The 16PF Personality Questionnaire
The Sixteen Personality Factor Questionnaire (16PF) is a multiple-choice, comprehensive measure of normal range personality found to be effective in a variety of settings where an in-depth assessment of the whole person is needed. Developed over several decades, Raymond Cattell began to work on it in the 1920s when he shifted from the physical sciences to psychology and was shocked at the lack of empirical research available to enquire into the psychological nature of human beings. He wanted to develop a psychological test based on a list generated by Gordon Allport and H.S. Odbert, who had methodically gone through two comprehensive dictionaries to come up with around 18,000 words to describe personality. »
