1São Paulo, Brazil.
Purpose:
To test the viability of to use specialists' opinions to establish degrees of membership between nursing diagnoses and its elements (defining characteristics or risk factors), based on the concepts of fuzzy sets theory. This strategy may feasibly mapping the specialist's knowledge on the diagnostic task.
Methods:
Specialists were invited to reflect on the relationship between diagnoses and elements using linguistic variables, with a numerical representation.
Findings:
We generated four matrices of 28 diagnoses and 62 elements. Out of 905 possibilities, we identified 286 relationships, represented in graphs.
Conclusions:
The strategy was able to identify degrees of membership between nursing diagnoses and elements.
Implications:
It seems that this method, if expanded, would contribute to refining and mapping the NANDA-I terminology.
