In this video, I demonstrate how to conduct a structural equation modeling (SEM) analysis in AMOS. As SEM is based on confirmatory factor analysis (CFA), I would suggest you watch the following videos:

Thanks for the video sir. I noticed you said one would need to confirm the 4 constructs in separate models while it’s my understanding that it’s the overall model fit that is a requirement for SEM. In most papers I’ve come across the author has calculated the model fit indices for the entire model rather than reporting it for each latent variable separately. The composite reliability and convergent and discriminant validity are of course calculated separately for each factor. I may have misinterpreted what you’ve said so any comment or clarification is much appreciated. Best regards.

The composite reliability and convergent and discriminant validity should be reported, but also the fit of the measurement models, too. Examining the fit of measurement models is not commonly done, but it would be pretty important to carry out that step.

This absolutely improves the model fit, but the model is the same and the items are the same. If we report the statistics, what are the differences between the original model and the updated model drawing covariances? I appreciate your help if you could answer these questions. Thank you.

Covariances could indicate local dependence (bad news for the model) if they are between errors of items on different factors. On the other hand, covariances between factors indicate an association between them.

First, build one CFA per each latent variable. So, in your case, build 8 independent CFA and run the analyses separately. Once you are sure they work fine, include them all in the final SEM analysis.

Hello Dear, wanted your advise regarding the following issue I am facing. When there is no covariance amongst the the independent / exogenous constructs (when i don’t draw it), the model fit is poor. But when the covariance line is drawn among the independent construct the model fit becomes excellent. In your video also the model 2 depicted a better result than model 1. What are the difference between these model? Based on which model's result should state my model fitness.

Shouldn’t those values be different?

@@salmapapia9737 IF the model without covariances is a poor fit, then it is a wrong model. but you should still report this in your paper.

Hi Dr, This is Alex, a research assistant from Malaysia. I have a question about this SEM. Before that, thank you for your excellent and helpful video! I am currently looking at a construct of a model and there are a few predictors that are dichotomous and dummy variables, so my question will be can SEM incorporate dichotomous and dummy variables in the estimation? Thank you, Dr.

Yes, you can. Please watch the video on MIMIC SEM analysis. I have explained how these variables can be used in SEM analysis. kzbin.info/www/bejne/jGWaZHaZpLt0rNk

​@@VahidAryadoust Thank you so much, Dr. I have another question. I just estimated my model and my Chi-square is significant. Theoretically, it should not be significant. However, my GFI, AGFI, CFI, and RMSEA showed that my model is fit. So, does this imply my model is still fit on the data given the Chi-square is significant? Thank you Dr.

@@alextan806 the Chi-squared index in SEM is sensitive to sample size. I would rely on CFI, and TLI (NNFI) and RMSEA, plus normed chi-squared (X^2/df < 3).

@@VahidAryadoust Yes, there are some arguments saying that Chi-squared is sensitive to sample size where a large sample size will lead to significance in the test, I have 5000+ observations and I think this explains why the Chi-squared becomes significant. Thank you, Dr. Your video is so helpful and I really learned a lot from your video~
