implementation of the five scales and 30 aspects of the Big Five model (see Five-Factor Personality Model), created in 1999 by Lewis Goldberg (the author of the term “Big 5”) within the framework of the IPIP project organized by him, as a freely available analogue of the commercial questionnaire NEO-PI-R. In 2014, Dr. John A. Johnson (PennState) posted an online version of both the full questionnaire and the abridged version of IPIP-NEO-120 he developed, and collected a large amount of data for normalization. In addition, the online Johnson test (as well as the translation presented here) provides a fairly detailed commentary on the scales and the results obtained.
