Topic 5 DQ2 Comment 3


The theory that I chose to discuss from Topics 4 and 5 is Sister Callista Roy’s Adaptation Model. The Roy Adaptation Model (RAM) presents the person as a holistic adaptive system in constant interaction with the internal and the external environment. The main task of the human system is to maintain integrity in the face of environmental stimuli. As an adaptive system, the human system is described with parts that function as unity for some purpose. Human systems include people as individuals or in groups, including families, organizations, communities, and society. Roy defined the person as the focus of nursing care, a living complex, adaptive system with internal processes (cognator and regulator) acting to maintain adaptation in the four adaptive modes (physiological, self-concept, role function, and interdependence). Adaptation leads to optimal health and well-being, to quality of life, and to death with dignity. A basic type of adaptive process, the regulator subsystem responds through neural, chemical, and endocrine coping channels. The second adaptive process, the cognator subsystem, responds through four cognitive-emotional channels: perceptual and information processing, learning, judgement, and emotion. Identifying specific processes inherent in the regulator-cognator subsystems, is not possible to directly observe the functioning of these systems. The behaviors can be observed in the four adaptive modes: physiologic- physical mode, self-concept- group identify mode, role function mode, and interdependence mode. It is through these four modes that responses to and interaction with the environment can be carried out and adaptation can be observed.
