16PF

16PF stands for the 16 Personality Factors or 'source traits' that were identified by Raymond Cattell in the 1930s as being the main set of factors whereby a person can be classified. There are 16 Primary Factors, which have also been grouped into five global factors.

Unlike some other systems, the focus of the 16PF is to identify characteristics without immediate concern for how they are applied.

The Five Global Factors (16PF5)

This is a simplification from the above 16 factors, which are sometimes also called the 16PF5. Note that these are very closely related to the 'big five'. These are not a simple grouping of the 16PF - some of the sixteen appear in more than one of the five.

Global Factors	Low	High
Extraversion	Introverted, socially inhibited	Extraverted, social participant
Anxiety	Low anxiety, relaxed, imperturbable, well-adjusted	High anxiety, tense, perturbable, histrionic
Tough-Mindedness / Willpower	Receptive, open-minded, intuitive, emotionality, feeling	Tough-minded, resolute, non-empathetic, determined
Independence	Accommodating, agreeable, selfless, subdued	Independence, persuasive, wilful
Self-Control	Unrestrained, impulsive, uncontrolled	Self-controlled, inhibitory of impulses

So what?

Assess people either roughly using the above table as a guide or more fully using the standard questionnaire. The general principle is that these factors are pretty fixed, so you can then project them onto other situations.
