OBJECTIVE
To analyze the validity, reliability and interpretability of a short form instrument for assessing health-related quality of life among people with diabetes mellitus.
METHODS
This was a validation study, comprised of the adaptation phases of the Diabetes-39 instrument (consisting of 5 domains and 39 items), pre-test, structural validity analyses (exploratory and confirmatory), reliability, concurrent validity and interpretability.
RESULTS
The factorial structure of the short final version differed from the original instrument. The items were reduced from 39 to 21 and domains from 5 to 4. The factor loading, in exploratory and confirmatory analyses, ranged between 0.41 and 0.90 and between 0.51 and 0.89, respectively. Reliability was adequate (Cronbach's alpha=0.91; Kappa≥0.60 in all items; intraclass correlation coefficient =0.91).
CONCLUSION
Diabetes-21, a short form instrument, was considered valid, reliable and interpretable for assessing health-related quality of life among people with diabetes mellitus.
目的
分析评估糖尿病患者健康相关生活质量的简短量表工具的有效性、信度和可解释性。
方法
这是一项验证性研究，包括糖尿病-39 量表（由 5 个领域和 39 个项目组成）的改编阶段、预测试、结构有效性分析（探索性和验证性）、信度、同时效度和可解释性。
结果
简短最终版本的因子结构与原始工具不同。项目数从 39 项减少到 21 项，领域数从 5 个减少到 4 个。在探索性和验证性分析中，因子负荷分别在 0.41 到 0.90 之间和 0.51 到 0.89 之间。信度良好（克朗巴赫 α=0.91；所有项目的 Kappa 值均≥0.60；组内相关系数=0.91）。
结论
糖尿病-21 是一种简短的量表工具，被认为在评估糖尿病患者的健康相关生活质量方面具有有效性、信度和可解释性。
