This study introduces an expert systems approach for validating nursing models, enhancing research clarity. The Nine-Stage Schematic offers a structured method for defining and clarifying nursing knowledge models.

Area of Science:

  • Nursing Science
  • Information Systems
  • Engineering

Background:

  • Nursing research increasingly utilizes models to represent complex relationships.
  • Model validation is crucial for ensuring the rigor and applicability of nursing research findings.
  • Existing validation methods may benefit from structured, systematic approaches.

Purpose of the Study:

  • To propose and illustrate the expert systems approach for validating nursing models.
  • To adapt a seven-step expert systems validation process into a Nine-Stage Schematic.
  • To clarify and define models within the discipline of nursing through a robust validation method.

Main Methods:

  • Adapting a seven-step expert systems validation process from engineering and information systems.
