Abstract

Aims: To assess and compare the psychometric properties and acceptability of four diabetes-specific quality of life (QoL) scales among adults with Type 2 diabetes (T2D).

Methods: Adults (≥18 years) with T2D living in the United Kingdom (n = 1465) or Australia (n = 248) completed a cross-sectional, online survey including the following: ADDQoL, DCP, DIDP and Diabetes QoL-Q (presented in randomised order), followed by rating scales to assess clarity, relevance, ease of completion, length and comprehensiveness of each scale. Demographic, clinical and psychosocial characteristics were collected. Acceptability (scale completeness and user ratings), response patterns, structure (exploratory and confirmatory factor analyses) and validity (convergent, confirmatory, divergent and known-groups) were examined. Data were analysed by country to assess cross-country reproducibility.

Results: High completion rates (≥89%) and positive user ratings were observed across scales indicating broad acceptability. The DIDP was the strongest performing scale: highest completion rate (97%), user ratings (≥84% positive) and most satisfactory psychometric properties (highest variance explained, consistent factor loadings >0.5 on all items and most permissible model fit parameters). Scale-level floor effects may suggest domain omissions for the brief DIDP.

Conclusions: The current study provides novel insights into the acceptability, validity and reliability of diabetes-specific QoL measures for adults with T2D. Consistent with the published Type 1 diabetes cohort findings, the DIDP is recommended as a brief, acceptable and psychometrically sound measure. However, selection needs to be considered in the context of the specific research or clinical aims and further evidence (e.g. responsiveness) may be required before it can be recommended for use in trials or prospective studies.

评估 2 型糖尿病对生活质量影响的四个量表的可接受性和心理测量特性--"YourSAY：生活质量 "的结果。

目的：评估和比较四种糖尿病生活质量量表在 2 型糖尿病（T2D）成人患者中的心理测量特性和可接受性：居住在英国（n = 1465）或澳大利亚（n = 248）的成人（≥18 岁）2 型糖尿病患者完成了一项横断面在线调查，包括以下内容：调查内容包括：ADDQoL、DCP、DIDP 和 Diabetes QoL-Q（按随机顺序排列），然后对每个量表的清晰度、相关性、完成难易程度、长度和全面性进行评分。此外，还收集了人口、临床和社会心理特征。对可接受性（量表完整性和用户评分）、反应模式、结构（探索性和确认性因素分析）和有效性（收敛性、确认性、发散性和已知组）进行了研究。数据按国家进行分析，以评估跨国再现性：所有量表的完成率都很高（≥89%），用户评价也很好，这表明量表具有广泛的可接受性。DIDP 是表现最出色的量表：完成率最高（97%），用户评分最高（≥84%），心理测量特性最令人满意（解释的方差最大，所有项目的因子载荷一致>0.5，模型拟合参数最高）。量表层面的底限效应可能表明简明 DIDP 存在领域遗漏：目前的研究为糖尿病成人 QoL 测量的可接受性、有效性和可靠性提供了新的见解。与已发表的 1 型糖尿病队列研究结果一致，建议将 DIDP 作为一种简短、可接受且心理计量学上可靠的测量方法。不过，在选择时需要考虑具体的研究或临床目的，在推荐用于试验或前瞻性研究之前，可能还需要进一步的证据（如反应性）。

期刊介绍： Diabetic Medicine, the official journal of Diabetes UK, is published monthly simultaneously, in print and online editions. The journal publishes a range of key information on all clinical aspects of diabetes mellitus, ranging from human genetic studies through clinical physiology and trials to diabetes epidemiology. We do not publish original animal or cell culture studies unless they are part of a study of clinical diabetes involving humans. Categories of publication include research articles, reviews, editorials, commentaries, and correspondence. All material is peer-reviewed. We aim to disseminate knowledge about diabetes research with the goal of improving the management of people with diabetes. The journal therefore seeks to provide a forum for the exchange of ideas between clinicians and researchers worldwide. Topics covered are of importance to all healthcare professionals working with people with diabetes, whether in primary care or specialist services. Surplus generated from the sale of Diabetic Medicine is used by Diabetes UK to know diabetes better and fight diabetes more effectively on behalf of all people affected by and at risk of diabetes as well as their families and carers.”
