The most recent form of Cattell's 16 Personality Factor approach declares that the 16 personality traits are results of five major personality factors. This is quite similar to the five-factor approach in that the global properties of personality are restricted to five characteristics.ersonality traits and scales used to measure traits are numerous and commonality amongst the traits and scales is often difficult to obtain. To curb the confusion, many personality psychologists have attempted to develop a common taxonomy.
