Integrated research design for sequential mixed methods

Mixed methods research offered a framework for designing, collecting, analysing and interpreting data using both qualitative (QUAL) and quantitative (QUAN) methods within one or more of the research stages (Leech & Onwuegbuzie, 2009). The sequencing of the use of mixed methods, the timing, weighting and the emphasis of one instrument above another is an important factor in designing mixed methods research (Creswell, 2009; Leech & Onwuegbuzie, 2009). It was decided to approach the research as two distinct, but interrelated studies in a sequential, equally weighted QUAN/QUAL approach where the quantitative study (Study 1), using a web survey, set the stage for the qualitative study which used semi-structured interviews (Study 2).

This integrated sequential research design enabled triangulation as it provided the researcher with an understanding of the studied social phenomenon from different vantage points (Brannen, 2005). For this purpose, the research processes started with an integrated research design matrix (see Annexure $) which was developed to map the research objectives, the underlying theory or constructs, the possible questions for the two instruments, possible analysis dimensions and references to ensure that all nuances of the phenomena to be explored, were addressed and integrated in the two studies.
