Background: Inflammatory bowel diseases (IBDs) require self-management skills that may be influenced by self-efficacy (SE). Self-efficacy represents an individual's perception of his or her ability to organize and execute the behaviors necessary to manage disease. The goal of this study was to develop a valid and reliable measure of IBD-specific SE that can be used in clinical and research contexts.
Methods: One hundred and twenty-two adults with a verified IBD diagnosis participated in the study. Data were pooled from 2 sources: patients from an outpatient university gastroenterology clinic (n=42) and a sample of online respondents (n=80). All participants (N=122) completed the IBD Self-Efficacy Scale (IBD-SES) and the Inflammatory Bowel Disease Questionnaire. Additionally, online participants completed the Brief Symptom Inventory-18 and the Rosenberg Self-Esteem Scale, whereas those in the clinic sample completed the Perceived Health Competence Scale, the Perceived Stress Questionnaire, and the Short Form Version 2 Health Survey.
Results: The IBD-SES was initially constructed to identify 4 distinct theoretical domains of self-efficacy: (1) managing stress and emotions, (2) managing medical care, (3) managing symptoms and disease, and (4) maintaining remission. The 29-item IBD-SES has high internal consistency (r=0.96), high test-retest reliability (r=0.90), and demonstrates strong construct and concurrent validity with established measures.
Conclusions: The IBD-SES is a critical first step toward addressing an important psychological construct that could influence treatment outcomes in IBD.
