Psychiatric comorbidity in a sample of cocaine-dependent outpatients seen in the Community of Madrid drug addiction care network. Adicciones. 28 – 1, pp. 6 – 24. 2016. ISSN 0214-4840.
The objective of this study was to estimate the current prevalence of psychiatric disorders in cocaine-dependent patients who attend different treatment centres in the Community of Madrid. A prospective multicentre study was used, and a total of 197 cocaine-dependent subjects were assessed. The assessment instrument used for diagnosis was the Psychiatric Research Interview for Substance and Mental Disorders (PRISM-IV). The main findings of this study were a high prevalence of psychiatric comorbidity in cocaine-dependent patients seeking treatment (64.0%). The most common Non Substance Use Disorders found were attention-deficit/hyperactivity Disorders (34.5%) and depressive disorders (13.7%). The most common Substance Use Disorder was alcohol dependence (28.4%). Cocaine-dependent patients who had a depressive disorder and were alcohol dependent presented a more severe clinical profile and a higher degree of psychopathology, measured using different assessment tools, than the patients who were only cocaine dependent. These data suggest that the presence of psychiatric comorbidity could constitute a risk factor associated with the severity of cocaine dependence. The clinical heterogeneity found also indicates the need to search for individualised treatments that more specifically fit the needs of this population.
