Thanks Tina - 

I wasn't familiar with the 5-Factor or Hexaco models.   

Do you know if there are tests or questionnaires to determine where one would fall on these scales?

FIVE-FACTOR MODEL:

 "The Five Factor model breaks personality down into five factors (each of which are composed of six subtraits or facets) that are seen as the "primary colors" from which each unique personality is created.

The first letters of what are known as the "Big Five" factors form the mnemonic "OCEAN": 

* Openness to Experience (creative versus conventional); 

* Conscientiousness (disciplined versus disorganized);

 * Extraversion (outgoing versus withdrawn); 

 * Agreeableness (gentle versus harsh); and,

 * Neuroticism (anxious versus calm).

The first two chapters of the book provide a brief introduction to the Five Factor model and explain how Ashton and Lee discovered the missing sixth factor--the "H Factor"--thanks to some powerful computing power and data obtained from non-English speaking countries. 

HEXACO:

Chapter 3 describes a model that Ashton and Lee have created that they have named the HEXACO personality model. 

The HEXACO model is complementary to the Five Factor model. 

It retains the Extraversion, Agreeableness, Conscientiousness, and Openness to Experience factors of the Five Factor model. 

The major changes are that it adds the Honesty/Humility factor and replaces the "Neuroticism" factor with an "Emotionality" factor. 

In the HEXACO model "anger" related traits are located under the low pole of Agreeableness and not under Neuorticism as in the Five Factor model. (In the HEXACO the "X" stands for "eXtraversion" )."
