Psychometric Properties of the Revised Chen Internet Addiction Scale (CIAS-R) in Chinese Adolescents

The Revised Chen Internet Addiction Scale (CIAS-R) was developed to assess Internet addiction in Chinese populations, but its psychometric properties in adolescents have not been examined. This study aimed to evaluate the factor structure and psychometric properties of CIAS-R in Hong Kong Chinese adolescents. 860 Grade 7 to 13 students (38 % boys) completed the CIAS-R, the Young’s Internet Addiction Test (IAT), and the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) in a survey. The prevalence of Internet addiction as assessed by CIAS-R was 18 %. High internal consistency and inter-item correlations were reported for the CIAS-R. Results from the confirmatory factor analysis suggested a four-factor structure of Compulsive Use and Withdrawal, Tolerance, Interpersonal and Health-related Problems, and Time Management Problems. Moreover, results of hierarchical multiple regression supported the incremental validity of the CIAS-R to predict mental health outcomes beyond the effects of demographic differences and self-reported time spent online. The CIAS is a reliable and valid measure of internet addiction problems in Hong Kong adolescents. Future study is warranted to validate the cutoffs of the CIAS-R for identification of adolescents with Internet use problems who may have mental health needs.     

行政执法类公务员绩效考核指标体系研究

以工作分析为基础,对我国行政执法类公务员的绩效考核指标体系进行了研究.通过对云南省工商、药监、质检三个部门执法职能处室公务员的访谈和问卷调查,编制了行政执法类公务员绩效考核评价问卷.运用项目分析、探索性因素分析、验证性因素分析等方法,构建了行政执法类公务员绩效考核的指标体系,共包括9个二级指标和27个三级指标.问卷的内部一致性系数达到0.859,表明一致性信度良好;各维度与问卷总分的相关在0.543 ～0.782之间,且达到显著水平,说明各分问卷与总问卷的整体概念较为一致;验证性因素分析结果显示,修正后的二阶模型拟合指标中,绝对拟和指数x2/df、近似误差均方根RMSEA和相对拟合指数NNFI、CFI和IFI都达到了理想水平,说明问卷的结构效度良好.再以层次分析法对该绩效考核指标体系赋权重,使其更加合理且易于操作,具有应用价值.     

压力下一搏：压力如何影响个体风险寻求

压力促使个体风险寻求已得到许多研究的验证和支持, 但对于该现象背后的根本机制缺乏深入探讨和整合。模型指出, 压力诱发认知资源损耗和心理需要失衡, 导致个体执行控制功能减弱, 奖赏寻求增加, 这两者引起对风险选项价值的高估、风险感知的降低和启发式决策策略的使用, 最终导致风险寻求。期望效用论、预期理论、双系统理论和风险敏感理论的视角能各有侧重地解析模型中的路径。最后, 基于模型梳理了边界条件, 并提出未来可关注压力下执行功能、认知和情绪的交互以及慢性压力的影响和调控。     

不同语义水平下参照方式、情绪效价和特质评价对记忆的影响

为了探索影响记忆的深层次因素及其作用机制,采用内隐实验范式,考察了不同语义水平下参照方式、情绪效价和特质评价对记忆的影响。结果发现,参照方式、情绪效价和特质评价分别对记忆产生了显著的影响;在不同语义水平下,自我相关的特质词和非特质词的记忆优势表现在不同的再认提取阶段;个体对自我相关的消极词表现出显著的记忆优势;参照方式、情绪效价和特质评价的交互作用不显著。结果表明,参照方式、情绪效价和特质评价是对记忆产生影响的独立因素,但参照方式对记忆的影响受到情绪效价和特质评价的制约。     

一种基于进化算法的概化理论最佳样本量估计新方法：兼与三种传统方法比较

概化理论在心理与教育测量领域应用较广。如何使测量程序在预算限制的情况下达到较优的可靠性是研究者需要考虑的重要问题, 这个问题可以转换为最佳样本量估计的问题。提出了一种基于进化算法的估计概化理论下最佳样本量的新方法——约束进化算法, 并采用模拟研究的方法比较了微分优化法、拉格朗日法、柯西不等式法等三种传统方法与约束进化算法的优劣。结果表明：在两侧面交叉设计、两侧面嵌套设计和三侧面交叉设计中都证明了约束进化算法更具优越性, 建议研究者在今后的研究中优先使用。     

教师创造性教学行为与小学生创造性思维的关系：有调节的中介模型

以471名小学生为被试,采用儿童报告法考察教师创造性教学行为与小学生创造性思维的关系,同时探析小学生创意自我效能感的中介作用以及开放性人格的调节作用。结果发现:(1)在控制儿童性别、年龄和父母受教育程度后,感知到的教师创造性教学行为显著正向预测小学生创造性思维的流畅性、变通性和独特性;(2)感知到的教师创造性教学行为可以通过创意自我效能感影响小学生创造性思维的流畅性、变通性和独特性;(3)开放性人格能够调节感知到的教师创造性教学行为对小学生创意自我效能感的作用,个体开放性人格水平越高,小学生感知到的教师创造性教学行为对创意自我效能感的预测作用越强。研究表明,创意自我效能感和人格开放性可能是教师创造性教学行为与学生创造性思维关联的重要机制,改善教师的创造性教学行为,提高创意自我效能感和人格开放性水平,有助于促进小学生的创造性思维发展。     

How organizational cultures shape social cognition for newcomer voices

Drawing on cue consensus theory and status characteristics theory, we argue that the consensus between newcomer voice (challenging vs. supportive) and organizational culture (individualistic vs. collectivistic) leads to observers' social cognition of warmth or competence. Based on two survey studies and two experiment studies, we found that individualistic organizational culture strengthens the positive relationship between challenging voice and perceived competence and that voice constructiveness mediates this moderating effect. We also found that collectivistic organizational culture strengthens the positive relationship between supportive voice and perceived warmth, and prosocial motivation mediates this moderating effect. Focusing on consistent cues between voice and organizational culture, our research contributes to the voice literature, answering when and how both newcomer challenging voice and supportive voice can lead to perceived warmth and competence. Our results offer both theoretical implications and practical insights for employees and organizations.     

父母心理控制与青少年智能手机成瘾:心理需求网络满足和环境敏感性的作用

本研究探讨了父母心理控制与智能手机成瘾的关系,以湖北省某中学的1320名高中生为被试,采用问卷法考察了心理需求网络满足在父母心理控制和智能手机成瘾关系间的中介效应,以及环境敏感性对这一中介过程的调节效应。结果发现：（1）在控制了手机使用频率后,父母心理控制对智能手机成瘾具有显著正向预测作用;（2）心理需求网络满足在父母心理控制和智能手机成瘾之间起中介作用;（3）中介链条的后半段,即心理需求网络满足和智能手机成瘾的关系受到环境敏感性的调节。具体来说,对于高环境敏感性的人,心理需求网络满足对智能手机成瘾的正向预测作用明显增强。     

Developing agency through good work: Longitudinal effects of job autonomy and skill utilization on locus of control

An internal locus of control has benefits for individuals across multiple life domains. Nevertheless, whether it is possible to enhance an individual's internal locus of control has rarely been considered. The authors propose that the presence of job autonomy and skill utilization in work can enhance internal locus of control, both directly and indirectly via job satisfaction. Three waves of data over a four-year period from the Household, Income and Labour Dynamics in Australia Survey (N = 3045) were analyzed. Results showed that job autonomy directly shaped internal locus of control over time, as did job satisfaction. Skill utilization did not play a role in terms of affecting locus of control, and the indirect effects of both job autonomy and skill utilization via job satisfaction were weak. This study suggests the importance of job autonomy in promoting the development of an employee's internal locus of control.
