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:

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
