Dear Ariel,

Thanks for this.

I'll follow up on these references and let you know how I make out.

Best regards,

Edward

Hi Edward,

Take a look at the following UCLA website:

http://www.ats.ucla.edu/stat/stata/faq/ml_mediation.htm

I also strongly suggest you read the recent paper by Zhang et al., which
highlights some of the problems when performing multilevel mediation
analysis. There are additional concerns when the either the mediator or
outcome variables are binary, and some commentators suggest rescaling (see
for example, Krull and MacKinnon). Others have argued that this rescaling
does not solve the problem and that the potential outcomes approach is more
appropriate (see Imai et al.). I have not seen any more recent literature on
the multilevel models with binary mediators/outcomes, or potential outcomes
approaches with multilevel data.

I hope this helps

Ariel

Subject: st: mediation analysis with multi-level logit models

Hello,

I am interested in carrying out a mediation analysis with a multi-level
logit model. I am using 'xtmelogit' on Stata 11.0 for Mac. My level-2 IV is
continuous and the DV and level-1 mediators are binary. I am aware of the
Stata program

'binary-mediation' for single level logit models. The bootstrap command is
used to compute the standard errors for the direct and indirect effects. Is
there a program for multi-level logit models?

Thanks for any help on this.
