The outcome criterion of the multiple logistic regression model was membership to either the stable high DRD or stable moderate DRD trajectory groups (chronic DRD). The reference group was a combined “lower risk” group (improving DRD and low DRD trajectory groups). Continuous predictors were standardized unless otherwise indicated. The model was also adjusted by using an effect-coded variable for intervention (0.5 = yes, −0.5 = no).

^aEffect-coded dichotomous variable.

^bGrand mean centered.

^*P < .05; ** P < .01.
