the third version of the personality questionnaire by Hans Jürgen Eysenck, it was published in 1963. It consists of two scales: extroversion-introversion and neuroticism, plus a scale for assessing the sincerity of answers. For a long time, this questionnaire confidently occupied one of the first places in terms of frequency of use among psychodiagnostic methods. Eysenck developed two versions of this test – A and B, which differ only in the text of the questions, which allows for repeated comparative studies.
