Subject Matter Expert Judgments Regarding the Relative Importance of Competencies are not Useful for Choosing the Test Batteries that Best Predict Performance

Several recent articles have suggested that assessments of the relative importance of different abilities or competencies to a job have little bearing on the criterion‐related validity of these selection tests that measure those abilities. We hypothesize that selection test batteries chosen to maximize the judged importance of knowledge, skills, and abilities will not predict performance better than batteries of tests chosen at random. The results in two independent samples consistently show that the validity of test batteries chosen based on subject matter expert judgments of importance is not different from the validity of batteries of a comparable number of tests chosen at random from a set of intercorrelated tests, or even those chosen to provide the worst possible match between test content and job content.     

认知老化对于老年人决策过程的影响:动机的调节作用

有关老化和决策制定的研究并没有发现一致的年龄差异。从决策过程的角度,论述了老化对于决策制定的多层面影响。从认知层面来讲,流体认知能力的衰减会使老年人在决策制定前搜索更少的信息,使用非补偿性策略,基于属性进行信息搜索和比较;晶体认知能力的相对保持则在一定情况下弥补了这种消极影响;从动机层面来讲,关注情绪管理目标的老年人会倾向于寻求更多积极的信息,为了避免权衡诱发的消极情绪而更多地使用非补偿性策略。动机对于认知老化的消极影响有调节作用。具体来说,社会情绪选择理论和选择性投入假设认为,当决策任务符合老年人的社会目标,即情绪管理目标时,能够激活老年人投入认知资源的动机,从而缓解认知资源的衰减对于老年人决策表现的消极影响。未来的研究需要通过实验设计进一步探索动机与认知的交互作用,将多种过程追踪技术结合起来,明晰动机和认知能力在老年人决策制定中的作用。另外考虑到在社会目标方面的年龄差异,对于老年人决策质量的衡量应该更加注重主观决策质量。     

The Children’s Attention-Deficit Hyperactivity Disorder Telemental Health Treatment Study: Caregiver Outcomes

The Children’s Attention-deficit Hyperactivity Disorder (ADHD) Telemental Health Treatment Study (CATTS) tested the hypotheses that children and caregivers who received guideline-based treatment delivered through a hybrid telehealth service delivery model would experience greater improvements in outcomes than children and caregivers receiving treatment via a comparison delivery model. Here, we present caregiver outcomes. 88 primary care providers (PCPs) in seven geographically underserved communities referred 223 children (ages 5.5 ? 12.9 years) to the randomized controlled trial. Over 22 weeks, children randomized to the CATTS service delivery model received six sessions of telepsychiatry and six sessions of caregiver behavior management training provided in person by community therapists who were trained and supervised remotely. Children randomized to the comparison Augmented Primary Care (APC) service model received management in primary care augmented by a single telepsychiatry consultation. Caregiver outcomes included changes in distress, as measured by the Patient Health Questionnaire (PHQ-9), Parenting Stress Index (PSI), Caregiver Strain Questionnaire (CSQ) and Family Empowerment Scale (FES). Caregivers completed five assessments. Multilevel mixed effects regression modeling tested for differences between the two service delivery models in caregiver outcomes from baseline to 25 weeks. Compared to caregivers of children in the APC model, caregivers of children in the CATTS service model showed statistically significantly greater improvements on the PHQ-9 (β?=?-1.41, 95 % CI?=?[?2.74, ?0.08], p?<?.05), PSI (β?=??4.59, 95 % CI?=?[?7.87, ? 1.31], p?<?.001), CSQ (β?=??5.41, 95 % CI?=?[? 8.58, ?2.24], p?<?.001) and FES (β?=?6.69, 95 % CI?=?[2.32, 11.06], p?<?.01). Improvement in child ADHD symptoms mediated improved caregiver scores on the PSI and CSQ. Improvement in child ODD behaviors mediated caregiver CSQ scores. The CATTS trial supports the effectiveness of a hybrid telehealth service delivery model for reducing distress in caregivers of children with ADHD and suggests a mechanism through which the service model affected caregiver distress.     

童年中晚期友谊质量与抑郁的关系:一项纵向研究

以友谊质量问卷和儿童抑郁量表为研究工具,对小学3到4年级847名儿童进行了18个月的追踪研究,采用交叉滞后的研究设计,考察了童年中晚期友谊质量与抑郁的关系。结果表明：（1）同一时间点的友谊质量和抑郁之间呈显著的负相关;（2）早期的友谊质量可以显著预测随后的抑郁,早期的抑郁也可以显著预测随后的友谊质量,且相对于友谊质量对抑郁的积极作用,抑郁对儿童友谊质量的瓦解作用更为突出;（3）童年中晚期友谊质量与抑郁的双向作用关系具有跨性别稳定性。     

运用比较治疗学的方法促进T2DM胰岛素治疗决策的最优化

2型糖尿病（T2DM）为内分泌科常见疾病,胰岛素是最主要的治疗药物之一,但胰岛素治疗方法诸多,各种方案的疗效参差不齐。为了促进2型糖尿病治疗决策的最优化,本文通过利用检索国内报道的相关文献,对文献中2型糖尿病的胰岛素治疗方法进行归纳总结,并且运用比较治疗学的研究方法进行比较分析,旨在寻求最有效的治疗方案。     

伦理审查委员会的法律地位初探

伦理审查委员会(IRB)的法律地位是一个崭新的课题.通过解读我国现行的伦理审查规范,对我国IRB伦理审查活动的合法性、伦理审查结果的法律效力、IRB及研究人员的法律责任等关乎IRB法律地位的问题进行了探讨.考察了美国和瑞典的伦理审查法规,提出应该提高我国伦理审查规范的法律位阶,推行注册制度的建议.     

基于脑结构像的精神分裂症机器学习分类

将机器学习应用于精神疾患的临床和基础研究是近年来的趋势。研究者将机器学习应用于精神分裂症患者及高危人群的T1加权像和弥散张量成像的脑影像数据中, 为了解疾病的生理病理学机制提供帮助。回顾以往研究发现额叶及颞叶的脑结构特征具有较高的区分能力, 行为数据和脑影像数据结合的分类效果优于单模态数据。现阶段研究存在样本量不足和泛化能力欠缺的局限, 未来研究应注意扩大样本量、制定标准化的分类方法, 从而进一步探究机器学习在精神疾患中的作用。     

特质应对与展现规则对情绪劳动的影响

采用2×3组间设计, 检测特质应对(积极与消极)与展现规则(积极、消极、无规则)对情绪劳动的影响。结果表明, 积极应对引起更多深层动作; 积极规则下出现较少表层扮演(与消极应对比)。积极和消极规则都引起较多深层和表层动作。积极应对在积极规则下表层扮演较少(与消极规则比); 消极应对在积极规则下表层扮演较多(与消极规则比)。研究提示, 特质情绪性可能是调节展现规则与情绪劳动关系的重要原因。
