The methodology of L.A. Yovayshi was created by a well-known Lithuanian psychologist and deserved very much popularity, due to its accuracy and simplicity. The online questionnaire helps to identify the propensity to professional actions and determine the scope of activities most suitable for hobbies and skills. This technique of Yovayshi demonstrates to the participant various types of the profession according to psychological criteria and its relativity to each of the types.
The big five personality traits are the best accepted and most commonly used model of personality in academic psychology. The big five come from the statistical study of responses to personality items. Using a technique called factor analysis researchers can look at the responses of people to hundreds of personality items and ask the question "what is the best was to summarize an individual?". This has been done with many samples from all over the world and the general result is that, while there seem to be unlimited personality variables, five stand out from the pack in terms of explaining a lot of a persons answers to questions about their personality: extraversion, neuroticism, agreeableness, conscientiousness and openness to experience. There are many different measures of the big five personality traits. This test uses the Big-Five Factor Markers from the International Personality Item Pool, developed by Goldberg (1992).
