The US National Comorbidity Survey: Overview and future directions

This report presents an overview of the results of the US National Comorbidity Survey (NCS) (Kessler et al., 1994) and future directions based on these results. The NCS is a survey that was mandated by the US Congress to study the comorbidity of substance abuse disorders and nonsubstance psychiatric disorders in the general population of the US. It is the first survey to administer a structured psychiatric interview for DSM-III-R disorders to a representative national sample in the US. (1997)
