Some really interesting questions about the role of context have been coming up in discussions about applying NPT. Elizabeth Murray and colleagues have undertaken an important systematic review of implementation studies that points to the shaping effects of different aspects of implementation contexts. The big question is how to integrate 'action' and 'context' in studies. Mandy Stijnen and colleagues at Maastricht have done a really nice job in a recently published paper that describes a complex intervention to improve health-related quality of life and reduce disability among potentially frail community-dwelling older people in the Netherlands. Importantly, they show how NPT constructs were used to frame specific research questions. It's pretty cool, so check it out.
I'm really interested in the ways that we understand action in context - the fundamental social science question that I'm interested in is about how we understand the dynamics of human agency in conditions of constraint - and I'm contemplating hosting an expert seminar on this topic in 2015.
