Middle Range Theory
Theory’s responsibility is to provide nurses with standards that reinforce practice, as well as, for future nursing understanding and delivery. Basically, it provides nursing professionals with a tested way of thought on how to handle certain situations with proven results. The importance of nursing theories to nursing research is the knowledge offered gives nurses the foundation for communicating with others and best practice. Middle range theory according to McEwen & Wills (2011, p 35) are theories that have concrete concepts, that are specific, incorporate a measured number of concepts and characteristics of the real world and are tested for accuracy.
Beck’s Approach to Theory Development
Becks approach to theory development in regard’s to postpartum psychosis, postpartum depression and maternity blues, is a grounded theory, which is a process of theory identification that allows the researcher the information to explain the general features of an issue, while establishing a theory. Beck started by reviewing existing literature on maternity blues. Reflecting on characteristics of postmodern philosophy of science. Beck believed, as reported by Lasiuk & Fergusson (2005) “Each successive research project should be guided by the previous research study. The object of this systematic, continuous inquiry is the cumulative production of new knowledge in a substantive area of nursing.” By looking at all available research Beck was able to get a complete understanding of maternal blues from the information she gathered.
Beck went on to formulate a mothers attempt to cope with postpartum depression and identified four stages: Stage one, encountering terror, stage two, dying of self. Stage three, struggling to survive. Finally, stage four, regaining control. She identified predictors of postpartum depression and interventions to help treat new moms.
System theory looks at the system as a whole, nurses are taught early on to treat the patient as a whole person not just a disease or illness. This can also include caring for families or caregivers of the patients. According to McEwen & Willis, (2011 p, 254). For survival, a system must achieve a balance internally and externally.”
Beck believed that depression was the cause of one view of ones self. Essentially, moods and negative feelings actually precede and are the cause of depression. She was able to contribute to the practice of nursing trough her investigation into postpartum depression. By understanding the concepts beck set out to learn she in turn developed a model to help educate patients, families and the nursing profession.
Example of Middle Range Theory that doesn’t contain Conceptual Model
Patient Care Experienced may not be Patient Care Delivered
Characteristics of middle range theory are that they are not comprehensive, but narrowly focused, they make generalizations across settings and specialties, they have a limited number...
