Summary
Researchers developed a new interview to help diagnose conditions within the proposed affective spectrum disorder (ASD) family, including irritable bowel syndrome and chronic fatigue syndrome. This tool aims to aid further research into these interconnected conditions.
Area of Science:
- Psychiatry
- Neurology
- Gastroenterology
- Rheumatology
Background:
- Growing evidence suggests a link between various psychiatric and medical conditions.
- These conditions may represent a larger family of disorders, termed "affective spectrum disorder" (ASD).
Purpose of the Study:
- To develop a diagnostic tool for conditions potentially belonging to the affective spectrum disorder (ASD) family.
- To facilitate further research into the concept of ASD.
Main Methods:
- Seven interview modules were drafted in the format of the Structured Clinical Interview for DSM-III-R (SCID).
- Modules were designed to diagnose irritable bowel syndrome, narcolepsy, Tourette's disorder, migraine, fibromyalgia, chronic fatigue syndrome, and kleptomania.
- Operational diagnostic criteria were identified, and modules were refined with expert input.
Main Results:
- The complete supplemental interview is presented.
- Preliminary use in over 100 patients suggests the interview is reliable for diagnosing these disorders.
- Formal test-retest reliability assessment is pending.
Conclusions:
- The developed SCID-based interview is expected to aid future research on the epidemiology, pathogenesis, and treatment of affective spectrum disorder (ASD) conditions.
- This tool supports the investigation of potential connections between seemingly disparate psychiatric and medical disorders.
