The concept of ´homeostatis´ has guided medical research and physiological nursing research over many decades. Within homeostatis, healthy function has been defined as the return of system parameters to set points, mediated by negative or positive feedback system. Since nursing research, different from medical studies, considers both the individual and the context in which they live. Nursing approach has to be the one that is wholistic. Remarkable growth has been seen in the area of biobehavioral nursing research over the last 20 years. Many nurses are engaged in biobehavioral research that addresses questions that are either derived from clinical practice or have applicability to the clinical arena. Biobehavioral nursing often use the context of the human response model. This model considers person (vulnerability) as well as environmental (risk) factors as influencing individual responses or adaptation. Human responses are categorized as physiological, behavioral, experiential. In addition to human response model, many biobehavioral nurse scientists have embraced the study of psychoneuroimmunology (PNI) which considers the interactions among immune, nervous, and endocrine systems.
This paper is intended to provide how ´homeostatis´ concept has been evolved in nursing theory. I also intended to research how physiological concept such as ´homeostatis´, has been integrated with psycho social concept in nursing research and practice and have the implication of further biobehavioral nursing research. Nursing concept such as ´Pain´, ´Dyspnea´ have been used as examples that illustrate the diverse models as well as the significant contributions of nurse scientists to the study of biobehavioral phenomenon. All these attempts will hopefully help us in formulating a nursing theory in biobehavioral research area
