Practice, research, and knowledge: contributions to the promotion of the population's health.

The papers selected for this CJNR focus issue on Health Promotion represent a broad range of topics reflecting a breadth of research methods that have been used to study (1) people’s experiences of health (Liepert et al.), (2) people’s willingness to engage in behaviour that poses health risks (O’Byrne and Watts), (3) the relative effectiveness of different approaches by health professionals to positively affect risky behaviour (Smith et al. and Black et al.), (4) the factors that enable and constrain effective partnerships between members of the so-called health-care team (Burgess), and (5) the ways in which international and federal health policies direct and restrict the ability of grassroots organizations to respond to the needs of those seeking to engage in collective actions designed to bring improvements in health at the community level. The breadth of the contributions in this special focus issue offer insight into the ways in which the topic of health promotion research has developed and evolved, and how an explicit conception of contemporary health-care practice is necessary to generate relevant knowledge for the discipline of nursing — in this field of nursing, as in all others, knowledge that is relevant for practice is intimately linked with research that is conducted within the context of clear and explicit conceptualizations of practice. This is the third time that the Journal has focused on the topic of Health Promotion, and a review of the two previous issues reveals that this message about practice, research, and knowledge has been central — although it has not always been made as explicit as it is now possible to do, given the 14 years of scholarship we have to reflect back on!
