title: A supplemental interview for forms of "affective spectrum disorder".
abstract: OBJECTIVE
  Recent evidence suggests that a number of psychiatric and medical conditions may be members or candidate members of a larger family of conditions, which we have termed "affective spectrum disorder (ASD)." In order to facilitate further research into this concept, we drafted seven interview modules, using the format of the Structured Clinical Interview for DSM-III-R (SCID), designed to diagnose the following psychiatric and medical disorders: irritable bowel syndrome, narcolepsy, Tourette's disorder, migraine, fibromyalgia, chronic fatigue syndrome, and kleptomania.
  
  
  METHODS
  Published operational diagnostic criteria for these seven disorders were sought in the literature. Questions in SCID format were then drafted in accordance with these operational criteria. Draft modules were then sent to experts familiar with each of the disorders and suggestions and revisions from these experts incorporated into the final modules.
  
  
  RESULTS
  The complete supplemental interview is presented with this report. Preliminary experience with this interview in more than 100 patients tentatively suggests that it is reliable for diagnosing the disorders in question; however, a formal test-retest reliability assessment is still required.
  
  
  CONCLUSIONS
  It is hoped that this supplemental interview, used in conjunction with the SCID, will be helpful in further studies of the epidemiology, pathogenesis, and treatment of these possible forms of affective spectrum disorder.
