Few studies have investigated the psychometric property of new instruments developed locally to assess students' library experience, such as their behavior, perception and attitude toward library use. Validating a survey instrument is critical because using untested assessment instruments is more likely to lead to a lack of credibility in the results, as well as a lack of accuracy in the study's purpose (Sullivan, 2011). This study used data from a locally developed student library experience survey distributed in Spring 2018 at a large public research university library to examine undergraduate and graduate students' behaviors, attitudes and perceptions of library use. To test the validity of the survey as to whether six subdomains of the library experience survey contributed to a single construct, library experience, the study used Rasch model framework. This study contributes to the field as a first example using the Rasch model for library assessment purposes. Suggestions for best practices are discussed.

很少有研究调查本地开发的新工具的心理测量特性，以评估学生的图书馆经验，例如他们的行为，看法和对图书馆使用的态度。验证调查工具至关重要，因为使用未经测试的评估工具更可能导致结果缺乏可信度，以及研究目的缺乏准确性（Sullivan，2011年）。这项研究使用了来自当地开发的学生图书馆体验调查的数据，该调查于2018年春季在大型公共研究型大学图书馆分发，以检查本科生和研究生对图书馆使用的行为，态度和看法。为了检验调查的有效性，以了解图书馆体验调查的六个子域是否构成了一个单一的结构，图书馆体验，该研究使用了Rasch模型框架。这项研究作为使用图书馆评估目的的Rasch模型的第一个示例，为该领域做出了贡献。讨论了最佳做法的建议。
