Hi Dr. Geiser. Thanks for this really informative tutorial. I am wanting to expand on this model to also include a predictor and mediating variable. I have repeated the steps outline above in order to estimate change and TAU1 for the mediator and am trying to regress change in y on change in m and x however, my model won't converge. I have included bootstrap = 1000 in the analysis command in line with your recommendations on mediation and moderation analysis. I have also included starts = 1000 and the best LL appears to have been replicated but Mplus still will not calculate S.E.'s. Have you any suggestions?

Thanks in advance

Thanks for the clear tutorial. One question. Since indicators from time 1 and time 2 are all loaded to tau 1, is it still reasonable to treat tau 1 as initial score? I think tau 1 represents a overall latent score combining two timepoints indicators.

Hi Dr. Geiser, one more question. Do you think it is necessary to examine the model invariance at two timepoints before conducting latent change score analysis? Thanks.

Thanks for all the great videos! I am new to Mplus. My two main variables are both binary... would I still be able to use LCS?

Amazing videos! Is it possible to do cross level latent change score models? Say I am interested in the change of individual conflict, but also wondering if team level predictors may influence the change. Is there a way to do that? Thank you so much!

Great Videos! Are you familiar with latent congruence model (Cheung, 2009) in Mplus? If so, could you make a tutorial video! Thanks a lot!
