This study aims to analyse the psychometric properties of the most recent 19 item version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) in a large, population-based sample of adults living in Australia.
A total of 3,951 people living with diabetes completed the ADDQoL as part of the Living With Diabetes Study. Data analysis investigated the feasibility of using the ADDQoL in a large, population-based survey; internal consistency; adherence to a single-factor structure; and convergent/discriminant validity.
Data support the feasibility of using the ADDQoL in population-based survey research. Although a strict single-factor structure for the ADDQoL was not demonstrated, the results overall support an interpretation of essential unidimensionality. A validation matrix provides support for the convergent and divergent validity of the measure, as does the ADDQoL's ability to discriminate between respondents based on insulin dependence and complications.
The ADDQoL has good psychometric properties and provides clinicians and researchers with a useful tool for comprehensively assessing quality of life in adults with diabetes.
本研究旨在分析最新的 19 项糖尿病依赖生活质量评估量表（ADDQoL）在澳大利亚一个大型基于人群的成年糖尿病患者样本中的心理测量特性。
共有 3951 名患有糖尿病的人完成了 ADDQoL 量表作为“糖尿病生活研究”的一部分。数据分析调查了在大型基于人群的调查中使用 ADDQoL 的可行性；内部一致性；对单因素结构的遵守；以及收敛/判别效度。
数据支持在基于人群的调查研究中使用 ADDQoL 的可行性。尽管 ADDQoL 没有严格的单因素结构，但结果总体上支持基本的单维性解释。验证矩阵为该测量的收敛和判别效度提供了支持，ADDQoL 区分基于胰岛素依赖和并发症的受访者的能力也是如此。
ADDQoL 具有良好的心理测量特性，为临床医生和研究人员提供了一种有用的工具，可全面评估成年糖尿病患者的生活质量。
