In our research on authentic leadership and conflict management we're using a number of constructs such as authentic leadership ALQ, Thomas Kilman conflict mode instrument CPP , and conflict management style based on the the Rahim organizational conflict inventory. We are trying to figure out if these three constructs are formative and therefore do not need reporting of reliability such as composite reliability. The data analysis technique we are using is smart PLS. I can make arguments both ways as to whether they are reflective or formative constructs. Is a construct designated reflective or formative or does it depend on how we use it in the research. Does anyone have any guidance on this?
