Over the last two decades there has been an increasing interest in well-being as a focus of policy, practice and research. There is general agreement that well-being takes a more holistic approach and focuses not simply on the absence of illness. In its constitution, the World Health Organisation defines health as ‘a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity’. However, the concept of well-being still remains poorly defined and frequently appears to be used at a superficial level as ‘health and well-being’ to cover a wide range of concepts.
