Holism is at the epicenter of Ericson, Tomlin, and Swain's modeling and role modeling theory. A more recent theoretical development in nursing, published in 1983, has been integrated into many different undergraduate nursing programs and clinical settings (Marriner-Tomey & Alligood, 2006). The theory, although simple in concept, has a complex combination of other well-known theories in psychology. The theory integrates Abraham Maslow's high hierarchy of needs, Erik Erickson's stages of psychosocial development, Jean Piaget's theory of cognitive development, and Selye and Engle's stress response theory (Marriner-Tomey & Alligood, 2006) . These theories cover the internal aspect of the person, which Ericson, Tomlin and Swain believe is necessary in treating the whole patient. This theory is considered a middle-range theory, however Peterson and Bredow (2009) argue that it has the necessary elements to be classified as a grand theory. Peterson and Bredow (2009) state that the theory can stand on its own just as other theories can be derived from within Modeling and Role-Modeling theory. Because Modeling and Role-Modeling theory integrates a “metaparadigm” of influences on life and health, it creates an approach to facilitate healing of the whole person (Peterson & Bredow, 2009). In its most fundamental form the theory is put into practice using two general steps, modeling and then role modeling. Modeling can be done by gaining information about how the patient perceives their health in relation to their life, allowing the nurse to see through the patient's perspective (Campbell, Finch, Allport, Erickson, & Swain, 1985). Once the nurse is aware of the patient's level of understanding of the disease, level of acceptance of the disease, stage of development... middle of the paper... processing.
