A Pilot, Proof-of-concept Cohort Study of the Prevalence of Comorbid Mental Illness and Substance Abuse

Completed

Conditions studied: Schizophrenia, Drug Abuse, Anxiety Disorder, Bipolar Disorder, Major Depression

In brief

The prevalence estimates for specific mental disorders and illicit drugs have been separately reported in U.S. government surveys. Less is known about the rates for specific comorbid conditions, e.g., schizophrenia and substance abuse, major depression and substance abuse, bipolar disorder and substance abuse, and anxiety disorder and substance abuse. The effects that different demographic characteristics (ethnic background, family medical history, age, living conditions \[e.g., living with a single parent\]) have on the prevalence of comorbid mental illness and substance abuse also have not been considered. More should be known about the duration of substance abuse in different mental illnesses among those undergoing treatment, and whether specific types of drugs are associated with specific mental illnesses. In this study, Advanced Clinical Laboratory Solutions, Inc. will investigate the prevalence rates for the specific comorbid conditions and demographic relationships described above. This multi-site, proof-of-concept cohort study will analyze urine or oral fluid samples from 1,000 subjects diagnosed with one of four mental illnesses (schizophrenia, major depression, bipolar disorder, or anxiety disorder) as determined by DSM-IV (The Fourth Edition of the Diagnostic and Statistical Manual of Mental Disorders). The samples will be analyzed for both prescription drug compliance and illicit substance abuse. Urine or oral fluid samples will be collected at three time points: 1) immediately after enrollment and obtaining informed consent, 2) randomly within 2 to 4 months of the study, and 3) at the end of the study (6 months).
