Dear Linda, I have a SEM model that has regression paths from a secondorder factor to other factors. Can Mplus deal with it? How to differentiate the regression paths from the paths from the secondorder factor to its firstorder factors? Do you know any references of papers that involve this kind of complex model? Thanks! hai hong 


You can differentiate them by using the ON option. I don't know of any references.

Hello there, I'm attempting to estimate a second order factor model to capture domainspecific attitudes (firstorder) and general attitudes (second order) and then using this model to predict an outcome. I am familiar with models that can accomplish this when regressing the outcome on the second order factor exclusively. However, what I am really interested in theoretically is whether domainspecific attitudes also contribute to the outcome above and beyond general attitudes. Thus, I would like to regress the outcome on both the second order factor as well as one or more of the first order factors. Are there any references you have for this type of model and/or do you foresee any problems with this setup? 


Take a look at GustafssonBalke in MBR 1993 where these models are discussed in detail.

Hello, I just started to use MPLUS and I would like to test a model with two firstorder reflective, secondorder formative constructs (higherorder constructs) as independent variables. I would like to ask how to consider the reflective and formative thinking in the model specifications in MPLUS. Currently, I am testing the model with a code like this: MODEL: V1_DIM1 BY ind1_1 ind1_2; V1_DIM2 BY ind2_1 ind2_2 ind2_3; V1_DIM3 BY ind3_1 ind3_2 ind3_3; V1 by V1_DIM1 V1_DIM2 V1_DIM3; V2_DIM1 BY ind4_1 ind4_2 ind4_3 ind4_4 ind4_5; V2_DIM2 BY ind5_1 ind5_2 ind5_3; V2 BY V2_DIM1 V2_DIM2; V3 BY ind6_1 ind6_2 ind6_3; V3 on V1 V2; As you can see, the code does not distinguish between formative and reflective construct definitions. Could you please give me advice? Kind regards, Chris
