I have a case reading instrument with 120 items. Most of the items have three answer choices, but some have two and some have four. There is also one with five. We did an inter-rater reliability study with five readers reading the same case. I haven't looked at the data yet, but I'll need to soon. I was going to use Cohen's Kappa, which is available in SPSS. I was going to set up the data file so that similar items--related topic areas with the same number of answer choices--were treated as separate cases, analogous to a set of MRIs, Xrays, etc. rated by different clinicians, as I've seen in a number of articles. I'm not entirely happy about this approach because the content for the items may not be similar enough. Also, it doesn't allow me to identify items that are troublesome.

Can anyone see a better way of testing for interrater agreement with this type of data?

Thanks,

Henry
