Dear Drs. Muthen, I am using SEM to test a model with 3 IVs (X1-X3), 2 mediators (M1, M2, both at the same level), and 2 DVs(Y1-Y2). I want to see if M1 and M2 have full mediating effects. For the Mplus code, I just wrote: X1 BY ****; *********** *********** Y2 BY ****; Y1 Y2 ON M1 M2; M1 M2 ON X1 X2 X3; Y1 Y2 ON X1 X2 X3; Model Indirect: Y1 IND M1 X1; ************; Y2 IND M2 X3; But how could I tell if the high correlation, if any, between M1 and M2 would compromise the results I ended up with? Would journal reviewers have problems with this? Thanks!!!! |

You may have a problem with multicollinearity in Y1 Y2 ON M1 M2; |

Hi Dr. Muthen, Thanks for the response. So, should I write instead as follows: Y1 Y2 ON M1; Y1 Y2 ON M2; thanks!! Tony |

There is no difference between the two specifications. |

So, would it be meaningful if I controlled for the correlation of M1 and M2? |

I know of no way to deal with multicollinearity other than not to use both variables at the same time. |

Dr. Muthen, Thanks for your response!! I will give a second thought on my model.... Thanks!! Tony |
