ABSTRACT
Responding to administrative staff and parental concerns, using modified reversal and withdrawal designs, two experiments evaluated a staff-managed feedback system to improve the hygiene and developmental skills of children in an infant/toddler center. Experiment 1 examined feedback designed to increase staff performance in checking and changing diapers, and recording those changes. A chart plus supervisory feedback produced increases in and maintenance of staff performance. Experiment 2 compared an existing staff management system with a "playchart" plus feedback in increasing careprovider-infant stimulation. The data (with follow-up on a new staff) supported the use of the new feedback system. Questionnaire data further supported the utility of the playchart system.
