I am doing an MSc dissertation looking at how the health of women experiencing homelessness is affected by a disparate set of international, national and state laws and policies. This is a scoping review to set the stage and demonstrate the complexity, hence I am not analysing a particular policy and its outcomes. It crosses many disciplines and government ministries and is by nature difficult to measure outcomes or attribute causality which is part of what I'm trying to show. I'm struggling to find a theory / framework to use to present this in a coherent manner. Is policy mapping appropriate here? Any more thoughts?
