Jan 3, 2023 at 23:04 comment added Jeffrey Girard @LarissaCury There are different formulations of the ICC that answer different questions. One of these formulations, often called ICC(C,k), is equivalent to Cronbach's alpha. But the other formulations will differ.

Nov 15, 2022 at 19:46 comment added Larissa Cury thank you, @Spatzle, I've just read the chapter of the material you've recommended. Things are clearer now. Authors mention that Cronbach's α is a special case of ICC, but this is not clear to me yet, I've seen elsewhere that they'd be the same thing, I'm a bit confused. Any thoughts? Concerning correlation, as far as I'm concerned, the 'consistent' approach would equal Pearson's rho, right?
