Thinking about HIA effectiveness


Washington MonumentI’m in Washington D.C. for a meeting on evaluating health impact assessment, which has been organised by the Health Impact Project at the Pew Charitable Trusts.

As part of my preparation for the meeting I’ve pulled together some of my ideas into a document, based mainly on my involvement in the Effectiveness of Health Impact Assessments in Australia and New Zealand ARC-funded project.

I’d be interested in any feedback. In particular I’d appreciate any responses to what I think remains unknown/future directions for HIA evaluation research:

  • How does HIA change perceptions at individual and organisational levels and how can we better account for this through research design?
  • How can we better evaluate learning that can occur through HIAs, at individual and organisational levels?
    • Technical
    • Conceptual
    • Social (Glasbergen, 1999)
  • How can we account for different forms of bias in evaluations of HIA?
    • Framing bias
    • Confirmation bias
    • Hindsight bias
    • Creeping determinism
    • Narrative fallacy (Harris-Roxas et al 2014)
  • How can we develop a more nuanced approach to scoping HIAs to consider the determinants of health inequities, as distinct from the determinants of health?

“What is clear here is that impact assessment is beginning to be seen not just as a tool for informing and influencing decision-makers, but as a process which changes the views and attitudes of stakeholders who engage with the process such that their own attitudes and practices change outside of the immediate decision making context. That is, the influence of impact assessment processes may extend well beyond the narrow decision window in which they operate. There is also recognition that such learning operates on an institutional and social level as well as on an individual level.” Bond & Pope (2012:4)
