摘　　要：目的建立胃肠认知与行为指数(GCBI)量表并进行临床初测研究,为评估我国居民的胃肠相关认知及行为提供科学工具。方法通过文献查阅、专家评议等方式形成GCBI初量表。采用方便取样法选取2022年1月1日至12月31日于常州市第一人民医院就诊和健康体检的323名健康受试者进行GCBI初量表测试。共回收有效量表307份,采用方便取样法选取其中98名进行胃肠道生活质量指数(GIQLI)量表测试,2周后采用随机数字表法选取这307名健康受试者中的50名进行GCBI初量表重测。采用主成分分析法抽取因子数,建立正式GCBI量表。采用方便取样法选择2023年3月1日至5月31日于常州市第一人民医院就诊的40例功能性胃肠病(FGID)患者(FGID组)和40名健康人群(健康对照组)进行GCBI正式量表测试。采用Pearson相关分析和Cronbach′sα系数对量表进行效标效度和信度检验。采用秩和检验比较FGID组与健康对照组的GCBI量表总分及各因子分。结果通过主成分分析法最终抽取2个因子(包含7个条目)建立GCBI正式量表,因子1和因子2的累积贡献率为84.30%,因子负荷值为0.721~0.913。Pearson相关分析显示,GCBI量表总分、各因子与GIQLI量表的总分、各因子均呈负相关(均P<0.001)。GCBI总量表、因子1、因子2的Cronbach′sα系数分别为0.90、0.87、0.91,重测信度相关系数r=0.98、0.97、0.99(均P<0.001)。FGID组GCBI总分和因子1、2分值均高于健康对照组[10.00(7.25,13.25)分比2.00(0.25,3.00)分、5.00(3.25,8.00)分比0.50(0,2.00)分、5.00(3.00,6.00)分比0.50(0,2.00)分],差异均有统计学意义(Z=7.42、6.82、7.04,均P<0.001)。结论本研究建立的GCBI量表具有良好的信度和效度,适用于测评胃肠相关认知与行为,且有助于诊断FGID。Objective To establish the gastrointestinal cognition behavior index(GCBI)scale and conduct a preliminary clinical study,to provide a scientific tool for assessing gastrointestinal related cognition and behavior among Chinese residents.Methods The initial GCBI scale was formed through literature review and experts′evaluation.From January 1 to December 31,2022,323 healthy participants who received medical treatment or check-ups at the First People′s Hospital of Changzhou were selected by convenient sampling method for the initial GCBI scale.A total of 307 valid scales of GCBI were collected,and 98 of them were selected by convenient sampling method for the gastrointestinal quality of life index(GIQLI)scale test.A total of 50 participants of 307 were selected by random number table method for retesting the initial GCBI scale after 2 weeks.The principal component analysis was used for factor extraction to established the formal GCBI scale.From March 1 to May 31,2023,at the First People′s Hospital of Changzhou,40 patients with functional gastrointestinal disorder(FGID,FGID group)and 40 healthy individuals(healthy control group)were selected by convenient sampling method for formal GCBI scale test.Pearson correlation analysis and Cronbach′sαcoefficient were used to evaluate the criterion validity and reliability of the scale.Rank-sum test was used to compare the total GCBI scale scores and factor scores between the FGID group and the healthy control group.Results The results of principal component analysis showed that 2 factors and 7 items were finally extracted to establish the formal GCBI scale.The cumulative contribution rate of factor 1 and factor 2 was 84.30%,and the factor load values ranged from 0.721 to 0.913.Pearson correlation analysis showed that the total score of GCBI scale and each factor were negatively correlated with the total score and each factor of GIQLI scale(all P<0.001).The Cronbach′sαcoefficient of the total GCBI scale,factor 1,and factor 2 were 0.90,0.87,and 0.91,respectively.The t
