The
Sixteen Personality Factor Questionnaire (
16PF), is a self-report
personality test developed over several decades of empirical research by
Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber. The 16PF provides a measure of normal
personality and can also be used by psychologists, and other
mental health professionals, as a clinical instrument to help diagnose
psychiatric disorders, as well as help with
prognosis and
therapy planning. The 16PF instrument provides clinicians with a normal-range measurement of
anxiety, adjustment, emotional stability and behavioral problems. It can also be used within other areas of
psychology, such as career and occupational selection.
