Psychometric evaluation of the Authenticity Scale on the sample of students in Serbia

Abstract

The aim of this study, conducted at two time points, was to evaluate the psychometric properties of the Serbian translation of the Authenticity Scale on the sample of students. The paper presents the results of testing the validity construct of the Authenticity Scale by confirmatory factor analysis at two time points, on the initial sample of 706 students and on the test-retest sample of 206 students within a 10-week interval. The model in which there are three separate, mutually related dimensions with the superordinate factor of authenticity best describes the scale structure. The test-retest sample was used to test the convergent validity of the Authenticity Scale by evaluating its relation to the measures of both positive and negative affect, self-esteem, psychological distress and psychological well-being and mental health index. The results showed that the Serbian translation of the Authenticity Scale represents a reliable and valid measure of authenticity.
