Can methods / methodologies rooted in social constructivist paradigms (e.g reflexive TA (Braun and Clark) or grounded theory (Charmaz) ) be meaningfully integrated in mixed methods studies? Or is one restricted to only using post-positivist yet qualitative/semiqualitative methods like the interrater -reliability coding method of TA (Boyatzis, 1998) if the goal is to incorporate it into a sequential mixed methods study?
The reason I ask is that most social constructivist paradigms do not lend themselves well to the idea of "variables" which are at the heart of any quantitative study.
My design is a exploratory sequential mixed methods study where a smaller qualitative study will inform a larger quantitative one. I am asking if a theory of trauma (developed in a different cultural context , but well researched- already has established questionnaires etc.) is applicable as a backbone to map familial violence on in a culturally different and diverse South Asian scenario. The idea is to understand the manifestation of violence and trauma , identify cross cultural mediators etc. through the qualitative data, before moving on to using the established quantitative questionnaires (which may require adaptation based on the qualitative data).
Any discussion, resources on this issue, examples of papers where different paradigms have been meaningfully integrated into a mixed methods design, will be very helpful.
Thank you.
