Abstract

The study tested the hypothesis that impulsivity is associated with multiple substance dependence. Fifty-four subjects who had participated in a study of personality and substance abuse had also completed Barratt's [1985; Advances in personality assessment (Vol. 5). Hillside, NJ: Lawrence Erlbaum] impulsivity scale. They had completed personality questionnaires including Eysenck's EPQ, and received DSM-III-R axis I diagnoses by structured interview. Multiply dependent subjects had higher impulsivity and EPQ psychoticism scores than those dependent on a single substance. In addition, impulsivity and EPQ psychoticism scores were highly correlated with the number of substances subjects had been dependent on. The results support the idea that multiple substance dependence is associated with impulsivity, and that impulsivity is a feature of Eysenck's psychoticism dimension.
