Tender points or tender patients? The value of the psychiatric in-depth interview for assessing and understanding psychopathological aspects of fibromyalgia.

Various assessment strategies have both strengths and weaknesses. Two case reports are presented which illustrate the value of the psychiatric in-depth interview (including psychodynamic-biographical history taking) for assessing and understanding psychological/psychiatric aspects of fibromyalgia.
