Area of Science:

  • Biostatistics
  • Medical Informatics

Background:

  • Assessing inter-rater reliability is crucial in clinical research.
  • Cohen's weighted kappa (kappa w) is a statistical measure for agreement between raters.
  • Implementing kappa w calculations can be complex.

Purpose of the Study:

  • To present a microcomputer-based program for calculating Cohen's weighted kappa (kappa w).
  • To demonstrate the utility of the kappa w program through clinical applications.

Main Methods:

  • Developed a program using Turbo Pascal and FORTRAN for microcomputers.
  • Included a typical data file, program listing, and output for user reference.
  • Applied the program to three distinct clinical scenarios.

Main Results:

  • The program provides a functional tool for computing Cohen's weighted kappa.
  • Clinical applications successfully illustrate the practical use of kappa w.
  • The provided data file and listings facilitate program replication and understanding.

Conclusions:

  • The developed software offers an accessible method for calculating kappa w.
  • This tool can aid researchers in evaluating inter-rater reliability in clinical settings.
  • The program's availability simplifies the application of weighted kappa analysis.
