Would you consider a national study exploring the sources work related stress among a headteachers, and asking them what the solutions are, participatory / action research? Due to extent of the study an suggested interventions being at a policy level, the outcomes of the research stop short of actual action but do provide a framework for it.
Perhaps rather naively, at the onset of the research, I assumed the approach (involving those impacted to create the solutions) to be participatory action research, but now I'm no longer convinced.
So the questions is, is the above action research or simply research?
