What is tridimensional personality questionnaire?

Tridimensional Personality Questionnaire (TPQ) is a multidimensional personality assessment tool that measures the three dimensions of temperament: Novelty Seeking (NS), Harm Avoidance (HA), and Reward Dependence (RD). It was developed by the Finnish neuroscientist Jukka A. P. Saatela and American psychiatrist Robert R. Cloninger in the late 1980s.

The TPQ has 100 true/false questions that assess the traits and tendencies associated with each dimension. Novelty Seeking refers to an individual's tendency to seek out new experiences and take risks. Harm Avoidance measures the degree to which an individual is cautious and avoids danger and negative emotions. Reward Dependence evaluates how much an individual seeks rewards and positive social reinforcement.

The TPQ has been used in research to examine the association between personality traits and various mental disorders, including depression, anxiety, and substance abuse. It has also been applied in clinical settings to aid in diagnosis and treatment planning.

Overall, the TPQ is widely used and respected as a validated and reliable measure of personality dimensions.
