目的：开发一种经过语言学和心理测量学验证的英式英语(uk ！爱尔兰)版的糖尿病特异性生活质量量表（DSQOLS），用于成人1型糖尿病。研究设计和方法：我们对经过验证的德文DSQOLS进行了独立的正向和反向翻译。一项针对卫生专业人员（n = 3）和1型糖尿病成人（n = 8）的迭代访谈研究证实了语言效度。DSQOLS纳入三个正常饮食剂量调整（DAFNE）研究（总N = 1,071）。采用探索性因子分析（EFA）对问卷结构进行检验。并发效度和判别效度、内部一致性和信度进行了评估。结果：efa显示DSQOLS的六因素结构（社会方面、对低血糖的恐惧、饮食限制、身体抱怨、对未来的焦虑和日常烦恼）。这些因素和加权治疗满意度量表具有较高的内部一致性信度（alpha = 0.85 ~ 0.94）。所有量表均与糖尿病依赖生活质量审计（ADDQoL）测量呈正相关，证明了并发效度的证据。较低的DSQOLS亚量表得分[表明生活质量受损（Qol）]与糖尿病相关并发症的存在相关。结论：DSQOLS反映了现代1型糖尿病管理细节方面的影响（例如，碳水化合物计数和灵活的胰岛素剂量调整），这些在英国和爱尔兰的许多地区已经成为常规。英国英文版的DSQOLS为评估治疗方法对成人1型糖尿病患者生活质量的影响提供了一个有价值的工具。
OBJECTIVE-To develop a linguistically and psychometrically validated U.K. English (U.K.! Ireland) version of the Diabetes-Specific Quality-of-Life Scale (DSQOLS) for adults with type 1 diabetes.RESEARCH DESIGN AND METHODS-We conducted independent forward and backward translation of the validated German DSQOLS. An iterative interview study with health professionals (n = 3) and adults with type 1 diabetes (n = 8) established linguistic validity. The DSQOLS was included in three Dose Adjustment for Normal Eating (DAFNE) studies (total N = 1,071). Exploratory factor analysis (EFA) was undertaken to examine questionnaire structure. Concurrent and discriminant validity, internal consistency, and reliability were assessed.RESULTS-EFA indicated a six-factor structure for the DSQOLS (social aspects, fear of hypoglycemia, dietary restrictions, physical complaints, anxiety about the future, and daily hassles). High internal consistency reliability was found for these factors and the weighted treatment satisfaction scale (alpha = 0.85-0.94). All subscales were moderately, positively correlated with the Audit of Diabetes-Dependent Quality-of-Life (ADDQoL) measure, demonstrating evidence of concurrent validity. Lower DSQOLS subscale scores [indicating impaired quality of life (Qol)] were associated with the presence of diabetes-related complications.CONCLUSIONS-The DSQOLS captures the impact of detailed aspects of modem type 1 diabetes management (e.g., carbohydrate counting and flexible insulin dose adjustment) that are now routine in many parts of the U.K. and Ireland. The U.K. English version of the DSQOLS offers a valuable tool for assessing the impact of treatment approaches on QoL in adults with type 1 diabetes.
