Mark, you will need a column for each coder and construct. e.g.,
Construct1_Coder1, Construct1_Coder2, Construct1_Coder3,
Construct2_Coder1, etc. The rows will be the tapes or tape segments. The
ICC allows you to examine all 3 coders simultaneously, not just as
pairwise comparisons.

Subject: How to run an ICC in SPSS 15.0
I apologize if this is too broad a question, but I need to run an ICC to
check on inter-rater reliability between three coders rating multiple
constructs (listening to therapy tapes).
I set up the dataset so each coder is a nominal variable.
Some constructs are given a rating of 1 (low) to 5 (high).
Some constructs are pure behavioral counts (e.g. how many times did the
therapist do behavior X).
When I run the ICC, I'm just entering two variables at a time: coder and
the
variable of interest. Is this correct?
Any thoughts? thanks! marc
