What Is the BFI-44?
The Big Five Inventory (BFI-44) measures five broad personality dimensions that emerge consistently across cultures. Unlike pop-psychology tests, the Big Five is one of the most researched models in personality psychology.
Extraversion (E) — Outgoing and energetic vs reserved and solitary.
Agreeableness (A) — Compassionate and cooperative vs suspicious and competitive.
Conscientiousness (C) — Organized and disciplined vs careless and impulsive.
Neuroticism (N) — Anxious and moody vs calm and emotionally stable.
Openness (O) — Curious and imaginative vs conventional and cautious.
The Five Domains
The BFI-44 uses 44 items rated on a 5-point scale (disagree strongly to agree strongly). Each domain score is computed from 8-10 items. Most people take about 10 minutes.
