Validated instruments collecting data on health-related resource use are lacking, but required, for example, to investigate predictors of healthcare use or for health economic evaluation.The objective of the study was to develop, test and refine a questionnaire collecting data on health-related resource use and expenditure in patients with diabetes.
The questionnaire was tested in 43 patients with diabetes mellitus types 1 and 2 in Germany. Response behaviour suggestive of problems with questions (item non-response, request for clarification, comments, inadequate answer, "don't know") was systematically registered. Cognitive interviews focusing on information retrieval and comprehension problems were carried out.
Many participants had difficulties answering questions pertaining to frequency of visits to the general practitioner (26%), time spent receiving healthcare services (39%), regular medication currently taken (35%) and out of pocket expenditure on medication (42%). These difficulties seem to result mainly from poor memory. A number of comprehension problems were established and relevant questions were revised accordingly.
The questionnaire on health-related resource use and expenditure for use in diabetes research in Germany was developed and refined after careful testing. Ideally, the questionnaire should be externally validated for different modes of administration and recall periods within a variety of populations.
缺乏针对健康相关资源使用情况进行数据收集的经过验证的工具，但这是必需的，例如，用于调查医疗保健使用的预测因素或进行健康经济评估。本研究的目的是开发、测试和完善一种收集糖尿病患者健康相关资源使用和支出数据的问卷。
该问卷在德国 43 名 1 型和 2 型糖尿病患者中进行了测试。系统记录了对问题（项目无应答、澄清请求、评论、不充分的回答、“不知道”）的反应行为，提示可能存在问题。进行了重点关注信息检索和理解问题的认知访谈。
许多参与者在回答有关就诊频率（26%）、接受医疗服务时间（39%）、目前常规用药（35%）和自付药物费用（42%）的问题时遇到困难。这些困难似乎主要源于记忆力不佳。确定了一些理解问题，并相应地修改了相关问题。
经过仔细测试，开发并完善了用于德国糖尿病研究的健康相关资源使用和支出问卷。理想情况下，应在不同人群中针对不同的管理模式和回忆期对外在验证该问卷。
