The epidemiology data and global burden of diabetic foot disease underscores the need for effective prevention strategies, which requires an early diagnosis. Patient-reported outcome measures are instruments based on a simple format, which favours their application. Currently, there is an absence of instruments with a broad enough scope to capture the diverse aspects involved in diabetic foot disease.
To develop a questionnaire for the assessment of patients with diabetic foot disease and carry out an analysis of its validity and reliability.
The study was developed in two stages. Stage 1: the Delphi Panel was composed of 22 experts. The questionnaire is made up of 25 questions selected, after three rounds, from an initial sample of 68 questions. Stage 2: A validation study was performed. With a sample of 273 subjects, an exploratory factor analysis and an analysis of internal consistency, items response, and validity were carried out using the Diabetes Quality of Life, SF-12v2, Foot Function Index and EuroQol EQ5D questionnaires. Measurements of error and sensitivity to change were also analyzed.
A 25-item questionnaire (DiaFootQ) was developed. It comprised two dimensions: 1) lifestyle and function; and 2) footwear and foot self-care. Sample (n=273) mean age was 69.77 years (±11.08). The internal consistency of DiafootQ was α=0.916, and item response values were ICC=0.862-0.998. External validity correlation levels ranged from r=0.386 to r=0.888.
DiaFootQ was developed. Integrating the main aspects involved in diabetic foot disease could help to detect more accurately the risk or severity of these patients. DiaFootQ is a well-structured, valid, and reliable tool whose use should be promoted in clinical and research settings.
糖尿病足病的流行病学数据和全球负担突出表明需要有效的预防策略，这需要早期诊断。患者报告的结局测量工具是基于简单格式的工具，有利于其应用。目前，缺乏能够广泛涵盖糖尿病足病所涉及的各种方面的工具。
开发一种用于评估糖尿病足病患者的问卷，并对其有效性和可靠性进行分析。
该研究分为两个阶段进行。第 1 阶段：德尔菲小组由 22 名专家组成。该问卷由 25 个问题组成，这些问题是从最初的 68 个问题样本中经过三轮选择出来的。第 2 阶段：进行了验证研究。在 273 名受试者的样本中，使用糖尿病生活质量、SF-12v2、足部功能指数和 EuroQol EQ5D 问卷进行了探索性因子分析和内部一致性、项目反应和有效性分析，并分析了误差和敏感性变化的测量。
开发了一个 25 项的问卷（DiaFootQ）。它由两个维度组成：1）生活方式和功能；2）鞋类和足部自我护理。样本（n=273）的平均年龄为 69.77 岁（±11.08）。DiafootQ 的内部一致性为α=0.916，项目反应值的 ICC 为 0.862-0.998。外部有效性相关水平范围为 r=0.386 至 r=0.888。
开发了 DiaFootQ。整合糖尿病足病所涉及的主要方面，可以帮助更准确地检测这些患者的风险或严重程度。DiaFootQ 是一种结构良好、有效且可靠的工具，应在临床和研究环境中推广使用。
