Data integration using the building technique in mixed-methods instrument development: Methodological discussion.

Mixed methods are valuable for the development of data collection instruments that are tailored to the study context and relevant for the study participants. There is limited guidance about how meaningful integration can be achieved when developing research instruments using mixed methods. We proposed a practical building technique that allows researchers to meaningfully use qualitative findings from one phase to develop an instrument for the subsequent phase. The proposed approach is useful for researchers aiming to develop data collection instruments using mixed methods.
