METHOD: Using modern item response theory, we examined the performances of the diagnostic criteria outlined by the DSM-IV and two sets of conceptual diagnostic criteria (the Endicott and the Cavanaugh criteria) in a series of 728 cancer patients who had been diagnosed with major depression using an inclusive approach. RESULTS: While all the DSM-IV diagnostic criteria, including feelings of worthlessness and suicidal ideation, had a low ability for discriminating the severity of depression, two proposed items (not participating in medical care and social withdrawal) appeared to be good markers of moderately severe major depressive disorder among cancer patients. In addition, the items "fearfulness or depressed appearance in face or body posture" and "brooding, self-pity or pessimism" may be good markers for mild major depressive disorders, while the item "cannot be cheered up, doesn't smile, no response to good news or funny situations" may be a good marker for severe major depressive disorder. CONCLUSIONS: The findings of the present study suggest that alternative criteria may have utility in diagnosing depression severity in cancer patients.
