3. validity in qualitative research revisited, Cho &Trent

• transactional validity
  • interaction between the inquiry and participants
    • member checking. Guba&Lincoln,1995 1985 2000 : the most crucial technique for establishing credibility
      • reassuring the credibility of constructions of the participants
        • Weak form
        • Strong form
    • bracketing, Moustakas,1994
    • triangulation, Denzin,Hammersley,Atkinson,Seale
      • Verifying facts through multiple data sources
  • Validity of the text/account is of primary importance
  • Researchers’ construction of realities will inevitably be reconstructions, interpretations.
• transformational validity
  • Lather 1986, Walcott 1990
  • Lather1987, propose a transgressive approach to validity that emphasizes a higher degree of self-reflexivity
• The authors: a recursive,process-oriented view of validity
  • reconstruct a mutually incompatible methodological “ contrast between diversity and control” in education ( Hammersley, 2002)
  • we must rely not just on our “assumption about our plausibility and credibility, but also on what we take as likely to be the judgements of other members of the research community” (Hammersley, 1998)
• Examples
  • Richardson,1997 “crystallization”
  • Lather, “catalytic validity”
  • Foucault,Kvale,1995 “pragmatic validity”
  • Beverley, 2000 “testimonio”
• Lincoln&Guba1985: trustworthiness in naturalistic inquiry
  • Trustworthiness
    • Credibility
    • Transferability
    • Dependability
    • Confirmability
• Transformational validity
  • Definition
    • A progressive, emancipatory process leading toward social change that is to be achieved by the research endeavor itself.
• Transactional validity
  • Definition
    • An interactive process between the researcher, the researched, and the collected data
  • Aim
    • Achieving a relatively higher level of accuracy and consensus
  • Means
    • Revisiting facts, feelings, experiences, and values or beliefs collected and interpreted
  • Seale, 1999: labels this approach “interpretivist criteriology”
  • Maxwell,1992: describes this approach “descriptive” and “interpretive”
• Purpose of the article
  • Examine the two approaches
  • Probe Donmoyer’s 2001 proposal: making sense of the contemporary field of qualitative research as a whole, and extend it to the issue of validity
  • Holistic view of validity in qualitative research
• Sealed, 1999
  • Relationship between claims and evidence
    • Seeks a middle ground for validity conceptualization between the extremes of scientific and poststructuralist/emancipatory approaches
    • He regards “ claims as always subject to possible revision by new evidence.”
• Creswell&Miller, 2000
  • The conception of validity that is appropriate is dependent upon the inquiry paradigms being engaged.
  • problematic: based primarily upon a narrowly defined nature of choice connected to overlapping modes of inquiry.
