What BFI-2-S measures
The short BFI-2 measures Extraversion, Agreeableness, Conscientiousness, Negative Emotionality, and Open-Mindedness. Each domain samples three narrower facets, but two-item facet scores are too fragile for individual interpretation here.
How scoring works
Each domain contains six items: three worded toward the higher pole and three toward the lower pole. Lower-pole items are scored in the opposite direction behind the scenes, then the six values are averaged to 1–5. The interface does not reveal keys while answering.
