Testing a somatization hypothesis to explain the Black–White depression paradox

Purpose Epidemiologic studies document a lower prevalence of major depression in Blacks than Whites in the United States. This is paradoxical from the perspective of social stress theory. A long-standing claim in the (clinical) literature is that Blacks express depression more somatically than Whites. If true, the diagnostic algorithm may undercount depression in Blacks, since the screening symptoms privilege the psychological rather than somatic dimensions of depression. We test hypotheses that (1) Blacks express depression more somatically than Whites which (2) reduces their likelihood of endorsing screening symptoms, thereby undercounting Blacks’ depression and explaining the Black–White depression paradox.
