The Impacts of Ignoring a Crossed Factor in Analyzing Cross-Classified Data

Cross-classified random-effects models (CCREMs) are used for modeling nonhierarchical multilevel data. Misspecifying CCREMs as hierarchical linear models (i.e., treating the cross-classified data as strictly hierarchical by ignoring one of the crossed factors) causes biases in the variance component estimates, which in turn, results in biased estimation in the standard errors of the regression coefficients. Analytical studies were conducted to provide closed-form expressions for the biases. With balanced design data structure, ignoring a crossed factor causes overestimation of the variance components of adjacent levels and underestimation of the variance component of the remaining crossed factor. Moreover, ignoring a crossed factor at the kth level causes underestimation of the standard error of the regression coefficient of the predictor associated with the ignored factor and overestimation of the standard error of the regression coefficient of the predictor at the (k?1)th level. Simulation studies were also conducted to examine the effect of different structures of cross-classification on the biases. In general, the direction and magnitude of the biases depend on the level of the ignored crossed factor, the level with which the predictor is associated at, the magnitude of the variance component of the ignored crossed factor, the variance components of the predictors, the sample sizes, and the structure of cross-classification. The results were further illustrated using the Early Childhood Longitudinal Study-Kindergarten Cohort data.     

School Connectedness and Problematic Internet Use in Adolescents: A Moderated Mediation Model of Deviant Peer Affiliation and Self-Control

Although a growing body of research documents the negative association between school connectedness and adolescent problematic Internet use (PIU), little is known about the mediating mechanism (i.e., how school connectedness relates to PIU?) and moderating mechanism (i.e., when the protection is most potent?) underlying this relation. The present study examined whether deviant peer affiliation mediated the relationship between school connectedness and PIU, and whether this mediating process was moderated by adolescent self-control. A total of 2,758 Chinese adolescents (46 % male; mean age?=?13.53 years, SD?=?1.06) from 10 middle schools completed anonymous questionnaires regarding school connectedness, deviant peer affiliation, self-control, and PIU. After controlling for gender, age, socioeconomic status, and parental attachment, it was found that the negative association between school connectedness and adolescent PIU was partially mediated by deviant peer affiliation. Moreover, this indirect link was stronger for adolescents with low self-control than for those with high self-control. These findings underscore the importance of integrating the social control theory and organism-environment interaction model to understand how and when school connectedness impacts adolescent PIU.     

Is expressive suppression an effective coping strategy? A study of Chinese rescue medical staff following an earthquake

The current study examined the function of expressive suppression among Chinese rescue medical staff following a major earthquake. We administered self‐report questionnaires to (1) a sample of Chinese hospital medical staff (n = 305) who assisted victims of the Sichuan earthquake, and (2) a second sample of Chinese hospital medical staff (n = 149) who had not been exposed to a major stressor. To examine possible interaction effects among differing emotion regulation strategies, we also conducted structured interviews with a subset of rescue medical staff to obtain support for a positive function of expressive suppression and a mediating role of positive reappraisal. Structural equation modelling indicated that expressive suppression was associated with higher levels of job engagement and lower levels of job burnout among the rescue medical staff and that these effects were mediated by positive reappraisal. However, for regular medical staff (not exposed to traumatic stress), expressive suppression was associated with higher levels of both job engagement and job burnout; these effects were mediated by acceptance. These results provide preliminary evidence for the positive role of expressive suppression within Chinese culture.     

自我损耗下积极情绪对亲社会行为的影响

基于自我控制资源理论,本研究通过2个递进实验探究自我损耗下积极情绪对亲社会行为的影响。实验1采用“非利手写作”任务操纵被试的自我损耗,并诱发积极情绪,以被试在独裁者任务中分配的代币数为亲社会行为的衡量指标。结果发现：相比于低损耗组,高损耗组亲社会行为水平更低;诱发积极情绪能够补偿自我控制资源。实验2在此基础上,诱发高、低趋近动机积极情绪,考察自我损耗状态下不同强度趋近动机积极情绪对亲社会行为的影响。结果表明,低趋近动机积极情绪能缓解自我损耗后效。本研究证实了提高自我损耗将降低个体亲社会行为水平,诱发低趋近动机积极情绪可以缓解该效应。

“平分秋色”与“三足鼎立”:适应功能视角下拒绝敏感性的新结构取向

拒绝敏感性是个体对拒绝信息的焦虑预期、准备性知觉和过度反应的倾向。以往研究多以单因素的视角考察整体拒绝敏感性,但近年来其结构取向出现了转变趋势,研究者开始从适应功能的视角分别关注其二因素(即焦虑预期、愤怒预期)与三因素结构(即焦虑成分、愤怒成分和拒绝预期),且发现不同结构取向对个体的适应功能具有不同影响,焦虑预期与内化行为问题有关,愤怒预期与外化行为问题有关,而拒绝预期作为认知成分也需要加以重视。未来亟需从性别差异、行为及神经科学证据、本土化研究、年龄差异、针对性干预措施五方面对不同结构进一步深入探索。     

Temporal Discounting Mechanisms of Future‐oriented Coping: Evidence from Delay Discounting and Task Prioritization Paradigms

Four studies were conducted to examine the relationship between future‐oriented coping and temporal discounting under different situational conditions. In Study 1, 138 participants were primed with either stressful or neutral stimuli, followed by a delay‐discounting task. In Study 2, 118 participants were primed with either stressful or neutral stimuli, followed by a task‐prioritization activity. The results of both studies indicated that future‐oriented coping had a significant negative association with temporal discounting or the number of rational choices in the neutral‐priming condition, but the relationship was not significant in the stress‐priming condition. In Study 3, qualitative data revealed that the major reason for shifting choices from larger but later payoffs to smaller but sooner rewards in a stressful condition was to reduce the stressful mood, create a positive mood, and promote a sense of accomplishment. This explanation was corroborated by Study 4, in which one group was allowed to choose an immediate payoff and the other group was blocked from choosing that immediate payoff. We confirmed that post‐test anxiety was significantly lower in the immediate payoff group compared with the delayed‐payoff group in proactive and preventive coping, using pre‐test anxiety as a covariate. Preventive coping helped to reduce anxiety levels in a stressful condition only when there was a choice to obtain an immediate payoff. These findings underscore the relationship between future‐oriented coping and temporal discounting, as well as the flexibility of discounting in the face of stress.

基于多元回归的调节效应分析

在心理学和其他社科研究领域,大量实证研究建立调节模型,以分析自变量对因变量关系的影响机制,但在基于多元回归的调节效应分析实践中仍存在不足。我们回顾了均值中心化在基于多元回归的调节效应分析中的作用,均值中心化不影响乘积项(即调节效应)的检验,仅对一阶项(即主效应)的检验有影响。讨论了简单斜率的检验方法,建议在调节变量为连续变量时,使用Johnson-Neyman法进行简单斜率检验;在调节变量为类别变量或研究者对某个调节变量值感兴趣时,使用选点法。并用一个实际例子演示如何进行调节效应分析。随后展望了调节效应检验的拓展方向。
