Scientific and Public Health Impacts of the NIEHS Extramural Asthma Research Program - Insights from Primary Data.

A conceptual model was developed to guide evaluation of the long-term impacts of research grant programs at the National Institutes of Health, National Institute of Environmental Health Sciences. The model was then applied to the extramural asthma research portfolio in two stages: (1) the first used extant data sources, (2) the second involved primary data collection with asthma researchers and individuals in positions to use asthma research in development of programs, policies, and practices. Reporting on the second stage, this article describes how we sought to broaden the perspectives included in the assessment and obtain a more nuanced picture of research impacts by engaging those involved in conducting or using the research.
