Hi Samran,

> I was wondering, if I get significant differences in the interaction, how can I do the post-hoc tests to identify which treatment made the difference, and if the pre-sessions are similar?

If I understand your design correctly, then these would just be paired
t-tests (Post vs Pre within Placebo; Post vs Pre within Active;
Placebo vs Active within Pre; Placebo vs Active within Post).
