Dear Dr. Muthen, I am currently using MPLUS to run a latent growth model that examines the impact of parental divorce on depression trajectories. Divorce will be a dichotomous time-varying predictor. I am using your paper from 1998 (Curran, Muthen, & Harford, 1998 "The Influence of Changes in Marital Status on Developmental Trajectories of Alcohol Use in Young Adults") as a guide for my model, and thus examining the time incremental change for the divorce predictor (Similar to your 'Model 2'). In the article, you state "The relation between changes in drinking trajectories and changes in marital status was modeled using techniques developed by Muthen (in preparation)". Unfortunately, I am having a hard time finding the published version of the paper that was in preparation. Would you mind pointing me in the direction of resources that will help me with how to model this?
