I'm looking to study eudaimonic happiness in secondary school settings and think its a reasonable gap in research. If you know of any publications that get into this please let me know!
We have done some studies on orientations to happiness of primary a, but never published it. I wasn't satisfied with the scale - I'm not sure it is appropriate for young people, especially the meaningful life items (which could be considered as eudaimonia). I an not aware of any other studies with children.
See my article about the arts, education and well being. I claim that first there is a change in discourse and negoation of the meanings involved. Gradually, the words turn to action and someday eudaimonia might be an important recognised part of education.
