Hello, I am an Mplus newbie. Your guidance is greatly appreciated. I want to fit a 1-1-1 model (X-M-Y) with a level-1 control (c1) and a level-2 control (c2) both regressing on the Y variable. Can you please see the code below to see whether the lines related to the controls are correct? Thank you. Usevariable = ID x m y c1 c2; !c1 is an individual-level (level-1) control and c2 is a group-level (level-2) control CLUSTER = ID; within = x c1; between = c2; ANALYSIS: TYPE = TWOLEVEL RANDOM; MODEL: %WITHIN% sa| m on x; sb| y on m; sc| y on x; y on c1; %between% [sa] (a); [sb] (b); [sc] (cp); m with y; m with sa sb sc; y with sa sb sc; y on c2; sa with sb (covab); sa with sc; sb with sc; MODEL CONSTRAINT: NEW (direct indirect); indirect=a*b+covab; direct = cp; !OUTPUT: TECH1 TECH8 CINTERVAL; |

Looks right. But perhaps c2 is not unrelated to m and the s's on between. |

Dear Dr. Muthen, thank you so much for your response. I guess I am not completely sure what you mean by "But perhaps c2 is not unrelated to m and the s's on between." Would you please explain what you mean? Are you suggesting that I include the followings in the %between% statement? m sa sb sc on c2! |

Yes, for instance. |
