Abstract

Background: Critical care nurses who care for postoperative cardiac surgery patients need such specialty knowledge as atrial electrograms (AEGs). An inadequate audit trail exists for psychometric performance of instruments to measure knowledge of AEGs.

Objectives: The aim of this study was to revise a previously tested instrument and assess evidence for content validity (content validity index), internal consistency (Cronbach α), and stability (correlation coefficient, r) reliability against the a priori criterion of 0.80.

Methods: The multiple-choice response, self-administered, paper-and-pencil instrument was revised to 20 items and named the Drake Atrial Electrogram Assessment Survey (DAEGAS). A panel of 6 AEG experts reviewed the DAEGAS for content validity evidence. The instrument was further revised to 19 items (13 knowledge and 6 AEG interpretation) and tested with 76 critical care nurses from the greater Houston metropolitan area.

Results: The content validity index was 0.93. Cronbach α was .51, and test-retest r was 0.74. Cronbach α increased to .60 and r was 0.73 with removal of 3 items: 2 items with a negative item-total correlation and 1 item that was transitioned to a sample question.

Discussion: Content validity evidence exceeded the a priori criterion. Internal consistency and stability reliability estimates did not meet the criterion, albeit the latter met the criterion recommended by psychometricians for a new instrument. Recommendations include further development of the DAEGAS to improve internal consistency estimates and testing for evidence of other forms of validity. Reliable and valid assessment of critical care nurse knowledge of AEGs will require improved psychometric performance of the DAEGAS.

德雷克心房电图评估调查的发展及初步心理测量学检验。

背景:护理心脏手术术后患者的重症监护护士需要心房电图(aeg)等专业知识。对于测量aeg知识的工具的心理测量性能存在不充分的审计跟踪。目的:本研究的目的是修订先前测试的工具，并评估内容效度(内容效度指数)、内部一致性(Cronbach α)和稳定性(相关系数r)的证据，以0.80的先验标准为信度。方法:将选择题、自填、纸笔量表修改为20项，命名为德雷克心房电图评估量表(DAEGAS)。一个由6名AEG专家组成的小组审查了DAEGAS的内容有效性证据。该工具进一步修订为19项(13项知识和6项AEG解释)，并对来自大休斯顿市区的76名重症监护护士进行了测试。结果:内容效度指数为0.93。Cronbach α为0.51，重测r为0.74。Cronbach α增加到0.60,r为0.73，去除3个项目:2个项目与项目总数负相关，1个项目转换为样本问题。讨论:内容效度证据超出先验标准。内部一致性和稳定性可靠性估计不符合标准，尽管后者符合心理测量学家为新工具推荐的标准。建议包括进一步发展DAEGAS，以改进内部一致性估计和检验其他形式的有效性证据。可靠和有效的评估危重病护理护士的aeg知识将需要改进DAEGAS的心理测量性能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
