Latent-change-score model of the mediation channel from obesity to longitudinal changes in physiological dysregulation through perceived weight discrimination. Physiological-dysregulation-index variables at baseline (Time 1) and follow-up (Time 2) were constrained to be equal by fixing the autoregressive path to unity. The latent-change-score factor loading was fixed to 1 to capture the residual variance in dysregulation at follow-up. The rate of change in dysregulation is denoted by µΔPhysiological Dysregulation and variance in change by σ²ΔPhysiological Dysregulation. Covariates are omitted from the path diagram.
