The validity and reliability of the Inflammatory Bowel Disease Questionnaire (IBDQ) needed to be confirmed before its use in the UK.The IBDQ was administered to 28 subjects with ulcerative colitis (UC) on 3 separate occasions over a period of 4 weeks, twice by an interviewer and once by self-completion. Convergent and concurrent validity was assessed by using the Colitis Activity Index (CAI) and the Short Form 36 Health Survey (SF-36). Test-retest reliability and internal consistency were also tested.There were moderately high Pearson correlations between related IBDQ domains and SF-36 dimensions and also between the CAI score and the IBDQ Bowel domain and the SF-36 Pain dimension. Cronbach's alpha, corrected item-total correlations, and intra-class correlation coefficients were high.The IBDQ is a valid and reliable health-related quality of life scale for use in patients with UC and is suitable for use in the UK.
