Three factors are measured in the children's scale: thrill and adventure seeking, drug and alcohol attitudes, and social disinhibition. Children aged 7 through 12 years were used to measure the reliability and validity of the scale. The scale was later changed to appropriately included items regarding substance use and sexual activity. [10]
In psychology, the Eysenck Personality Questionnaire (EPQ) is a questionnaire to assess the personality traits of a person. It was devised by psychologists Hans Jürgen Eysenck and Sybil B. G. Eysenck. [1] Hans Eysenck's theory is based primarily on physiology and genetics. Although he was a behaviorist who considered learned habits of great ...
Each behavioral and environmental factor coincides with the child and so forth resulting in a continuous battle on all three levels. [ citation needed ] Reciprocal determinism is the idea that behavior is controlled or determined by the individual, through cognitive processes, and by the environment, through external social stimulus events.
Eysenck suggests that different personality traits are caused by the properties of the brain, which themselves are the result of genetic factors. [17] In particular, the three-factor model identifies the reticular system and the limbic system in the brain as key components that mediate cortical arousal and emotional responses respectively.
Within Eysenck's "Big Three" model of personality, impulsive sensation seeking is most strongly related to psychoticism and within the Big Five personality traits it is primarily related to (low) conscientiousness. Sensation-seeking has a strong correlation with the novelty seeking scale of Cloninger's Temperament and Character Inventory. [1]
Psychoticism is conceptually similar to the constraint factor in Tellegen's three-factor model of personality. [1] Psychoticism may be divided into narrower traits such as impulsivity and sensation-seeking. These may in turn be further subdivided into even more specific traits.
Extensive personality research has been done that links positive emotional states to individual differences in risky behaviour. [1] The trait 'positive urgency', defined as the tendency to engage in risky behaviour under conditions of extreme positive affect, is predictive of substance or behavioural problems that lead to addiction.
