Tonge et al. [2006] used a design that allowed examination of the value added through individual coaching of parents. They compared a group that received emotional group support, and only the informational content of their combined BPT and CBT intervention but without direct coaching of parenting skills versus a group that received the full intervention, including not only didactic presentations but also coaching of skills in home settings. For parents who entered the study with elevated depressive symptoms, both groups were beneficial compared with the no treatment control. Singer et al. [1989] used random assignment to compare a group receiving intensive BPT and CBT plus case management and respite care with a group that received only case management and respite. The intensive support group had significantly lower depressive symptom scores at posttest than the comparison group, and these changes maintained in the intensive treatment group at a 1-year follow-up.
