Part of a series on early childhood demonstration programs designed to improve early parent-child relationships, stimulate positive child development, and prevent later behavior difficulties, the pamphlet describes a program in which the waiting room of a pediatric clinic for low-income families is utilized to teach parents to help their preschool children develop intellectually and emotionally. Parents visiting the pediatric clinic with children 20-30 months of age are invited to participate in the playroom program, which teaches them play skills they can use with their children at home. Those who choose to join the program are then asked to come to the playroom on a regular basis, with visits coordinated, whenever possible, with pediatric appointments. Each child initially undergoes a developmental evaluation which serves to identify cognitive handicaps requiring special medical and psychiatric services of the clinic. At subsequent appointments, the playroom trainers work individually with parents, who then use their new skills with their own children. Program aspects reviewed include the basic parent education curriculum, program staffing and staff development, and special resources and facilities. A study of children whose parents completed the program revealed apparent behavioral benefits, and showed that the children gained, on the average, 6 IQ points. (DLS)
