The Effects of Skillstreaming on the Development of Prosocial Skills in Preschool Children Teresa Andrews Pearson May 2002 The purpose of this study was to evaluate the effects of Skillstreaming as a teaching method to improve the prosocial skills of at-risk preschoolers enrolled in a Head Start Program. The four components of Skillstreaming—modeling, role-playing, performance feedback, and transfer training—provided the opportunity for preschoolers to evaluate and practice prosocial behaviors. The McGinnis and Goldstein Parent and Teacher Behavior Checklists (1990) were used to assess the preschoolers’ progress pre and post treatment. This study found significant improvement in the children’s prosocial behavior.
