Subject:Longitudinal Analysis using PLS3 and BDI scores for children as dependent vars

Dear All, I am using the NSCAW data to examine the developmental indicators, especially BDI-Cognitive and PLS3, for infants (0-12 months at wave 1) through the 4 waves of data collections. One thing that baffles me is that the BDI and PLS3 standard scores for most children at the 2nd wave have dropped precipitously from the baseline wave when they were under 12 months. This may indicate the poor performance of these infants relative to the national norm. I wonder whether the (un)reliability of the baseline scores should also be a contributing cause. I would appreciate your opinions / comments on this. I plan to adopt growth curve modeling in analyzing the development trajectories of these infants using BDI and PLS3 scores as dependent variable. Is it preferable to use the Standard Scores or the raw scores as the dependent variables? Is it valid to use the raw scores as the dependent variable since items included in the instrument at different waves are not the same? Your advice is appreciated.
