Second Stratum Personality Factors Defined In The Questionnaire Realm By The 16 P.F.

To determine the factors in the correlations between the 16 P.F. scales on the basis of a heterogeneous sample, a correlation matrix ( N = 1,652) was determined by combining data from several samples. Eight factors were ex- tracted on the basis of mathematical and statistical considerations and rotated to simple structure. The major f a c b r s were Anxiety, Exvia vs. Invia (extraversion vs. intro- version but with limited social orientation), Cool Rationality vs. Pathemia (affectivity), and Independence vs. Subduedness. Smaller factors included Cultured Tact vs. Spontaneity, and Untamedness vs. Sensitive Practicality. The present study suggests that several stable second order factors may possibly be established in addition to the usual ones of Anxiety and Exvia- Invia.
