In this bibliography of NPT studies, we have included the ‘core set’ of papers, papers that document the development NPT, alongside empirical papers that draw on NPT to shape their research approach.
The first phase of developing Normalization Process Theory involved mapping the contingent (May, et al. 2003a) and normative (May, et al. 2003b) elements of embedding processes. This early work developed the concept of normalization, but did not explain how it came about.
In the second phase of development, we focused on aspects of Collective Action. This work focused on identifying and explaining the factors that promote or inhibit work to enact complex interventions in practice. First, this involved the production of a robust applied theoretical model of these factors (May 2006). This was then refined by a larger group of researchers working together (May, et al. 2007a). This theoretical model was then applied: to clinical trials (May, et al. 2007b); to mental health governance processes (Gask, et al. 2008); and telemedicine systems in practice (Finch, et al. 2007; Mair, et al. 2008). An important application of this work was by an international group led by Glyn Elwyn, who used it to develop a strong understanding of problems in the design and application of tools for shared decision-making in the clinical encounter (Elwyn, et al. 2008).
The third phase of theory development has focused on building a middle-range theory that explains how material practices (the things that people do when they operationalise complex healthcare interventions) become routinely embedded in their social contexts. The key paper here was published in Sociology in June 2009 (May and Finch 2009) and can be found here. A pdf presentation that provides an 'Introduction to Normalization Process Theory' can be found here. Other early work applied Normalization Process Theory to explaining the problems of understanding (Finch 2008) and implementing (May 2009a) telemedicine systems, and to the collective work of managing and organizing chronic illness (May 2009b). More recently, NPT has been extended towards a more general theory of implementation (May 2015).
You can also find two papers, written in Italian that you can download (see below).
