Proposed bivariate latent change score model of proximal negative life events (LEs) and percent heavy drinking days (PHD). m = month; L1–L5 = latent change score for proximal LEs; H1–H5 = latent change score for PHD; αu=constant change coefficient for PHD; αl = constant change coefficient for proximal LEs; βu= proportion change coefficient for PHD; βl= proportion change coefficient for LEs; γl = bivariate change coefficient for LEs regressed on PHD; γu= bivariate change coefficient for PHD regressed on LEs. Distal negative LEs and other pre-treatment factors predicting the initial latent slopes for both proximal LEs and PHD are not depicted in this model.
