Growing Wild Cornwall was recently involved in the ‘In Residence Scheme’ at the European Centre for the Environment and Human Health.  We have had an opportunity to investigate some of the psychological benefits to people of outdoor play and have been examining ways in which these benefits can be effectively evaluated.  We have looked at a wide range of measures and seek to use a validated combination of scales and templates to measure change and show outcomes in terms of health, well being and natural connectedness. We now have a range of quick and easy to use measures which can show the progress that young people are making.
