The epidemiology of co-occurring addictive and mental disorders: Implications for prevention and service utilization

Data from the National Comorbidity Survey were examined to determine (1) the prevalence of co-occurring addictive and mental disorders, (2) the temporal relationships between these disorders, and (3) the extent to which 12-mo co-occurrence is associated with use of services. Data were collected from 5,877 respondents. Co-occurrence was highly prevalent and usually due to the association of a primary mental disorder with a secondary addictive disorder. Co-occurrence was associated with a significantly increased probability of treatment. However, fewer than half of cases with 12-mo co-occurrence received any treatment in the year prior to interview, suggesting a need for greater outreach efforts.
