Mental health: what do we know, how did we find it out and what does it mean for nurses?

In recent years service providers, practitioners and academics have all moved away from the term mental illness in favour of mental health. At the same time nurses have been increasingly asked to go beyond work aimed at the alleviation or reduction of mental illness and to actively promote mental health. Such a perspective acknowledges that those who experience mental illness can equally experience and have the potential for mental health. In this paper we review key works from within psychology and health promotion (including medical sociology) that have shed light on the factors that influence mental health in its positive sense. Throughout the review we are careful to reflect on the role that research methods have played in constructing our current understanding of mental health. The aim of the review is to provide nurses with the knowledge that is necessary to undertake the challenge of promoting mental health in a practical but also reflective way.
