The Institute for Work & Health has developed a model for describing and measuring the impacts of its research. Based on this model, the Institute tracks and documents case studies that describe three different types of impact:
Type 1 case study: Evidence of the diffusion of research
The degree to which IWH research is noticed and referred to by external stakeholders in the occupational health and safety system―e.g. policy-makers, health and safety associations, employer groups, unions, clinicians and workplaces―in their own deliberations and information vehicles.
Type 2 case study: Evidence of research informing decision-making
The degree to which IWH research is acted upon by external stakeholders in developing and changing legislation, policies, directives and programs that have an impact (often through intermediaries) on workplaces, as well as the degree to which evidence-based practices suggested by IWH research are taken up directly by workplaces or clinicians.
Type 3 case study: Evidence of societal impact
The degree to which IWH research contributes to improvements at the societal level, including changes in: work injury/illness rates; workers’ compensation and other insurance claims, durations and costs; healthy workforce outcomes; and population health status.
This last level of impact, Type 3, is hard to measure because of issues surrounding attribution (the degree to which a societal impact can be clearly attributed to research) and time lag (the length of time it takes for research findings to get published, noticed, acted upon and have an effect).
