Establishing mixed method research design guidelines in health impact assessment investigations

Abstract

In the last decade local policymakers and community health officials have been using a Health Impact Assessment (HIA) strategy to assess the health impacts of their policy decisions. The HIA research design is founded on the mixed method research approach (integration of quantitative and qualitative data slices within a single investigation) to get as comprehensive assessment as possible of the expected impacts. The HIA literature has yet to provide any guidelines on how community health investigators should conduct a mixed-method HIA research. We conducted a content analysis of 100 HIAs executed around the world published between 1999 and 2011 and analysed their research methodologies. Observations generated from the analysed HIAs were used to establish an ‘HIA mixed method model’ by which a series of mixed-method design guidelines were used to help community health researchers improve the analytical capabilities in their future HIA investigations.
