Background:
Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder, often exacerbated by psychological stress. Psychological self-efficacy and coping styles may influence the relationship between stress and symptom severity.
Objective:
This study aimed to examine the mediating roles of psychological self-efficacy and coping styles in the association between perceived stress and IBS symptom severity.
Methods:
In a cross-sectional design, 300 IBS patients from Tehran (2025) were recruited via convenience sampling. Participants completed validated Persian questionnaires assessing perceived stress, psychological self-efficacy, coping styles, and IBS symptom severity. Data were analyzed using multiple regression and mediation analysis following Baron and Kenny's approach.
Results:
Perceived stress showed a significant direct positive association with IBS symptom severity (P < 0.001). Additionally, psychological self-efficacy and coping styles partially mediated this relationship, accounting for a significant indirect effect (P < 0.01). Decreased self-efficacy and maladaptive coping were linked to greater symptom severity.
Conclusion:
Enhancing psychological self-efficacy and promoting adaptive coping strategies could be effective targets for psychological interventions aiming to reduce IBS symptom severity.
