The aim of this study was to create a Polish adaptation of the Multidimensional Attitudes Scale toward Persons with Disabilities (MAS) by performing a statistical psychometric analysis in a sample of Polish students. The study included 540 person (82.0% of students and 18.0% of workers), whose attitudes towards the disabled were measured with the Polish version of the MAS (MAS-PL). Mean age of respondents was 24.72 years (SD = 5.7), with a significant majority of women (n = 455, 84.3%). Data was collected during university classes and via an online survey. Factor analysis yielded a three-factor structure of the MAS-PL, including affective, cognitive, and behavioural domains, which explained almost 45% of the total variance. Further factor-based solutions increased this percentage only slightly (0.8). The Polish version of the MAS scale (MAS-PL) has been developed and presented as a reliable instrument for studying the attitudes of Poles towards people with disabilities. The scale can be used as a preliminary assessment tool when creating educational programmes, including those for training and social Policy, as well as assessing the effectiveness of programmes. Studies with the use of the MAS-PL will allow comparisons of research findings conducted with the use of MAS scales in other English-speaking (original/English MAS) or Spanish-speaking (Spanish MAS) populations and German (G-MAS), Korean (MAS-K), Serbian (Serbian MAS), Turkish (Turkish MAS) and French populations (French MAS autism).
