Shared Constructs in Research Design: Part 3 — Validity

validity in research designNot unlike Part 1 (concerning sampling) and Part 2 (concerning bias) of the discussion that began earlier, the shared construct of validity in research design has also been an area of focus in several articles posted in Research Design Review. Most notable is “Quality Frameworks in Qualitative Research” posted in February 2021 in which validity is discussed within the context of the parameters or strategies various researchers use to define and think about the dimensions of rigor in qualitative research design. This article uses the Total Quality Framework (Roller & Lavrakas, 2015) and criteria of Lincoln and Guba (1985) to underscore the idea that quality approaches to design cuts across paradigm orientation, leading to robust and valid interpretations of the data.

Many other qualitative researchers, across disciplines, believe in the critical role that the shared construct of validity plays in research design. Joseph Maxwell, for example, discusses validity in association with his realism approach to casual explanation in qualitative research (Maxwell, 2004) and discusses in detail five unique dimensions of validity, including descriptive, interpretative, and theoretical validity (Maxwell, 1992). And of course, Miles & Huberman were promoting greater rigor by way of validity more than three decades ago (Miles & Huberman, 1984).

More recently, Koro-Ljungberg (2010) takes an in-depth look at validity in qualitative research and, with extensive literature as the backdrop, makes the case that “validity is in doing, as well as its (un)making, and it exhibits itself in the present paradox of knowing and unknowing, indecision, and border crossing” (p. 609). Matteson & Lincoln (2008) remind educational researchers that validity does not solely concern the analysis phase of research design but “the data collection method must also address validity” (p. 672). Creswell & Miller (2000) discuss different approaches to determine validity across three paradigm orientations — postpositivist, constructivist, and critical — and “lens” of the researcher, participants, and researchers external to the study.

Among qualitative health researchers, Morse (2020) emphasizes the potential weakness in validity when confusing the analysis of interpretative inquiry with that associated with “hard, descriptive data” (p. 4), and Morse et al. (2002) present five verification strategies and argue that validity (as well as reliability) is an “overarching” construct that “can be appropriately used in all scientific paradigms” (p. 19).

These researchers, and those discussed in Part 1 – Sampling and Part 2 – Bias, are admittedly a small share of those who have devoted a great deal of thought and writing concerning these shared constructs. The reader is encouraged to utilize these references to build on their understanding of these constructs in qualitative research and to grow their own library of knowledge.
