Hi Richard, 

Thanks for your reply. As binary_mediation runs a series of regression plus it estimates the mediation direct and indirect effects, I used the -combine-catgegory. 

mim2, category(combine) est(e(effect)): binary_mediation, dv(AUDIT_lowmed) mv(peers_antisocial_bi) iv(DEP14_bi)

However, this does not produce the expected output. 

Also, when I include the bootstrap command:

mim2, category(combine) est(_b[_cons]) se(_se[_cons]): bootstrap r(indir_1) r(tot_ind) r(dir_eff) r(tot_eff), ///
reps(500): binary_mediation, dv(AUDIT_lowmed) mv(peers_antisocial_bi) iv(DEP14_bi)
I receive the following message which suggests that bootstrapping is not supported (?)

prefix bootstrap not allowed after mim

Grateful for any suggestion on how to best proceed.

Francesca

Like the message says, try using the -category- option of -mim2-. See 
the -mim2- help.
