This study examines the potential of adult-guided sociodramatic play for improving children's interpersonal problem-solving skills. Nineteen females and 21 males from 3 separate kindergarten classrooms participated in the study. Within each of the three classrooms, children were randomly assigned to experimental and control groups. For both groups, the experimenter acted both from outside the play group by giving suggestions, classifications, and so on, and from within the play setting by participating as a co-player. In the experimental group only, the investigator included additional behavior intended to stimulate children's problem-solving skills. Pretest and posttest scores were obtained for each child in both groups on the Preschool Interpersonal Problem Solving Test (PIPS), and adult play and problem-solving behavior were recorded on a scale developed by the author. Results indicated that adult intervention in children's sociodramatic play can increase generation of strategies for solving interpersonal problems. (Author/MP)
