In this paper it is argued that integrative nursing research has a great potential for clarifying the theoretical perspective and substance of the nursing discipline as well as making research-based knowledge more accessible to clinical nurses. Two general kinds of integrative research are introduced and illustration provided of how these have been practiced within nursing. Significant strengths and weaknesses in current practice is highlighted. It is argued that nursing should pay more attention to this kind of research, specifically in terms of developing sound methodological approaches and overcoming the traditional schism between empirical and theoretical research. Sound integrative nursing research promises to improve the development of nursing science as well as making the products of nursing research more easily available for clinical nurses.
