Core mental state in irritable bowel syndrome

Area of Science:

• Gastroenterology
• Psychiatry
• Clinical Psychology

Background:

• Irritable Bowel Syndrome (IBS) is associated with higher rates of psychiatric illness.
• Specific psychopathology differentiating IBS from other gastrointestinal disorders remains unclear.
• Investigating predominant psychiatric symptoms in women with IBS is crucial for diagnosis and treatment.

Purpose of the Study:

• To identify and characterize predominant psychiatric symptoms in women diagnosed with IBS.
• To compare psychiatric profiles of women with IBS to those with chronic cholelithiasis.
• To determine if specific psychiatric symptoms predict IBS diagnosis.

Main Methods:

• Diagnosis of IBS used Manning et al. criteria, modified by Thompson et al.
• Psychiatric assessment involved structured interviews in 64 women (36 IBS, 28 chronic cholelithiasis).
• DSM-IV criteria and PSE-Index of Definition (ID) computer program (CATEGO) were used for psychopathology assessment.

Main Results:

• No significant differences in specific DSM-IV diagnostic categories between IBS and control groups.
• Higher prevalence of total depressive disorders observed in the IBS group.
• Duration of gastrointestinal pain, general anxiety, and hypochondriasis significantly predicted IBS diagnosis.

Conclusions:

• Female IBS patients fall under the general DSM-IV depressive disorder category.
• IBS patients exhibit higher current psychiatric severity compared to women with chronic cholelithiasis.
• General anxiety and hypochondriasis are characteristic psychiatric syndromes in women with IBS.
