累积生态风险与高职生学习倦怠：消极自我图式和网络成瘾的中介作用

采用累积生态风险问卷、消极自我图式问卷、网络成瘾问卷以及学习倦怠问卷对湖南省4所高职院校的664名高职生进行调查,考察累积生态风险与高职生学习倦怠的关系以及消极自我图式、网络成瘾的中介作用。结果发现:(1)高职生累积生态风险、消极自我图式、网络成瘾和学习倦怠均呈显著正相关;(2)高职生累积生态风险对学习倦怠的直接效应和间接效应均显著。间接效应包括了三条路径:通过消极自我图式的中介作用、通过网络成瘾的中介作用以及通过消极自我图式和网络成瘾的链式中介作用。这一结论有助于理解累积生态风险对学习倦怠的作用机制,为降低高职生的学习倦怠提供参考建议。     

Effects of self–other decision-making on time-based intertemporal choice

The effects of self–other decision-making on intertemporal choice have been revealed in many studies using a monetary outcome. However, the outcome of intertemporal choice is not restricted to money; time is also a scarce and nonrenewable resource outcome. Thus, we conducted a series of experiments to address the effects of self–other decision-making on time-based intertemporal choice, a type of intertemporal choice that uses time as an outcome. Over the course of three experiments, differences in self–other decision-making were evidenced. Participants who made decisions for others were more likely to prefer the smaller but sooner (SS) option over the larger but later (LL) option and considered the gain of the SS option to be significantly greater than that of the LL option. Participants who made decisions for themselves were likely to prefer the LL option over the SS option. However, they considered the gains of the LL and the SS option to be indifferent. Changing the role of decision-making could affect the ability of individuals to consider the future consequences of their decisions. The effects of self–other decision-making on time-based intertemporal choice could be explained by the accounts of economic reasoning and construal level theory. The findings indicated that the effects of self–other decision-making on time-based intertemporal choice, which could be generated simply by rewording questions, can help individuals make optimal long-term choices without the need for increased control.     

职业乐观对组织承诺、求职行为的影响:有调节的中介模型

职业乐观是影响个体职业适应的重要因素之一。尽管以往文献大多认为职业乐观是有利的,然而职业乐观的个体也会出现求职行为,导致对现有工作的专注程度降低的负面影响。为了探讨职业乐观的双刃剑效应及其边界条件,通过2个时间点问卷调查法对581名企业员工进行调查,结果发现:(1)职业乐观对求职行为和组织承诺均有正向影响;(2)易变职业生涯定向在职业乐观对求职行为影响中起中介作用,工作归属感在职业乐观对组织承诺影响中起中介作用;(3)心理授权在职业乐观对易变职业生涯定向的影响中起负向调节作用,在职业乐观对工作归属感的影响中起正向调节作用。     

中文文本熟悉性在词切分和词汇识别中的作用

基于E-Z读者模型和中文阅读的整合模型, 词切分和词汇识别是否属于交互作用的统一过程存在争议。通过转换阅读方向来操纵文本熟悉性, 研究其在词切分和词汇识别中的作用。实验1考察中文文本熟悉性和词间空格促进作用之间的权衡。使用Eyelink 1000记录40名大学生在中文阅读中的眼动特征。结果发现：词间空格对中文阅读的促进作用在阅读训练后消失, 表明中文阅读中文本熟悉性和词间空格的促进作用之间存在权衡。实验2操纵文本熟悉性和词频来探究文本熟悉性在词汇识别中的作用, 结果发现：文本熟悉性和词频在早期指标上的交互作用; 阅读训练和词频不存在交互作用, 表明文本熟悉性影响词汇识别的早期加工阶段。研究结果表明中文阅读的词切分和词汇识别可能是顺序加工, 支持E-Z读者模型。     

默认选项设置的助推效果：来自元分析的证据

默认选项设置指通过设置默认选项以增加人们选择该选项可能性的助推方法, 近年来被越来越多地运用于促进公众积极行为上, 然而这种方法在有效性上却受到了来自公众和学者的质疑。据此, 本研究运用元分析法整合了近几年有关默认选项设置的已有实证研究, 分析该助推手段的有效性, 并进一步考察可能影响其有效性的相关变量。研究共纳入符合要求的原始文献56篇, 含92个研究, 结果发现：(1)默认选项设置的确能有效助推人们的行为; (2)默认选项设置的助推有效性在东、西方文化下存在显著差异, 其在西方文化背景下的助推效果要显著好于其在东方文化背景下的使用; (3)默认选项设置的助推有效性在不同情境应用领域中存在显著差异, 相较于健康和环保领域, 默认选项设置在金钱相关的情境领域下助推效果更好。     

青少年家庭功能与心理复原力的关系：一个有调节的中介模型

为探讨家庭功能、自我控制与青少年心理复原力的关系及其作用机制,采用家庭功能评定量表、自我控制量表、心理复原力量表对浙江省、山东省、河北省957名中学生进行调查。结果发现：（1）家庭功能对青少年心理复原力具有显著正向预测作用。（2）自我控制在家庭功能和青少年心理复原力之间起到部分中介作用。（3）家庭功能对青少年心理复原力中介过程的前半段路径受到性别调节,相比于女生,男生群体的家庭功能对自我控制的影响更为显著。     

Re-examining Citizenship: How the Control of Measurement Artifacts Affects Observed Relationships of Organizational Citizenship Behavior and Organizational Variables

We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined.

抑郁和焦虑与心血管疾病

抑郁焦虑与心血管疾病的关系最能体现身与心两者相互影响、不可分割的特点。但临床上,心血管疾病患者抑郁焦虑的诊疗率不足1％。这说明现有的诊疗理念和方式没有将心血管疾病和精神障碍联系起来,给患者全面全程的干预和管理。这样的缺陷不仅增加患者的痛苦和功能障碍,也增加心血管疾病的发病率和病死率,还增加患者及社会的医疗负担。本文结合临床经验,从心身一体的诊疗理念,谈谈抑郁焦虑与心血管疾病。     

Effects of psychological interventions for patients with osteoarthritis: a systematic review and meta-analysis

The aim of this study was to determine the effects of psychological interventions (e.g. cognitive restructuring, relaxation) on physiological and psychological health in osteoarthritis patients. A systematic literature search was done using PubMed, Embase, PsycINFO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database through November 2016. Studies were included if they used a randomized controlled trial designed to explore the effects of psychological interventions in osteoarthritis patients. Two independent authors assessed the methodological quality of the trials using criteria outlined by Jadad et al. Meta-analysis was done with the Revman5.0. Twelve randomized controlled trials, including 1307 osteoarthritis patients, met the study inclusion criteria. Meta-analysis showed that psychological interventions could reduce the levels of pain [standard mean difference (SMD) ?0.28, 95% CI ?0.48, ?0.08, P-value 0.005)] and fatigue (SMD ?0.18, 95% CI ?0.34, ?0.01, P-value 0.04). In addition, psychological interventions significantly improved osteoarthritis patients’ self-efficacy (SMD 0.58, 95% CI 0.40, 0.75, P-value 0.00) and pain coping (MD 1.64, 95% CI 0.03, 3.25, P-value 0.05). Although the effects on physical function, anxiety, depression, psychological disability were in the expected direction, they were not statistically significant. In conclusion, the role of psychological interventions in the management of osteoarthritis remains equivocal. Some encouraging results were seen with regard to pain, pain coping, self-efficacy, and fatigue. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.
