The purpose of this study was to translate and adapt the ATIPDPE-R attitudinal scale (Kudlacek, Valkova, Sherrill, Myers, & French, 2002), an instrument based on the theory of planned behavior (TPB) of Ajzen (2000) and to examine the structure of the translated Slovene version, ATIPDPE-R-SL. The participants were 175 prospective educators: 124 females (average age = 22.47) and 51 males (average age = 23.78) enrolled in physical and general education teacher preparation programs in Slovenia. The conclusions are based on the ATIPDPE-RSL analysis attitudinal scale of measurements of three psychological properties (components) of behavioural beliefs (attitudes toward inclusion). Three components, which came from principal component analysis, explain more than 55 % of the variance. The components were the same as in original the study: a) positive outcomes for students, b) negative outcome for teachers, and c) negative outcome for students.
