Individual,Community, and National Resilience in Peace Time and in the Face of Terror: A Longitudinal Study

The present paper is based on thrice-repeated measures. The sample constituted 561 Jewish Israeli adults who experienced these terror attacks. The study examined individual, community and national resilience and their associations with resilience-promoting factors (sense of coherence, social support, and self-efficacy); as well as resilience-suppressing factors (distress symptoms, sense of danger, and exposure). Results indicated that resilience scores were quite stable across the three repeated measures, whereas sense of coherence, distress symptoms, sense of danger, and exposure significantly changed across the three repeated measures. Sense of coherence was the best predictor for individual, community, and national resilience.     

Longitudinal effects of contact on intergroup relations: The role of majority and minority group membership and intergroup emotions

A field study was conducted in the Italian context to examine the longitudinal effects of contact on improved intergroup relations, and to test whether the effects were different for majority and minority group members. Furthermore, we examined the processes underlying contact effects. Participants were 68 Italian (majority) and 31 immigrant (minority) secondary school students, who completed a questionnaire at two time points. The results of regression analyses showed that, consistent with the contact hypothesis (Allport, 1954 ), quantity and quality of contact longitudinally improved outgroup evaluation and increased the attribution of positive stereotypes to the outgroup; the reverse paths were non‐significant. Notably, whereas quantity of contact improved intergroup attitudes and stereotypes for both majority and minority participants, quality of contact had reliable effects only for the majority group. Intergroup anxiety and empathy mediated the longitudinal effects of quantity of contact for both Italians and immigrants; the cross‐lagged effects of contact quality on criterion variables for the Italian group were mediated by intergroup empathy. The theoretical and practical implications of findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

纵向数据的中介效应分析

目前中介效应检验主要是基于截面数据,但许多时候截面数据的中介分析不适合进行因果推断,因而需要收集历时性的纵向数据,进行纵向数据的中介分析。评介了基于交叉滞后面板模型、多层线性模型和潜变量增长模型的纵向数据的中介分析方法及其四个发展。第一,中介效应随时间变化,如连续时间模型、多层时变系数模型。第二,中介效应随个体变化,如随机效应的交叉滞后面板模型和多层自回归模型。第三,中介模型的整合,如交叉滞后面板模型与多层线性模型整合为多层自回归模型。第四,中介检验方法的发展,建议使用Monte Carlo、Bootstrap和贝叶斯法进行纵向数据的中介分析。总结出一个纵向数据的中介分析流程并给出相应的Mplus程序。随后展望了纵向数据的中介分析的拓展方向。     

Examining Spirituality Over Time: Latent Growth Curve and Individual Growth Curve Analyses

SUMMARY

Research on spirituality and religiousness has gained growing attention in recent years; however, most studies have used cross-sectional designs. As research on this topic evolves, there has been increasing recognition of the need to examine these constructs and their effects through the use of longitudinal designs. Beyond repeated-measures ANOVA and OLS regression models, what tools are available to examine these constructs over time? The purpose of this paper is to provide an overview of two cutting-edge statistical techniques that will facilitate longitudinal investigations of spirituality and religiousness: latent growth curve analysis using structural equation modeling (SEM) and individual growth curve models. The SEM growth curve approach examines change at the group level, with change over time expressed as a single latent growth factor. In contrast, individual growth curve models consider longitudinal change at the level of the person. While similar results may be obtained using either method, researchers may opt for one over the other due to the strengths and weaknesses associated with these methods. Examples of applications of both approaches to longitudinal studies of spirituality and religiousness are presented and discussed, along with design and data considerations when employing these modeling techniques.     

混龄教育对幼儿助人行为的促进作用——来自纵向研究的证据

混龄教育是指将不同年龄阶段和发展水平的幼儿按照一定的模式加以组合,以促进幼儿认知和社会性发展的一种教育方式.为了从实证角度考察混龄教育对幼儿助人行为的影响,本研究采用纵向设计的方法,追踪了40个分别来自混龄教育和同龄教育班级的幼儿.通过设置不同的助人情境,安排不同的受助对象,对比两种教育模式下幼儿的助人行为成绩及前后测成绩的变化.结果发现,幼儿在不同助人情境中的助人行为不存在显著差异;接受过混龄教育的年长幼儿比接受过同龄教育的年长幼儿更倾向于帮助低龄幼儿;混龄教育幼儿后测的助人行为较前测有了显著的提高,同龄教育幼儿的助人行为变化不显著.这表明,混龄教育比同龄教育更能促进幼儿的助人行为发展,这一效应尤其表现在他们对待低龄幼儿的助人行为中.     

Opportunities and Issues in Modeling Intensive Longitudinal Data: Learning from the COGITO Project

Abstract

Technological developments increasingly permit the collection of longitudinal data sets in which the data structure contains a large number of participants N and a large number of measurement occasions T. Promising new dynamical systems approaches to the analysis of large N, large T data sets have been proposed that utilize both between-subjects and within-subjects information. The COGITO project, begun over a decade ago, is an early large N?=?204, large T?=?100 study that collected high quality cognitive and psychosocial data. In this introduction, I describe the COGITO project and conceptual and statistical issues that arise in the analysis of large N, large T data sets. I provide a brief overview of the five papers in the special section which include conceptual pieces, a didactic presentation of a dynamic structural equation approach, and papers reporting new statistical analyses of the COGITO data set to answer substantive questions. Although many challenges remain, these new approaches offer the promise of improving scientific inquiry in the behavioral sciences.

We propose a valid core for the much-disputed thesis that Deliberation Crowds Out Prediction, and identify terminological causes for some of the apparent disputes.     

追踪研究在组织行为学中的应用

追踪研究是一种通过引入时滞, 以探索变量动态变化趋势和变量之间相互关系的调查研究方法。近年来, 在组织行为学中, 追踪研究越来越受到学者们的关注, 追踪研究成果也在逐渐增加, 但是大多数研究者尤其是国内研究者, 对追踪研究尚缺乏全面正确的认识。追踪研究设计可以依照重复测量之间的时间间隔长短进行分类, 不同的类型对应不同的样本量、调查方式和统计分析方法, 未来可以拓展追踪研究在团队和领导力、组织文化和变革以及员工激励等方面的应用, 或开展跨文化的追踪研究。     

小学儿童数学焦虑的潜在类别转变及其父母教育卷入效应：3年纵向考察

研究采用潜在转变分析考察小学儿童数学焦虑的类别转变以及父母教育卷入在小学儿童数学焦虑类别转变中的作用。以1720名三、四年级儿童为被试, 对其数学焦虑和感知到的父母教育卷入进行3次追踪, 每次间隔1年。结果表明：(1)小学儿童数学焦虑存在低数学焦虑组、高数学评估焦虑组和高数学获得焦虑组3种不同类别; (2)随时间的推移, 高数学评估焦虑组倾向于向低数学焦虑组转变, 高数学获得焦虑组倾向于向高数学评估焦虑组转变, 而低数学焦虑组稳定性较强; (3)父亲/母亲教育卷入对儿童数学焦虑类别转变的预测作用, 因不同的数学焦虑类别而异。上述发现为深入理解数学焦虑的形成机制以及干预措施的制定提供了重要参考。
