New Publication

The following article is now electronically available:

Árnadóttir, G. (2016) Contributing to an integrated profession: A model-based examination of the A-ONE, Scandinavian Journal of Occupational Therapy:



The article demonstrates use of Yerxa’s Model of an Integrated Profession to evaluate if three developmental cycles of the A-ONE sufficiently represented all necessary model components required for implementation into practice.


The Model of an Integrated Profession depicts a circular scholarly process whereby ideas formed in practice are subjected to research and then returned to practice through education. This knowledge generating cycle supports occupational science and the development of professional identity.
