Psychache and suicidality in adult mood disordered outpatients in Brazil

Shneidman (e.g., 1998) has theorized that psychache--general psychological and emotional pain that reaches intolerable intensity--is an important suicide-related variable, and indeed, represents a source of suicidal behavior. This conceptualization, while prominent and clinically and intuitively appealing, has received relatively little empirical scrutiny. In this study, we determined whether an index closely related to psychache, psychological quality of life, would display a special and resilient association to suicidality among 60 adult psychiatric outpatients in Brazil. All patients underwent structured clinical interviews and completed various clinical and quality-of-life measures. We found that the association between psychological quality of life and suicidality remained, even when depression, hopelessness, and other domains of quality of life were controlled. Psychache appears to deserve its place among key suicide-related variables, and deserves the attention of clinicians working with suicidal people.     

父母心理控制与小学生的欺负行为:敌意归因和冷酷无情的作用检验

采用班级整群抽样法选取1847名3~6年级小学生（男生987名;平均年龄10.73±1.16岁）及其家长为被试,采用问卷法考察父母心理控制与小学生欺负行为的关系,同时探讨敌意归因和冷酷无情的中介作用。结果发现：（1）父母心理控制显著正向预测小学生的欺负行为;（2）冷酷无情在父母心理控制与小学生欺负行为间的关系中存在中介作用,敌意归因不发挥中介作用;（3）父母心理控制对小学生欺负行为影响的中介机制不存在显著的性别差异和学段差异。本研究结果表明,冷酷无情是父母心理控制影响小学生欺负行为的重要机制,但敌意归因不是。研究者和实践者应注重对欺负者情感加工能力的关注和干预。     

Rare targets are rarely missed in correctable search

Failing to find a tumor in an x-ray scan or a gun in an airport baggage screening can have dire consequences, making it fundamentally important to elucidate the mechanisms that hinder performance in such visual searches. Recent laboratory work has indicated that low target prevalence can lead to disturbingly high miss rates in visual search. Here, however, we demonstrate that misses in low-prevalence searches can be readily abated. When targets are rarely present, observers adapt by responding more quickly, and miss rates are high. Critically, though, these misses are often due to response-execution errors, not perceptual or identification errors: Observers know a target was present, but just respond too quickly. When provided an opportunity to correct their last response, observers can catch their mistakes. Thus, low target prevalence may not be a generalizable cause of high miss rates in visual search.     

冠心病的介入治疗——药物洗脱支架还是裸支架？

冠心病的治疗包括多种方式,在强化内科保守治疗的基础上,采用经皮冠状动脉介入治疗既可以改善患者的生活质量又能降低病死率。介入治疗中最重要的方式是支架植入。但应用药物洗脱支架,还是普通金属裸支架一直是近两年来的争论焦点。BASKET-LATE研究的发布,更给药物洗脱支架的应用蒙上了可怕的阴影。就我们现阶段的实际临床应用而言,只要服用足够长的至少双联抗小血板药物治疗,药物洗脱支架的应用还是安全的,而且临床主要心血管事件较裸支架明显降低。     

早产儿预防性应用抗生素的临床决策思路

近年来,随着对滥用抗生素所引起的细菌耐药性和二重感染的认识的逐步深入,预防性应用抗生素在临床上越来越受到限制.但由于早产儿感染的临床隐匿性和易并发严重并发症等特点,预防早产儿感染的发生和进一步的发展,就显得尤为重要.通过对早产儿发生感染的易感因素、感染诱因和临床特点的分析研究,来探讨早产儿临床预防应用抗生素的必要性、合理性及临床决策思路.     

从父母教育卷入到学业成就:自主支持与自主学习力的链式中介

家长教育卷入是为了提升学生的学业成就,但能否支持学生的自主学习从而提升其自主学习力,可能是提升学业成就的关键环节。研究将与自主学习相关的多种个人内部因素整合为自主学习力,对12万余名中小学生及其家长进行了大规模调查,建构了一个链式中介模型,分析显示父母教育卷入对学生学业成就的影响体现为两条路径:(1)父母主导路径:父母投入通过其自我报告的自主支持对学生学业成就产生显著影响;(2)学生发展路径:学生通过其所感知的父母自主支持提升其自主学习力,进而自主地促进其学业发展。研究提示,如何提高家长对学生“自主学习”的认识和支持能力,是家校协同促进学业发展的一个重要话题,也是保障“双减”不降学业成绩的一项关键举措。     

Subjective perception of health in elderly inpatients

There is evidence that subjective health is an important variable in general health outcomes. It can be an indicator of the individual's overall health status, creating a reliable and valid estimate about health. Quality of life (QoL) assessment can be associated with the individuals' subjective assessment of their own health status. The aim of the present study was to investigate variables associated with subjective perception of health in older inpatients. Ninety elderly inpatients over 60 years old were interviewed. The perception of health assessment (healthy/unhealthy) allocated elders in either of two groups. All the elders answered sociodemographic questions, the WHOQOL-100 and the Beck Depression Inventory (BDI). Comparing the group that considered themselves unhealthy to the other group, the former showed a tendency of worse QoL assessments in five out of six domains investigated. Significant differences were found for the physical and level of independence domains, as well as overall QoL. There was a significant association between health perception and lower intensity of depressive symptoms, as well as better QoL perception in the level of independence domain. This study shows the existence of an association between depressive symptoms and health assessment. It also suggests that the independence dimension is important in the elders' perception of their health status. These findings can help identify cause-effect relations between variables in aging studies involving health indicators and bring new intervention proposals for the elderly.     

情绪加工老龄化机制：表情的自动加工和控制加工视角

情绪加工老龄化已经成为老龄化研究的新热点, 但其内在机制仍然缺乏统一的解释。本研究以自动加工和控制加工为切入点, 综合行为实验、ERP和fMRI实验技术, 开展表情加工的老龄化研究, 从情绪与认知交互的角度进一步揭示情绪加工老龄化的内在机制。具体内容包括表情自动加工和控制加工的年龄差异及其神经机制, 表情自动加工与认知控制的相互作用, 以及个体差异在情绪加工老龄化中的作用等。本研究将加深对情绪加工老龄化的理解, 为相关理论模型的验证、修正和完善提供实证依据。     

Reentry Needs: Men Who Are Young,Hispanic, Older,or With Mental Illness

Perceptions of the needs for successful reentry among incarcerated men from diverse backgrounds were investigated using phenomenological qualitative methods. Twenty‐nine men serving time in a northeastern U.S. correctional facility, which concentrated on treatment of substance use, participated in four focus groups. Young men found it most important to make personal changes, Hispanic men to maintain personal identity, older men to receive structural support, and men with mental illness to connect with family.     

视觉长时记忆激活度对促进视觉短时记忆的影响

短时记忆与长时记忆的关系是记忆领域研究的重要内容。基于此, 研究者们就视觉长时记忆是否能促进视觉短时记忆的问题展开了大量研究, 但所得出的结论并不一致。通过不同程度的学习形成不同激活度的视觉长时记忆, 考察对几何图形的视觉长时记忆是否能对变化检测中的短时记忆起到促进作用。结果发现, 低激活水平的视觉长时记忆不能促进视觉短时记忆, 而事先存在且高度激活的视觉长时记忆对视觉短时记忆却具有促进作用; 同时, 随着视觉长时记忆激活水平的提高, 刺激间间隔的效应值也逐渐减小。本研究说明, 视觉长时记忆能否促进视觉短时记忆取决于视觉长时记忆的激活水平, 高激活的视觉长时记忆对阻止视觉短时记忆痕迹的迅速消退具有重要意义。
