Validity and Reliability of the DeMoulin Self-Concept Developmental Scale for the 36-72 Month Old Children

Abstract

The aim of this study is to investigate the reliability and validity of the DeMoulin Self-Concept Developmental Scale for 36-72 month old children. In addition, it has been attempted to examine the effects of age and gender variables on the self-concept of children. The study is in survey method. The sample consists of 810 children who attend preschools in Istanbul, Turkey. Data collection tools used in the research are; the Demographic Form, the DeMoulin Self-Concept Developmental Scale for Children, the Social Competence and Behavior Evaluation Scale-30 and the Emotion Regulation Scale. The results of the item discrimination and criteria validity analyses support the validity of the scale. It could be said that the founded Cronbach’s Alpha value of the total scale and subscales and the results of the split half method and test-retest method analyses indicate that the scale is a reliable measurement tool. In addition, it has been found that the age variable affected the self-concept scores, but the gender variable had no effect on it. The research findings are discussed within the framework of the related literature.
