Recognition of depression by internists in primary care: a comparison of internist and "gold standard" psychiatric assessments

Abstract

In an effort to elucidate the process of internists' recognition of depression in primary care settings, a comparison of internist and "gold standard" psychiatric assessments of patients was undertaken in a rural primary care practice over a 15-month period. Clinical characteristics and diagnoses, global assessments of psychosocial stress, and two aspects of chief-complaint presentation style, clarity and somatization, were recorded by the internists for each patient, who was independently assessed by a psychiatrist for the presence of any specific depressive disorder by structured interview. Internists correctly labeled 57% of the interview-assessed depressives as depressed; 13% of patients with "no psychiatric disorder" were assessed as depressed by internists. Clinical and demographic characteristics of the "false-negative" and "false-positive" internists' diagnoses were examined to clarify how internists think of "depression" in the primary care context.
