Περίληψη:
Likert’s contribution has been definitive in the development of attitude measurement scales. The measurement of attitudes constituted and still constitutes, an area of disagreement in the scientific circle. The method proposed by Likert in 1932 has been a milestone. The specific method in the measurement of attitudes has helped override difficulties that had been observed in the Thurstone scale. As a result, the Likert scale constitutes today one of the most widespread and widely used scales. Given that their theory is correctly applied, Likert scales achieve in impressing respondents’ views with regards to significant social issues as well as in investigating the individual’s psychological reactions towards various social stimuli. Their application is wide, and they constitute an important tool in the field of psychosocial sciences.The object of the present dissertation is the presentation of the various stages that are required for the creation and evaluation of Likert scales and more specifically, the manner in which reliability and validity are estimated. For this purpose, a xenophobia scale has been used which has been included in the questionnaire used in a research conducted by the National Centre for Social Research and was published in the book “Macedonia and the Balkans, Xenophobia and Development”.What the dissertation demonstrated, was that the scale’s reliability is estimated with the use of reliability analysis and alpha coefficient. Of all the types of validity, in practice, the one that can be easily approached is construct validity for which the conduct of factor analysis is required.
