This study investigated the impact of gastrointestinal-specific anxiety (GSA) on symptom management of irritable bowel syndrome (IBS) by examining predictors of IBS symptom severity. Additionally, GSA is divided into maladaptive cognition and dysfunctional behavior to verify their mediating effects on IBS symptom severity. A total of 109 university students were classified into IBS and non-IBS groups based on the Rome III criteria. Comparisons between the two groups were then conducted. Results showed that dysfunctional behavior significantly predicted IBS symptom severity in the IBS group, but not in the non-IBS group. In addition, dysfunctional behavior fully mediated the relationship between maladaptive cognition and IBS symptom severity in the IBS group. This study is significant in that it provides more detailed foundational information related to IBS symptom management by distinguishing between cognitive and behavioral components of GSA.
