We noted in Chapter 3 that action research designs have been popular in nursing: for more detail on what action research involves, and why it has been seen as particularly appropriate for nursing practice, see Chapter 1 of Peter McDonnell and Jean McNiff’s book Action Research for Nurses: https://methods.sagepub.com/book/srmpromo/PDuI8U/action-research-for-nurses/i376.xml 

We suggested in Chapter 3 that designing research requires methodological coherence, such that the methods are appropriate for the question, but also a range of pragmatic requirements, such as a good ‘fit’ with the researcher.
