生活事件与大学生自杀意念的关系——气质性乐观的调节作用

目的在医学生中探讨气质性乐观、生活事件与自杀意念的关系。方法采用自杀意念自评量表以及乐观问卷、青少年生活事件量表对两所医学院校的800名临床医学专业学生进行调查。结果①应激事件对医学生的自杀意念水平有正向预测作用,应激事件越严重,学生的自杀意念水平越高;②气质性乐观对应激事件与自杀意念之间的关系具有调节作用。结论气质性乐观是负性生活事件与自杀意念之间的调节器。     

Lmx And Job Tension: Linear And Non-Linear Effects And Affectivity

We examined whether linear or non-linear LMX-job tension relationships existed, and if these effects were consistent across levels of negative (NA) and positive (PA) affect. Results indicated that NA and PA moderated the non-linear LMX-job tension relationship. Specifically, the LMX-job tension association was best depicted by an inverted-U form for high NAs. Tension was highest when LMX was moderate and lowest when LMX was either low or high. Tension increased minimally for low NAs across levels of LMX. For high PAs, the relationship was linear and inverse. Conversely, a U-shaped form best represented the LMX-job tension relationship for low PAs. Implications, strengths and limitations, and directions for future research are discussed.     

Associated Factors of Suicide Among University Students: Importance of Family Environment

The aim in this study was to underline the importance of family environment as a significant associate of suicide probability among university students. For this aim 226 Turkish university students completed Suicide Probability Scale, Family Environment Questionnaire, Beck Depression Inventory, and Positive and Negative Affect Scale. As a result of the formulated regression analysis, after controlling for the 51% of the total variance accounted for by the control variables (i.e., gender, age, living with family versus away from family, and Grade Point Averages) and mood related variables (i.e., depressive symptoms, and positive and negative affect), family cohesion still emerged as a significant associate of the suicide probability. These findings underline the importance of family relations as a risk factor of suicide among university students.This work has been supported by the Turkish Academy of Sciences, in the framework of the Young Scientist Award Program.

药物成瘾理论的新进展

成瘾过程伴随着一系列脑机能和心理机能的改变,但对药物滥用如何导致这些改变以及它们如何诱发成瘾却存在着不同的解释。近年来,由于认知心理学和认知神经科学研究技术在该领域的应用,研究者对药物成瘾过程的认知机能及其脑机制获得了新的认识,且基于对负性生活事件及外部压力在维持药物滥用及诱发复吸行为中的作用的测量学研究和动物实验研究而提出的成瘾理论为该领域的研究开辟了新的思路。本文重点评述了药物成瘾的认知加工模型和以压力或负性情绪为核心的相关理论模型及其研究,并提出进一步研究的方向。     

Measuring generalised expectancies for negative mood regulation in China: The Chinese language Negative Mood Regulation scale

Negative mood regulation expectancies (NMRE) represent people's confidence that they can alleviate their negative affect or induce a positive emotional state through thought or action. NMRE predict coping behaviour and mood outcomes for individuals under stress. Since 1990, much research documents the reliability and validity of the English language Negative Mood Regulation (NMR) scale as a measure of NMRE. The current research reports two studies developing a Chinese language translation of the NMR (NMR‐C) scale that goes beyond literal translation to be a culturally sensitive measure of NMRE in China. In Study 1, 713 college students from both a major city and a rural setting in China were surveyed. Data support the resulting 32‐item NMR‐C's reliability (alpha = .88) and validity. The NMR‐C showed both direct and indirect links to depression and anxiety; coping mediated the indirect effect. In Study 2, 331 prison police officers in three Chinese provinces participated. NMRE buffered the effect of high role pressure, moderating the relationship between prison police role stress and job engagement. Results of the two studies support the reliability and validity of the Chinese language NMR scale and parallel results found with measures of NMRE in the West and in other Asian countries.     

Infant frontal EEG asymmetry moderates the association between maternal behavior and toddler negative affectivity

Relatively little work has examined potential interactions between child intrinsic factors and extrinsic environmental factors in the development of negative affect in early life. This work is important because high levels of early negative affectivity have been associated with difficulties in later childhood adjustment. We examined associations between infant frontal electroencephalogram (EEG), maternal parenting behaviors, and children’s negative affect across the first two years of life. Infant baseline frontal EEG asymmetry was measured at 5 months; maternal sensitivity and intrusiveness were observed during mother-child interaction at 5 and 24 months; and mothers provided reports of toddler negative affect at 24 months. Results indicated that maternal sensitive behaviors at 5 months were associated with less negative affect at 24 months, but only for infants with left frontal EEG asymmetry. Similarly, maternal sensitive behaviors at 24 months were associated with less toddler negative affect at 24 months, but only for infants with left frontal EEG asymmetry. In contrast, maternal intrusive behaviors at 5- and 24-months were associated with greater toddler negative affect, but only for infants with right frontal EEG asymmetry at 5-months. Findings suggest that levels of negative affect in toddlers may be at least partially a result of interactions between children’s own early neurophysiological functioning and maternal behavior during everyday interactions with children in the first two years of life.     

Personality predictors of the time course for lung cancer onset

Numerous findings suggest that personality is linked to the incidence and experience of negative health outcomes. More specifically, trait negative affect is negatively related to a number of health outcomes. The current study expands our understanding of the link between personality and disease by examining the time course for lung cancer onset. In a sample of patients who had recently undergone surgical resection for lung cancer, a variety of negative affect related personality variables were assessed to determine their relationship with age at surgery. After controlling for smoking behavior, it was found that trait negative affect was associated with time course for lung cancer onset, such that those with higher (vs. lower) levels of trait negative affect manifested lung cancer earlier in their lives. Thus, trait negative affect represents an independent risk factor among those prone to lung cancer (i.e., smokers).

The effects of rumination and negative cognitive styles on depression: a mediation analysis

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship between negative cognitive styles and level of depressive symptoms. A total of 115 college students and 38 patients suffering from depressive disorders completed a battery of questionnaires measuring levels of depressive symptoms, brooding, reflection, and negative cognitive styles. The results support the notion that there exist two distinct dimensions of rumination and that, of the two, it is brooding and not reflection that mediates the relationship between negative cognitive styles and depression and contributes to its negative outcomes.
