Evaluation of a new quality of life questionnaire for patients with irritable bowel syndrome.
We describe the development and evaluation of a new disease-specific instrument, the Irritable Bowel Syndrome Quality of Life Questionnaire (IBSQOL), which was designed for use in patients with irritable bowel syndrome.
The IBSQOL measures 1 () domains found to be relevant to patients with irritable bowel syndrome : emotional health, mental health, health belief, sleep, energy, physical functioning, diet, social role, physical role, and sexual relations.
During its development and evaluation, the IBSQOL was administered to over 5 () () patients with irritable bowel syndrome-two groups of patients from tertiary care centres, three focus groups of 8-12 patients each, and 287 patients in a national irritable bowel syndrome support network.
As a control, the IBSQOL was also administered to 37 patients who did not have irritable bowel syndrome but had other gastrointestinal disorders.
Statistical analyses to test the reliability and validity of the IBSQOL were performed using Cronbach's alpha coefficient.
Responses from the focus groups indicated that the IBSQOL was easy to complete and did not require too much time to fill out (25 min).
Statistical analyses of the final 30-item version of the IBSQOL demonstrated that it had both adequate validity and reliability (alpha = 0.60). (...)
