The authors present an analysis of the concept of communication, and propose a revision of NANDA's taxonomic human response pattern communicating, and its nursing diagnosis, impaired verbal communication. The authors recommend that the definitions of the human response pattern and its diagnosis be modified to incorporate facets other than verbal emissions. The addition of new defining characteristics and related factors also should be considered. New defining characteristics could include modifications of criteria of the American Speech and Hearing Association, highlighting disturbances in speech, language, hearing, and vision in addition to some of the present NANDA defining characteristics. Proposed related factors are classified as alterations in human patterns (developmental, physiological, psychological, social, cultural and environmental).
