Personality traits/Cattell/De Raad: Cattell’s original set of 35 trait variables was the result of a process of condensing a list of 171 trait descriptive items considered by Cattell (1943)(1) to summarize the complete ‘personality sphere’. That condensation took place on the basis of correlations of ratings from 100 subjects. The reduction to thirty-five variables was, in Cattell’s (1945(2), p. 70) words, ‘a matter of unhappy necessity’. Cattell (1950)(3) distinguished trait-elements (single trait words), surface traits (traits tending to cluster together in a person), and source traits (trait-factors), essentially forming a hierarchy of traits. The concept of hierarchy was extended in Cattell’s emphasis on the distinction between primary factors and higher order factors.

Personality Traits/Data/Cattell: [Cattell] proposed that the description and measurement of personality constructs should be undertaken via three basic media of observation (three different types of data). Firstly, L-data refers to information that is collected about individuals in real Life situations, either by recording a person’s actual behaviour, or obtaining an observer’s ratings of a given individual’s behaviour. Secondly, Q-data provides measurements of humans’ self-assessments of their own behaviour via self-report Questionnaires. T-data is obtained from objective Tests designed to measure actual behaviour (…).
Study Design/Cattell: Cattell (…) using the (1936) dictionary-based compilation [by Allport and Odbert] as a starting point for his empirical taxonomic personality research programme (…) proceeded by first reducing the list by grouping all synonymous terms together and then designating each synonym group under a key term. With the assistance of a literature student, Cattell spent several months parsing the list to a more manageable number of 171 synonym terms, beginning without any preconceived idea as to the number of separate categories needed. The next step was to organize most of the trait synonyms into a bipolar format by including opposites whenever possible.
Cattell then recruited a sample of 100 individuals, specifically selected to be as representative as possible of the general adult population. Members of the group were rated by a close acquaintance on each of the 171 trait terms. The raters estimated whether a person was high or low on each of the respective trait terms. Research assistants then calculated all 14,535 separate tetrachoric correlation coefficients between all of the 171 trait terms. Cattell employed the statistical technique of cluster analysis to create a list of 67 fundamental clusters representing surface traits of the normal personality sphere. He then reduced these cluster-based trait terms to a more practical number of 35 bipolar dimensions (…).
Findings/Cattell: Cattell (1944(1), 1946(2), 1973(3)) concluded that there were at least 12–16 primary source traits underlying the normal human personality sphere alone (subsequently, Cattell also identified an additional 12 abnormal personality trait factors measured in the Clinical Analysis Questionnaire or CAQ (…) giving at least 28 primary personality trait dimensions [Cattell, 1973, p. 127])(3). At the second-stratum level in the normal personality sphere, Cattell reported 5–8 broad factors (Cattell & Nichols, 1972(4); Cattell, 1973(3); Gillis & Cattell, 1979(5); cf. Boyle & Robertson, 1989(6); Gillis & Lee, 1978(7); Krug & Johns, 1986(8)).
Re-analysis of Cattell’s (1948)(9) data using modern factor analytic methods together with oblique simple-structure rotation supports Cattell’s pioneering research findings of 11–16 primary trait dimensions (e.g., Cattell & Krug, 1986(10); Chernyshenko et al., 2001(11); (…); McKenzie et al., 1997(12); (…).
