engagement, triangulation, and member check. Transferability involves assessing whether findings can be applied to other contexts. Dependability concerns consistency in the research process, while confirmability ensures neutrality in interpretation. An audit trail is needed to document the research process and ensure transparency. Reflexivity is crucial for self-awareness and reflection on the researcher's role and assumptions. Publishing qualitative research involves a structured approach, often longer than quantitative articles. The Results section in qualitative research includes synthesis and interpretation, while quantitative research has a strict division between Results and Discussion. Journal guidelines should be followed, and a cover letter should explain the study's qualitative design and quality criteria. Editors may prioritize quantitative research, so the cover letter must emphasize the study's relevance and quality. The article concludes with acknowledgments and disclosures.This article is the fourth and final in a series providing practical guidance for qualitative research.
