This study used a multiple baseline with reversal design to assess whether visual performance feedback (VPF) influenced targeted and nontargeted staffs' use of behavior-specific praise (BSP) in a day-treatment program. This study expands on the typical VPF audience and assesses whether VPF can be effective with noncertified staff in a day-treatment program for young children with behavior disorders, an environment in which it is difficult to maintain high rates of BSP. In previous school-based studies, VPF has been collected by researchers and provided to targeted teaching staff. In the current study, rather than relying on researchers, the authors used staff instructors to collect VPF and assessed how that experience influenced the instructors' use of BSP. Results suggest that VPF provided, on average, a doubling in rates of BSP use by directly targeted staff and more than a 50% increase in rates of BSP in nontargeted instructors who collected BSP data. Furthermore, three of the four participants had substantially higher praise-to-correction ratios during the VPF intervention when compared with baseline and reversal conditions. Implications for improving treatment fidelity and reducing supervision time are discussed. (Contains 1 table and 2 figures.)
