Merkezileşme Ölçeği’nin Geçerlik ve Güvenirlik Çalışması

Abstract

The aim of the present study is to adapt Centralization Scale, which was developed by Aiken & Hage (1966) and Hage & Aiken (1967), and to test the validity and reliability of the scale. The study was carried out in three stages. In the first stage, translation studies, in the second stage validity analysis and in the third stage reliability analysis were performed. The method proposed by Brislin (1970) for adapting the scale to Turkish was used, and the data obtained as a result of the application of the scale to a sample consisting of 316 people (200 people for exploratory factor analysis and 116 people for confirmatory factor analysis) were used for expert opinion in the control of the scope and logical validity and in the analyzes conducted within the framework of the control of construct validity and reliability. SPSS and AMOS software and R programming language were used for analysis. As a result of the study; we revealed that Turkish version of the scale was formed in three-factors and factor loadings of sub-factors were collected between 0.871-0.846, 0.851-0.816 and 0.861-0.729 values, goodness of fit indices are conformed with the recommended values in the literature, Cronbach’s alpha coefficient value is 0.806, and other statistical values for reliability are conformed with previous studies. In this context, we revealed that Centralization Scale developed by Aiken & Hage (1966) and Hage & Aiken (1967) can be used conveniently in the field of social sciences in Turkey without any change in the factor structure and items. However, it is considered that it would be appropriate to check the suitability of the scale with the sample data via confirmatory factor analysis.
