有中介的调节变量和有调节的中介变量

研究了有中介的调节效应模型和有调节的中介效应模型,两种模型都涉及到中介变量和调节变量。分别讨论了这两种模型的分析方法,两者基本上都是按中介效应模型的分析步骤,但其中都有一步要做调节效应的分析。还讨论了同时包含有中介的调节变量和有调节的中介变量的混合模型。最后,作为示范例子,用混合模型分析儿童行为对同伴关系的影响,结果发现,如果混合模型中的调节都设定是线性的,那么调节变量对因果关系是二次调节     

变革型领导的中介变量：一个整合的视角

目前文献中对于变革型领导作用机制的研究较为丰富,但缺乏对中介变量的系统归纳和梳理。变革型领导的影响路径可以从（1）心理认知的重新定位;（2）对社会关系的重新评价;（3）对工作环境的重新诠释三个方面来归纳。未来关于变革型领导作用机制的研究应从多层级研究、跨文化研究等方面展开     

小学儿童家庭环境、创意自我效能与创造力的关系

该文采用问卷法对473名小学五、六年级儿童的家庭环境、创意自我效能与创造力（创造性个性倾向和创造性思维）的关系进行调查,运用SPSS、AMOS等软件,进行数据的处理与分析。结果表明,家庭环境的知识性、创意自我效能与创造力之间显著正相关。创意自我效能在家庭环境、创造性个性倾向间,家庭环境的知识性与创造性思维的独创性间,家庭环境的知识性与创造力间起完全中介作用。     

知识验证信念对于多文本阅读理解的影响机制:阅读策略的中介效应和主题知识的调节效应

为厘清知识验证信念对于多文本阅读理解的影响机制,本研究构建了有调节的中介模型。采用知识验证信念量表、主题知识问卷和阅读策略量表,对于173名大学生进行调查,并要求其在多文本阅读理解之后进行开放问题回答。结果显示：精致化策略和信息收集策略在知识验证信念对于多文本阅读理解的影响中起部分中介作用;知识验证信念对于精致化策略的预测作用受到主题知识的调节。该结果不但展示了知识验证信念对于多文本阅读理解的间接影响机制,也提示了主题知识的作用在于提供了选择复杂策略的自由。     

共同因素心理治疗整合模式的回顾与评析

共同因素心理治疗整合模式是现代心理治疗整合运动中最早被提出的一种心理治疗整合模式。通过对共同因素整合模式的创建背景、发展历程及基本观点进行了梳理简述,认为其在促进心理治疗各流派融合的同时也人为地造成了“共同因素VS特异因素”新的对立,探讨了唯有建基于人的整合本性的心理治疗整合视野才能促进心理治疗整合运动未来的健康发展。     

What mediation analysis can (not) do

The present article is concerned with a common misunderstanding in the interpretation of statistical mediation analyses. These procedures can be sensibly used to examine the degree to which a third variable (Z) accounts for the influence of an independent (X) on a dependent variable (Y) conditional on the assumption that Z actually is a mediator. However, conversely, a significant mediation analysis result does not prove that Z is a mediator. This obvious but often neglected insight is substantiated in a simulation study. Using different causal models for generating Z (genuine mediator, spurious mediator, correlate of the dependent measure, manipulation check) it is shown that significant mediation tests do not allow researchers to identify unique mediators, or to distinguish between alternative causal models. This basic insight, although well understood by experts in statistics, is persistently ignored in the empirical literature and in the reviewing process of even the most selective journals.     

Control beliefs as a mediator of the relation between stress and depressive symptoms among inner-city adolescents

Adolescents' control beliefs were examined as a mediator of the relation between stress and depressive symptoms among a diverse sample of 445 inner-city adolescents. Results indicated that control beliefs significantly mediate the relation between stress and depressive symptoms. The specific direct effects of six individual stress domains (peer, family, school, neighborhood, economic, discrimination) on control beliefs and depressive symptoms were also examined. Results showed that (1) economic stress relates to adolescents' control beliefs, (2) family stress relates to adolescent depressive symptoms, and (3) peer stress relates to both control beliefs and depressive symptoms. Secondary analyses revealed that control beliefs significantly mediate the specific relations between peer stress and depressive symptoms. Results were not found to vary across ethnic groups. The implications of these findings for adolescent mental health and preventive interventions targeting depression are discussed.     

Testing indirect effect with a complete or incomplete dichotomous mediator

Past methodological research on mediation analysis mainly focused on situations where all variables were complete and continuous. When issues of categorical data occur combined with missing data, more methodological considerations are involved. Specifically, appropriate decisions need to be made on estimation methods of the indirect effects and on confidence intervals for testing the indirect effects with accommodations of missing data. We compare strategies that address these issues based on a model with a dichotomous mediator, aiming to provide guidelines for researchers facing such challenges in practice.     

On the relationship between item response theory and factor analysis of discretized variables

Equivalence of marginal likelihood of the two-parameter normal ogive model in item response theory (IRT) and factor analysis of dichotomized variables (FA) was formally proved. The basic result on the dichotomous variables was extended to multicategory cases, both ordered and unordered categorical data. Pair comparison data arising from multiple-judgment sampling were discussed as a special case of the unordered categorical data. A taxonomy of data for the IRT and FA models was also attempted.The work reported in this paper has been supported by Grant A6394 to the first author from the Natural Sciences and Engineering Research Council of Canada.     

内隐学习意识性研究的两种理论取向:二分与渐进

传统的内隐学习研究范式大多致力于意识与无意识加工的操作性分离。随着学习任务和测量手段的改进,越来越多的研究发现量化渐变比二元分离能更好地兼容实验数据。本文对认知领域中与二分和渐进两种取向相关的理论框架和实证研究进行介绍和评价,指出意识的二分与渐进假设是源自不同的概念定义层次的理论框架,即功能性概念和解释性概念,因而对现象学数据具有不同的解释效力。它们的共存提供了不同的研究视角,丰富了我们对内隐学习活动的认识。
