Mokken Scale Analysis for Dichotomous Items Using Marginal Models

Scalability coefficients play an important role in Mokken scale analysis. For a set of items, scalability coefficients have been defined for each pair of items, for each individual item, and for the entire scale. Hypothesis testing with respect to these scalability coefficients has not been fully developed. This study introduces marginal modelling as a framework to derive the standard errors for the scaling coefficients and test hypotheses about these coefficients. Several examples demonstrate the possibilities of marginal modelling in Mokken scale analysis. These possibilities include testing whether Mokken’s criteria for a scale are satisfied, testing whether scalability coefficients of different items are equal, and testing whether scalability coefficients are equal across different groups.     

锚定判断中的心理刻度效应：来自ERP的证据

当前主要有两种理论解释锚定效应的发生机制：锚定调整启发模型和选择通达模型。同样,锚值可能是自发产生的,也可能是外部提供的。本研究用两个ERP实验分别探讨了不同精细程度的心理刻度对自发锚定加工和外部锚定加工的影响。结果表明,只有在自发锚引起的锚定加工中才出现心理刻度效应：在目标呈现后250~800ms之间,精细心理刻度比粗糙心理刻度诱发一个更大的波形正走向,支持锚定调整启发模型。在外部锚引起的锚定加工中,没有出现心理刻度效应,却出现了一个与通达有关的N300成分,支持选择通达加工模型。总的结果支持了锚定加工的双重属性：锚定判断是主动调整还是选择通达取决于不同的情境

结合现代航线驾驶工作特性及CRM和TEM模型基础上, 通过文献分析、专家访谈和开放式问卷调查, 筛选出现代航线飞行员驾驶安全所必备的27种关键行为特征, 构成中国文化背景下航线驾驶安全行为评价量表的检测项目。对118名中国航线飞行员测评数据的验证性因素分析表明, 由自动化系统认识、领导和管理、情境意识与决策、人际交流与合作技能组成的四维模型优于其他假设模型, 且在四个飞行阶段中均具有良好的信度和结构效度。以其中86名飞行员的安全绩效考核(安全规章、飞行作风、飞行技能和机组管理)数据和飞行员在每个飞行阶段的驾驶安全行为总体表现为效标变量, 以航线驾驶安全行为评价量表四个维度上的驾驶行为特征为预测变量分别进行层次回归分析, 结果表明: 航线驾驶安全行为多维评价量表具有良好的预测效度; 四个维度变量对维护不同飞行阶段的驾驶安全行为分别具有显著的贡献性, 且这种贡献性因飞行阶段的任务不同而有所差异。航线安全驾驶行为多维评价量表的构建, 不仅为航线飞行员安全驾驶行为规范性评估、机组驾驶行为问题诊断以及安全绩效考核提供了一套客观有效的评价工具, 而且也为有针对性的设计航线飞行员选拔模式和有效实施机组人员非技术性技能/CRM训练提供了一个良好的理论基础。     

ALTRUISM IN SUICIDE TERROR ORGANIZATIONS

In recent years, much has been learned about the strategic and organizational contexts of suicide attacks. However, motivations of the agents who commit them remain difficult to explain. In part this is because standard models of social learning as well as Durkheimian notions of sacrificial behavior are inadequate in the face of the actions of human bombers. In addition, the importance of organizational structures and practices in reinforcing commitment on the part of suicide recruits is an under-explored factor in many analyses. This essay examines the potential applicability of evolutionary models of altruism to the understanding of commitment to suicide on the part of terrorist organizational recruits. Three evolutionary models of sacrificial behavior in nonhuman species and many categories of human behavior are explored cross-organizationally: reciprocity, inclusive fitness theory, and induced altruism. Reciprocal altruism is unlikely to be a major motivator in suicide attacks because the costs exhibited by attackers are too high to be adequately compensated. However, the role of evolved self-deception in perceptions of personal death, and thus of rewards in the afterlife, is potentially illuminating. Inclusive fitness theory can help explain the motivations of attackers because rewards to kin often are offered by organizations to suicide recruits. However, suicide bombers also often act out of revenge for the loss of or injury to relatives, and inclusive fitness theory generally, as well as more specific theoretical models of retaliatory aggression, may not adequately account for the bombers' actions. Predictions from induced altruism theory appear to be well supported because suicide terror organizations tend to be tightly structured around practices intended to maintain and reinforce commitment though the manipulation of kinship-recognition cues.     

高中生不同类型的沉思对抑郁症状发展的中介作用

探讨不同类型的沉思对抑郁症状变化的中介作用及性别差异。用流调中心用抑郁量表和沉思反应量表等自评量表对512名高中生追踪调查3个月,用层次回归法分析数据。结果表明：（1）男、女生的抑郁情绪、强迫性冥思和反思不存在差异。（2）强迫性冥思对抑郁症状的变化起部分中介作用;反思与第二次抑郁症状不相关,不存在中介作用。（3）女生的强迫性冥思对抑郁症状的变化起部分中介作用;男生的强迫性冥思对抑郁症状变化不存在中介作用。结论不同类型的沉思对抑郁症状变化的中介作用是不同的,并且存在性别差异。     

沉思和分心对负情绪和自传体记忆的影响

探讨在诱发了抑郁、焦虑、悲伤等负性情绪后,沉思和分心对正常成人的情绪主观报告、生理变化和自传体记忆的作用。64名被试被随机分为两组,用故事和电影短片分别诱发了负性和中性（控制组）两种情绪状态。然后进行随机分组,分别进行分心和沉思的反应任务。测量四组被试的情绪主观报告、生理变化以及多种形式和性质的自传体记忆。结果表明：（1）沉思和分心对这些负情绪的调节作用不显著;（2）沉思引起更多的负性记忆,正性复合指数更小,自传体记忆的具体性更弱。结论：沉思导致更多负性记忆,维持了概括性记忆,更有可能加重已经激活的负情绪     

Measuring General Indecisiveness

Although indecisiveness seems to be a widespread problem, little empirical research has addressed its measurement. Frost and Shows (1993; Behaviour Research and Therapy, 31, 683–692) introduced the Indecisiveness Scale (IS) as a measure of individual differences in general indecisiveness. Although these authors conducted various psychometric analyses, some properties (e.g., factor structure, test-retest reliability) were not investigated. In the present studies, several reliability and validity indices were computed. First, four of the fifteen items of the IS were found to be omissible. Second, 4-week test-retest reliability was found to be satisfactory. Third, scores on the IS were found to correlate meaningfully with a concurrent measure of decision making, and with various scales of psychopathology. Lastly, in Study 4, the IS was found to predict scores on a behavioural measure of decision making, suggesting good predictive validity. Overall, these findings suggest that the IS has good psychometric properties.     

Aboriginal language knowledge and youth suicide

This brief report details a preliminary investigation into how community-level variability in knowledge of Aboriginal languages relate to “band”-level measures of youth suicide. In Canada, and, more specifically, in the province of British Columbia (BC), Aboriginal youth suicide rates vary substantially from one community to another. The results reported demonstrate that not only did this simple language-use indicator prove to have predictive power over and above that of six other cultural continuity factors identified in previous research, but also that youth suicide rates effectively dropped to zero in those few communities in which at least half the band members reported a conversational knowledge of their own “Native” language.     

Suicidal Thinking and Perfectionism: The Role of Goal Adjustment and Behavioral Inhibition/Activation Systems (BIS/BAS)

The current study investigated the associations among perfectionism, goal adjustment, behavioral activation sensitivity (BAS), behavioral inhibition sensitivity (BIS), and suicidal thinking. Participants (n = 255) completed the Multidimensional Perfectionism Scale, the BIS/BAS scale, the Goal Adjustment scale, and a measure of suicidal thinking. The findings showed that socially prescribed perfectionism was the only perfectionism dimension associated with suicidal thinking. Goal reengagement (but not goal disengagement) is an important construct in the suicidal process. A series of hierarchical regression analyses showed that goal reengagement moderates and mediates the effect of socially prescribed perfectionism on suicidal thinking. BIS was also associated with suicidal behavior but its effect was mediated via socially prescribed perfectionism. The theoretical and treatment implications of the relationships between socially prescribed perfectionism, goal reengagement, and suicidal thinking and between BIS, socially prescribed perfectionism, and suicidal thinking are discussed. Future research is required to determine whether these relationships are predictive of suicidal thinking and behavior over time.     

人格测验中作假的控制方法

被试很容易对人格测验作假,这严重影响了人格测验的有效性。目前测评专家已经提出了一些应对作假的方法,它们可被分为事前控制技术和事后识别技术两大类。前者包括迫选式量表,警告及假渠道技术等,后者包括作假识别量表,IRT及反应时识别技术等。目前,在人格测验中嵌套使用作假识别量表,以及在测验指导语中加入警告是比较有效的两种方法,迫选式量表的发展也值得期待。由于研究者对作假的内部发生机制了解较少,这制约了IRT与反应时识别技术的发展。
