Thanks, Dr. Crowson. This is EXTREMELY helpful. I would say your video is better than a 10-week lecture in school. A follow-up question, sometimes I see researchers will control for covariates in the mediation model. For example, when examining the mediating role of interest between mastery and achieve, I want to control age, education, and income level (variable names: age, edu, income) . How should I do this? Thanks in advance!

Hi there. Thanks for your question. I noticed that I did not include any covariates in my example, but I would expect it to work the same by adding in the covariates when using the sem command. I just gave it a run through and it worked. Try: sem (achieve

Thank you for this! I have a question on interpretation I hope you can help me with: How do I interpret a complete negative mediation where path a is negative and path b positive? STEP 1 - (X -> M) with B=-0.608 and p=0.000 STEP 2 - (M -> Y) with B=6.826 and p=0.004 STEP 3 - (X -> Y) with B=4.715 and p=0.443 As STEP 1, STEP 2 and the Sobel's test above are significant and STEP 3 is not significant the mediation is complete!

If your model contains control variables, i.e., covariates, you must include these in each of the sem equations. Thus, your sem model will look something like this: sem (MV

What about control variables in medsem stata?. How can we include in medsem syntax. Or it automatically bases on sem syntax being a post mediation.

Hello Dr.Crowson! thank you for this amazing video! I just have one question. For example 1, which only has 3 variables, should I report the goodness of fit(chi-square)? I did it and the dof is 0 and p>chi2 was just a dot (.). I assumed dof was because I had 3 pathways having literally all possible paths :) Thank you so much in advance!

Hi, Dr. Crowson. great video! I have a question about your medium command. If you have a moderated mediation situation, in which, say the independent variable is mastery, the moderating variable is anxiety, the mediator is interest, and the dependent variable is achieve, then would you say that the "indep" category in medsem command is the interaction term of mastery*anxiety. So, medsem, indep(mastery*anxiety) med(interest) dep(achieve) mcreps(500) rit rid Is this correct?

In the last example, there are 2 parallel mediators (interest and anxiety) however, medsem only includes choosing "interest" as the mediator. How can we put 2 mediators there?

Hi Mark. Great video! How do I obtain confidence intervals (CIs) for the direct and total effects after medsem? Medsem only provides CIs for the indirect effect. However, I cannot use the estimates and CIs from the sem model, because the medsem posthic estimation provides estimates and CIs from Monte Carlo simulations.

@mikecrowson2462

Hi there. It's been awhile since I have worked with this package, but I don't recall there being anything related to subgroups analysis. Here's some documentation on the package I found on the web: ntnuopen.ntnu.no/ntnu-xmlui/bitstream/handle/11250/2589997/offprint-medsem+a+Stata+package+for+statistical+mediation.pdf?sequence=1 If your aim is to test a model in say Group A and then in Group B, you could subset out your data for each group and then run your model on each using the medsem package. If your question is about invariance between groups, then that's another matter entirely as that is clearly not what medsem is designed to get at. I hope this helps!

Hi there. Thanks for your question. There is no way to test a mediation analysis where you have a binary DV or mediator using the medsem package. I've written a do-file that would allow you to test for mediation where the mediator is continuous but the dependent variable (Y) is binary. If you go to the video here (kzitem.info/news/bejne/xYme2KGCpYxei5g), you can download the do-file and the video walks you through its use. Apart from that, I don't know of any other packages or do file (not saying they aren't out there, just that I don't know of any). Your only other option is to write your own code to accomplish this. That's kind of what I ended up doing to create my do-file. There is actually a more efficient way to do it than how I did (I was trying to mimic Hayes' Process macro through SPSS) and that is to run a generalized SEM and then use the stored regression coefficients to compute the indirect effect. You'd also bootstrap the indirect effect to generate the confidence interval. There are a couple of nice tutorials here (stats.idre.ucla.edu/stata/faq/how-can-i-do-mediation-analysis-with-the-sem-command/) and here (stats.idre.ucla.edu/stata/faq/how-can-i-do-moderated-mediation-in-stata/) that I pivoted off of when writing my code. You could probably just extend this from sem (which is what they demonstrate) to generalized sem. This is probably way more than you wanted to know. Good luck
