Abstract

Cocaine-dependent patients have high impulsiveness. Cocaine-induced psychosis is common among cocaine-dependent patients. Different risk factors associated with cocaine-induced psychosis have been reported. The aim of this study is to analyze the relationship between psychotic symptoms in cocaine-dependent patients and impulsivity and mental disorders characterized by impulsivity. This descriptive study included 287 outpatients with cocaine dependence according to the DSM-IV-TR criteria. The Structured Clinical Interview for DSM-IV Axis I and II, the Barratt Impulsiveness Scale, and a specific questionnaire on the presence of cocaine-induced psychosis were used to assess patients. Symptoms were observed in 59.9% of the study population. Total and cognitive impulsiveness scores obtained from the Barratt Impulsiveness Scale were significantly higher in patients with cocaine-induced psychosis. Individuals from this group reported more overdose incidents, initiated more treatments during their lifetime, and had a significantly greater prevalence of attention deficit hyperactivity disorder. Patients with cocaine-induced psychosis have a greater degree of impulsivity and a higher prevalence of attention deficit hyperactivity disorder. Thus, if these disorders are observed in cocaine-dependent participants, the presence of psychotic symptoms should be evaluated to prevent further occurrence and their consequences. © 2013 Taylor & Francis Group, LLC.
