I can't help you with the Kappa coefficient. Still, you might want to read Hayes & Krippendorff (2007) Answering the Call for a Standard Reliability Measure for Coding Data. COMMUNICATION METHODS AND MEASURES, 1(1), 77–89 arguing in favor of Krippendorff's alpha.
Follow this link for the pdf and a spss-macro for calculating alpha: http://www.afhayes.com/spss-sas-and-mplus-macros-and-code.html

Good afternoon,

I am looking to calculate Kappa to determine a measure of interrater reliability. I currently have 125 subjects being rated by different pairs of staff. Each pair assesses the same person, but there are 125 different pairs of staff. I want to calculate the overall Kappa for the entire group. I can do it for the individual pairs and average the scores, but was hoping there was a syntax/macro that I could use that would calculate the overall Kappa. The data are formatted as follows, but I can restructure the data if needed:

 

Rater1a

Rater1b

Rater2a

Rater2b

Item 1-Subject 1

Item 1-Subject 1

Item 1-Subject 2

Item 1 – Subject 2

Item 2 – Subject 1

Item 2 – subject 1

Item 2-Subject 2

Item 2 – Subject 2

 

 

Thanks

Brian
