Raymond Cattell introduced his model of 16 personality factors in the 1940s. Although it took time to gain recognition, the 16PF questionnaire - originally developed for counseling and HR purposes - has since become one of the most widely used personality assessments in psychology.
This is a free online adaptation based on publicly available scales developed by L. Goldberg, D. Barenboym, A. Kapustina, and others. It is designed to assess the same 16 personality factors in a concise and accessible format.
The test measures core personality traits such as emotional stability, sociability, openness to change, self-discipline, and anxiety levels — offering a structured overview of how you think, interact, and respond to different situations.
Instructions
For each statement, choose the answer that best reflects how you typically think, feel, or behave — not how you would like to be seen. Try to answer every question and rely on your first instinct. Avoid selecting “I don’t know” unless absolutely necessary.
There are no right or wrong answers. Most people complete this version of the 16PF test in under 10 minutes.
