Mixed method and multiple paradigm research


Myers & Avison argued in their book of qualitative research in IS that case study could be distinguished as positivist, interpretive or critical case study. Conducting mixed method research within one paradigm seems possible. However, is it considered acceptable in IS to use different kind of method in mixed method research, which have different underlying paradigm? For example Interpretive case study with positivist experiment.

Jansen & Brinkkemper (2009) described about the internal, external validity and empirical reliability for their case study. Would it be more appropriate to use the term of credibility, transferability and dependability? Or perhaps, it arises because of their stance on Yin’s positivistic principle?
