Abdominal bloating (AB) is a prevalent and bothersome symptom, but there are no specific measures for severity and quality of life (QoL) other than the Bloating Severity Questionnaire (BSQ) and Bloating Quality of Life (BLQoL). We aimed to translate the BSQ and BLQoL into the Malay language and to validate them using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) approaches. The 12-item BSQ has two components, seven-item severity in general (SevGen) and five-item severity in the past 24 h (Sev24), and BLQOL has five items. Translation to the Malay language (BSQ-M and BLQoL-M) was performed using standard forward and backward processes. EFA followed by CFA were performed in participants with AB due to functional bowel disorders, with the purpose of examining the validity and reliability of the questionnaires translated into Malay. After EFA with 152 participants, all the items of BSQ-M remained in the model. Total variance extracted was 53.26% for BSQ-M and 58.79% for BLQoL-M. The internal consistency based on Cronbach's alpha values was 0.52 for SevGen, 0.86 for Sev24, and 0.81 for BLQoL-M. After performing CFA with another 323 participants, the final measurement model for BSQ-M and BLQoL-M fit the data well in terms of several fit indices (BSQ-M: root mean square error of approximation (RMSEA) = 0.050, Comparative Fit Index (CFI) = 0.966, Tucker-Lewis Fit Index (TLI) = 0.956, and standardized root mean squared residual (SRMR) = 0.051; BLQoL-M: RMSEA = 0.071, CFI = 0.985, TLI = 0.962, SRMR = 0.021). The composite reliability for BSQ-M and BLQoL-M were satisfactory (SevGen = 0.83, Sev24 = 0.89, BLQoL = 0.80). The intraclass correlation (ICC) results showed excellent stability for BSQ-M and BLQoL-M, ranging from 0.74 to 0.93. The Malay language versions of BSQ-M and BLQoL-M are valid and reliable instruments for measuring the severity and QoL of AB for the Asian population with functional bowel disorders.
腹胀（AB）是一种普遍且令人困扰的症状，但除了腹胀严重程度问卷（BSQ）和腹胀生活质量问卷（BLQoL）之外，没有针对其严重程度和生活质量（QoL）的特定测量方法。我们旨在将 BSQ 和 BLQoL 翻译成马来语，并通过探索性因素分析（EFA）和验证性因素分析（CFA）方法验证其有效性。BSQ 由 12 个项目组成，包括两个分量表，一个是 7 个项目的一般严重程度（SevGen），另一个是过去 24 小时的 5 个项目严重程度（Sev24），BLQoL 则由 5 个项目组成。使用标准的正向和反向翻译过程将 BSQ 和 BLQoL 翻译成马来语（BSQ-M 和 BLQoL-M）。在功能性肠病导致 AB 的参与者中进行 EFA 后，进行 CFA，以检验翻译成马来语的问卷的有效性和可靠性。在对 152 名参与者进行 EFA 后，BSQ-M 的所有项目均保留在模型中。BSQ-M 的总方差提取率为 53.26%，BLQoL-M 的总方差提取率为 58.79%。基于 Cronbach's alpha 值的内部一致性为 SevGen 为 0.52，Sev24 为 0.86，BLQoL-M 为 0.81。在对另外 323 名参与者进行 CFA 后，BSQ-M 和 BLQoL-M 的最终测量模型在多个拟合指数方面都很好地拟合了数据（BSQ-M：均方根误差近似值（RMSEA）= 0.050，比较拟合指数（CFI）= 0.966，Tucker-Lewis 拟合指数（TLI）= 0.956，标准化均方根残差（SRMR）= 0.051；BLQoL-M：RMSEA = 0.071，CFI = 0.985，TLI = 0.962，SRMR = 0.021）。BSQ-M 和 BLQoL-M 的组合可靠性令人满意（SevGen = 0.83，Sev24 = 0.89，BLQoL = 0.80）。BSQ-M 和 BLQoL-M 的组内相关（ICC）结果显示出极好的稳定性，范围为 0.74 至 0.93。BSQ-M 和 BLQoL-M 的马来语版本是用于测量亚洲功能性肠病患者 AB 严重程度和生活质量的有效且可靠的工具。
