Substance abuse, comorbidity, and sensation seeking: Gender differences

Two hundred sixty-two probands and 261 of their relatives with DSM-III-R diagnoses of drug and alcohol abuse and/or anxiety disorders completed the Zuckerman Sensation Seeking Scale. It was hypothesised that subjects with both substance abuse disorders and comorbid anxiety disorders would have lower sensation-seeking profiles than subjects with substance abuse alone. This was confirmed in women, with thrill- and adventure-seeking scores showing significant differences between pure substance abusers and those with a comorbid anxiety disorder, lending support to theories that substance abusers are a heterogeneous group. In men, there were fewer significant differences between diagnostic groups. If substance abusers are indeed a heterogeneous group, with some motivated by high sensation-seeking needs, a better understanding of these motivations can lead to more effective strategies of prevention and treatment, according to etiology.
