Which Psychopathological Syndromes Could Be Associated with the Risk of Suicide among Substance Users?

Background: Research has shown that suicide is a highly present phenomenon among the drug dependent population. Moreover, individuals with substance use disorder (SUD) present high psychopathological comorbidity. This study aimed to describe which clinical syndromes are linked to the presence of risk of suicide. Methods: The study was based on a consecutive non-probabilistic convenience sample of 196 patients who attended the Public Addiction Center in Girona (Spain). Sociodemographic data, as well as suicide risk and drug related characteristics, were recorded. The risk of suicide was assessed with the Spanish version of "risk of suicide". Complicated grief was assessed with the Spanish version of the Inventory of Complicated Grief. Clinical syndromes were measured with the Spanish version of MCMI-III. Results: The syndromes most frequently associated with the presence of risk of suicide were complicated grief, major depression and thought disorder. Conclusions: Different psychopathological syndromes were identified in relation to risk of suicide among patients with SUD. The present results highlight the importance of accurately diagnosing those individuals.
