Nursing theory also emphasizes the use of caring throughout the nursing situation and seeks to understand the persons unique context of health. Using theory nursing interventions are driven by the achievement of idealistic goals for the purpose of positive health care outcomes (Alligood 2011). However the level of a theories adaptability in practice is determined by its characteristics testability and source of development.
The functional components of Dorothea Orems Self-Care Deficit Nursing Theory (SCDNT) relates to nursings practical elements of person environment and health through the interrelated theories of self-care self-care deficit and theory of nursing systems. Orem believed the three interlocking theories expressed the clear specifications for nurse and patient roles which make up the whole that is Orems grand theory (Parker & Smith 2010 p. 125). The central idea of this theory is in which it identifies the complex relationships between the recipient of nursing care and its providers.
A key concept of this is that the patient is the principal performer of self-care behaviors not the nurse. This allows the patient to become an active agent in his or her own care and develop a sense of self-care empowerment. According to the theory goal setting should also be mutual and must consider the patients point of view. Furthermore SCDNT can be utilized as a theoretical framework to guide research in within the discipline of psychiatric nursing. This is because Orems theory links nursing interventions that promote self-care to positive patient recovery outcomes. More specifically Seed and Torkelson (2012) believe utilizing SCDNT to guide practice can provide psychiatric nurses with a language that creates a recovery model culture. In addition Orems theory brings to light nursing instrumental impact on those afflicted with mental health disparities and a means of recovery. Therefore this call to transform mental health systems is not only an opportunity for nursing to return to its roots but also deliver care that is patient-centered and conducive to healing the patient as a whole (Seed & Torkelson 2012).
