Substance disorder treatments, especially when integrated with psychiatric treatments, have shown promising results in improving the outcomes of patients with comorbid substance and psychiatric disorders [15, 16]. However, relatively little is known about the usual pattern of care and barriers to care for these comorbid conditions in community settings. Past research has found a higher prevalence of treatment seeking among individuals with comorbid disorders [17], perhaps reflecting the greater severity of substance use disorders in these individuals. Past research has also identified a higher prevalence of perceived unmet need for care in individuals with comorbid conditions [18, 19], suggesting that individuals with these comorbid conditions may either face a different set of barriers or a greater number of barriers to treatment.
