Hi, I'm afraid I've gotten myself into something a little over my head.....
I have a study with two groups (patient, therapist) who were scored by 3 raters using a nonverbal coding system. For simplicity let's say the coding system has 3 ratings (positive, neutral, negative). These categories were assessed at 2 time points (high, low). What would be the best way to analyze this data? Specifically I'd like to know if there is a significant difference between the high and low conditions (taking each group seperately). I'd also like to know if there is an interaction between time point and rating. I tried using a simple two factor anova but my data is not independent, as the same people are scored in both conditions. I have done several analyses using simple paried t-test, but am at a loss as to what my next step should be. Would a repeated measures anova be appropriate? Any suggestions or references would be much appreciated!!
