TABLE 3.

Reliability estimates (with confidence intervals) and intercorrelations for scores from BFI-2 domains (Study 1 and 2).

Domain/Facet	α [95% CI]	M	SD	E	A	C	N	O
Extraversion	0.82 [0.80, 0.84]/0.85 [0.83, 0.87]	3.80/3.57	0.58/0.66		0.11/0.18	0.18/0.18	–0.25/–0.26	0.31/0.30
Agreeableness	0.79 [0.76, 0.81]/0.81 [0.78, 0.83]	4.00/3.76	0.51/0.58	0.11/0.18		0.34/0.29	–0.30/–0.25	0.14/0.10
Conscientiousness	0.83 [0.80, 0.85]/0.85 [0.83, 0.87]	4.22/3.84	0.53/0.64	0.18/0.18	0.34/0.28		–0.21/–0.18	0.01/0.10
Negative Emotionality	0.86 [0.84, 0.87]/0.90 [0.89, 0.92]	2.25/2.65	0.67/0.86	–0.25/–0.26	–0.30/–0.25	–0.21/–0.18		–0.08/–0.10
Open-mindedness	0.81 [0.79, 0.84]/0.83 [0.80, 0.85]	3.74/3.51	0.64/0.71	0.31/0.30	0.14/0.10	0.01/0.10	–0.08/–0.10

E, Extraversion; A, Agreeableness; C, Conscientiousness; N, Negative Emotionality; O, Open-Mindedness. The figures before and after the forward slash are from Study 1 and 2, respectively. N = 599–601 for Study 1, and N = 409 for Study 2. Absolute correlations 0.11 or stronger (for Study 1) and 0.18 or stronger (for Study 2) are significant at p < 0.01. α [95% CI] = Cronbach’s alpha with 95% confidence intervals estimated with the two-way mixed consistency approach for estimating ICC in SPSS (Bravo and Potvin, 1991; Baumgartner and Chung, 2001).
