This personality test will provide an overview of your personality according to the Five Factor Model. The Five Factor Model is a scientific personality model that is widely used as the theoretical underpinnings for research in a broad range of disciplines. This model is generally considered more accurate and comprehensive than alternative personality tests, such as MBTI, PEN, Belbin, DSM, or DISC tests, but the Big Five can also seem more technical at first glance. The Five Factor Model is based on trait theory and measures 30 personalities all in all, divided into five main dimensions, namely the so-called Big Five.

The Big Five, or Five Factor Model (FFM), is the gold standard in social science, and is at the forefront of scientific personality testing. There is strong scientific evidence that the Big Five is solid, valid, and reliable. The Five Factor Model is a research-based model of personality based on statistical inference; the five top level traits of openness, conscientiousness, extroversion, agreeableness, and neuroticism are comprised of a total of 30 subscale personality traits, which are divided into these five main dimensions.

Although all are designed to measure the Big Five traits, the IDR-CBF-30 should not be confused with the IPIP-NEO or the NEO PI-R™, as authored by Paul T. Costa, Jr. and Robert R. McCrae. However, all are personality tests (or inventories) for measuring traits within the Big Five or Five Factor Model (FFM) system of personality. The NEO PI-R™ is the property of Psychological Assessment Resources. The specific expression of the IDR-CBF-30© is the property of IDR Labs International.
