title: Nursing diagnoses related to skin: operational definitions.
abstract: OBJECTIVE
  to validate the operational definitions of the defining characteristics and risk factors of the three NANDA International (NANDA-I) nursing diagnoses and to revise these diagnoses' definitions.
  
  
  METHODS
  content validation of nursing diagnosis. 146 defining characteristics and risk factors were identified in the literature in Brazilian and international databases. This was followed by content validation of the definitions of these diagnoses (presented by NANDA-I) and of the operational definitions (developed by the researchers) of the defining characteristics and risk factors, carried out by six expert nurses, regarding relevance, clarity and comprehensiveness.
  
  
  RESULTS
  of the 146 defining characteristics and risk factors, 22 were considered redundant and were excluded. The experts proposed changing the definitions of the diagnoses of Impaired Tissue Integrity and Risk for Impaired Skin Integrity. It was possible to identify various defining characteristics and risk factors which are not present in the NANDA-I taxonomy but which are indicated in the literature.
  
  
  CONCLUSIONS
  the process attained its objective of producing valid operational definitions for defining characteristics and risk factors, which will permit the undertaking of validation studies for these diagnoses. The study's contribution to advancing scientific knowledge consists in its presenting clearer operational definitions for these diagnoses and a higher number of defining characteristics and risk factors, which will assist the nurses in the identification and use of the same with greater accuracy in clinical practice.
