Afternoon all,
I've been running a longitudinal follow-up study to assess outcomes following a psychological treatment for ME. As to be expected, there was a lot of drop-out by 12 months, the 5th time point of the follow-up. Usually I'd do a RM ANOVA to analyse this, but with the missing data and drop-out, it leaves my sample very small by the end, whereas it's fairly robust earlier on at earlier time points with a much better sample size. What can I do or should I be doing another test?
Thanks!
