The role of cognitive emotion regulation strategies in predicting the resilience, symptom severity, and quality of life of patients with irritable bowel syndrome.

Background: Psychosocial stressors contribute to the development of irritable bowel syndrome (IBS) and exacerbate the symptoms. The capability to cope with stress is an essential element in the management of IBS. This study assessed nine cognitive emotion regulation strategies (CERS) and their role in predicting symptom severity, quality of life (QOL), and resilience in IBS subjects.

Methods: The scores regarding nine subscales of CERS were obtained by cognitive emotion regulation questionnaire (CERQ) and compared between study patients based on the severity and subtypes of IBS using one-way ANOVA. To evaluate the predictive role of CERS, logistic regression was performed. The correlation between CERS and the QOL was assessed by Pearson correlation analysis. The score of resilience was measured by Connor-Davidson Resilience Scale (CD-RISC).

Results: We recruited 100 patients diagnosed with IBS based on ROME IV criteria. Among nine subscales of CERS, patients with more severe symptoms scored higher in catastrophizing (p < 0.001) and blaming others (p = 0.015) while lower in positive reappraisal (p = 0.028). Blaming others was the only predictor of resilience and severity of IBS in our patients (odds ratio (OR): -2.103, p=0.028, and OR:1.715, p = 0.049, respectively). We observed significant negative correlations between the quality of life and rumination (r= -0.202, p=0.044), self-blame (r= -0.241, p=0.016), catastrophizing (r= -0.342, p<0.001), and blaming others (r= -0.219, p=0.028).

Conclusion: Maladaptive strategies are more common in IBS patients with more severe symptoms and have negative correlations with the QOL. Blaming others has the potential to predict the resilience and severity of symptoms in IBS patients.
