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.

Taxonomic development in nursing, although still in its infancy, is progressing. Taxonomy development has moved beyond subjective placement of diagnoses into categories based on an "expert" opinion alone. The taxonomy of nursing diagnoses is entering a new era whereby the assumptions and classification rules for Taxonomy I--Revised are being investigated. Alternative taxonomic structures require careful scrutiny and comparison to establish whether one structure will meet the needs of the profession or whether multiple structures of nursing diagnoses relative to outcomes are required. As members within the discipline become more sophisticated in approaches to taxonomic development, methods of handling taxonomic problems, such as varying levels of abstraction and taxonomic affinity, will be discerned.
