Moderated Mediation using Model 15 from Hayes

[Insa Linnea]

Dear all,

I am trying to do a moderated mediation analysis using Model 15 of Hayes SPSS Process. I saw a thread about Model 14 but, could someone help me with the Model 15 Stata syntax? I attached a picture of Model 15.

Best,
Insa

You didn't get a quick answer. You'll increase your chances of a useful answer by following the FAQ on asking questions. For example, I don't know how many observations you have per firm year.

You need to read the SEM model before asking questions like this. It will tell you how to do this.

I'm no expert on SEM, but I think the basic analysis would look something like this:

// https://stats.idre.ucla.edu/stata/faq/how-can-i-do-moderated-mediation-in-stata/
use https://stats.idre.ucla.edu/stat/data/hsb2, clear
rename science y  /* dependent variable   */
rename math x     /* independent variable */
rename read m     /* mediator variable    */
rename write v    /* moderator variable   */

generate xv = x*v
generate mv = m*v

sem (m <- x)(y <- x m xv mv)
estat teffects

You'll have to modify the code or add more code if you want bootstrap SEs and CIs. (See examples on this UCLA page.)

Another thing you could try is drawing the model via the SEM Builder, and having it generate the code. I suspect you'd still have to generate any needed product terms before doing that.

HTH.

Dear all,

I am analysis a moderated mediation model (model 2) using the commands in https://stats.idre.ucla.edu/stata/fa...tion-in-stata/. May I know how do I plot the moderation graph with the results obtained?

These are my results:

	Mediator	Moderation value	Path coefficient	95% confidence interval		STD error	z-value	P>|z| value
H8a	HP	Low moderator	.092	.035	.149	.029	3.14	.002
	Medium moderator	.104	.054	.153	.025	4.11	0.000
	High moderator	.116	.054	.179	.032	3.65	0.000
H8b	RBSE	Low moderator	.164	.073	.256	.047	3.51	.000
	Medium moderator	.176	.107	.245	.035	4.98	.000
	High moderator	.187	.094	.280	.048	3.82	.000

Thank you

may I ask how did you come out this table? I don't know how to perform it in STATA
