摘要：This study was conducted to provide a point of view about scaling methods using in psychology and social sciences and to determine the consistency between scaling values obtained by these two scaling methods. In this study, an attitude scale about BYM was used to collect data. Research was carried out on 2100 high school students and 84 experts. A series scaling procedure was conducted to obtain a scale value. In order to determine the relationship between scaling values obtained from two different scaling procedures, Spearman rho correlation coefficient was calculated. At the same time, in order to provide validity concerning the two different approaches, ANOVA and correlation analysis was conducted. The study revealed that there was a medium level (rs=0,43) relationship between scale values obtained from the different scaling approaches. When the number of items was taken as a criterion (K= 20) for developing a scale, 13 items were selected common to the final scale. Although there were differences between scale items selected for different scaling approaches, these two scaling procedures produced similar results with respect to validity.
