Big Five Inventory
The Big Five Inventory (BFI) is a valid and reliable psychodiagnostic instrument designed to measure five dimensions of human personality. It is relatively brief for a multidimensional personality inventory (44 items in total) and consists of short sentences with a relatively accessible vocabulary. Specifically, it measures the following dimensions of human personality:
- Neuroticism
- Agreeableness
- Extraversion
- Conscientiousness
- Openness
Length of completion
The entire questionnaire will take approximately 10 minutes to complete.
Individualized feedback for the respondent
After completing the questionnaire, the respondent will learn about themselves and how they stand on each personality dimension.
Keywords
Big Five, personality, extraversion, neuroticism, agreeableness, conscientiousness, openness
Scoring and interpretation
Extraversion: 1, 6R, 11, 16, 21R, 26, 31R, 36. Agreeableness: 2R, 7, 12R, 17, 22, 27R, 32, 37R, 42. Conscientiousness: 3, 8R, 13, 18R, 23R, 28, 33, 38, 43R. Neuroticism: 4, 9R, 14, 19, 24R, 29, 34R, 39. Openness: 5, 10, 15, 20, 25, 30, 35R, 40, 41R, 44. Before beginning the assessment, it is necessary to convert the scores for the reverse items (denoted by R after the item number) that measure the opposite poles of the traits. Summing the scores yields a total score for each dimension. A higher score indicates a higher trait measure.
Response Scale
The BFI method uses a Likert-type scale for responses, where the proband expresses their agreement on a five-point scale (1 = strongly disagree, 2 = rather disagree, 3 = neither agree nor disagree, 4 = rather agree, 5 = strongly agree).
