父母教养方式与初中生网络受欺负行为的关系:一项追踪研究

以491名初中生为研究对象,对其网络受欺负行为进行为期2年的4次追踪测试,同时测试其父母教养方式。采用潜变量混合增长模型探讨初中生网络受欺负行为的多种发展轨迹,并分析父母教养方式的影响。结果发现：（1）在2年时间内,初中生网络受欺负行为呈显著下降趋势;（2）初中生网络受欺负行为存在两种下降趋势,即快速下降与慢速下降;（3）父亲拒绝、父亲过度保护与母亲拒绝这三种教养方式可增加两组初中生的网络受欺负行为,同时也可降低其网络受欺负行为的下降速度;（4）父亲情感温暖可显著预测快速下降组的初始水平和发展速度,母亲过度保护可显著预测慢速下降组的初始水平和发展速度,母亲情感温暖可显著负向预测慢速下降组的发展速度。上述结果证实父母教养方式对初中生网络受欺负行为发展轨迹的预测作用,支持了Kowalski网络欺负模型。     

儿童成长型思维干预的理论基础和实践走向

思维模式是人们关于智力是否可塑的内隐信念,是个体内隐意义系统的核心和组织者。个体的思维模式可以分为成长型思维和固定型思维,其中成长型思维有利于儿童学习动机、自我效能和心理韧性的发展。早期的儿童成长型思维干预主要采用面对面的方式,近年来线上的短时程干预得到了快速发展,进而促进了干预的规模化应用,干预的内容也从内隐智力理论拓展到内隐人格理论。对干预效果的评估显示,成长型思维干预能够对儿童学业发展和社会适应产生可持续的促进作用,且对学业困难群体作用更为显著。未来的研究应重视面向对象的干预程序开发,创建有利于成长型思维发展的环境,同时应注意避免实践中的简单化偏差。     

雾霾对地区GDP增长率的影响：抑郁情绪的中介效应

环境污染导致的天气变化对人的身心健康和社会发展都会产生重大影响。本研究以心理学的视角探讨雾霾天气是否会使人产生抑郁情绪,降低工作效率,进而影响社会经济发展。方法：收集2013-2015年中国大陆27个省会城市及4直辖市的PM2.5浓度、抑郁指数及地区生产总值增长率。采用百度统计平台基于关键词“抑郁”搜索量合成的抑郁指数作为抑郁情绪指标。结果表明：（1）2013-2015年各地区的PM2.5浓度与抑郁指数正相关显著(r= .33, p< .01),抑郁指数与地区GDP增长率的负相关显著(r= -.37, p< .01);（2）抑郁指数在PM2.5浓度和地区GDP增长率间起完全中介作用。（3）当lag=-6时,上海市2013年1月到2015年12月PM2.5浓度和抑郁指数的互相关系数最大(rR = .38, p< .05)。结论：雾霾天气可能会使人产生抑郁情绪,进而对经济增长产生负面影响。     

Estimation of a Latent Variable Regression Growth Curve Model for Individuals Cross-Classified by Clusters

The cross-classified multiple membership latent variable regression (CCMM-LVR) model is a recent extension to the three-level latent variable regression (HM3-LVR) model which can be utilized for longitudinal data that contains individuals who changed clusters over time (for instance, student mobility across schools). The HM3-LVR model can include the initial status on growth effect as varying across those clusters and allows testing of more flexible hypotheses about the influence of initial status on growth and of factors that might impact that relationship, but only in the presence of pure clustering of participants within higher-level units. This Monte Carlo study was conducted to evaluate model estimation under a variety of conditions and to measure the impact of ignoring cross-classified data when estimating the incorrectly specified HM3-LVR model in a scenario in which true values for parameters are known. Furthermore, results from a real-data analysis were used to inform the design of the simulation. Overall, it would be recommended for researchers to utilize the CCMM-LVR model over the HM3-LVR model when individuals are cross-classified, and to use a bare minimum of more than 100 clustering units in order to avoid overestimation of the level-3 variance component estimates.     

Bayesian PTSD-Trajectory Analysis with Informed Priors Based on a Systematic Literature Search and Expert Elicitation

There is a recent increase in interest of Bayesian analysis. However, little effort has been made thus far to directly incorporate background knowledge via the prior distribution into the analyses. This process might be especially useful in the context of latent growth mixture modeling when one or more of the latent groups are expected to be relatively small due to what we refer to as limited data. We argue that the use of Bayesian statistics has great advantages in limited data situations, but only if background knowledge can be incorporated into the analysis via prior distributions. We highlight these advantages through a data set including patients with burn injuries and analyze trajectories of posttraumatic stress symptoms using the Bayesian framework following the steps of the WAMBS-checklist. In the included example, we illustrate how to obtain background information using previous literature based on a systematic literature search and by using expert knowledge. Finally, we show how to translate this knowledge into prior distributions and we illustrate the importance of conducting a prior sensitivity analysis. Although our example is from the trauma field, the techniques we illustrate can be applied to any field.     

The Relation of Career Adaptability to Work–Family Experience and Personal Growth Initiative Among Taiwanese Working Parents

This study aimed to explore the effect of career adaptability on 598 working parents in Taiwan. The results showed that career adaptability served an important role in moderating and mediating the effects between work–family conflict, work–family strength, and personal growth initiative.     

The Role of Social–Emotional Mediators on Middle School Students’ Academic Growth as Fostered by an Evidence‐Based Intervention

The authors describe a school counselor intervention delivered to a predominantly Hispanic group of 193 7th‐grade students. Using multilevel modeling, the authors found that participation resulted in greater rates of academic achievement, particularly in math and for students who pretested at lower achievement levels. Results indicated an indirect effect on math achievement for the executive functioning constructs of plan and organize and task completion, but no executive functioning mediators were found for reading or feelings of connectedness.     

Three Futures: Nightmare,Diversion, Vision

Possible futures can, for simplicity, be reduced to three broad options: “Business-as-usual economic growth” (“Nightmare”), “Green economic growth” (“Diversion”), and “Ecological sustainability” (“Vision”). We critically discuss the feasibility and sustainability of each. We find that the Nightmare option will eventually be undermined by ecological deterioration and rising resource scarcity, while the Diversion option, we argue, is doomed to failure. The Vision option is for us the only viable future, but requires unprecedented socioeconomic changes. Regardless of path, either Earth biophysical changes, or socioeconomic changes—or possibly both—will be unprecedented. Hence, predicting the future, never easy, will become much harder.     

创伤暴露程度对中学生创伤后成长的影响——复原力的调节作用

采用修订后的创伤后成长问卷（PTGI）、复原力量表（CD-RISC）以及自编的震后创伤暴露程度调查表对汶川地震后异地复学的166名中学生进行问卷调查,探讨复原力在创伤暴露程度和创伤后成长关系中的调节作用。结果表明：主观害怕程度对创伤后成长有正向预测作用,主观害怕程度越高,创伤后成长的水平越高;复原力对主观害怕程度和创伤后成长之间的关系起增强作用;复原力对房屋损毁和创伤后成长之间的关系有一定的增强作用。     

Desensitization to media violence over a short period of time

This study investigated the desensitization to violence over a short period of time. Participants watched nine violent movie scenes and nine comedy scenes, and reported whether they enjoyed the violent or comedy scenes and whether they felt sympathetic toward the victim of violence. Using latent growth modeling, analyses were carried out to investigate how participants responded to the different scenes across time. The findings of this study suggested that repeated exposure to media violence reduces the psychological impact of media violence in the short term, therefore desensitizing viewers to media violence. As a result, viewers tended to feel less sympathetic toward the victims of violence and actually enjoy more the violence portrayed in the media. Additionally, desensitization to media violence was better represented by a curvilinear pattern, whereas desensitization to comedy scenes was better represented by a linear pattern. Finally, trait aggression was not related to the pattern of change over time, although significant effects were found for initial reports of enjoyment and sympathy. Aggr.
