Comparative StudyPain in somatoform disorders: is somatoform pain disorder a valid diagnosis?
Investigate the validity of DSM-IIIR somatoform pain disorder (SPD) by comparing subgroups of somatoform disorder patients on several measures of psychopathology. ⋯ Significant diagnostic and symptomatic overlap was found between SPD and CD, and although the statistical power of the study was modest, the study questions the validity of the current definition of SPD.
