中小学生正念注意觉知与心理健康：情绪调节和积极重评的跨时间中介作用

本研究探讨中小学生正念注意觉知的发展及其与心理健康的关系,并考察情绪调节和积极重评在其中起到的中介作用。研究采用追踪设计,来自江西地区两所小学(4到6年级)和两所中学(7到9年级)的共1251名学生(男生691人,女生560人)在间隔半年的两个时间点分别填写了测量正念注意觉知、心理健康(生活满意度、抑郁、焦虑、学业压力)、情绪调节以及积极重评的问卷。结果表明：(1)中学生正念注意觉知显著低于小学生;(2)中小学生正念注意觉知与两个时间点的情绪调节、积极重评及心理健康均显著相关;(3)跨时间点中介效应检验结果表明,在中小学生正念注意觉知和各心理健康变量的关系中,情绪调节中介效应均显著,积极重评中介效应均不显著。结论：中小学生正念注意觉知与心理健康密切相关,正念注意觉知通过情绪调节能力间接作用于中小学生心理健康。

Stress,social support,and problem-solving appraisal/skills: Prediction of suicide severity within a college sample

This study assessed whether stress, social support, and interpersonal problem-solving appraisal/skills were predictive of level of suicidality within a chronic suicidal college sample. Stepwise regression analyses were used to assess whether stress, social support, and problem-solving were independently predictive of severity of suicide ideation. In addition, hierarchical regression analyses were used to test the mediational nature of social support and problem-solving in the stress-suicidality relationship. Problem-solving confidence was found to be a significant predictor of severity of suicide ideation. In addition, both perceived problem-solving skills and social support mediated the relationship between stress and level of suicide ideation. However, only one of the two perceived problem-solving skills interactions was in the expected direction. This study provided support for the importance of problem-solving confidence and the interaction of stress and social support in the prediction of suicide severity. Unlike previous studies, this study did not find problem-solving skills/deficits to mediate the stress-suicidality relationship.This research was supported by NIMH Grant 1-18MH48133.     

“行高人非”还是“见贤思齐”？职场上行比较对员工行为的双刃剑效应

本研究基于压力认知评估理论,从理性认知视角探讨了职场上行比较存在的提升自我和贬损他人效应,以及驱动不同路径效应生效的边界条件和传导机制。本研究通过轮询设计,在3个时间点收集了来自60个团队240位成员的720份人际配对样本,并采用社会关系模型分析数据得出以下结论:在低水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为挑战,进而激发员工向上行比较对象的学习行为;相反,在高水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为威胁,进而驱使员工采取针对上行比较对象的社会阻抑。     

Modelling multiple problem-solving strategies and strategy shift in cognitive diagnosis for growth

Problem-solving strategies, defined as actions people select intentionally to achieve desired objectives, are distinguished from skills that are implemented unintentionally. In education, strategy-oriented instructions that guide students to form problem-solving strategies are found to be more effective for low-achieving students than the skill-oriented instructions designed for enhancing their skill implementation ability. Although the existing longitudinal cognitive diagnosis models (CDMs) can model the change in students' dynamic skill mastery status over time, they are not designed to model the shift in students' problem-solving strategies. This study proposes a longitudinal CDM that considers both between-person multiple strategies and within-person strategy shift. The model, separating the strategy choice process from the skill implementation process, is intended to provide diagnostic information on strategy choice as well as skill mastery status. A simulation study is conducted to evaluate the parameter recovery of the proposed model and investigate the consequences of ignoring the presence of multiple strategies or strategy shift. Further, an empirical data analysis is conducted to illustrate the use of the proposed model to measure strategy shift, growth in skill implementation ability and skill mastery status.     

The Effects of Leader Support for Creativity and Leader Gender on Subordinate Creative Problem-Solving Performance

Ample correlational research shows that leader support for creativity is related to subordinate creativity, yet research examining the causality of this relationship experimentally is scant. Furthermore, most studies that demonstrate support for this relationship have used relatively subjective creativity measures that do not tap as effectively into the creative problem-solving process. Thus, we experimentally examined whether leader support for creativity affects subordinate creative problem-solving performance. We also examined whether this relationship depends on leader gender. We used experimental vignette methodology and a sample of 247 working adults to test these relationships. We found that high (vs. low) leader support for creativity resulted in a significantly higher number of ideas generated. Additionally, posthoc analyses showed that high (vs. low) leader support for creativity resulted in a significantly higher number of original ideas and higher number of quality ideas generated. We also found that when the leader was a woman (vs. man), average originality of ideas was significantly higher. We found no significant interactive effects of leader support for creativity and leader gender. We discuss how this study further elucidates our understanding of leader support for creativity, as well as avenues for future creativity research involving leader gender.     

Social problem-solving in dual diagnosis patients

Social problem-solving skills among dual-diagnosis patients were compared to two control groups: psychiatric patients without substance abuse problems and community volunteers. A standardized, behavioral role-play test consisting of four scenarios representing interpersonal problems yielded two reliable dependent variables: (a) specificity, or elaboration, of the problem-solving response and (b) overall effectiveness of the response. Analyses of covariance (using a measure of intellectual function as the covariate) indicated that both dual-diagnosis patients and psychiatric controls were significantly poorer problem-solvers than were community controls. The overall pattern of the results indicated that deficits observed in a dual-diagnosis sample are not necessarily compounded due to the presence of the coexisting disorders. Implications of these findings, strengths and limitations of this study, and suggestions for future research are discussed.This research was supported in part by Grant DA04593-01 from the National Institute on Drug Abuse.Portions of this article were presented at the 22nd Annual Meeting of the Association for the Advancement of Behavior Therapy during November 1988 in New York.     

Beliefs about obsessional thoughts

Recent cognitive-behavioral formulations of obsessive-compulsive disorder postulate that intrusive or obsessional thoughts are subject to appraisal. Extreme beliefs about the occurrence and meaning of intrusive thoughts direct appraisal, thus causing marked distress and subjective responsibility which may lead to neutralizing activity. A brief self-report belief inventory was developed from a 92-item pool to assess extreme beliefs concerning intrusive thoughts and responsibility, the control of such thoughts and their possible consequences, and the appropriateness of guilt and neutralizing behavior as a response. The inventory was developed sequentially on two nonclinical samples (N=125, N=265) to distinguish between neutralizing and nonneutralizing subjects. Initial psychometric data for the final instrument were obtained for two further nonclinical samples (N=61, N=50) along with a sample of OCD patients and a matched control group. The instrument showed satisfactory reliability and evidence of criterion, convergent, discriminant, and factorial validity. Finally, data from a heterogeneous outpatient medical sample (N=299) was used to test the relationship among obsessive-compulsive symptoms, mood state, and beliefs. The implications of these results for contemporary models of obsessive-compulsive disorder are discussed.     

Mathematical progress: Between reason and society

It is shown how the historiographic purport of Lakatosian methodology of mathematics is structured on the theme of analysis and synthesis. This theme is explored and extended to the revolutionary phase around 1800. On the basis of this historical investigation it is argued that major innovations, crucial to the appraisal of mathematical progress, defy reconstruction as irreducibly rational processes and should instead essentially be understood as processes of social-cognitive interaction. A model of conceptual change is developed whose essential ingredients are the variability of rational responses to new intellectual and practical challenges arising in the cultural environment of mathematics, and the shifting selective pressure of society. The resulting view of mathematical development is compared with Kuhn's theory of scientific paradigms in the light of some personal communications.
