The Roy Adaptation Model
Sister Callista Roy proposed the Roy Adaptation Model. The person or group responds to stimuli from internal or external environment through control processes or coping mechanisms identified as the regulator and cognator (stabilizer and innovator for the group) subsystems. The regulator processes are essentially automatic, while the cognator processes involve perception, learning, judgment, and emotion. The results of the processing by these coping mechanisms are behaviors in one of four modes. These modes are the psychological-physical mode (oxygenation; nutrition; elimination; activity and rest; protection; senses; fluid, electrolyte, and acid-base balance; and endocrine function for individuals and recourse adequacy for groups), self -concept-group identity mode, role function mode, and interdependence mode. These behaviors may be either adaptive (promoting the integrity of human system) or ineffective (not promoting such integrity). The nurses assesses the behaviors in each of the modes and identifies those adaptive behaviors that need support and those ineffective behaviors that required intervention. For each of these behaviors, the nurse then seeks to identify the associated stimuli. The stimulus most directly associated with the behavior is the focal stimulus; all other stimuli that are verified as influencing the behavior are contextual stimuli. Any stimuli that may be influencing the behavior but that have not been verified as doing so are residual stimuli. Once the stimuli are identified, the nurse, in cooperation with patient, plans and carries out interventions to alter stimuli and support adaptive behaviors. The effectiveness of the action taken is evaluating, pg. 27 (George, 2011)
