Relationship To Five Factor Models
In the Fourth and Fifth Editions of the 16PF, there were five global factors that seem to correspond fairly closely to the "Big five personality traits." The Big Five (BF) trait of Openness seems to be related to 16PF Openness/Tough-mindedness, The BF trait of Conscientiousness to the 16PF Self-Control, the BF Extraversion to the 16PF Extraversion, the BF Agreeableness/Dis-Agreeablenss to the 16PF Independence/Accommodation, and the BF Neuroticism to the 16PF Anxiety. In fact, the development of the Big-Five factors began by factor-analyzing the same original items as the 16PF. and in 1963, W.T. Norman replicated Cattell's work and suggested that five factors would be sufficient.
However, one big technical difference between Cattell's five Global Factors and popular five-factor models was Cattell's insistence on using oblique rotation in the factor analysis whereas Goldberg and Costa & McCrae used orthogonal rotation in their factor analysis. Oblique rotation allows the factors to correlate with each other, whereas orthogonal rotation restricts the factors from correlating with each other. Although personality traits are thought to be correlated, using orthogonal factor analysis makes the factors easier to understand and to work on statistically in research. This is one of the reasons the Big-Five traits have definitions that are different from the 16PF global factors. For example, as seen in the table below, in Cattell's model the primary personality trait of Dominance (Factor E) is strongly located in the Independence/Accommodation global factor which represents a quality of fearless, original thinking and forceful, independent actions. However, other popular big five models consider Dominance as a facet of several Big-Five traits, including Extraversion, Dis-Agreeableness, and Conscientiousness. Thus Dominance is spread across a range of Big-Five factors with little influence on any one (Cattell & Mead, 2008). Below is a table that shows how the 16 primary factors are related to the five global factors of the 16 Personality Factor theory. Compare with the Hierarchical Structure of the Big Five. Also, note that factor B is considered separate from the other factors because it is not a part of the hierarchical structure of personality in the same way as the other factors.

“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
