MDC - Minimal Detectable Change

I find the concept MDC (Minimal Detectable Change) at this paper, and I looking for some package to calculate it with Jamovi.

Someone used it?

I'm not aware of MDC and haven't stumbled across it when looking at the main packages in jamvoi, and so it might not (yet) be included. However, the two sources you cited above stated that they calculated MDC according to the following (respective) formulae:
= SEM × 1.96 × √2
= SEM × z-value × √2

Accordingly - you could 'compute' these as a way to obtain the metric you are after?
