This study is aimed at developing a three-dimensionally centered art therapy program and studying its effect on the self-concept and social abilities of children from single-parent families. Common objects in art therapy such as a house, people, trees and bridges were selected as symbolic main themes. The three-dimensional art therapy program is designed to motivate growth and openness in children while creating objects that help children discover their potential and develop insights about themselves. Children were divided into an experimental group of 8 children and a control group of 8 children. The three-dimensionally centered art therapy program was conducted on the experimental group for 90minutes twice a week, 20 times in total, from July to October 2010. The results of this research are as follows: First of all, the three-dimensionally centered art therapy program plays a positive role in improving the self-concept of children from single-parent families. Children had meaningfully higher self-concepts in all of its sub-sectors; their physical, family, social, emotional and academic sectors. Secondly, the result shows that the three-dimensionally centered art therapy program plays a positive role in improving the social abilities of children from single-parent families. It was found that the three-dimensionally centered art therapy program has positive effects on all four sociality abilities: diligence, cooperation, people skills and self-reliability. As a conclusion, this study proves that the three-dimensionally centered art therapy program has apositive effect on improving self-concept and social abilities of children from single-parent families.
