Development of reasoning styles scale

Abstract

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 (? = .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, ?2/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. © 2019 by authors, all rights reserved.
