I am trying to compare the change in score of inhaler technique in the same group of patients at different time points:
- before counseling
- 1 week after counseling
- 2nd week of counseling
I have scored the technique using an 8 item checklist. Each step performed correctly is scored
1 and each step performed incorrectly is scored
What is a suitable test to use in this case? Would a repeated measures ANOVA work? If not, which test should I use?
