title: [Addiction and personality traits: sensation seeking, anhedonia, impulsivity].
abstract: This study presents the evaluation of three dimensional traits of personality (Sensation Seeking, Anhedonia, Impulsivity) among 65 patients admitted in a psychiatric ward, with or without addictive behaviors. Our objective is to establish that these personality traits are commun to all addictive behaviors and to test the hypothesis that high scores on the three scales are linked to a greater probability of presenting with addictive behaviors. The two most frequent types of addiction were alcoholism and drug abuse. The subjects presenting with one or several addictive behaviors had higher average scores on the three scales. Our results printed in the same direction for the subjects having shown an addictive behavior in their past history. The risk to present with an addictive behavior increased with the total scores of these self-report questionnaires. There was a significant relationship between 3 sub-dimensions on the Sensation Seeking Scale and addictive behavior. Each time sub-scores of boredom susceptibility, disinhibition and thrill and adventure rise by one, the risk to present with an addictive behavior is multiplied by 1.4 for the first two and by 1.3 for the third one. Subjects with high scores on the anhedonia and impulsivity scales respectively show a risk multiplied by 1.6 and 3.3 of developing an addictive behavior. These results of this transverse study confirm the link between addiction behavior and these three personality traits.
