The purpose of our study was to develop a quality-of-life (QoL) questionnaire for patients with gastroesophageal reflux disease (GERD) who have undergone laparoscopic fundoplication. This questionnaire was developed to be more comprehensive than existing measures.
Between 1994 and 2002, 252 patients underwent laparoscopic fundoplication for GERD in the 1st Department of Surgery, Semmelweis University. We undertook a retrospective analysis: each of 252 operated patients was given a questionnaire and was requested to complete it and return it in an enclosed envelope. A total of 116 patients returned completed questionnaires. The patients included 55 men and 61 women, with a mean age of 46 years (range 14-77). These patients were used in the psychometric evaluation. The questionnaire consisted of 50 questions (including the Visick score, EORTC-QLQ-C30, and a modified GERD-HRQL).
Internal consistency reliability was high (alpha value overall, 0.95, range, 0.74-0.96). Using convergent and divergent validity, construct validity was evaluated by examining Pearson correlation coefficients between items and scales. Construct validity was demonstrated based on observed correlations. Known groups validity was upheld because patients who experienced more symptoms and patients who has higher Visick scores reported worse QoL than those with less symptoms or lower Visick scores.
Our questionnaire is a short and user-friendly instrument with excellent psychometric properties. It has been found to be valid and reliable.
我们研究的目的是为接受腹腔镜胃底折叠术的胃食管反流病（GERD）患者开发一份生活质量（QoL）问卷。该问卷的设计比现有测量方法更全面。
1994年至2002年间，塞梅尔维斯大学第一外科的252例患者因GERD接受了腹腔镜胃底折叠术。我们进行了一项回顾性分析：给252例接受手术的患者每人发放一份问卷，并要求他们填写后装在随附的信封中寄回。共有116例患者寄回了完整的问卷。这些患者包括55名男性和61名女性，平均年龄46岁（范围14 - 77岁）。这些患者用于心理测量评估。问卷由50个问题组成（包括Visick评分、欧洲癌症研究与治疗组织生活质量核心问卷（EORTC - QLQ - C30）以及改良的GERD - HRQL）。
内部一致性信度较高（总体α值为0.95，范围为0.74 - 0.96）。通过使用收敛效度和区分效度，通过检查项目与量表之间的皮尔逊相关系数来评估结构效度。基于观察到的相关性证明了结构效度。已知组效度得到支持，因为经历更多症状的患者和Visick评分较高的患者报告的生活质量比症状较少或Visick评分较低的患者更差。
我们的问卷是一种简短且用户友好的工具，具有出色的心理测量特性。已发现它有效且可靠。
