This paper reports on the effectiveness of the Realistic Parenting Skills program, an intervention program for parents of preschoolers designed to influence children's religious education which was field tested at 7 sites in Ohio. Subjects were 37 families and their 3- to 5-year-old preschoolers. Seven group meetings were conducted for parents at each site under the leadership of experienced personnel. Data about the program were collected at the completion of the 7 group meetings held in the winter, and again at posttest in June or July. The winter data (leader and parent ratings of different aspects of the program) indicated leader and parent reactions to the program, while the summer data (parent ratings of their children on the 7 scales of Self-Regard) gave evidence of influence of the program on children. A comparison of the profiles of ratings on Self-Regard with similar profiles drawn at the conclusion of the parent meetings indicated a high percentage of increase in children's Self-Regard at posttest. In addition, data on 2 scales of Self-Regard (Purposeful Learning Skills, and Dealing with Frustrations) were compared for experimental and control groups of children with mixed results. Overall results of the evaluation of the effectiveness of the program indicate that Realistic Parenting Skills was a successful adult education program for parents. (CM)
