[R-meta] P-values one or two-sided

Dear all,

I am working with the Metafor package using the rma.mv function.

I read that, by default, the p-values are reported for two-sided tests, so I am wondering whether I should divide my p-values by two.

I am asking about the test of moderators specifically (when performing the Q-test of Moderation).

Similarly, when removing the intercept (i.e putting a -1 behind the moderator) I assume that p-value is not two-sided?

I am just not sure how much of the output is depending on R default and how much is part of the Metafor package and how exactly it is set up.

Thanks for clarifying.

Kind regards,
