Adherence raters will be trained using the established adherence checklists for the two study conditions. The condition supervisor will be held as the gold-standard for inter-rater reliability on adherence ratings and raters will be trained to achieve an intra-class correlation coefficient of .70 or higher, and at least 80% agreement across items. Inter-rater reliability will be checked regularly to avoid drift. Specifically, an independent adherence rater will randomly select 10% of the video-taped sessions from each condition at different treatment phases (early, mid, and late) for adherence ratings. These ratings will document the adequacy with which treatment sessions follow specific manual interventions and treatment strategies. Ratings that fall below adequacy on any dimension/component will trigger increased supervision focused for that dimension and if necessary, re-training.
