Twenty-five personality self-report items taken from the International Personality Item Pool

Description

The data set contains responses from 250 participants filling in twenty-five personality self-report items taken from the International Personality Item Pool (https://ipip.ori.org) as part of the Synthetic Aperture Personality Assessment (SAPA) web-based personality assessment (https://sapa-project.org) project. The 25 items are organized by five putative factors: Agreeableness (A1 to A5), Conscientiousness (C1 to C5), Extraversion (E1 to E5), Neuroticism (N1 to N5), and Openness (N1 to N5). The items were short phrases that the respondent should answer by indicating how accurately the statement describes their typical behaviour or attitude. Responses were collected using a 6-point scale: 1 - Very inaccurate, 2 - Moderately inaccurate, 3 - Slightly inaccurate, 4 - Slightly accurate, 5 - Moderately accurate, 6 - Very accurate.
