In attempting to uncover the major dimensions of personality, Mr.R. B. Cattell wanted to empirically determine and measure the essence of personality. Based on that, Cattell concluded that the human personality has 16 basic dimensions. The product of his marathon task was the sixteen personality factor questionnaire, better known as 16 PF, which was subsequently revised following continued factor analysis. Consistent with the factor analytic strategy, items that correlated highly with each of the 16 major factors, or source traits, were included, and those with relatively low correlations were excluded. In the standardization of the 16 PF it is fitness of things to find separate norms provided for men and women. 16 PF facilitates generating of personality profile, which needs to be carefully interpreted.
