Screening for mental disorder among primary care patients. Usefulness of the General Health Questionnaire

Abstract

The General Health Questionnaire (GHQ) and a structured psychiatric interview (lifetime version of the Schedule for Affective Disorders and Schizophrenia) were administered to a sample of primary care patients in the United States. Responses to the GHQ tended to form factors that have substantive interpretations, such as depression, anxiety, sleep problems, and social functioning. However, there seems to be little gain in using subscale scores to help identify persons with different types of psychiatric disorders.
