Background and Purpose. In this paper, we present a protocol for advanced psychometric assessments of surveys based on the Standards for Educational and Psychological Testing. We use the Alberta Context Tool (ACT) as an exemplar survey to which this protocol can be applied. Methods. Data mapping, acceptability, reliability, and validity are addressed. Acceptability is assessed with missing data frequencies and the time required to complete the survey. Reliability is assessed with internal consistency coefficients and information functions. A unitary approach to validity consisting of accumulating evidence based on instrument content, response processes, internal structure, and relations to other variables is taken. We also address assessing performance of survey data when aggregated to higher levels (e.g., nursing unit). Discussion. In this paper we present a protocol for advanced psychometric assessment of survey data using the Alberta Context Tool (ACT) as an exemplar survey; application of the protocol to the ACT survey is underway. Psychometric assessment of any survey is essential to obtaining reliable and valid research findings. This protocol can be adapted for use with any nursing survey.
背景与目的。在本文中，我们提出了一项基于《教育和心理测验标准》对调查问卷进行高级心理测量评估的方案。我们使用艾伯塔情境工具（ACT）作为可应用此方案的示例调查问卷。方法。涉及数据映射、可接受性、信度和效度。可接受性通过缺失数据频率和完成调查问卷所需时间来评估。信度通过内部一致性系数和信息函数来评估。采用一种统一的效度方法，即基于工具内容、应答过程、内部结构以及与其他变量的关系积累证据。我们还探讨了将调查数据汇总到更高层次（如护理单元）时对其性能的评估。讨论。在本文中，我们提出了一项以艾伯塔情境工具（ACT）为例对调查数据进行高级心理测量评估的方案；该方案在ACT调查问卷中的应用正在进行。对任何调查问卷进行心理测量评估对于获得可靠且有效的研究结果至关重要。此方案可适用于任何护理调查问卷。
