The influence of environmental factors on physical activity and generalisability of public health research
Much of Public Health's investment in interventions is informed by research that has taken place in other areas outside of the area that is to be invested. Using physical activity as an example, Watts et al (2011) highlight some of the issues involved in adopting this approach. In their paper they present a framework to enable practitioners to consider the influence of environmental factors when assessing the generalisability of research to a particular place or location.
