The data regards the 'Big 5' Personality traits- agreeableness,
openness, extraversion, neuroticism, and conscientiousness. The items are
based on a 6 point response scale: 1 Very Inaccurate 2 Moderately
Inaccurate 3 Slightly Inaccurate 4 Slightly Accurate 5 Moderately Accurate
6 Very Accurate. This is the same as the
bfi data set in the
psych package, except with reverse coded items already reversed as
they would need to be for scoring purposes. More details can be found at
bfi help file.
