Translating and cross-culturally adapting the CFAbd-Score, Cystic Fibrosis (CF) Abdominal Score, to use in Brazilian spoken Portuguese. The CFAbd-Score is a questionnaire for assessing CF-related abdominal symptoms and their influence on the quality of life (QoL). It comprises 28 questions on five domains: abdominal pain, bowel movements, eating and appetite, gastroesophageal reflux symptoms, and the impact of gastrointestinal (GI) symptoms on QoL.
Cross-cultural adaptation included assessment of conceptual and item equivalence, semantic, operational, and measurement equivalence. Content validity was assessed. The validation and psychometric analysis phase included 97 people with CF (pwCF), median age:14.58y (IQR 9/19), and 105 healthy individuals, 15.10y (IQR 9/20). Exploratory factor analysis (FA) identified retained factors. Internal consistency of the extracted domains was evaluated using Cronbach's α, and the Kaiser-Meyer-Olkin test (KMO) was used to check the sample adequacy. Bartlett's test tested the null hypothesis that the correlation matrix is an identity matrix.
All items were considered relevant to the construct and good semantic equivalence of the version was recognized. FA showed the appropriate weight of all items and good internal consistency, with Cronbach's alpha 0.89. Bartlett's test significance level (p < 0.001) and KMO coefficient of 0.72 indicated good adequacy for structure. Internal consistency coefficients (Cronbach's alpha) were good for abdominal pain: 0.84; abdominal bloating: 0.73; flatulence: 0.76; heartburn: 0.81, and low for reflux: 0.54.
The CFAbd-Score was adapted to the Brazilian spoken Portuguese and demonstrated content and semantic equivalence. The final version showed appropriate validity, and internal consistency, preserving the psychometric properties of the original version.
将囊性纤维化腹部评分（CFAbd-Score）翻译成巴西葡萄牙语并进行跨文化调适，以便在巴西使用。CFAbd-Score是一份用于评估与囊性纤维化（CF）相关的腹部症状及其对生活质量（QoL）影响的问卷。它包含28个关于五个领域的问题：腹痛、排便、饮食与食欲、胃食管反流症状以及胃肠道（GI）症状对生活质量的影响。
跨文化调适包括对概念和条目等效性、语义、操作和测量等效性的评估。评估了内容效度。验证和心理测量分析阶段纳入了97名囊性纤维化患者（pwCF），中位年龄：14.58岁（四分位间距9/19），以及105名健康个体，15.10岁（四分位间距9/20）。探索性因子分析（FA）确定保留的因子。使用克朗巴赫α系数评估提取领域的内部一致性，并使用凯泽-迈耶-奥尔金检验（KMO）检查样本充足性。巴特利特检验用于检验相关矩阵为单位矩阵的零假设。
所有条目均被认为与该结构相关，且该版本具有良好的语义等效性。因子分析显示所有条目的权重合适且内部一致性良好，克朗巴赫α系数为0.89。巴特利特检验的显著性水平（p < 0.001）和KMO系数为0.72表明结构的充足性良好。腹痛的内部一致性系数（克朗巴赫α系数）良好：0.84；腹胀：0.73；肠胃胀气：0.76；烧心：0.81，而反流的系数较低：0.54。
CFAbd-Score已调适为巴西葡萄牙语，并显示出内容和语义等效性。最终版本显示出适当的效度和内部一致性，保留了原始版本的心理测量特性。
