The aim of this study is to develop the reasoning style scale. The study was conducted with 300 undergraduates from different departments at Ondokuz Mayıs University during the 2016-2017 academic year. Factor analysis was used to validate the structure of the scale. The KMO coefficient (783) and the Barlett test (p <.05) were found to be significant for the Kaiser-Meyer Olkin (KMO) and Barlett tests. The Cronbach’s Alpha correlation coefficient used for the reliability coefficient was found for all of the scale (α = .784). As a result of the analyzes, “Reasoning Styles Scale” was developed as 5 likert and 4 sub-dimensions, and was found to be valid and reliable. The results of the exploratory factor analysis were applied to a sample of 109 students. Thus, χ2/sd was found to be 1,377; CFI value was found to be,943; GFI value was found to be, 906; IFI value was found to be, 945; TLI value was found to be,930; RMSEA was found to be,059; RMR value was found to be,061. As a result, a 12-item four-dimensional scale was obtained.
