Evaluating strategies to improve careprovider performance on health and developmental tasks in an infant care facility.

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.
