Hi,
I have 2 variables with the same 5 level ordinal rating of  suicidality.
I have the variable derived from a survey of visitors to a psychiatric
emergency clinic and another variable derived from the psychiatrist's
clinical note after they evaluated the study participant. I know that
the survey results and the psychiatrist's notes are not independent
since they are rating the same entity-the study participant.
I am using a combination of methods to examine agreement including:
looking at the crosstabs for patterns, calculating proportion of
agreement, ICC, and McNemar.
I understand that modeling (specifically conditional logistic
regression) can be used and thus potential confounders can be examined.
I don't understand what would actually be entered into a conditional LR
model?
Here is an example of a crosstabs for the total sample (n=377)
  Participant rating                   MD rating
                                    No SI   Passive SI   Active SI
Plan   Plan prep
No SI                             177          50                21
        31         18
Passive SI                          1            6                  3
             9           2
Active SI                             0           1                  9
          11          5
Plan                                    0           0
0             9           9
Plan prep                            0           0                  1
           2          12

Thanks for any help,
Jan
