追踪研究中测验信度的估计

追踪研究中测验工具的信度是衡量追踪研究质量的重要指标。传统的信度估计方法不适用于估计追踪研究的测验信度。近年来, 研究者提出了四种估计追踪研究的测验信度, 包括估计单个时间点的测验信度系数rw和r(Sw), 以及估计整个追踪研究的测验信度系数RT和RL。本文评述了这四种信度估计方法的数学模型、前提假设及其优缺点。RT和RL既可估计追踪研究中单个时间点的测验信度, 也可估计追踪研究中整个追踪研究的测验信度, 所需要的前提假设较少, 推荐同时使用RT和RL来估计追踪研究的测验信度。     

两水平研究中单维测验信度的估计

在心理、教育和管理等研究领域中,经常会碰到两水平（两层）的数据结构,如学生嵌套在班级中,员工嵌套在企业中。在两水平研究中,被试通常不是独立的,如果直接用单水平信度公式进行估计,会高估测验信度。文献上已有研究讨论如何更准确地估计两水平研究中单维测验的信度。本研究指出了现有的估计公式的不足之处,用两水平验证性因子分析推导出一个新的信度公式,举例演示如何计算,并给出简单的计算程序。     

单维测验合成信度元分析

元分析是根据现有研究对感兴趣的主题得出比较准确和有代表性结论的一种重要方法,在心理、教育、管理、医学等社会科学研究中得到广泛应用。信度是衡量测验质量的重要指标,用合成信度能比较准确的估计测验信度。未见有文献提供合成信度元分析方法。本研究在比较对参数进行元分析的三种模型优劣的基础上,在变化系数模型下推出合成信度元分析点估计及区间估计的方法;以区间覆盖率为衡量指标,模拟研究表明本研究提出的合成信度元分析区间估计的方法得当;举例说明如何对单维测验的合成信度进行元分析。     

项目表述效应对人格测验信度和效标效度的影响——以核心自我评价量表(CSES)为例

项目表述效应是指由项目表述方式的差异引起的与测量内容无关的系统变异,项目表述效应模型的统计本质是一种双因子模型。本研究以核心自我评价量表(CSES)为例,探讨项目表述效应对人格测验信效度的影响。采用核心自我评价量表、生活满意度量表和积极情感消极情感量表对340名“蚁族”进行测查。结果表明,CSES在核心自我评价特质以外,还存在一个反向题项目表述效应因子;忽视项目表述效应对CSES的同质性信度和效标关联效度有重要影响：高估CSES的同质性信度,低估核心自我评价与生活满意度、积极情感的正相关,高估核心自我评价与消极情感的负相关。     

中国创伤后应激反应量表在大学生群体中的应用

采用以中国文化为背景编制的“中国自然灾难幸存者创伤后应激反应量表(CPI)”, 对芦山地震灾区某大学1057名学生进行测试, 考察CPI在地震后大学生人群的应用, 并探讨PTSD的影响因素。结果发现, 性别、主观害怕体验和D型人格等因素能够预测PTSD症状的发生。CPI在地震受灾的大学生群体中具有良好的信效度, 可用于PTSD症状严重程度的评估。     

Neural substrates of cognitive skill learning in Parkinson's disease

While cognitive skill learning is normally acquired implicitly through frontostriatal circuitry in healthy individuals, neuroimaging studies suggest that patients with Parkinson's disease (PD) do so by activating alternate, intact brain areas associated with explicit memory processing. To further test this hypothesis, 10 patients with PD and 12 healthy controls were tested on a modified, learning version of the Tower of London task while undergoing positron emission tomography at four different time points over the course of learning. Despite having less accurate problem solving abilities than controls, PD patients were able to acquire the skill learning task. However, as compared to controls, they maintained higher levels of cerebral blood flow activity in the dorsolateral prefrontal cortex and hippocampus and showed an increase in activity in the frontopolar cortex and posterior cingulate over the course of learning. These findings reflect a shift to the explicit memory system in PD patients, enabling them to learn this cognitive skill, which is normally acquired by control subjects using implicit learning strategies and frontostriatal circuitry.     

Adolescent coping scales: a critical psychometric review

Individual coping is identified as an important factor in relation to health and well-being. Although several coping scales have been developed, key terms of coping such as nature and a number of primary and secondary factors (dimensions) are obscure. Coping scales, such as those that have been developed through exploratory factor analysis (EFA), have been criticized for poor psychometric properties, yet the critique so far does not evaluate development of the scales against best test-theoretical practice. The present study reviews six adolescent coping scales against ten detailed psychometric criteria in relation to statistical choices throughout the process of scale development. All six scales measured poorly on several criteria. Best practice had not been followed throughout their development and they suffered serious psychometric limitations. These findings indicate that there still is empirical research to be pursued in search of latent constructs and possible dimensions of coping through the implementation of EFA.     

BTL—QZ—V1．1气质测试系统的修订

修订BTL-QZ-V1．1气质测试系统。对519名12—21岁男女学生进行了测量。结果发现：神经系统特性具有年龄差异,随年龄增长兴奋性、抑制性增强,灵活性、稳定性增高;12～14岁是其快速增长期,14～18岁为慢速增长期,18岁后为稳定期;神经系统的兴奋性、抑制性具有性别差异,男生强于女生;可将气质类型划分为10种,年龄和性别不影响气质类型的分布;除灵活性外,神经系统兴奋性、抑制性和稳定性的重测信度系数在0．6～0．8之间,且达到显著性水平;以80·8神经类型量表为效标,所得相关系数达中等程度。提示BTL-QZ-V1．1气质测试系统的评定需按年龄和性别分组进行,建立的分组标准较为准确科学,信度、效度较高,可以广泛应用。     

Substantive and procedural norms in normative multiagent systems

Procedural norms are instrumental norms addressed to agents playing a role in the normative system, for example to motivate these role playing agents to recognize violations or to apply sanctions. Procedural norms have first been discussed in law, where they address legal practitioners such as legislators, lawyers and policemen, but they are discussed now too in normative multiagent systems to motivate software agents. Procedural norms aim to achieve the social order specified using regulative norms like obligations and permissions, and constitutive norms like counts-as obligations. In this paper we formalize procedural, regulative and constitutive norms using input/output logic enriched with an agent ontology and an abstraction hierarchy. We show how our formalization explains Castelfranchi's notion of mutual empowerment, stating that not only the agents playing a role in a normative system are empowered by the normative system, but the normative system itself is also empowered by the agents playing a role in it. In our terminology, the agents are not only institutionally empowered, but they are also delegated normative goals from the system. Together, institutional empowerment and normative goal delegation constitute a mechanism which we call delegation of power, where agents acting on behalf of the normative system become in charge of recognizing which institutional facts follow from brute facts.
