Chapter 5: Theory Development Process

THEORY DEVELOPMENT: EXISTING STRATEGIES

  1. Theory to practice to theory
  2. Practice to theory
  3. Research to theory
  4. Theory to research to theory

Theory to Practice to Theory STRATEGY
          The theorist who uses this strategy begins the process of theorizing by selecting a theory to use in practice and then uses practice to refine the theory further

Example:





Practice to Theory STRATEGY
          Keeping journals, writing notes ,reflecting in diaries, writing stories about clinical practice, talking with others, exposing our ideas for discussion, uncovering meaning, challenging assumptions, and most importantly, using critical thinking throughout these processes are methods to develop theories (Benner, 1984; Gadow,1988; Habermas, 1984).

Research to Theory STRATEGY
          The most acknowledged and accepted strategy for theory development, both by scientists in other fields as well as by many within the discipline of nursing. This strategy is built on the assumption that there is truth out there in real life that can be captured through the senses and that this truth can be verified or falsified. From this perspective, theories are referred to as scientific theories.

  • Reynolds (1971) refers to this strategy in the construction of theories as the “Baconian approach.” 
  • It is also most commonly known as the inductive method. 
  • Reynolds proposed four steps to this strategy.


Theory to Research to Theory STRATEGY
          In this strategy, theory drives the research questions and the results that answer these research questions inform and modify the theory.
Theory to Research to Theory Strategy
          THEORISTS who begin the research by defining a theory and determining propositions for testing, and then go further to modify and develop the original theories, are considered users of this strategy

The processes used for the theory to research to theory method are:

Chapter 4: Logical Reasoning

LOGIC
         -It is use and study of valid reasoning.
         -A proper or reasonable way of thinking about understanding something.
         -Is a branch of philosophy that concerns analysis of inference and arguments.

  • An inference involves forming a conclusion that is based on some evidence.
  • An argument consists of a conclusion and its supportive evidenced.
A theory may be developed through:
1. Deduction
2. Induction
3. Retroduction

DEDUCTION
  • "top-down" approach
  • A process of gaining knowledge.
  • It happens when a researcher works from the more general information to the more specific.
  • Considered to reserve truth.
                    Valid and Sound Deductive Argument
                                 Premise 1: All men are mortal
                                 Premise 2: Socrates is a man
                                 Conclusion: Socrates is mortal

                                 Premise 1: Every day, I leave for work in my car at eight o'clock.
                                 Premise 2: Every day, the drive to work takes 45 minutes. I arrive to work on time.
                                 Conclusion: Every day, Therefore, If I leave for work at eight o’clock today, I will be on time
  • No new information provides. It only rearranges information what is already known into a new statement or conclusion.
  • An important point to consider is that for a deductive argument to be sound, its premises should be true and whole argument should be valid.
                   Valid and Unsound Deductive Argument

                                Premise 1: The tennis ball is larger than the basketball. 
                                Premise 2: The basketball is larger than the golf ball.
                                Conclusion: Therefore the tennis ball is larger than the golf ball. 

                                Premise 1: All men are mortal.
                                Premise 2: Birds are men
                                Conclusion: Therefore, birds are mortal. 

                                 Premise 1: All cat have six legs.
                                 Premise 2: A tiger is a cat.
                                 Conclusion: Therefore, a tiger has six legs.
  • For it to be unsound, at least one of its premises should be false
                                 Premise 1: All victims of abuse have low self-esteem.
                                 Premise 2: Clowen has low self-esteem.
                                 Conclusion: Therefore Clowen is a victim of abuse.

                     Invalid and Unsound Deductive Argument
                                 Premise 1: All victims of abuse have low self-esteem.
                                 Premise 2: Clowen has a low self-esteem.
                                 Conclusion: Therefore, Clowen is a victim of abuse.

                                 Premise 1: Some teachers are musicians.
                                 Premise 2: All instructors are teachers.
                                 Conclusion: Therefore, all instructors are musicians.

Nursing Theories under Deductive Reasoning
  1. MYRA ESTRIN LEVINE- The Conservation Theory
  2. MARTHA E. ROGERS- Unitary Human Beings
  3. SISTER CALLISTA ROY- Adaptation Model
  4. DOROTHEA OREM- Self Care Deficit Theory of Nursing
  5. BETTY NEUMAN- Systems Model
  6. DOROTHY JOHNSON- Behavioral System Model

INDUCTION
  • "Bottom-up" approach.
  • A form of logical reasoning in which a generalized is induced from a number of specific, observed instances.
                        Premise 1:  Jennifer leaves for school at 7:00am and is on time.
                        Conclusion: Jennifer will always be on time if she will leaves at 7:00am.

                        Premise 1: All observed women in one area wear heels.
                        Conclusion: All women must wear heels. 

                        Premise 1: Victims of abuse who have been observed have low self esteem.
                        Conclusion: All victims of abused have low self esteem.
  • Allows conclusion to be false.
  • The conclusion states a generalization that extends beyond the observations.
  • Is viewed in terms of degrees of strength and probability that the premises lead to a given conclusion.

Chapter 3: History and Philosophy of Science

HISTORY AND PHILOSOPHY OF SCIENCE
“Sometimes all that is possible is to embrace the mystery, the unknown, of a situation and allow it to be beyond reach or understanding it for a while.”

The construction of nursing theories is the formalization of attempts to describe, explain, predict, or control states of affairs in nursing (nursing phenomena).

Nursing as a Science
Science is logical, systematic, & coherent way to solve problems and answer questions.
It is a collection of facts known in area and the process used to obtain that knowledge.
     •Pure or basic 
     •Natural, human, or social
     •Applied or practical

Nursing and Philosophy
Philosophy studies concepts that structure thought processes, foundations, and presumptions.
It is an approach for thinking about the nature of people, the methods that should be used to create a scientific knowledge and the ethics involved. It denotes a perspective, implying a certain broad, “taken for granted” assumptions.
     •Nature of existence
     •Morality
     •Knowledge and reason
     •Human purpose

Epistemology – a branch of philosophy that is concerned with the nature and scope of knowledge. It is referred to as the ‘theory of knowledge’
          •The power of reason and power of sensory experience (Gale)
Rationalism- the power of reason
          •Rationalist epistemology emphasizes the importance of a priori reasoning as the appropriate method for advancing knowledge.
          •Theory-then-research strategy (Reynolds)
          •Einstein made use of mathematical equations in developing his theories.
Empiricism- the power of sensory experience
          •Francis Bacon believed that scientific knowledge was discovered through the generalization of observed facts in the natural world.
          •Research-then-theory
          •Skinner’s work focuses on collection of empirical data

Early 20th Century Views of Science and Theory
  1. Philosophers focused on the analysis of theory structure, whereas scientist focused on empirical research.
  2. Positivism (imposed on the mind by experience) is the philosophy of science that information is derived from logical and mathematical treatments and reports of sensory experience is the exclusive source of all authoritative knowledge.
  3. The logical positivist believed that, empirical research and logical analysis would produce scientific knowledge.
  4. Logical empiricist argued that theoretical propositions must be tested through observation and experimentation.
  5. Emergent Views of Science and Theory in the late 20th Century
  6. Empiricists argue that for science to maintain its objectivity, data collection and analysis must be independent of a theory.
  7. Brown argues that the new epistemology challenged the empiricist view of perception by acknowledging that theories play a significant role in determining what the scientist will observe and how it will be interpreted. He identified 3 different views of the relationship between theories and observation:

  • Scientists are merely passive observers of occurrences in the empirical world. Observable data are objective truth waiting to be discovered.
  • Theories structure what the scientists perceived in the empirical world.
  • Presupposed theories and observable data interact in the process of scientific investigation.


Data-Driven, or Bottom-Up Theory- cognitive expectation are used to select input and process of incoming information from the environment.
Conceptually-driven or Top-Down Theory, asserts that incoming data are perceived as unlabeled input and  analyzed as raw data with increasing levels of complex until all data are classified.

Interdependence between Theory and Research
•A theory should be judged based on the basis of scientific consensus. 
•The acceptance of scientific hypothesis through research depends on the appraisal of the coherence of theory
•Dubin identified when scientific consensus is necessary:
       1. Agreement on the boundaries of the theory; the phenomenon it addresses and what it excludes
       2. Agreement on the logic used in constructing the theory to further understanding from a similar perspective
       3. Agreement that the theory fits the data collected and analyzed though research

Issues in Nursing Philosophy and Science Development
  • Meleis characterized the years of progress in nursing in four stages:

     1.Practice
     2.Education and Administration
     3.Research 
     4.Development of Nursing Theory
  • Peplau developed the first theory of nursing practice in her book, Interpersonal Relations in Nursing.
  • Journal of Nursing Research (1952)
  • 1960s and 1970s – analysis and debate on he metatheoretical issues related to theory development
Four fundamental patterns of knowledge in Nursing (Carper, 1978)
     1.Empirical knowledge (nursing science)
     2.Esthetic knowledge (nursing as an art)
     3.Moral knowledge (ethics in nursing)
     4.Personal knowledge (therapeutic use of self)

1980s further acceptance of nursing theory and its incorporation in the nursing curricula; publication of several nursing journals

Postpositivism focuses on discovering the patterns that may describe a phenomena.
Interpretive paradigm tends to promote understanding by addressing the meanings the participants social interaction that emphasize situation, context and multiple cognitive constructions that individuals create on everyday events.
Critical paradigm for knowledge development in nursing , provides framework for inquiring about the interaction between the social, political, economic, gender and cultural factors and experiences of health and illness.

Florence Nightingale: Environmental Theory


CREDENTIALS AND BACKGROUND
·         Born on May 12, 1820 while her parents were in extended European tour.
·         Named after her birthplace Florence,Italy.
·         Parents: Edward and Frances Nightingale
·         Elder sister: Parthenope Nightingale
·         The Nightingale’s, they were well-educated, wealthy, aristocratic Victorian family.
·         During her childhood, her father educated her much more broadly and rigorously than other young women of her time.
·         Nightingale was tutored on mathematics, languages, religion, and philosophy (these later influenced the course of her work.)
·         Living in Victorian aristocratic activities and social events during her adolescences, she also developed the sense that her life should become more useful.


                THE JOURNEY STARTS
·         Year 1837, She wrote “God spoke to me and called me to his service” a diary about her calling. Although unclear for some time, she understood that she was called to become a nurse.
·         Year 1851, she got accepted at Kaiserworth, Germany (a protestant religious community with a hospital facility) after completing the 3months training.
·         Upon returning to England, she began examine hospital facilities, reformatories and charitable institutions.
·         Year 1853, Two years after the training, she became the superintendent of the hospital for invalid gentlewomen in London.


                THE CRIMEAN WAR CAME
·       Sidney Herbert (a family friend and Secretary of war) requested her to go to Scutary, Turkey to provide trained nurses to care for wounded soldiers.
·         Year 1854 November she arrived at Scutary, Turkey. In providing nursing care, she addressed the environmental problems; these were lack of sanitation and presence of filth (few chamber pots, contaminated water, contaminated sheets and blankets, and overflowing cesspools). In addition, the soldiers were faced with exposure, frostbite, lice infestation, and other opportunistic diseases during recovery.
·         She improved these deplorable (awful) conditions that made her popular and revered to the soldiers but the support of the physician and military officers was less than enthusiastic.
·         She was called “The Lady with the Lamp”, as immortalized in the poem “Santa Filomena” by Henry Wadsworth Longfellow. Because she made her rounds during the night.
·         In Scutary, she became critically ill with Crimean Fever, which might have been typhus or brucellosis.
             
                 MISSION FULFILLED, RETURNING HOME
·         Nightingale returned to England for great accolades, to Royal family (Queen Victoria) and the soldiers who had served in the Crimean War.
·         She was awarded funds in recognition of her work; she used it to establish a teaching institution for nurses at St. Thomas Hospital and King’s College Hospital in London.
·         Within few years, her school began receiving requests to establish new schools at hospitals worldwide. Florence Nightingale reputation as the founder of modern nursing was established.
·         She devoted her life to some social issues and causes in attempt to create social change. She continued to concentrate on army sanitation reform, and functions of army hospitals, sanitation in India and sanitations and healthcare of the poor in England.
·         June 1869 to June 1870, Nightingale’s Writings: 1. Notes on Matters affecting the Health, Efficiency, and Hospital Administration of the British Army, 2. Notes on Hospitals, 3. Report on Measures Adopted for Sanitary Improvements in India.
·         Shortly after returning to England, she was confined to her residence, citing her continued ill health.
·         August 13 1910 with an age of 90, Florence Nightingale died in her sleep.

Environmental Theory
a.        Define nursing as “What nursing has to do… is to put the patient in the best condition for nature to act upon him. Nursing ought to signify the proper use of fresh air, light, warmth. Cleanliness, quiet, and proper selection and administration of diet.
1.       Human Beings- humans in relations to the environment and the impact of the environment on them.
2.       Environment- physical environment focusing on ventilation, warmth, noise, light and cleanliness.
3.       Health- pathology teaches the harm disease has done: Health is positive; pathology is negative.
4.       Disease is a reparative process or nature’s way to remedy a process of poisoning or decay.
b.      Her theory focused on the control of the environment of individuals needing nursing care
Ø  Air
Ø  Health of houses
Ø  Ventilation and warming
Ø  Light
Ø  Minimal noise
Ø  Cleanliness
Ø  Appropriate nutrition
Ø  Variety
Ø  Beddings
Ø  Chattering hopes

c.       Goal of Nursing: to assist client to stay in balance; to decrease the unnecessary energy expenditure.

d.      Nursing Action: manipulate environment to compensate for client’s response to it.


MAJOR ASSUMPTIONS
Nursing:
Is having the responsibility for someone’s health. On her writing “Note’s on Nursing” provided guidelines on how to provide nursing care and how a nurse should think.
Person:
Is a patient needed to enhance the development of the recovery and this patient have the preferences. However, Nightingale gave emphasis on nurses as was in control of the patient environment.
Health:
Is being well and able to use the power to the fullest. Nightingale envisioned the environmental control to maintain health and prevention of diseases through her environmental theory.

Environment:
“Those elements external to and which affect the health of the sick and healthy person. Everything from the patient food and flowers to the patient’s verbal and nonverbal interactions with the patient.”

CRITIQUE
Simplicity
                The theory is simple. In Nightingales theory, there are three major relationships. 1. Environment to nurse, 2. Nurse to environment, and 3. Nurse to patient. Nightingale believes that the environment is a big factor in creating disease while the disease is the reaction to the person based on the environment. So Nightingale emphasized the importance of environment in preventing disease. Preventing diseases through the manipulation of environment and to enhance the recovery of a person. There is no proof that Nightingale intended to develop a theory but it is clear that nightingale intended to give meaning in science and art of nursing and to provide general rules for nursing care improvement for the patient.
Generality
                Nightingales theory remains relevant and the universality and timelessness also remains pertinent. Nightingale concept about the relationship of nurse to patient and importance of environment for the person recovery remain applicable today. These meet the criterion of generality.
Empirical Precision
                Concepts and relationships within Nightingale’s theory are frequently stated implicitly and are presented as truths rather than tentative, testable statements. She also suggests a role of qualitative and phenomenological research methodology in nursing as she were addressing the development of the art of nursing.
Derivable Consequences
                By Nightingales writings, with an unexpected, her writings directed the nurse to action on behalf of the relationship of nurse to patient. This directive encompasses the areas of practice, research and education. She viewed nursing as a divine calling as being a nurse is doing the will of God. On her environmental manipulation and psychological care of patient is applicable in contemporary nursing settings.

Chapter 2: “Significance of Theory for Nursing as a Discipline and Profession “

Nursing Theoretical Works represents
The most comprehensive ideas
And systematic knowledge about nursing;
Therefore theory is vital to both
The discipline and the profession.

Discipline is specific to academia and a branch of education, a department of learning or field of knowledge.
Profession refers to specialized field of practice, which is founded upon the theoretical structure of the science or knowledge of that discipline and the accompanying practice abilities. 

Significance of theory for nursing as a discipline

1.       University baccalaureate programs proliferated, masters programs in nursing were developed, and the curricula began to be standardized through the accreditation process.
2.       Attention to the importance of nursing conceptualizations for the research process and the role of a conceptual framework in the purpose and design of research production of science and nursing theoretical works also began to publish.
3.       Works began to be recognize for their theoretical nature, such as Henderson, Nightingale and etc.
4.       KEYNOTE ADDRESS, New nursing doctoral programs were beginning to open and they reopened the discussion of the nature of nursing science. This becomes the first classic reference for nursing as discipline and for distinguishing between the discipline and profession.
5.        Fawcett’s conceptualization of metaparadigm of nursing and unifying conceptual-theoretical structure of knowledge recognize works of major nursing theorist as conceptual framework and paradigms of nursing.
6.       MAJOR SIGNIFICANCE IS;THE DISCIPLINE IS DEPENDENT UPON THEORY
6.1. Theoretical works have taken nursing to a higher level.
6.2. The emphasis has shifted from a focus on knowledge about how nurses function, which concentrated on the nursing process, to focus on what  nurses know and how they use knowledge to guide their thinking and decision making while concentrating on the patient. 

Significance of theory for nursing as a profession

Clearly, nursing is recognize as a profession today.
1.       Bixler and Bixler published a set of criteria tailored to nursing in the American Journal of Nursing in 1959. They stated that a profession:
a.       Utilizes in its practice a well-defined and well-organized body of specialized knowledge that is on the intellectual level of the higher learning.
b.      Constantly enlarges the body of knowledge it uses and improves its techniques of education and service by the use of the scientific method.
c.       Entrusts the education of its practitioners to institution of higher education.
d.      Applies its body of knowledge in practical services that are vital to human and social welfare.
e.      Functions autonomously in the formulation of professional policy and in the control of professional activity thereby.
f.        Attracts individuals of intellectual and personal qualities who exalt service above personal gain and who recognizes their chosen occupation as a life work.
g.       Strives to compensate its practitioners by providing freedom of action, opportunity for continuous professional growth and economic security.
These criteria have historical value because they provide an understanding of the developmental path the nursing followed.
2.       Nursing theory is a useful tool for reasoning, critical thinking, and decision making in nursing practice.
3.       Nursing theoretical works provide a perspective of the patient.
4.       Nursing theory provides more direction for nursing practice.
5.       The conceptual models of nursing are comprehensive and the reader to the specifics of the practice.
6.       Middle range theories contain the specifics of nursing practice.

Lydia E. Hall: Core, Care and Cure Model

 
Lydia Eloise Hall
1906-1969

BACKGROUND
ü  Lydia Hall began her prestigious career in nursing as a graduate of the York Hospital School of Nursing in York, Pennsylvania.
ü  She earned B.S. and M.A. degrees from Teachers College, Columbia University, in New York.
ü  Had faculty position at the York Hospital School of Nursing and Fordham Hospital School of Nursing
ü  Became consultant in Nursing Education to the Nursing Faculty at the State University of New York, Upstate Medical Center. She also was an instructor of nursing education at Teachers College.
ü  Career Interests: Public Health Nursing, cardiovascular nursing, pediatric cardiology and nursing of long term illness.
ü  Authored 21 publications and the bulk of the articles and addresses regarding her nursing theory were published in in the early to middle 1960s.
ü  In the 1967, she received the award for Distinguished Achievement in Nursing Practice from Columbia University.
ü  Greatest Achievements:              Hall design and develop Loeb Center for Nursing at Montefiore Hospital in New York City and apply her theory to nursing practice. Opened at January 1963. A 80 bed capacity for persons aged 16 years or older who were no longer having acute biological disturbances. Patients were recommended by their physicians and had favourable potential for recovery and subsequent return to their community. Hall served as administrative director of the Loeb Center for Nursing for from its opening until her death in February 1969.





CONCEPTS

Behavior
Hall broadly defines behavior as everything that is said or done. Behavior is dictated by feelings both conscious and unconscious

Reflection
Reflection is a Rogerian method of communication in which selected verbalizations of patients is repeated back to them with different phraseology to invite them to explore feelings further.

Self-awareness
Self-awareness refers to the state of being that nurses endeavor to help their patients achieve. The more self-awareness a person has of their feelings, the more control they have over their behavior.
Second-Stage illness
The patient enters the second phase of medical care once the doctors begin giving only follow up care. Hall defines second-stage illness as a nonacute recovery phase of illness. This stage is conducive to learning and rehabilitation. The need for medical care is minimal, although the need for nurturing and learning is great. Therefore this is the ideal time for wholly professional nursing.

Wholly Professional Nursing
Wholly Professional Nursing implies nursing care given exclusively by professional registered nurses, educated in the behavioral sciences who take the responsibility and opportunity to coordinate and deliver the total care of their patients. This concept includes the roles of nurturing, teaching and advocacy in the fostering of healing.


CENTRAL CONCEPTS

Care
Care alludes the “hands on”, intimate bodily care aspect of nursing of the patient and implies a comforting, nurturing relationship. While intimate physical care is given, the patient and the nurse develop a close relationship representing the teaching and learning aspect of nursing. The natural and biological sciences (the Body).
q  Nurturing component of care
q  It is exclusive to nursing
q  “Mothering”
q  Provides teaching

and learning activities
q  Nurses goal is to “comfort” the patient
q  Patient may explore and share feelings with nurse
q  Nurse is concerned with intimate bodily care
q  Nurse applies knowledge of natuaral and biological sciences
q  Nurse act as potential comforter

Core
        Core involves the therapeutic use of self in communicating with the patient. The nurse through the use of reflective technique helps the patient clarify motives and goals, facilitating the process of increasing the patients self awareness. The social sciences (the person).
q  Patient care is based on social sciences
q  Therapeutic use of self
q  Helps patient learn their role is in the healing process
q  Patient is able to maintain who they are
q  Patient able to develop a maturity level when nurse listens to them and acts as sounding board
q  Patient able to make informed decisions
q  Emphasis on social,emotional,spiritual and intellectual needs
q  Patient makes more rapid progress towards recovery and rehabilitation

Cure
Cure is the aspect of nursing involved with the administration of medications and treatments. The nurse functions in his role as an investigator and potential cause of pain related to skills such as injections and dressing changes. Seeing the patient and family through the medical care aspect of nursing. The pathological and therapeutic sciences (the disease).
ó  Care based on pathological and therapeutic sciences
ó  Application of medical knowledge by nurses
ó  Nurse assisting the doctor in performing tasks
ó  Nurse is patient advocate in this area
ó  Nurse is a patient advocate
ó  Nurses role changes from positive quality to negative quality
ó  Medical surgical and rehabilitative care
ó  COPERATE WITH FAMILIES OR CARE GIVERS

INTERACTIONS:
q  Emphasis placed on the importance of total person
q  Importance placed on all three aspects functioning together
q  All three aspects interact and change in size


Theoretical Assertions

1.  Nursing functions differently in the three interlocking circles that constitute the aspects of the patient. These three circles are interrelated and are influenced by each other. The three circles are: the patient’s Body, the Disease affecting the body, and the Person of the patient, which is affected by each of the other circles. Nursing operates in all three circles, but it shares then with the other professions to different degrees. Pathological conditions are treated with medical care (Cure); therefore nursing shares this with the physicians. The Person aspect (Core) is cared for by therapeutic use of self. Therefore this area is shared with psychiatry, psychology, social work, and religious ministry. The body of the patient is cared for exclusively by nursing (Care). The Care circle includes all intimate bodily care such as feeding, bathing, and toileting. The care component is the exclusive domain of nursing.

 2. Hall’s second assertion relates to the Core postulate of her theory. As the patient needs less medical care, he or she needs more professional nursing care and teaching. This inversely proportional relationship alters the ratio of nursing care in the three circles. Patients in the second stage of illness (nonacute phase) are primarily in need of rehabilitation through learning; therefore the Care and Core circles predominate the Cure circle.

 3.  The third assertion of the theory is that wholly professional nursing care will hasten recovery. Hall descried the concept of team nursing, which gives the care of less complicated cases to caregivers with less training. Nurses are complex people using a complex process of teaching and learning in caring for complex patients with complex diseases. Only professional nurses are inherently qualifies, to provide the teaching, counseling, and nurturing needed in the second stage of illness.


Assumptions and the Paradigm of Nursing

Nursing
        Nursing is identified as consisting of participation in the care core and cure aspects of nursing care. Nursing can and should be professional. Hall stipulated that patients should be cared for only by professional nurses who can take total responsibility for the care and teaching of their patients. Care is the sole function of the nurse, where as core and cure are shared with other member of the health team. However the major purpose of care is to achieve an interpersonal relationship with the individual that will facilitate the development of care.
       
Person
        Hall viewed a patient as composed of these three aspects: body, pathology and person. She emphasized the importance of the individual as unique, capable of growth and learning and requiring a total person approach. Patients achieve their maximal potential through learning process, therefore, the chief therapy they need is teaching.

Health
        Hall viewed becoming ill is a behavior. Illness is directed by feelings-out-of-awareness, which are the root of adjustment difficulties. Healing may be hastened by helping people move in the direction of self-awareness. Once people are brought to terms with their true feelings and motivations, they become free to release their own powers of healing. Through the process of reflection, the patient has the chance to move from the unlabeled threat of anxiety . . . through a mislabeled threat of phobia or disease . . . to a properly labeled threat (fear) with which he can deal constructively.

Environment
        The concept of environment is dealt with in relation to the individual. Hall was credited with developing the concept of Loeb Center for Nursing because she assumed that the hospital environment during the treatment of acute illness creates a difficult psychological experience for the ill individual. Loeb Center focuses on providing an environment conducive to self development in which the action of nurses is for assisting the individual in attaining a personal goal.


Limitations

·         Hall’s theory of nursing has a limited generality. Hall’s primary targets are the adult patients who have passed the acute phase of his or her illness and have a relatively good chance of rehabilitation. This concept severely limits the application of the theory to a small population of patients of specific age and stage of illness. The theory would be most difficult to apply to infants, small children and comatose patients.
·         The function of the nurse in preventive health care and health maintenance is not addressed nor is the nurses’ role in the community health, even though the model could be adapted.
·         Hall viewed the role of nurses as heavily involved in the care and core aspects of patient care. Unfortunately, this concept provides for little interaction between the nurse and the family, because her theory delineates the family aspect of patient care in the cure circle.
·         The only communication technique Hall described in her theory as means to assist patient to self awareness was reflection. This is very limited approach to therapeutic communication because not all nurses can effectively use the technique of reflection and it is not always the most effective and most successful communication tool in dealing with patients.
