What is the Big Five Personality Inventory?

The Big Five Personality Inventory is a comprehensive personality assessment based on the Five-Factor Model (FFM), which measures five broad dimensions of personality that capture individual differences in thinking, feeling, and behaving.

Who developed it and when?

The Five-Factor Model emerged from decades of personality research, with significant contributions from Lewis Goldberg, Paul Costa, and Robert McCrae in the 1980s and 1990s. This assessment is based on the NEO-PI-R framework.

What type of assessment is it?

Self-report personality questionnaire using Likert-scale responses.

What does it assess?

• Openness to Experience: Creativity, curiosity, and openness to new ideas
• Conscientiousness: Organization, responsibility, and self-discipline
• Extraversion: Sociability, assertiveness, and positive emotions
• Agreeableness: Cooperation, trust, and empathy
• Neuroticism: Emotional instability, anxiety, and negative emotions

How many items and what format?

50 items (10 per domain), rated on a 5-point scale from "Strongly disagree" to "Strongly agree".

How is it scored?

Each of the five personality dimensions is scored separately, with some items reverse-scored. Higher scores indicate stronger presence of each trait.
