the 'big five' factors personality model

N.B. The pink color in the tables is used for the Big Five terminology recommended by Paul Sinclair. Aside from this, color is used (hopefully) to improve presentation only, and does not relate to other personality models on this webpage.

the big five model - five 'bipolar' scales

The bold names in the left column are the recommended names (by Paul Sinclair) for these factors. Other names are used for each of the factors, which might equate to names in the left or right columns. See the OCEAN names below.

These scales are commonly alternatively represented by the OCEAN acronym and descriptions:

While some psychologists refer to the OCEAN terminology it's not particularly recommended for use where people are likely to be sensitive to the words, notably 'neuroticism'. Other words in the OCEAN scale can also be perceived as judgmental or stigmatized. And while 'Conscientiousness' is technically accurate, using this word tends to influence decision-makers (notably users of psychometric testing systems) towards the characteristic and those displaying it, not least because the other end of the scale would logically be called 'Unconscientious'; better instead to refer to the scale of 'Detail-conscious - Unstructured', which carries no sense of good or bad.

It is generally more helpful to use the Big Five terms as detailed in the grid, which tend to present the scales as 'one or the other' rather than 'good or bad'.

For the sake of reference however, here is the correlation between the OCEAN Big Five factor names and the more user-friendly names. See above for the precise description correlations.

You will find other variations of how people refer to the Big Five Factors.

For example The Big Five according to McCrae & Costa (1987) is typically shown as:

The following tables show the typical behaviors within this model.

Psychologists and psychometrics practitioners use the term 'Factor' to describe each of these five 'large traits' or scales.

In turn, each of the Big Five Factors contains several behaviors, which are clustered under the five main Factor headings. 

Of course each main Factor can be further broken down into 'sub traits' or 'facets', for example, Extraversion could have sub-traits such as Sociable, Competitive, Energetic and Seeking Recognition.

Each factor is named according to the 'high scoring' end of each scale.

Low scores logically indicate behaviors at the opposite side of the scale.

High scores are not good or bad.

Low scores are not good or bad.

The majority of us actually tend to score close to the middle (the 'norm').

The higher a person scores for the behavioral elements shown within each of the five factors, the more (logically) they will exhibit these behaviors, and be less able to sustain the tendencies of the low scorer. And vice versa.

Again, there is no good or bad. It's simply a measure of what we are.

the big five factors including behavioral elements

Other commonly used factor names (notably OCEAN) for the Big Five Factors are shown in Green.

the combinations of factors define the personality - not single scales

When using this model, as with many other personality concepts, it is the combination of scores from all of the scales that shows us how people operate and identifies their underlying preferences.

Looking at a single scale in isolation tells us hardly anything, and can be very misleading.

For example:

Although a creative (non-conformist) has the intellectual ability to be creative, if their non-conformity is combined with introversion and low confidence, they may not express their creative thoughts and ideas. 

A creative (non-conformist) who is also extravert, confident and unstructured (low detail-conscious), will not only express their ideas but may also propose quite impractical suggestions.

usage of the big five factor model

The Big Five is a very useful model for assessing non-managerial staff, but it lacks some of the rigor required for assessing people in or destined for managerial and executive roles. The Big Five model gives us an accurate and fast way of assessing the main drivers of someone's personality. But the model by itself is not able to drill down into complex management capabilities or competencies. For this we must refer more to work-related behaviors rather than 'pure' personality.

Management performance depends more on the subtle use of discretionary elements of the job, which the Big Five will not measure. The Big Five is a 'broad brush' personality methodology. A different approach is required for management assessment, to gauge the 'components' of people's behavior and the detailed combinations of working style. The 'PRISM' model (PRISM is summarized separately here) and similar systems are more appropriate for measuring management style and potential than the Big Five.

Each of the Big Five factors consists of 'sub-traits', for example, 'Agreeable' (at the opposite end of the 'Tough-minded' scale) consists of sub-traits (behavioral elements) such as 'Tactful', 'Diplomatic', 'Team-centered', 'Submissive', 'Warm', 'Friendly', 'Tolerant' and 'Democratic'. In typical use of the Big Five model and tests, a person's score on the 'Agreeable' scale will be an average of how they match the sub-traits. Showing the detail and variance of the sub-traits scores would entail a vastly more complex and time-consuming analysis.

The strengths of the Big Five Factor model lie in its speed and ease of use and this makes it a very useful tool for gaining a rapid overview of a person's key drivers.

The Big Five Factor model has been very well validated, and while it has shown correlations with performance in jobs, studies indicate that the correlation with particular jobs does not exceed 0.30, which accounts for no more than 15% of the variables. There is a big difference between measuring job suitability, style, etc., and measuring personality per se.

The Big Five model is a modern, widely replicated and validated methodology for understanding, explaining and measuring personality.

Various Big Five tests have been developed. The first to be launched in the UK, and one of the most popular, is the RPQ (Rapid Personality Questionnaire), which is available from various suppliers.

Here is a free Big Five mini-test (5 mins max) on the excellent website of Professor George Boeree (pronounced boo-RAY). This test gives a very quick Big Five profile and is more for understanding the model thank for serious personality assessment, although as a quick simple guide it works well.

Bear in mind that the Big Five factor headings Professor Boeree's mini-test vary slightly compared to factor names mentioned above, and correlate as follows (precise correlations in bold). Aside from 'Stability' Boeree uses the OCEAN headings:

the big five - some notable combinations

The 'personality-based sub-types' in column one are broad generic profiles and do not relate to any particular model's definitions. Be careful not to read too much into these single-word descriptions - they provide a rough guide, not a detailed scientific correlation.

'the big five' correlations with other personality models

Here are correlations between the Big Five factors and respectively the models of 16PF, OPQ and the Belbin 'team role' types.

Below first are the Big Five correlations with Cattell's 16PF model. Understanding these correlations is aided by knowing the 16PF scale definitions. As ever, single word descriptions are open to different interpretations, hence inclusion of the 16PF letter codes. An explanation of the 16PF model will appear on this page in due course.

The word 'negatively' below means that the correlation is with the opposite end of the Big Five scale concerned, for example, below, the 16PF description 'Shrewd' correlates to the opposite of the Big Five 'Extraversion', ie., 'Introversion'

big five and 16pf

the big five and opq (occupational personality questionnaire)

Below are the Big Five correlations with the OPQ model (Occupational Personality Questionnaire). Understanding these correlations is aided by knowing the OPQ scale definitions. As ever, single word descriptions are open to different interpretations, hence inclusion of the OPQ letter codes. Again, an explanation of the OPQ model will appear on this page in due course.

And again, the word 'negatively' signifies that the correlation is to the opposite end of the Big Five factor concerned, eg., OPQ description 'Modest' correlates to the opposite of the Big Five 'Extraversion', ie., 'Introversion'.

the big five and belbin 'team role' types

Below are the Big Five correlations with the Belbin team role types. Given the overlap of Big Five factors across the Belbin team role types, the correlations are shown between the Belbin types and the corresponding dominant Big Five factors. See the Belbin section above.
