This study aims to examine reliability and validity analysis of the Balanced Differentiation and Integration Scale (İmamoğlu, 1998) on an adolescence sample and test the psychometric properties of the scale. The data was obtained from 1658 high school students from 16 high schools in four provinces in Istanbul that have the highest rates of immigration (Zeytinburnu, Gaziosmanpaşa, Büyükçekmece and Esenyurt Regions). The data was divided into two sets. In the first set, Explanatory Factor Analysis was conducted, and 6 factors were found, which is similar to Imamoğlu’s study. In the second data set, Confirmatory Factor Analysis was conducted, and it was found that the model is acceptable. This study is based on the data collected as a part of TÜBİTAK 1010 Project.
