About the Big Five Inventory

The Big Five Inventory (BFI) is a self-report inventory designed to measure the Big Five dimensions. The Big Five Inventory is a short multidimensional personality inventory, containing only 44 items. It consists of short phrases with relatively simple vocabulary. There is a shorter version that contains 11 items, but since the BFI is already short and only takes about five minutes to complete, it is recommended to take the full BFI.

This test should not be confused with the Big Five Model; they are two different tests.


The BFI Dimensions

The dimensions the BFI measure are:

  • Extraversion vs. Introversion
  • Agreeableness vs. Antagonism
  • Conscientiousness vs. Emotional Stability
  • Openness vs. Closed-Mindedness to Experience

The items found on the test use a scale from 1-5 ranging from Disagree Strongly to Agree Strongly.

The BFI may also be used during an interview. If that is the case, the interviewer will ask the statements in the form of a question. They will phrase the questions by asking you to consider whether you agree or disagree with each item — you may only choose one way. You will then have to rate how much you agree or disagree with the statement.
