I have a growth curve estimated with five timepoints. I want to know for which timepoints growth was significant. To do this, I have run the model five times with different time scores as shown below. I can then obtain the estimate (SE) for each time period (from 0 to 1). I would prefer not to run five separate models  how can timepoints be evaluated within a single model in Mplus? i s q  y1@0 y2@1 y3@2 y4@3 y5@4; !i s q  y1@1 y2@0 y3@1 y4@2 y5@3; !i s q  y1@2 y2@1 y3@0 y4@1 y5@2; !i s q  y1@3 y2@2 y3@1 y4@0 y5@1; !i s q  y1@4 y2@3 y3@2 y4@1 y5@0; 


You need only use one model and then use Model Constraint to express the differences in modelestimated means (see Topic 3 of our course handouts) between each time point.
