Oncologists' recognition of depression in their patients with cancer.

Abstract

Physicians' perceptions of depressive symptoms in their patients are correlated with patient's ratings, but there is a marked tendency to underestimate the level of depressive symptoms in patients who are more depressed. They are most influenced by symptoms such as crying and depressed mood, and medical factors that are useful, but not the most reliable, indicators of depression in this population. Physicians' ratings of their patients' distress symptoms seem to be global in nature--they are highly correlated with anxiety, pain, and global dysfunction. Physician assessment might be improved if they were instructed to assess and probe for the more reliable cognitive symptoms such as anhedonia, guilt, suicidal thinking, and hopelessness. Screening instruments and the use of brief follow-up interviews would help to identify patients who are depressed.
