The recently developed Brief Esophageal Dysphagia Questionnaire (BEDQ) evaluates esophageal obstructive symptoms. Its initial evaluation showed strong psychometric properties. The aims of this study were to (a) translate and validate an international Spanish version of BEDQ and (b) evaluate its psychometric properties in a large Hispano-American sample of symptomatic individuals.
A Spanish BEDQ version was performed by Hispano-American experts using a Delphi process and reverse translation. Patients were prospectively recruited from seven centers in Spain and Latin America among individuals referred for high-resolution manometry (HRM). Patients completed several scores: Hospital Anxiety & Depression Scale (HADS), Eckardt score (ES), Gastroesophageal Reflux Questionnaire (GERDQ), and the BEDQ. Standardized psychometric analyses were performed.
A total of 426 patients were recruited. Spanish BEDQ showed excellent reliability (Cronbach's alpha = 0.91). Factor analysis confirmed its unidimensional character. Moderate significant correlations between BEDQ and other symptomatic scores were found, suggesting sufficient convergent validity. Patients with abnormal or obstructive HRM findings scored significantly higher when compared to normal or non-obstructive findings, respectively. Using a cutoff of 10, BEDQ showed a sensitivity of 65.38% and a specificity of 66.21% and an area under the curve of 0.71 for obstructive or major manometric diagnosis.
A widely usable Spanish BEDQ version has been validated. We confirm its excellent psychometric properties in our patients, confirming the appropriateness of its use in different populations.
新开发的简短食管吞咽困难问卷（BEDQ）评估食管梗阻症状。其初步评估显示出强大的心理测量学特性。本研究的目的是（a）翻译和验证 BEDQ 的国际西班牙语版本，以及（b）在有症状的西班牙裔美国人样本中评估其心理测量学特性。
西班牙裔美国专家使用德尔菲法和反向翻译来执行西班牙语 BEDQ 版本。患者前瞻性地从西班牙和拉丁美洲的七个中心招募，这些患者是因高分辨率测压术（HRM）而被转诊的。患者完成了几个评分：医院焦虑和抑郁量表（HADS）、Eckardt 评分（ES）、胃食管反流问卷（GERDQ）和 BEDQ。进行了标准化的心理测量分析。
共招募了 426 名患者。西班牙语 BEDQ 显示出极好的可靠性（Cronbach's alpha = 0.91）。因子分析证实了其单一维度特征。BEDQ 与其他症状评分之间存在中度显著相关性，表明具有足够的收敛有效性。与正常或非梗阻性 HRM 发现相比，异常或梗阻性 HRM 发现的患者得分明显更高。使用 10 的截断值，BEDQ 对梗阻或主要测压诊断的敏感性为 65.38%，特异性为 66.21%，曲线下面积为 0.71。
已经验证了一种广泛可用的西班牙语 BEDQ 版本。我们在我们的患者中确认了其出色的心理测量学特性，证实了其在不同人群中使用的适当性。
