Not done Sir, but doing.

Plenty is doing.

"The six [Promax factors] for the [379] adults [who took a 105-item version of Cattell's 16PF Test in the course of a survey in Virginia into cardiovascular risk factors] are: Extraversion [e.g. 'talk too much', 'enjoy inviting guests' vs shyness]; Neuroticism [e.g. 'bothered by others' opinions', 'sometimes feel like crying', prefer dancing to wrestling, 'highly strung', 'have strong emotional moods']; Psychoticism [e.g. 'unco-operative', 'impatient', 'always speak my mind', 'like to have things my way', inconsiderate, 'not annoyed by off-colour jokes / tardiness']; (?= Independence) Conservatism [e.g. prefer bowls to chess, jokes to politics, attending class to reading, Columbus to Shakespeare, prose to poetry, practical to contemplative friends]; (?= Tough-mindedness) IQ [e.g. continuing a number series]; and Superego Strength [e.g. 'interested in hearing details of accidents', 'think planning ahead is worth it', 'bothered by hearing things against my own beliefs', 'use spare time to do odd jobs (vs chatting)'].... Similar to previous investigators, we found no evidence for a factor structure similar to Cattell's (primaries).... Our six factors for the adults are quite similar to six of the seven found by Kline and Barrett (1983, Advances in Behav. Res. & Therapy 5). They are more stable than Cattell's primary traits, and do not have such high inter- factor stability coefficients."
