Journal of Mixed Methods Research, Ahead of Print.
The purpose of this article is to illustrate how mixed methods research can be applied as a rigorous method for developing a quantitative instrument responsive to an indigenous culture in Malaysia. In a sequential research design, a three-round Delphi study was conducted to integrate open-ended and free-listing data, and to generate a list of items. The items were subjected to a field test to ensure reliability. A correspondence analysis of scale was employed to examine the validity of the instrument. This research contributes to mixed methods by illustrating the value of Delphi groups as part of a mixed methods research design and the utility of mixed methods research in advancing the validity and reliability of an indigenous cultural values instrument.
