They are derived through two principal methods; deductive reasoning and inductive reasoning. Objectives to assess the patient condition by the various methods explained by the nursing theory to identify the needs of the patient to demonstrate an effective communication and interaction with the patient. Definition Nursing theory is an organized and systematic articulation of a set of statements related to questions in the discipline of nursing. Croyle ] A useful theory makes assumptions about a behavior, health problem, target population, or environment that are:
Models are representations of the interaction among and between the concepts showing patterns. Models allow the concepts in nursing theory to be successfully applied to nursing practice. They provide an overview of the thinking behind the theory and may demonstrate how theory can be introduced into practice, for example, through specific methods of assessment.
Propositions Prepositions are statements that explain the relationship between the concepts. Process Processes are series of actions, changes or functions intended to bring about a desired result.
During a process one takes systemic and continuous steps to meet a goal and uses both assessments and feedback to direct actions to the goal. A particular theory or conceptual frame work directs how these actions are carried out.
The delivery of nursing care within the nursing process is directed by the way specific conceptual frameworks and theories define the person patientthe environment, health and nursing. It should provide the foundations of nursing practice, help to generate further knowledge and indicate in which direction nursing should develop in the future Brown Theory is important because it helps us to decide what we know and what we need to know Parsons It helps to distinguish what should form the basis of practice by explicitly describing nursing.
This can be seen as an attempt by the nursing profession to maintain its professional boundaries. Following theories are basic to many nursing concepts. It describes how to break whole things into parts and then to learn how the parts work together in " systems". These concepts may be applied to different kinds of systems, e.

Evaluating Scientific Theories Russell Berg has fifteen criteria for scientificness and he knows how to use them. The ‘scientific method’ is a group of methods and procedures. To identify the current status of theory evaluation in nursing and provide directions for theory evaluation for future development of theoretical bases of nursing discipline. Background Theory evaluation is an essential component in development of nursing knowledge, which is a critical element in development of nursing discipline. How general is the theory? That is, how widely applicable is it? In most cases, a theory that may only be applied within a fairly narrow set of circumstances is not considered as useful as a theory that encompasses a very wide range of communicative interactions. The ideal, of course, is a theory.
Adaptation is a continuously occurring process that effects change and involves interaction and response. Human adaptation occurs on three levels: Developmental Theory It outlines the process of growth and development of humans as orderly and predictable, beginning with conception and ending with death.
The progress and behaviors of an individual within each stage are unique. The growth and development of an individual are influenced by hereditytemperament, emotional, and physical environment, life experiences and health status.

To use communication to help client reestablish positive adaptation to environment. Stress reduction is goal of system model of nursing practice. This adaptation model is based on the physiological, psychological, sociological and dependence-independence adaptive modes. Identifies specific phenomena through abstract concepts.
It identifies explicit goals and details how these goals will be achieved. School of thoughts in Nursing Theories Need theorists.The definition for use here is one adapted from Meleis () and states that a nursing theory is a conceptualization of phenomena and relationships in or pertaining to nursing for the purpose of describing, explaining, predicting and/or prescribing nursing care.

Course Competencies: Thoughtfully evaluate ways of knowing in class discussions.
4. Analyze the role of inductive & deductive thinking in theory development. Theory evaluation is an essential component in development of nursing knowledge, which is a critical element in development of nursing discipline. Despite earlier significant efforts for theory evaluation in nursing, a recent decline in the number of theory evaluation articles was noted and there have been few updates on theory evaluation in.
Theories and models of nursing practice Introduction: Nursing theory provides a perspective from which to define the what of nursing, to describe the who of nursing (who is the client) and when nursing is needed, and to identify the boundaries and goals of nursing’s therapeutic activities.
