I am trying to run a SEM to see the causal relationship among latent variables. I ran the CFA and SEM using Amos, but I realized that the model is very complicated since one factor, which I originally thought to be unidimensional, is two-dimensional, and that makes the model look very messy. Since that factor is not derived from a theoretical background, it seems hard to force to use it as unidimensional. Also, a construct validity test also indicated that the factor is two-dimensional.
I know that creating parcels and running the path model has lots of limitations, such as not including error, and it is not necessarily used to create a parsimonious model, but I want to compare whether there are any big differences between CFA and a model with item parceling.
I saw lots of articles that have debated item parceling, but couldn't find how to conduct item parceling in Amos. How can I conduct item parceling in Amos? Thanks!
