Ensuring Credibility and Trustworthiness in Qualitative Inquiries

Abstract

This chapter examines conceptualizations and applications of validity in qualitative research within applied linguistics and language education. It outlines the importance of addressing validity given the complexity of language phenomena and contextual embeddedness of language research. Strategies to enhance ethical qualitative practice are discussed. Limitations of existing validity approaches for these fields are critiqued and alternative perspectives proposed. Additionally, the chapter analyzes myriad validity considerations regarding the multifaceted nature of language and aims of language-focused inquiries, providing case study examples. Methodological and ethical strategies to strengthen qualitative research validity are explored, emphasizing reflexivity and researcher positionality. The chapter argues for embracing expanded conceptual lenses aligned with ethical priorities to realize rigorous, equitable and justice-oriented qualitative practice.
