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.
炎症性肠病问卷（IBDQ）在英国使用之前，其有效性和可靠性需要得到确认。
在4周的时间内，对28名溃疡性结肠炎（UC）患者分3次进行IBDQ问卷调查，其中两次由访员进行询问，一次由患者自行填写。通过使用结肠炎活动指数（CAI）和简短健康调查问卷（SF-36）评估聚合效度和并发效度。同时也测试了重测信度和内部一致性。
IBDQ相关领域与SF-36维度之间以及CAI评分与IBDQ肠道领域和SF-36疼痛维度之间存在中等程度的高皮尔逊相关性。克朗巴哈系数、校正后的项目-总分相关性和组内相关系数都很高。
IBDQ是一种有效且可靠的与健康相关的生活质量量表，适用于UC患者，也适合在英国使用。
