A Multi-method Approach in Qualitative Research

A portion of the following is taken from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 288-289).

In contrast to mixed methods, a multi-method approach in qualitative research is one in Multiple methodswhich the researcher combines two or more qualitative methods to investigate a research question or phenomenon. Although the terms “multi-method” and “multiple methods” are sometimes used to refer to qualitative–quantitative (or mixed-method) research (e.g., Brewer & Hunter, 2006; Snape & Spencer, 2003), this terminology is reserved here for research strategies that incorporate more than one qualitative method and do not include any quantitative methods.

Qualitative multi-method research—due to the additional data collection and analysis considerations—has the potential disadvantage of consuming valuable resources such as time and available research funds. However, this is not always the case and, under the appropriate conditions, multiple qualitative methods can prove very useful toward gaining a more fully developed complexity and meaning in the researcher’s understanding of a subject matter compared to a single-method research design (cf. Denzin & Lincoln, 2011; Flick, 2007).

Ethnography is one such example. Observation is the principal method in an ethnographic study; however, it is often supplemented with other qualitative methods such as in-depth interviews (IDIs), focus group discussions, and/or documentary review in order to provide a more complete “picture” of the issue or phenomenon under investigation. Other applications of multi-method qualitative research are not uncommon. Lambert and Loiselle (2008), for instance, combined focus group discussions and IDIs in a study with cancer patients concerning their “information-seeking behavior.” These researchers found that this multi-method approach enriched the study because one method helped inform the other—for example, group discussions identified relevant questions/issues that were then used in the IDIs—and contributed unique information—for example, the IDIs were effective in obtaining details of patients’ information-seeking processes—as well as contextual clarification—for example, the focus groups were more valuable in highlighting contextual influences on these processes such as the physicians’ preferences or recommendations. Lambert and Loiselle concluded that the multi-method research design “enhanced understanding of the structure and essential characteristics of the phenomenon within the context of cancer” (p. 235).

Research Design Review has published articles on two special types of multiple-method qualitative research—case study and narrative research—each of which is a form of “case-centered” qualitative research, a term coined by Mishler (1996, 1999) and used by others (cf. Riessman, 2008) to denote a research approach that preserves the “unity and coherence” of the research subject throughout data collection and analysis. A six-step approach to case-centered research design is discussed in this article.

Regardless of the particular multi-method design or type of research, a multiple-method approach requires a unique set of qualitative researcher skills. These skills are discussed in this article—“Working with Multiple Methods in Qualitative Research: 7 Unique Researcher Skills.”
