医师职业素养评测体系构建的研究进展

随着我国社会经济的发展,医疗体制的改革,医师职业素养的培养成为当今医疗体制下医学在校教育、住院医生培养、医疗卫生管理中必须关注的内容。目前国外对医师职业素养的培养做了大量的工作,也取得了较好的效果,但是对于职业素养的培养不仅需要理论教学的改革,更需要相应评估机制的建立。本文对国外医师执业素养评估的最新进展进行介绍,分析各种方法的优劣,以期为国内医学教育建立统一的、具有广泛公认度的测评体系提供参考。     

教师积极反馈与初一学生挫折反应模式的关系研究

目的：探究学生所具有的不同挫折反应模式是否会影响到教师对他们的反馈行为,以及进一步探究教师不同反馈类型如何影响持有不同反应模式的学生,为教师进行有针对性的教学反馈提供依据。 方法：研究1以102名初中教师为被试,采用角色扮演法,探究初中教师对学生的积极反馈行为是否会因学生挫折反应模式的不同而不同。研究2以291名初一学生为被试,采用集体施测的方法,探讨不同的积极反馈方式是否对不同挫折反应模式被试的后续反应产生不同的影响。 结果发现：（1）教师对无助反应模式的学生给予更多的个人积极反馈,而对掌握反应模式的学生给予更多的过程积极反馈;（2）个人积极反馈对无助反应模式的学生有更加消极的影响,而对于掌握反应模式的学生并无显著影响;（3）过程反馈和简单结果反馈有助于改善无助反应模式学生的后续反应;（4）过程积极反馈对两种反应模式的学生均未产生消极或积极影响。 结论：教师对无助反应模式的学生给予更多的个人积极反馈,而教师的个人积极反馈对无助反应模式的学生会产生更加消极的影响。     

Engagement With Personalized Feedback for Emotional Distress Among College Students at Elevated Suicide Risk

Depression and suicidal ideation have substantially increased among college students, yet many students with clinically significant symptoms do not perceive their distress as warranting mental health services. Personalized feedback (PF) interventions deliver objective data, often electronically, comparing an individual’s reported symptoms or behaviors to a group norm. Several studies have shown promise for PF interventions in the context of mood and depression, yet little is known regarding how, and for whom, mood-focused PF interventions might be best deployed. The primary aim of this study was to examine the sociodemographic, clinical, and treatment-seeking factors associated with reviewing PF reports on emotional distress among college students (N = 1,673) screening positive for elevated suicide risk and not receiving mental health treatment. Results indicated that PF engagement was greatest among those with higher depression scores, and those reporting privacy/stigma concerns as barriers to treatment. Sexual minority students were more likely to review their PF than heterosexual students. Taken together, PF interventions may be a useful tool for engaging those with greater clinical acuity, and those hesitant to seek in-person care. Further research is warranted to examine the circumstances in which PF interventions might be used in isolation, or as part of a multitiered intervention strategy.     

反馈对自我欺骗的影响：来自ERP的证据

本研究主要探讨反馈类型和反馈效价对自我欺骗的影响。实验1采用前瞻范式探究不同效价的模糊反馈对自我欺骗的影响, 结果发现, 相比于无答案提示组, 有答案提示组的被试在积极模糊反馈的条件下显著地提高测试2第二阶段的预测分数(自我欺骗的程度加重)。实验2探究不同效价的精确反馈对自我欺骗的影响, 结果发现, 相对于无答案提示组, 有答案提示组的被试在消极精确反馈条件下显著地降低测试2第二阶段的预测分数。实验3采用ERP技术探究反馈类型和反馈效价影响自我欺骗的内在机制, 结果发现, 模糊反馈条件下的自我欺骗诱发较大的P2成分、诱发较小的N1和N400成分; 以及发现自我欺骗在额区的效应较大。总之, 这些研究结果表明可能积极反馈促进个体的自我欺骗产生, 消极反馈削弱个体自我欺骗的产生; 积极模糊反馈能够进一步促进了个体自我欺骗的产生。这些研究结果还表明自我欺骗产生的背后机制可能是自我膨胀。     

心理理论与社会互动方式对初中生社会善念发展的影响

为了探讨初中生社会善念的发展特点及相关影响因素,实验1采用卡通插图范式和SoMi范式,以628名7~9年级初中生为被试,考察不同心理理论类型初中生的社会善念的发展;实验2使用社会互动情境和SoMi范式,以360名7~9年级初中生为被试,考察社会互动方式与反馈类型对不同年级初中生社会善念的影响。结果发现:(1)初中生的社会善念不存在年级和性别差异,但7年级中高情感心理理论初中生的社会善念显著多于高认知心理理论初中生;(2)7年级初中生在积极反馈条件下的社会善念较多,而8年级初中生在消极反馈条件下较多,9年级初中生在这两种条件下则不存在显著差异;(3)在合作情境中,初中生在积极反馈下的社会善念更多,而在竞争情境中,初中生在消极反馈下的社会善念更多。研究说明初中生的社会善念具有跨年龄和跨性别的稳定性,并且会受到心理理论、社会互动方式及反馈类型的影响。     

The effects of a local negative feedback function between choice and relative reinforcer rate

Four pigeons were trained on two-key concurrent variable-interval schedules with no changeover delay. In Phase 1, relative reinforcers on the two alternatives were varied over five conditions from .1 to .9. In Phases 2 and 3, we instituted a molar feedback function between relative choice in an interreinforcer interval and the probability of reinforcers on the two keys ending the next interreinforcer interval. The feedback function was linear, and was negatively sloped so that more extreme choice in an interreinforcer interval made it more likely that a reinforcer would be available on the other key at the end of the next interval. The slope of the feedback function was -1 in Phase 2 and -3 in Phase 3. We varied relative reinforcers in each of these phases by changing the intercept of the feedback function. Little effect of the feedback functions was discernible at the local (interreinforcer interval) level, but choice measured at an extended level across sessions was strongly and significantly decreased by increasing the negative slope of the feedback function.     

The Good Behavior Game in preschool classrooms: An evaluation of feedback

The Good Behavior Game (GBG) is a popular group contingency implemented to decrease disruptive behavior in classrooms. However, despite numerous replications of the GBG, there are few direct comparisons evaluating the effectiveness of specific components of the GBG. In the present study, we directly compared the type of feedback delivered during the GBG on the effectiveness of the GBG to reduce disruptive behavior in two preschool classrooms. Results showed that delivering vocal feedback (e.g., “raise your hand”) alone or in combination with visual feedback (i.e., hatch marks) was superior to no feedback or visual feedback alone during the GBG. These results suggest that different variations of the GBG are not equally effective and that a collection of effective procedural variations from which teachers can choose would be beneficial.
