title: Statistical Characteristics of the Weighted Inter-Rater Reliability Index for Clinically Validating Nursing Diagnoses.
abstract: OBJECTIVE
  To analyze the statistical characteristics of the weighted inter-rater reliability index for validating nursing diagnoses.
  
  
  METHODS
  From a computational algorithm, the index values were compared with the sample size, frequency of the clinical indicator, number of agreements between raters, and three other agreement estimators.
  
  
  RESULTS
  The index moderately correlated with the frequency of the clinical indicator and strongly correlated with the number of agreements and disagreements between the raters. This index showed a poor correlation with sample size.
  
  
  CONCLUSIONS
  This index selects those clinical indicators with high frequency and/or absolute agreement and therefore has a high sensitivity.
  
  
  CONCLUSIONS
  The high sensitivity may result in incorporating false positive clinical indicators.
