The terms somatoform disorder and functional disorder have been criticized for hindering rather than facilitating clinical communication, and physicians may rarely use these terms when communicating with patients who might be eligible for these diagnoses. However, no study has yet examined the extent to which patients at risk for these disorders are familiar with the diagnostic terms. Therefore, the primary aim of this study was to examine whether people at risk for a somatoform disorder (ie, those with medically unexplained somatic symptoms) are more familiar with the 2 terms than others.
