BFI2 Dataset

Description

BFI2 dataset (Hřebíčková et al., 2020) consists of responses of 1,733 respondents (1,003 females, 730 males) to Big Five Inventory 2 (BFI-2). It contains 60 ordinal items, vector of age, education, and vector of gender membership.

Usage

BFI2

Format

BFI2 is a data.frame consisting of 1,733 observations on 64 variables.

i1–i60

The BFI items, scored on Likert scale where 1 = Disagree strongly, 2 = Disagree a little, 3 = Neutral; no opinion, 4 = Agree a little, and 5 = Agree strongly. Some items were recoded so that all items are scored in the same direction, see Details.

Gender

Gender membership, 0 = females, 1 = males.

Age

Age in years.

Educ

Education, 1 = Basic school, 2 = Secondary technical school, 3 = Secondary general school, 4 = Other secondary school, 5 = Tertiary professional school, 6 = Bachelor degree, 7 = Masters degree, 8 = PhD

Details

The items prefixed with i are item scores. Items are indicators of 5 latent personality factors/dimensions/domains, which are further broken down into so-called facets. The 5 personality domains are: N = Negative Emotionality, E = Extraversion, O = Open-Mindedness, C = Consciousness and A = Agreeability. These are further broken down into so-called facets, as shown in the following table:

Domain	Facet	Item numbers
E	Sociability (scb)	1, 16, 31, 46
E	Assertiveness (asr)	6, 21, 36, 51
E	Energy Level (enl)	11, 26, 41, 56
A	Compassion (cmp)	2, 17, 32, 47
A	Respectfulness (rsp)	7, 22, 37, 52
A	Trust (trs)	12, 27, 42, 57
C	Organization (org)	3, 18, 33, 48
C	Productiveness (prd)	8, 23, 38, 53
C	Responsibility (rsp)	13, 28, 43, 58
N	Anxiety (anx)	4, 19, 34, 49
N	Depression (dep)	9, 24, 39, 54
N	Emotional Volatility (emt)	14, 29, 44, 59
O	Intellectual Curiosity (int)	10, 25, 40, 55
O	Aesthetic Sensitivity (aes)	5, 20, 35, 50
O	Creative Imagination (crt)	15, 30, 45, 60

In the original instrument, some items are inversely oriented, i.e., the higher score means the lower latent trait. This was the case of items number 3, 4, 5, 8, 9, 11, 12, 16, 17, 22, 23, 24, 25, 26, 28, 29, 30, 31, 36, 37, 42, 44, 45, 47, 48, 49, 50, 51, 55, and 58. These items have been recoded for you, i.e., displayed is value of ⁠6 - original score⁠.

In the sample code, alternative item names are provided. These item names can be used to decode the item domain, facet, item number, and whether it was recoded or not. For example, iCorg03r stands for recoded 3rd item (out of 60) from Consciousness domain and Organization facet.
