Abstract

OBJECTIVES
This study aimed to investigate the psychosocial characteristics of functional gastrointestinal disorder (FGID) in patients with psychiatric disorders.
METHODS
This study was conducted with 144 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean, and State-Trait Anger Expression Inventory. Chi-squared test and student's t-test were used as statistical analysis methods.
RESULTS
There were differences in education level between two groups divided according to FGID status (χ²=10.139, p=0.017). Comparing the psychiatric disorder by FGID group, irritable bowel syndrome (IBS) group showed significant differences (χ²=11.408, p=0.022). According to FGID status, IBS group showed significant differences for anxiety (t=−3.106, p=0.002), depressive symptom (t=−2.105, p=0.037), somatic symptom (t=−3.565, p < 0.001), trait anger (t=−3.683, p < 0.001), anger-in (t=−2.463, p=0.015), and anger-out (t=− 2.355, p=0.020). Functional dyspepsia group showed significant differences for anxiety (t=−4.893, p < 0.001), depressive symptom (t=−3.459, p < 0.001), somatic symptom (t=−7.906, p < 0.001), trait-anger (t=−4.148, p < 0.001), state-anger (t=−2.181, p=0.031), anger-in (t=−2.684, p=0.008), and anger-out (t=−3.005, p=0.003). Nonerosive reflux disease group showed significant differences for anxiety (t=−4.286, p < 0.001), depressive symptom (t=−3.402, p < 0.001), somatic symptom (t=−7.162, p < 0.001), trait anger (t=−2.994, p=0.003), state anger (t=−2.259, p=0.025), anger-in (t=−2.772, p=0.006), and anger-out (t=−2.958, p=0.004).
CONCLUSIONS
Patients with psychiatric disorders had a high prevalence of FGID, and various psychosocial factors contributed to such differences. Therefore, the psychiatric approach can offer better understandings and treatments to patients with FGID.
