Psychometric evaluation of an online and paper accidental bowel leakage questionnaire: The ICIQ-B questionnaire

Academic Article


  • Aims: To evaluate the psychometric properties of an online versus paper US-English version of the International Consultation on Incontinence Questionnaire-Bowel (ICIQ-B). Methods: The ICIQ-B includes 17 items under 3 domains: bowel pattern (5 items), bowel control (7 items), and quality of life (5 items). We recruited community-dwelling adults seeking treatment for ≥monthly bowel leakage from specialty clinics within a VA medical center and university affiliate. An online versus paper version was evaluated at baseline, 2 weeks later, and 3 months after nonsurgical treatments per usual care. We assessed test-retest reliability (Pearson correlations) at 2 weeks, internal consistency (Cronbach's alpha), and convergent validity (Pearson correlations). Sensitivity to change was the difference between the baseline and post-treatment (3-month) scores. Results: Mean age was 58.0 ± 11.9; 36% Veterans, 52% women. At baseline, 2 weeks, and 3 months, we found no differences in the online vs paper scores for the bowel control and quality of life domains. The ICIQ-B demonstrated fair internal consistency for the bowel pattern domain (Cronbach's α = 0.36–0.54). Internal consistency on the bowel pattern domain was better with the paper version than the online version at 2 weeks (P < 0.05) and 3 months (P < 0.01) with no difference at baseline. All other domains had good internal consistency (Cronbach's α > 0.80), good retest reliability (r ≥ 0.70, P < 0.001), domain-specific convergent validity for stool consistency (P < 0.05), incontinence severity (P ≤ 0.002), and quality of life impact (P < 0.05). After nonsurgical treatments, we found a reasonable response to change (P ≤ 0.05). Conclusions: Online and paper versions had robust psychometric data for use among U.S. men and women, including Veterans. Neurourol. Urodynam. 36:166–170, 2017. © 2015 Wiley Periodicals, Inc.
