Taxonomic Validation: An Overview

Abstract
A valid taxonomy legitimizes the elements that make up the taxonomy and increases trust in its generalizability and predictability. There is a concern that the NANDA Taxonomy is not a valid taxonomic structure. Despite on-going work to validate individual nursing diagnoses, there is little research that focuses on validation of groups of diagnoses (taxons) within the NANDA taxonomy. This last article in a series of four will familiarize the readers with why, what, and how a taxonomy of nursing diagnoses can be validated. This article highlights assessment of the validity and reliability of a taxonomy, compares the process of taxonomic validation to the research process, and explores examples of validation design.
