American Urological Association guidelines suggest dietary changes as first line treatment for interstitial cystitis/bladder pain syndrome. We previously developed a validated survey instrument to determine which foods, beverages and supplements exacerbate the symptoms of this condition. In this study we developed a shortened questionnaire that would provide an easily self-administered food symptom history useful for clinical practice and future research.
Using data from our previously validated food sensitivity questionnaire we remodeled the original lengthy survey to an abbreviated list including the 35 most problematic comestibles. The instrument was reviewed by a panel of experts for face and content validity, and tested for internal consistency, readability and clarity, and test-retest reliability.
Of the 124 patients who completed a baseline questionnaire 52 (42%) returned the second instrument 1 week after completing the first instrument. Internal consistency was high (α=0.96). A total of 47 patients (90.4%) indicated that they were food sensitive. Questionnaire test-retest reliability assessed by the Spearman correlation coefficient ranged from moderate (ρ=0.48 for Equal®) to very strong (ρ=0.90 for beer). Discrepancies between the survey instruments in individual comestibles occurred only 1% of the time.
Our short form diet history questionnaire based on a previously validated long form is a reliable, newly validated instrument that will help identify comestibles associated with interstitial cystitis/bladder pain syndrome symptoms. Its brevity makes it simple to administer and useful for dietary management in this population.
美国泌尿外科学会指南建议将饮食改变作为间质性膀胱炎/膀胱疼痛综合征的一线治疗方法。我们之前开发了一种经过验证的调查问卷工具，以确定哪些食物、饮料和补充剂会加重这种疾病的症状。在本研究中，我们开发了一份简短的问卷，该问卷将提供一份易于自我管理的食物症状史，对临床实践和未来研究有用。
利用我们之前经过验证的食物敏感性调查问卷的数据，我们将原来冗长的调查问卷重塑为一份简短列表，其中包括35种最有问题的食物。该工具由一组专家进行了面部和内容效度审查，并测试了内部一致性、可读性和清晰度以及重测信度。
在完成基线问卷的124名患者中，有52名（42%）在完成第一份问卷1周后返回了第二份问卷。内部一致性很高（α=0.96）。共有47名患者（90.4%）表示他们对食物敏感。通过Spearman相关系数评估的问卷重测信度从中度（Equal®的ρ=。48）到非常强（啤酒的ρ=0.90）不等。个体食物中调查问卷工具之间的差异仅在1%的时间出现。
我们基于之前经过验证的长格式问卷的简短饮食史问卷是一种可靠的、新验证的工具，将有助于识别与间质性膀胱炎/膀胱疼痛综合征症状相关的食物。其简洁性使其易于管理，对该人群的饮食管理有用。
