Biography of Callista Roy
Sister Callista L. Roy (born October 14, 1939) is a nursing theorist, professor, and author. She is known for her groundbreaking work in creating the Adaptation Model of Nursing.
Education and Career
Callista Roy received her Bachelor of Arts Major in Nursing from Mount Saint Mary’s College in Los Angeles in 1963 and her master’s degree in nursing from the University of California in 1966.
After earning her nursing degrees, Roy began her sociology education, receiving both a master’s degree in sociology in 1973 and a doctorate in sociology in 1977 from California.
During her time working toward her master’s degree, Roy was challenged in a seminar with Dorothy E. Johnson to develop a conceptual model for nursing. Roy worked as a pediatric nurse and noticed a great resiliency of children and their ability to adapt to major physical and psychological changes. Impressed by this adaptation, Roy worked towards an appropriate conceptual framework for nursing.
She developed the model’s basic concepts while she was a graduate student at the University of California from 1964 to 1966.
In 1968, she began operationalizing her model when Mount Saint Mary’s College adopted the adaptation framework as the nursing curriculum’s philosophical foundation.
Roy was an associate professor and chairperson of the Department of Nursing at Mount Saint Mary’s College until 1982 and was promoted to the professor’s rank in 1983 at both Mount Saint Mary’s College and the University of Portland. She helped initiate and taught in a summer master’s program at the University of Portland.
She was a Robert Wood Johnson postdoctoral fellow at the University of California, San Francisco, from 1983 to 1985 as a clinical nurse scholar in neuroscience. During this time, she researched nursing interventions for cognitive recovery in head injuries and the influence of nursing models on clinical decision making.
From 1987 to the present, Roy began the newly created resident nurse theorist position at Boston College School of Nursing, where she teaches doctoral, master’s, and undergraduate students.
In 1991, she founded the Boston Based Adaptation Research in Nursing Society (BBARNS), which would later be renamed the Roy Adaptation Association.
Roy’s other scholarly work includes conceptualizing and measuring coping and developing the philosophical basis for the adaptation model and nursing’s epistemology.
Roy belongs to the Sisters of St. Joseph of Carondelet.
Adaptation Model of Nursing
Sr. Callista Roy’s Adaptation Model of Nursing was developed by Sister Callista Roy in 1976. The prominent nursing theory aims to explain or define the provision of nursing. In her theory, Roy’s model sees the individual as a set of interrelated systems that maintain a balance between these various stimuli. The adaptation Model of Nursing is discussed further below.
Sr. Callista Roy has numerous publications, including books and journal articles, on nursing theory and other professional topics. Her works have been translated into many languages all over the world.
Roy and her colleagues at Roy Adaptation Association have critiqued and synthesized the first 350 research projects published in English based on her adaptation model.
Her most famous work is on the Roy adaptation model of nursing.

Callista Roy’s Adaptation Model of Nursing
The Adaptation Model of Nursing is a prominent nursing theory aiming to explain or define the provision of nursing science. In her theory, Sister Callista Roy’s model sees the individual as a set of interrelated systems that maintain a balance between various stimuli.
The Roy Adaptation Model was first presented in the literature in an article published in Nursing Outlook in 1970 entitled “Adaptation: A Conceptual Framework for Nursing.” In the same year, Roy’s Adaptation Model of Nursing was adapted in Mount St. Mary’s School in Los Angeles, California.
Roy’s model was conceived when nursing theorist Dorothy Johnson challenged her students to develop conceptual models of nursing during a seminar. Johnson’s nursing model was the impetus for the development of Roy’s Adaptation Model.
Roy’s model incorporated concepts from Adaptation-level Theory of Perception from renowned American physiological psychologist Harry Helson, Ludwig von Bertalanffy’s System Model, and Anatol Rapoport’s system definition.
First, consider the concept of a system as applied to an individual. Roy conceptualizes the person in a holistic perspective. Individual aspects of parts act together to form a unified being. Additionally, as living systems, persons are in constant interaction with their environments. Between the system and the environment occurs an exchange of information, matter, and energy. Characteristics of a system include inputs, outputs, controls, and feedback.
- Systems of matter and energy progress to higher levels of complex self-organization.
- Consciousness and meaning are constructive of person and environment integration.
- Awareness of self and environment is rooted in thinking and feeling.
- Humans, by their decisions, are accountable for the integration of creative processes.
- Thinking and feeling mediate human action.
- System relationships include acceptance, protection, and fostering of interdependence.
- Persons and the earth have common patterns and integral relationships.
- Persons and environment transformations are created in human consciousness.
- Integration of human and environmental meanings results in adaptation.
- Persons have mutual relationships with the world and God.
- Human meaning is rooted in the omega point convergence of the universe.
- God is intimately revealed in the diversity of creation and is the common destiny of creation.
- Persons use human creative abilities of awareness, enlightenment, and faith.
- Persons are accountable for the processes of deriving, sustaining, and transforming the universe.
Major Concepts of the Adaptation Model
The following are Callista Roy’s Adaptation Model’s major concepts, including the definition of the nursing metaparadigm as defined by the theory.
“Human systems have thinking and feeling capacities, rooted in consciousness and meaning, by which they adjust effectively to changes in the environment and, in turn, affect the environment.”
Based on Roy, humans are holistic beings that are in constant interaction with their environment. Humans use a system of adaptation, both innate and acquired, to respond to the environmental stimuli they experience. Human systems can be individuals or groups, such as families, organizations, and the whole global community.
“The conditions, circumstances and influences surrounding and affecting the development and behavior of persons or groups, with particular consideration of the mutuality of person and health resources that includes focal, contextual and residual stimuli.”
The environment is defined as conditions, circumstances, and influences that affect humans’ development and behavior as an adaptive system. The environment is a stimulus or input that requires a person to adapt. These stimuli can be positive or negative.
Roy categorized these stimuli as focal, contextual, and residual. Focal stimuli are that confront the human system and require the most attention. Contextual stimuli are characterized as the rest of the stimuli present with the focal stimuli and contribute to its effect. Residual stimuli are the additional environmental factors present within the situation but whose effect is unclear. This can include previous experience with certain stimuli.
“Health is not freedom from the inevitability of death, disease, unhappiness, and stress, but the ability to cope with them in a competent way.”
Health is defined as the state where humans can continually adapt to stimuli. Because illness is a part of life, health results from a process where health and illness can coexist. If a human can continue to adapt holistically, they will maintain health to reach completeness and unity within themselves. If they cannot adapt accordingly, the integrity of the person can be affected negatively.
“[The goal of nursing is] the promotion of adaptation for individuals and groups in each of the four adaptive modes, thus contributing to health, quality of life, and dying with dignity.”
In Adaptation Model, nurses are facilitators of adaptation. They assess the patient’s behaviors for adaptation, promote positive adaptation by enhancing environment interactions and helping patients react positively to stimuli. Nurses eliminate ineffective coping mechanisms and eventually lead to better outcomes.
Adaptation is the “process and outcome whereby thinking and feeling persons as individuals or in groups use conscious awareness and choice to create human and environmental integration.”
The regulator subsystem is a person’s physiological coping mechanism. The body attempts to adapt via regulation of our bodily processes, including neurochemical and endocrine systems.
The cognator subsystem is a person’s mental coping mechanism. A person uses his brain to cope via self-concept, interdependence, and role function adaptive modes.
Four Adaptive Modes
The subsystem’s four adaptive modes are how the regulator and cognator mechanisms are manifested; in other words, they are the external expressions of the above and internal processes.
Physical and chemical processes are involved in the function and activities of living organisms. These are the actual processes put in motion by the regulator subsystem.
This mode’s basic need is composed of the needs associated with oxygenation, nutrition, elimination, activity and rest, and protection. This model’s complex processes are associated with the senses, fluid and electrolytes, neurologic function, and endocrine function.
Self-Concept Group Identity Mode
In this mode, the goal of coping is to have a sense of unity, meaning the purposefulness in the universe, and a sense of identity integrity. This includes body image and self-ideals.
Role Function Mode
This mode focuses on the primary, secondary, and tertiary roles that a person occupies in society and knowing where they stand as a member of society.
This mode focuses on attaining relational integrity through the giving and receiving of love, respect and value. This is achieved with effective communication and relations.
Levels of Adaptation
The various modes and subsystems meet the needs of the environment. These are usually stable processes (e.g., breathing, spiritual realization, successful relationship).
The cognator and regulator are challenged by the environment’s needs but are working to meet the needs (e.g., grief, starting with a new job, compensatory breathing).
The modes and subsystems are not adequately meeting the environmental challenge (e.g., hypoxia, unresolved loss, abusive relationships).
Six-Step Nursing Process
A nurse’s role in the Adaptation Model is to manipulate stimuli by removing, decreasing, increasing, or altering stimuli so that the patient.
- Assess the behaviors manifested from the four adaptive modes.
- Assess the stimuli, categorize them as focal, contextual, or residual.
- Make a statement or nursing diagnosis of the person’s adaptive state.
- Set a goal to promote adaptation.
- Implement interventions aimed at managing the stimuli.
- Evaluate whether the adaptive goal has been met.
As one of the weaknesses of the theory that applying it is time-consuming, applying the model to emergencies requiring quick action is difficult to complete, the individual might have completed the whole adaptation process without the benefit of having a complete assessment for thorough nursing interventions.
Adaptive responses may vary in every individual and may take a longer time compared to others. Thus, the span of control of nurses may be impeded by the time of the patient’s discharge.
Unlike Levine, although the latter tackled adaptation, Roy focused on the whole adaptive system itself. Each concept was linked with the coping mechanisms of every individual in the process of adapting.
When an individual presents an ineffective response during his or her adaptation process, the nurses’ roles were not clearly discussed. The main point of the concept was to promote adaptation, but none were stated on preventing and resolving maladaptation.
Strengths of the Roy’s Adaptation Model
- The Adaptation Model of Callista Roy suggests the influence of multiple causes in a situation, which is a strength when dealing with multi-faceted human beings.
- The sequence of concepts in Roy’s model follows logically. In the presentation of each of the key concepts, there is the recurring idea of adaptation to maintain integrity. Every concept was operationally defined.
- The concepts of Roy’s model are stated in relatively simple terms.
- A major strength of the model is that it guides nurses to use observation and interviewing skills in doing an individualized assessment of each person. The concepts of Roy’s model are applicable within many practice settings of nursing.
- Painstaking application of the model requires a significant input of time and effort.
- Roy’s model has many elements, systems, structures, and multiple concepts.
