Abstract： ［Purpose/significance］This dissertation analyzed the 392 articles published in eight SSCI journals of library science in 2022, summarized the hot topics and frontier topics, so as to provide reference for in-depth research and work practice in the library. ［Method/process］By using the content analysis method, this dissertation systematically reviewed the articles published in 2022 in the following eight journals: Journal of Documentation, College & Research Libraries, Library & Information Science Research, Journal of Librarianship and Information Science, Library Trends, The Library Quarterly, International Journal of Libraries and Information Studies, and The Journal of Academic Librarianship, from the aspects of research theme and content.［Result/conclusion］The analysis results showed that foreign library science research in 2022 covered ten topics: information behavior and user research, library management, library service, the basic theory of library and information science, subject education and teaching, information literacy, information processing and knowledge management, information measurement and information analysis, information ethics, and digital humanities; the research topics include information behavior and user research, library management and library service, and the frontier focused on two research topics of digital humanities and the basic theory of library and information science development. Taking this as a revelation, the future library science should take strengthening the library responsibility as the research content, and focus on the minority and weak reader groups.

Abstract： The change point analysis (CPA), as one of the most widely used methods for statistical process control, is introduced to psychological and educational measurement for detection of aberrant response patterns in recent years. CPA outperforms the traditional method as follows: In addition to detecting aberrant response patterns, it can also pinpoint the locations of change points, contributing to efficient cleansing of response data. The method is employed to determine whether there is a point so that the complete sequence can be divided into two parts with different statistical properties, where person-fit statistics (PFS) is needed for quantifying the difference between two sub-sequences. Future researchers should pay more attention to multiple change points detection, making full use of other effective information like response time data, developing non-parametric indices as well as reforming the exiting person-fit statistics for polytomous and multidimensional tests, so as to enhance its applicability and power.

Abstract：变点分析法(change point analysis, CPA)近些年才引入心理与教育测量学，相较于传统方法，CPA不仅可以侦查异常作答被试，还能自动精确地定位变点位置，高效清洗作答数据。其原理在于：判断作答序列中是否存在可将该序列划分为具有不同统计学属性两部分的点(即变点)，并且需使用被试拟合统计量(person-fit statistic, PFS)来量化两个子序列之间的差异。未来可将单变点分析拓展至多变点，结合反应时等信息，构建非参数化指标以及将现有指标拓展至多级计分或多维测验，以提高CPA的适用广度及效力。
