The paper presents the results of approbation of the Russian-language version of the Job Anxiety Scale (JAS) by B. Mushalla and M. Linden, based on a differentiated clinical approach to anxiety states during work. The 70-item scale was translated into Russian and tested in a sample of 410 subjects, who were professionals in various fields. The exploratory factor analysis procedure identified a five-factor structure that was different from the original one. The factors were named as follows: 1) Discomfort, tension, and anxiety at work with the conviction of its harmfulness; 2) Social anxiety and avoidant behavior in the workplace; 3) Experiencing injustice and exploitation in the workplace; 4) Anxiety for the preservation of the workplace and the future; 5) Cognitions about one's inefficiency. High reliability of the Russian version of JAS has been established. The Cronbach's α coefficient for the entire scale was 0.973; the Gutmann split-half coefficient was 0.945. There were multiple correlations between the JAS scores and the symptoms of mental disorders assessed by the SCL-90-R, which can be considered as evidence of the external validity of the scale. © 2020 Moscow State University of Psychology and Education.
