From practice to midrange theory and back again: Beck's theory of postpartum depression
This article presents a brief overview of theory as background for a more detailed discussion of midrange theory-its origins, the critical role for midrange theory in the development of nursing practice knowledge, and the criteria for evaluating midrange theory. We then chronicle Cheryl Tatano Beck's program of research on postpartum depression (PPD) and advance the thesis that her theory of PPD, titled Teetering on the Edge, is an exemplar of a substantive midrange nursing theory. We demonstrate Beck's progression from identification of a clinical problem to exploratory-descriptive research, to concept analysis and midrange theory development, and finally to the application and testing of the theory in the clinical setting. Through ongoing refinement and testing of her theory, Beck has increased its generalizability across various practice settings and continually identifies new issues for investigation. Beck's program of research on PPD exemplifies using nursing outcomes to build and test nursing practice knowledge.

- "Additionally , such an approach is desirable when direct explanation and application to practice is desired for organizational phenomena in a particular context (Earley, 2006; Richardson , 2004). Multiple disciplines, including nursing (Lasiuk & Ferguson, 2005), accounting (Richardson, 2004), international business (Earley, 2006), and strategic management (Jemison, 1981), have recognized the need for middle-range theory to better inform our understanding of how to manage employees within complex subpopulations and contexts and to contribute to the advancement of a discipline by providing new perspectives . The complexities of the IT workforce as described in previous sections, and the resulting challenges they produce both in practice and research, portray a subpopulation that may benefit from research using this theoretical perspective.

ABSTRACT: Over the past several decades, nurses have been increasingly theorizing about the relationships between culture, health, and nursing practice. This culture theorizing has changed over time and has recently been subject to much critical examination. The purpose of this paper is to identify the challenges impeding nurses' ability to build theory about the relationships between culture and health. Through a historical overview, I argue that continued support for the essentialist view of culture can maintain a limited view of complex race relations. I also argue that attempts to apply culture theory, without knowledge of important historical, political, and economic factors, has often resulted in oversimplified versions of what was originally intended. Furthermore, I argue that individual-level interventions alone will be insufficient to address health inequities related to culture. Despite new critical conceptualizations of culture and the uptake of cultural safety, nursing scholars must better address the broader organizational, population, and political interventions needed to address inequities in health. I conclude with suggestions for how nurses might proceed with culture theorizing given these challenges.

ABSTRACT: This paper presents a middle-range theory of psychological adaptation in death and dying that was abstracted from a series of quantitative and qualitative studies. The findings from these studies are described, a conceptual definition for end-of-life psychological adaptation is given, evidence is synthesized into a limited number of assumptions, testable hypotheses are derived, and the constructed middle-range theory is linked to the conceptual-theoretical framework of the Roy adaptation model.
