Timely screening and intervention can prevent the development of the diabetic foot. However, delayed visits to the clinic are common among diabetic foot patients. The study aimed to develop and validate a questionnaire to assess healthcare-seeking behavior among patients with diabetic high-risk foot.
The questionnaire of healthcare-seeking intention for patients with diabetic high-risk foot was developed in two phases: (1) Developing the questionnaire: 1) questionnaire items were formulated after literature review, group discussion and semi-qualitative interview; 2) a two-round modified Delphi method was to examine the content validity and the degree of consistency in questionnaire items; 3) conducting pre-survey to revise the questionnaire items. (2) Assessing the internal reliability and construct validity.
The final questionnaire consisted of five main themes and 28 items with a five-point rating. Cronbach's alpha coefficients for the five dimensions were respectively 0.937 (relevant knowledge of diabetic foot), 0.669 (attitudes toward seeking care), 0.896 (social support for seeking care), 0.621 (efficacy in coping with foot symptoms), 0.871 (intention to seek care). The Scale-level Content Validity Index of the five parts was 1.00, 0.80, 1.00, 1.00, and 1.00, respectively. The Kaiser-Meyer-Olkin values for each dimension was greater than 0.7, and the p-value for Bartlett's test of sphericity was less than 0.05.
This questionnaire showed good validity, internal consistency, and reliability. It provided a potentially useful instrument to evaluate healthcare-seeking intention among patients with diabetic high-risk foot.
及时筛查和干预可预防糖尿病足的发展。然而，糖尿病足患者延迟就诊的情况很常见。本研究旨在开发并验证一份问卷，以评估糖尿病高危足患者的就医行为。
糖尿病高危足患者就医意向问卷分两个阶段制定：（1）问卷编制：1）在文献回顾、小组讨论和半定性访谈后拟定问卷项目；2）采用两轮改良德尔菲法检验问卷项目的内容效度和一致性程度；3）进行预调查以修订问卷项目。（2）评估内部信度和结构效度。
最终问卷包括五个主要主题和28个项目，采用五点评分法。五个维度的克朗巴赫α系数分别为0.937（糖尿病足相关知识）、0.669（就医态度）、0.896（就医社会支持）、0.621（应对足部症状的效能）、0.871（就医意向）。五个部分的量表水平内容效度指数分别为1.00、0.80、1.00、1.00和1.00。各维度的Kaiser-Meyer-Olkin值均大于0.7，Bartlett球形检验的p值小于0.05。
该问卷具有良好的效度、内部一致性和信度。它为评估糖尿病高危足患者的就医意向提供了一种潜在有用的工具。
