History and development[ edit ] Cattell physical sciences background[ edit ] The 16PF Questionnaire was created from a fairly unusual perspective among personality tests. Most personality tests are developed to measure just the pre-conceived traits that are of interest to a particular theorist or researcher. The main author of the 16PF, Raymond B. Cattellhad a strong background in the physical sciences, especially chemistry and physics, at a time when the basic elements of the physical world were being discovered, placed in the periodic table, and used as the basis for understanding the fundamental nature of the physical world and for further inquiry.

He called these 16 factors "source traits" because he believed that they provide the underlying source for the surface behaviors that are thought of as personality. Although some of Cattell's views proved controversial, particularly his advocacy of eugenicshis contributions to the scientific development of work on understanding human personality is undeniable.

The family moved to the seaside town of Torquay, in South Devonshire, when Cattell was 6 years old. There he spent his early childhood happily with his brothers and friends, and developed a lifelong love for the ocean and sailing.

When a local house was converted into a hospital, Cattell observed the wounded as they were brought from the battlefields.

This experience turned him into an unusually serious boy. Cattell won a scholarship to Torquay Boy's Grammar School where he excelled. Inhe was awarded a county scholarship to University College, London, where he earned a bachelor of science degree with first class honors in chemistry in Influenced by the work of Cyril BurtCharles Spearman who was developing factor analysisand Ronald Fisher who was developing analysis of variancewhom he had met during his chemistry studies, he turned his studies principally to psychology.

He entered the doctoral program in His dissertation topic was "The Subjective Character of Cognition and Presensational Development of Perception," and he received his doctorate in Also from the University of London, he earned a master's degree in education in and an honorary doctor of science degree in From toCattell taught at Exeter University and served as an advisory psychologist at Dartington Hall, a progressive school that received considerable attention in the s.

He accepted the offer, expecting to stay in the United States no more than two years. But inhe won an appointment to the G. Stanley Hall professorship in genetic psychology at Clark University.

He moved from there to a lectureship at Harvard inwhere he remained untilwhen he was appointed to a newly created research professorship in psychology at the University of Illinois and remained in that post until The next year, he moved to Honolulu, where he was appointed to adjunct professorships at the University of Hawaii and the Hawaii School of Professional Psychology.

In Hawaii he married Heather Birkett, a clinical psychologist who conducted research using Cattell's 16PF questionnaire, with whom he enjoyed the remainder of his life. He continued to publish more than four articles per year and two books per decade through the s and s, and remained active in writing even as he became sick with colon cancer, prostate cancer, and heart disease in the s.

He died of congestive heart failure in his sleep at his home in Honolulu on February 2, Work The personality theory that emerged from Cattell's empirical work provided a basis for describing the uniqueness of individuals.

It has been classified as "trait theory" though it deals with much more than merely the enduring characteristics whereby one person can be distinguished from another; it is also an account of states and systematic changes in behavior brought about through motivation and learning.

It provides a description of short-term and lifelong changes in behavior associated with neurophysiological, genetic, familial, social, and cultural factors. It is thus a comprehensive theory of human personality.

Cattell differentiated "source traits" from "surface traits. Source traits are those more basic traits that underlie the surface traits. Shyness, being quiet, and disliking crowds might all be surface traits related to the more basic source trait of introversiona tendency to withdraw from excessive stimulation.

Using factor analysis, a statistical technique that looks for groupings and commonalities in numerical data, Cattell discovered 16 source traits, and although in he determined that there might be some other seven source traits to make a total of 23, he developed his assessment questionnaire, The Sixteen Personality Factor Questionnaire, or 16PF, based on those 16 source traits.

They are seen as trait dimensions or continua, in which there are two opposite traits at each end with many possible degrees of the traits possible along the dimension. The Sixteen Personality Factor Questionnaire Cattell's The Sixteen Personality Factor Questionnaire grew out of the research on self-report data that he directed over a period of more than thirty years.

This well-respected and widely used personality test is based on the hypothesis that there is invariance across the media of observation, which means that some of the same important features of personality are seen, and can been measured, in different kinds of data—namely, behavior ratings and objective tests as well as self-reports.

Cattell's research, on which he developed the Sixteen Personality Factor Questionnaire, proceeded as follows: Establishing, by factor analytic means, independent dimensions of personality within behavior-rating data; Writing self-report items to represent these dimensions; Factoring to determine factors among the responses to these items.

Several forms of the 16PF have been produced—some for different language and culture groups, and some for poor readers.The Sixteen Personality Factor Questionnaire (16PF) is a self-report personality test developed over several decades of empirical research by Raymond B.
