What are the key differences between embedded, transformative, and multiphase mixed methods research designs?

Embedded, transformative, and multiphase mixed methods research designs are three distinct approaches within the field of mixed methods research. While they share some similarities, they also have key differences in terms of their goals, timing, and integration of qualitative and quantitative data.

Embedded mixed methods research design involves the sequential or concurrent collection and analysis of both qualitative and quantitative data, with one method being subordinate to the other. In this design, one method is embedded within the other, meaning that either qualitative or quantitative data plays a supporting role in the overall research process. The purpose of embedded design is to provide a more comprehensive understanding of the research topic by triangulating different types of data. For example, a researcher may collect qualitative data through interviews and then use quantitative data to validate or further explore the findings.

Transformative mixed methods research design, on the other hand, aims to go beyond simply combining qualitative and quantitative data. It seeks to create a transformative impact on the research participants, the researcher, and the broader society. This design emphasizes the integration of qualitative and quantitative data at all stages of the research process, from the formulation of research questions to data collection, analysis, and interpretation. The goal is to generate new knowledge that challenges existing assumptions and leads to positive social change. Transformative design often involves collaboration with stakeholders and may require a longer time frame to achieve its objectives.

Multiphase mixed methods research design involves conducting multiple phases of research, each with its own distinct qualitative or quantitative focus. These phases can be sequential or concurrent, and the design allows for the integration of findings from each phase to provide a more comprehensive understanding of the research topic. The purpose of multiphase design is to address different aspects or dimensions of the research question, with each phase building upon the previous one. For example, a researcher may start with a qualitative phase to explore the experiences and perspectives of participants, followed by a quantitative phase to measure the prevalence or impact of certain factors identified in the qualitative phase.

In summary, embedded mixed methods research design involves one method being subordinate to the other, transformative design aims to create a transformative impact on participants and society, and multiphase design involves conducting multiple phases of research to address different aspects of the research question. Each design has its own unique goals, timing, and integration of qualitative and quantitative data, allowing researchers to choose the most appropriate approach based on their research objectives.
