Regression coefficients that predict constant change in ISI score in the latent change score models. (a) presents the model in which all sleep and stress reactivity indices are entered as predictors. For multicollinearity concerns (b) and (c) each presents the model has one measure of the stress reactivity to TST indices at a time (diary-measured and actigraphy-measured, respectively). Bolded are p < .05.
