Capturing the interplay among within- and between-person processes using multilevel modeling techniques

Multilevel modeling is an excellent way to analyze nested or clustered data of the type commonly collected through investigations into the linkages between psychological functioning and relationship processes. This article describes two especially relevant applications of multilevel modeling. The first application, growth curve analysis, is already familiar to many researchers and involves modeling individuals’ change trajectories over time and relating the derived change parameters to person-level characteristics or phenomena. The purpose of this paper is to emphasize a second application, multilevel process analysis, which involves modeling within-subject characteristics other than change over a representation of time. Multilevel analysis of within-subject processes is particularly well-suited for hypotheses common to clinical psychology investigations, yet has received substantially less attention in the literature than its growth curve counterpart. Types of research questions and methodologies that can be addressed within the multilevel process analysis framework are described. Finally, aspects of multilevel process analysis are demonstrated with daily diary data collected from wives who reported on their marital happiness and depressed mood for 3 weeks.     

我国近十年来心理学研究中HLM方法的应用述评

以2002-2011年中国期刊网收录的50例应用多层线性模型(HLM)的心理学期刊论文为研究对象,从样本描述、模型发展与规范、数据准备、估计方法与假设检验4个角度进行文献计量和内容分析,对我国心理学研究中HLM方法的使用现状进行评估。结果表明,HLM方法主要用于管理、发展和教育心理学,绝大多数应用都是两层模型且层2样本量较大。HLM方法在广泛应用的同时仍存在忽略前提假设检验、分析过程中的重要信息和结果报告不完整等问题,随后提供了4条建议。     

虚拟团队共享心理模型与团队效能的关系

通过对62个虚拟团队的调研,检验了虚拟团队认同式共享心理模型与分布式共享心理模型构思,并运用多层线性建模技术,对团队特征变量、共享心理模型与虚拟团队效能间的关系进行了分析。结果表明：两类共享心理模型与团队效能间存在显著正相关;团队时间会影响共享心理模型与虚拟团队任务效能间的关系,团队时间会削弱认同式共享心理模型对任务效能间的正向关系,但能加强分布式共享心理模型对任务效能的正面影响;团队规模则主要影响共享心理模型对合作效能的效应,团队规模增加会加强认同式共享心理模型与合作效能间的相关,却会削弱分布式共享心理模型与合作效能间的关系     

管理评价判断模型与策略获取

管理评价是在不确定情景中的一种多特征决策,非补偿策略是决策者所采用的主导判断模型。作为一种结构建模程序,策略捕捉可以建构包含决策标准及其权重的统计模型,获取决策内在过程和预测判断。多层线性模型能够方便地考察人内和人间变异,表征判断非线性结构,是分析策略捕捉数据的恰当方法。管理评价设计可以借鉴行为经济学和实验经济学的思路,实现对现实管理决策过程的抽象模拟。     

基于多层结构方程模型的情境效应分析—— 兼与多层线性模型比较

多层(嵌套)数据的变量关系研究, 必须借助多层模型来实现。两层模型中, 层一自变量Xij按组均值中心化, 并将组均值 置于层2截距方程式中, 可将Xij对因变量Yij的效应分解为组间和组内部分, 二者之差被称为情境效应, 称为情境变量。多层结构方程模型(MSEM)将多层线性模型(MLM)和结构方程模型(SEM)相结合, 通过设置潜变量和多指标的方法校正了MLM在情境效应分析中出现的抽样误差和测量误差, 同时解决了数据的多层(嵌套)结构和潜变量的估计问题。除了分析原理的说明, 还以班级平均竞争氛围对学生竞争表现的情境效应为例进行分析方法的示范, 并比较MSEM和MLM的异同, 随后展望了MSEM情境效应模型、情境效应无偏估计方法和情境变量研究的拓展方向。     

Using HLM to Explore the Effects of Perceptions of Learning Environments and Assessments on Students’ Test Performance

The study examines the role that perceptions or impressions of learning environments and assessments play in students’ performance on a large-scale standardized test. Hierarchical linear modeling (HLM) was used to test aspects of the Learning Errors and Formative Feedback model to determine how much variation in students’ performance was explained by students’ and school principals’ perceptions of learning environments and assessments. Results from sequential HLM testing indicated that students’ but not principals’ perceptions explained a significant, although modest, amount of the total variation in students’ test performance. These results suggest that when students perceive learning environments to be safe and valuable, and positive assessment activities to be taking place, they tend to perform better on standardized tests than when they perceive learning environments and assessment activities otherwise. These findings provide a rationale for investigating the variables that can help improve students’ perceptions in order to enhance their test performance.     

Personality and strength-related attitude dimensions: Between and within-person relationships

Examined personality variables as predictors and moderators of strength-related attitude dimensions (SRAD) using multilevel modeling. Results revealed significant person-level variation in attitude importance, extremity, and ambivalence across attitude objects. Study 1 found the personality variable of need to evaluate (NE) predicted extremity across attitude objects, and finding meaning in life (ML) was predictive of importance across objects. Study 2 revealed that neuroticism and state anxiety were significant predictors of ambivalence across attitude objects. Finally, the NE, the Need for Cognition, and Openness to Experience each moderated the within-person relationship between extremity and ambivalence across objects, with higher values on the individual difference variables being related to stronger within-person relationships. Implications for research on attitude strength and the relationships between personality variables and attitudes are discussed.     

空间情境提示效应及其机制

视觉环境中不变的空间布局信息能够引导观察者将注意快速指向特定的位置并促进对该位置上目标物体的识别,这种现象称为空间情境提示效应.在系统回顾以往研究的基础上,对空间情境提示效应的经典研究和实验范式,空间情境学习的性质、内容与过程,以及空间情境提示效应的产生机制和神经基础进行分析梳理.文章在最后总结了以往研究中存在的5个争议性的问题,并指出未来研究可以操纵研究材料和任务难度等关键变量来解决这些问题.     

Work-family climate, organizational commitment, and turnover: Multilevel contagion effects of leaders

This paper presents empirical research analyzing the relationship between work-family climate (operationalized in terms of three work-family climate sub-scales), organizational leadership (i.e., senior manager) characteristics, organizational commitment and turnover intent among 526 employees from 37 different hotels across the US. Using multilevel modeling, we found significant associations between work-family climate, and both organizational commitment and turnover intent, both within and between hotels. Findings underscored the importance of managerial support for employee work-family balance, the relevance of senior managers’ own work-family circumstances in relation to employees’ work outcomes, and the existence of possible contagion effects of leaders in relation to work-family climate.     

高中生自杀意念的素质-应激模型：多时段追踪研究

目的：探讨神经质人格和负性生活事件的跨层相互作用对自杀意念的影响。方法：采用自杀意念问卷、青少年生活事件问卷和大五人格量表-神经质分量表等自评量表对618名高中生进行评估,每三个月追踪1次,共追踪7次,历时21个月,用多层线性模型分析数据。结果：在控制了第一次自杀意念和性别的影响后,负性生活事件的主效应（b = 0.08, F(1, 2963) = 37.93, p < 0.001）、负性生活事件与神经质人格的相互作用（b = 0.03, F(1, 2963) = 4.35, p < 0.001）显著,而神经质人格的主效应不显著（b = 0.59, F(1, 557)= 3.05, p > 0.05）。结论：神经质人格和负性生活事件的跨层相互作用可以预测自杀意念的变化,支持素质-应激模型。
