Nursing Theories
Introduction
Theories are a set of interrelated concepts that give a systematic view of a phenomenon (an observable fact or event) that is explanatory & predictive in nature.
Theories are composed of concepts, definitions, models, propositions & are based on assumptions.
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. to select a theory for the application according to the need of the patient to apply the theory to solve the identified problems of the patient to evaluate the extent to which the process was fruitful.
Definition
Nursing theory is an organized and systematic articulation of a set of statements related to questions in the discipline of nursing.
"A nursing theory is a set of concepts, definitions, relationships, and assumptions or propositions derived from nursing models or from other disciplines and project a purposive, systematic view of phenomena by designing specific inter-relationships among concepts for the purposes of describing, explaining, predicting, and /or prescribing."
Characteristics of a Useful Theory [Robert T. Croyle (2005)]
A useful theory makes assumptions about a behavior, health problem, target population, or environment that are:
Logical
Consistent with everyday observations
Similar to those used in previous successful programs and
Supported by past research in the same area or related ideas.
Importance of nursing theories
Nursing theory aims to describe, predict and explain the phenomenon of 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. Theory is important because it helps us to decide what we know and what we need to know
It helps to
