Examination of the Japanese version of the Fear of COVID-19 Scale among Adults Using Classical Test Theory and Item Response Theory1, 2

Globally, the COVID-19 pandemic has impaired every aspect of life, especially causing much psychological damage—for instance, increasing the risk of suicide. Intense fear and anxiety are considered to play a central role in mental health problems. This study examined the psychological properties of the Japanese version of the Fear of COVID-19 Scale (FCV-19S) using classical test theory (CTT) and item response theory (IRT). Five hundred fifty participants aged 18–69 years and from across Japan completed questionnaires, including the Japanese FCV-19S, the Japanese Depression Anxiety Stress Scales-15 (DASS-15), and the Japanese version of the Kessler 6 (K6). CTT showed that each item of the Japanese FCV-19S had no ceiling and floor effect and was close to the normal distribution, and IRT revealed that each item had an appropriate parameter of discrimination and difficulty. Finally, the Japanese FCV-19S was shown to have an acceptable reliability and moderate good concurrent validity. Consequently, the Japanese FCV-19S has robust psychometric properties and can be useful for early detection of adults impacted by the COVID-19 pandemic.     

Covariance structure analysis in several populations

This paper is concerned with the study of covariance structural models in several populations. Estimation theory of the parameters that are subject to general functional restraints is developed based on the generalized least squares approach. Asymptotic properties of the constrained estimator are studied; and asymptotic chi-square tests are presented to evaluate appropriate model comparisons. The method of multipliers and the standard reparametrization technique are discussed in obtaining the estimates. The methodology is demonstrated by a set of real data.Computer facilities were provided by the Computer Services Center, The Chinese University of Hong Kong. The authors are indebted to several anonymous reviewers for suggestions for improvement of this paper.     

过去时间的心理结构

４０８名大学生被试用秒、分、小时、日、星期、年和月７个时间单位和模糊统计试验方法对４０个不定的过去时间修饰词作经验赋值,结果显示：（１）过去时间和未来时间在心理结构上是对称的,分为三个心理时间段,即以秒和分为计时单位的“较近的过去”和“较近的未来”,以小时、日和月为计时单位的“近的过去”和“近的未来”,和以年为计时单位的“远的过去”和“远的未来”。（２）随着时间修饰词的词义离现在由近至远,其词义地     

药物性肝损伤的诊断思维

药物性肝损伤（DILI）是指由于药物或其代谢产物引起的肝脏损害。DILI的诊断尚无金标准,目前国际上比较常用的诊断标准分别从数个不同方面各自进行量化评分,根据得分情况做出诊断。本文归纳DILI的产生机制、诊断标准、临床分型及病理类型,总结推论其临床诊断思维与决策,以供临床医生参考,提高诊断水平。     

颈动脉病变的治疗现状

颈动脉病变尤其是颈动脉狭窄治疗上的分歧,颈动脉内膜切除术受欧美学者推崇,颈动脉支架成形技术受国内学者青睐,本文就近年来的文献复习发现颈动脉内膜切除术和颈动脉支架成形术各有相宜的适应证,各有优缺点,根据各自医院的设备条件、医师对颈动脉内膜切除术和颈动脉支架成形术熟悉程度来开展工作,对颈动脉狭窄治疗均有益处,存在的问题和困...     

印象整饰与内隐态度效应

运用内隐联想测验对不同印象整饰水平个体的内隐态度进行了研究。结果表明：不同自我监控者的内隐性态度是存在的,高自我监控者的内隐态度和外显态度存在分离。研究对“印象整饰对强迫服从后态度改变的影响”的结果做出解释：自我监控者强迫服从后的态度中庸是其关注自身的公众形象而有意压抑和控制其内隐性的评价造成的。     

PDP启动型实验程序与Richardson-Klavehn模型的比较研究

2个实验对PDP的启动型实验程序与Richardson-Klavehn的修正模型进行了比较研究,通过对指示语的操纵,考察提取策略是否完全受意志控制,以及注意水平、刺激材料、测验类型、加工水平对被试作业的影响.结果发现刺激材料对有意识控制记忆的实验结果影响很大,对PDP的无意识自动加工参数无影响;启动型实验程序的结果与PDP理论相当一致;提取策略不一定是受意志精确控制的.     

学前儿童的现实性监测:即时和延时测验

考察了4至5岁儿童的现实性监测在延时0天、3天和7天条件下的成绩。结果发现:对真实动作的源混淆更多地发生在延时3-7天,而对想象动作的源混淆更多地发生在0-3天,且对想象动作的现实性监测比对真实动作的现实性监测更早达到随机水平。这表明事件在现实性监测的时间效应中存在不同的特点。     

词汇听觉使用频率在两类记忆测验中的比较研究

讨论了词语使用过程中视觉使用频率和听觉使用频率的区分。通过两个实验对听觉使用频率进行了探讨。实验一通过量表评定法得到了两组视觉使用频率相同,但听觉使用频率不同的双字词,实验二利用实验一得到的两组双字词对被试进行了记忆测验,在单一的听觉条件下,发现在自由回忆,听觉再认和模糊辨听这两类不同的记忆测验中出现了实验性分离现象;反映了听觉使用频率自身的一些特征。
