Providing high-quality diabetes care in nursing homes and home-based care facilities requires suitable instruments to evaluate the level of diabetes knowledge among the health-care providers. Thus, the aim of this study was to examine the psychometric properties of the Michigan Diabetes Knowledge Test adapted for use among nursing personnel.
The study included 127 nursing personnel (32 registered nurses, 69 nursing aides and 26 nursing assistants) at three nursing homes and one home-based care facility in Norway. We examined the reliability and content and construct validity of the Michigan Diabetes Knowledge Test.
The items in both the general diabetes subscale and the insulin-use subscale were considered relevant and appropriate. The instrument showed satisfactory properties for distinguishing between groups. Item response theory-based measurements and item information curves indicate maximum information at average or lower knowledge scores. Internal consistency and the item-total correlations were quite weak, indicating that the Michigan Diabetes Knowledge Test measures a set of items related to various relevant knowledge topics but not necessarily related to each other.
The Michigan Diabetes Knowledge Test measures a broad range of topics relevant to diabetes care. It is an appropriate instrument for identifying individual and distinct needs for diabetes education among nursing personnel. The knowledge gaps identified by the Michigan Diabetes Knowledge Test could also provide useful input for the content of educational activities. However, some revision of the test should be considered.
在养老院和居家护理机构提供高质量的糖尿病护理需要合适的工具来评估医护人员的糖尿病知识水平。因此，本研究的目的是检验适用于护理人员的密歇根糖尿病知识测试的心理测量特性。
该研究纳入了挪威三家养老院和一家居家护理机构的127名护理人员（32名注册护士、69名护理助理和26名护工）。我们检验了密歇根糖尿病知识测试的信度、内容效度和结构效度。
一般糖尿病分量表和胰岛素使用分量表中的题目都被认为是相关且恰当的。该工具在区分不同组方面表现出令人满意的特性。基于项目反应理论的测量和项目信息曲线表明，在平均或较低知识分数水平上有最大信息量。内部一致性和项目与总分的相关性相当弱，这表明密歇根糖尿病知识测试测量的是一组与各种相关知识主题相关的题目，但这些题目不一定相互关联。
密歇根糖尿病知识测试涵盖了与糖尿病护理相关的广泛主题。它是识别护理人员中个体和独特的糖尿病教育需求的合适工具。密歇根糖尿病知识测试所发现的知识差距也可为教育活动的内容提供有用的参考。然而，应考虑对该测试进行一些修订。
