Qualitative research has often been viewed as less rigorous than quantitative research, but it is a valid and distinct approach for studying human experiences. This article outlines criteria for evaluating qualitative research quality, strategies to enhance credibility, and examples from recent studies. Lincoln and Guba (1985) proposed four criteria: credibility, dependability, confirmability, and transferability, with authenticity added in 1994. Credibility refers to the truth of data and participant perspectives, achieved through researcher engagement, audit trails, and member checking. Dependability is about data consistency over time, confirmed by replication. Confirmability ensures data reflects participants' responses, demonstrated through detailed descriptions and participant quotes. Transferability allows findings to be applied to other contexts. Authenticity involves accurately representing participants' emotions and experiences. Whittemore et al. (2001) added primary and secondary validity criteria. Primary include credibility, authenticity, criticality, and integrity. Secondary criteria include explicitness, vividness, creativity, thoroughness, and congruence. Strategies to enhance credibility include triangulation, prolonged engagement, persistent observation, reflexivity, and audit trails. Member checking validates conclusions by involving participants. Reporting strategies provide evidence for credibility through detailed descriptions and participant quotes. Pedersen et al. (2013) exemplified these strategies, using thick quotes, audit trails, and multiple data sources to ensure credibility. Qualitative research is essential in nursing for understanding patient experiences, especially in cancer care. It enhances nursing knowledge by exploring emotions, experiences, and phenomena. Researchers must apply strategies to ensure credibility and trustworthiness, supporting the validity of qualitative findings.Qualitative research has often been viewed as less rigorous than quantitative research, but it is a valid and distinct approach for studying human experiences.
