Logic frameworks

Developing a logical framework is an essential step in the scoping process.  It illustrates the putative causal pathways and likely positive and negative health effects for the proposed program or policy.  Logic frameworks serve three primary purposes:

  1. Organize existing knowledge
  2. Guide analyses
  3. Communicate information

A logic framework for HIA represents multiple effect pathways for the policy or project being assessed.  Each of these pathways is composed of multiple causal linkages:

Policy

e.g., tax cut

Proximate Effects

e.g., increased family, decreased gov’t revenue

Intermediate outcomes on determinants of health

e.g. education, housing, funding for publicly subsidized health care

Health Outcomes

Injury and disease rates, years of healthy life

 

Limitations

Striking the right balance between clarity and comprehensiveness is always a challenge in constructing logic frameworks for HIA.  Simpler logic frameworks may be better for communicating the analysis and for eliciting feedback, but they may over-simplify relationships and omit important intermediaries.  More comprehensive logic frameworks may be more accurate and may better represent important nuances in the analysis, but their complexity can be overwhelming and they may impede understanding when communicating to stakeholders.
