背景：慢性胃肠道（GI）症状被认为是普通人群中常见的，但缺乏澳大利亚的数据。一个有效的工具是需要充分评估胃肠道症状，并确定其患病率在community.Aims：测试的可行性，可靠性和并行效度的自我报告肠道症状问卷（BSQ）作为衡量胃肠道症状，并获得初步数据的患病率症状在澳大利亚人口为基础的样本。悉尼Penrith人群的门诊患者（n = 63）、志愿者（n = 163）和随机样本（n = 99）完成了BSQ。在264名受试者中评估了可行性。通过重测程序（n = 43）来测量可靠性，同时通过将自我报告数据与独立访谈（n = 20）进行比较来记录并行效度。人口邮件调查的答复率为68%。在社区样本（n = 99）的肠道症状的患病率数据的年龄和性别标准化的澳大利亚population.Results：大多数受试者发现BSQ容易完成（97%）和理解（97%）; 90%的人在半小时或更短的时间内完成了问卷调查。可靠性（中位数kappa 0.70，四分位距0.20）和同时效度（中位数kappa 0.79，四分位距0.26）均非常可接受。所有GI症状量表的内部一致性良好（Cronbach α范围为0.51-0.74）。肠易激综合征（定义为腹痛和排便障碍的基础上两个或两个以上的曼宁标准）的患病率为17.2%（95%CI：10-25%）。结论：BSQ是公认的，易于理解，它提供了可靠和有效的数据胃肠道症状，并应证明在澳大利亚的大规模流行病学研究是有用的。
Background: Chronic gastrointestinal (GI) symptoms are believed to be common in the general population, but Australian data are lacking. A valid instrument is required to assess GI symptoms adequately and determine their prevalence in the community.Aims: To test the feasibility, reliability and concurrent validity of a self-report Bowel Symptom Questionnaire (BSQ) as a measure of GI symptoms, and obtain preliminary data on the prevalence of symptoms in an Australian population-based sample.Methods: Outpatients (n = 63), volunteers (n = 163) and a random sample (n = 99) of the Penrith population, Sydney, completed the BSQ. Feasibility was evaluated in 264 subjects. Reliability was measured by a test retest procedure (n = 43), while concurrent validity was documented by comparing self-report data with an independent interview (n = 20). The response rate in the population mail survey was 68%. Prevalence data on bowel symptoms in the community sample (n = 99) were age and gender standardised to the Australian population.Results: The majority of subjects found the BSQ easy to complete (97%) and understand (97%); 90% completed the questionnaire in half an hour or less. Reliability (median kappa 0.70, interquartile range 0.20) and concurrent validity (median kappa 0.79, interquartile range 0.26) of GI symptoms were both very acceptable. The internal consistency of all GI symptom scales was good (Cronbach's Alpha range 0.51-0.74). The prevalence of the irritable bowel syndrome (defined as abdominal pain and disturbed defaecation based on two or more of the Manning criteria) was 17.2% (95% CI: 10-25%).Conclusions: The BSQ was well accepted and easy to understand; it provided reliable and valid data on GI symptoms and should prove useful in large scale epidemiological studies in Australia.
