Note. Four coded predictors were entered into hierarchical linear models (see Table 3) to model data from the eight assessment timepoints.
5mFU = RCT five-month post-randomization follow-up; 8mFU = RCT eight-month post-randomization follow-up; Mid = Mid-intervention = Pre-intervention; Post = Post-intervention, see Methods for timing.
