The Structure of the DSM

Arch Gen Psychiatry. 2002;59(6):569-570. doi:

In his article on the structure of common mental disorders, Krueger1 reports on the analysis of comorbidity data obtained in a sample of 8098 noninstitutionalized US civilians in the National Comorbidity Survey. The analysis is carried out using confirmatory factor analysis. The confirmatory factor analysis yields a 3-factor model that accounts reasonably well for the obtained covariance between several mental disorders. This leads Krueger to conclude that "The results offer a novel perspective on comorbidity, suggesting that comorbidity results from common, underlying core psychopathological processes."1(p921)
