Sensation Seeking and Cocaine Dependence in Adults With Reported Childhood ADHD

Abstract

Objective: To compare measures of sensation seeking in a clinical group of cocaine-dependent (CD) patients with and without a history of probable childhood ADHD and in non-cocaine-dependent (NCD) healthy volunteers. Method: Patients ( n = 75; 42 with and 33 without probable childhood ADHD) and comparisons ( n = 84) were assessed with the Diagnostic Interview for Genetic Studies, the Wender Utah Rating Scale for childhood ADHD, and the Zuckerman Seeking Sensation Scale. Results: We found significantly higher prevalence rates of probable childhood ADHD in CD versus NCD ( p < .001). The mean total scores of sensation seeking were significantly higher in CD versus NCD participants ( p < .001) as well as in CD patients with versus those without a probable history of childhood ADHD ( p < .001). Conclusion: Our study sets the basis for longitudinal investigation assessing whether the persistence of high level of sensation seeking in adults with childhood ADHD contributes to the transition to cocaine dependence.
