Hi, 

I'm still learning the ropes of CFA and am currently  trying to (minimally) show partial tau-equivalency for a 3 -factor CFA model.  I'm conducting goodness of fit tests for 4 measurement models (congeneric, partial tau-equivalency, tau-equivalency and parallel).  

My question is whether or not I can actually specify a parallel model when an item is cross loaded on 2 factors (see motivation 1 below).  Below is how I am currently specifying the parallel model but I'm not sure this is entirely correct given the different loadings on motivation1 in the Factor 2 and Factor 3. 

Does anyone have insight as to whether nor not this is an appropriate specification? 

Thanks,
Steph
