医学学术英语u1tb文章In 1955, during the dawn of the modern era of randomized clinical trials, Thomas Chalmers and his colleagues published a remarkable paper.1 It was then and probably remains one of the most detailed reports of clinical trials ever published: it begins with a Table of Contents and runs on to a further 71 pages of small type. It is a model of how randomized trials should be reported, reflecting Marc Daniels' call for better reporting of clinical trials five years earlier,2 and anticipating by over four decades the reporting standards agreed and promulgated by the CONSORT Group.3Tom Chalmers and his colleagues described the eligibility criteria of participants clearly, and their random allocation (with concealment of the next participant's assignment) into th eir 2?×?2 factorial trials,4 thus permitting comparisons of two regimens per trial. The similarity between treatment groups in respect of 34 other variables that might affect patient prognosis was confirmed. Experimental and control regimens were precisely defined, and compliance with them was closely monitored and reinforced. All patients were accounted for at the end of the trials. Analyses were clearly described and transparent. The ‘external validity’ of the trial results was tested by comparison with another, independent control group of patients. Finally, late effects of the treatment regimens were assessed in a 10-year follow-up study.I first came across this report in 1959. Although I failed to appreciate many of its methodological strategies and strengths at that time, it changed my career. I was a final-year medical student on a medical ward, where a teenager with ‘infectioushepatitis’ (now called ‘Type-A hepatitis’) was admitted to my care. He presented with severe malaise, an enlarged and tender liver, and a colourful demonstration of deranged bilirubin metabolism that made me the envy of my fellow clerks. However, after a few days of total bed rest his spirits and energy returned and he asked me to let him get up and around.In the 1950s, ever yb ody ‘knew’ that such patients, if they were to avoid permanent liver damage, must be kept at bed rest until their enlarged liver receded and their bilirubin and enzymes returned to normal. And if, after getting up and around, their enzymes rose again, back to bed they went. This conventional wisdom formed the basis for daily confrontations between an increasingly restless and resentful patient and an increasingly adamant and doom-predicting clinical clerk.We clinical clerks were expected to read material relevant to the care of our patients. I wanted to understand (for both of us) how letting him out of bed would exacerbate his pathophysiology. After exhausting several unhelpful texts, I turned to the journals. PubMed was decades away, and the National Library of Medicine hadn't yet begun to help the Armed Forces Medical Library with its Current List of the Medical Literature. Nonetheless, it directed me to a citation in the Journal of Clinical Investigation (back in the days when it was a real clinical j ou rnal) for: ‘The treatment of acute infectious hepatitis. Controlled studies of the effects of diet, rest, and physical reconditioning on the acute course of the disease and on the incidence of relapses and residual abnormalities.’1 Reading this paper not only changed my treatment plan for my patient, it forever changed my attitude toward conventional wisdom, uncovered my latent iconoclasm, and inaugurated my career inwhat I later labelled ‘clinical epidemiology’.The paper introduced me to Tom Chalmers, who quickly became my hero and, a decade later, my friend. Tom was a US Army gastroenterologist in the Korean War, and had become involved ina major outbreak of ‘infectious’ hepatitis among American recruits. The application of conventional wisdom on enforced bed rest was keeping affected soldiers in hospital for about two months and requiring another month's convalescence. Tom wrote: ‘This drain on military manpower, along with more recent [short-term metabolic] observations suggesting that strict bed rest might not be as essential as heretofore thought, emphasized the need for a controlled study to determine the safety of a more liberal regimen of rest and less prolonged hospitalization’.Employing what I increasingly came to recognize as ‘elegant simplicity’, Tom and his colleagues allocated soldiers who met pre-defined hepatitis criteria at random either to bed rest (continuously in bed, save for one trip daily to the bathroom and one trip to the shower weekly), or to be up and about as much as the patients wanted (with no effort made to control their activity save 1-hour rests after meals) throughout their hospital stay. The time to recovery (as judged by liver function testing) was indistinguishable between the comparison groups, and no recurrent jaundice was observed.Armed with this evidence, I convinced my supervisors to let me apologize to my patient and let him be up and about as much as he wished. He did, and his clinical course was uneventful.My subsequent ‘clinical course’ was far from uneventful. I became a ‘trouble-maker’, constantly questioning conventional therapeutic wisdom, and offending especially thesubspecialists when they pontificated (I thought) about how I ought to be treating my patients. I had a stormy time in obstetrics, where I questioned why patients with severe pre-eclampsia received intravenous morphine until their respirations fell below 12 per minute. I gained unfavourable notoriety on the medical ward, where I challenged a consultant's recommendation that I should ignore my patient's diastolic blood pressure of 125 mmHg ‘because it was essential for his brain perfusion’. And I deeply offended a professor of paediatrics by publicly correcting him on the number of human chromosomes (they had fallen from 48 to 46 the previous month!).Tom Chalmers, along with Ed Fries (who answered the question about whether diastolic blood pressure should be ignored) and Archie Cochrane, became my role models. Ten years after I discharged my hepatitis patient, armed with some book-learning and blessed with brilliant colleagues, I began to emulate these mentors by converting my passive skepticism into active inquiry, addressing such questions as: Why do you have to be a physician in order to provide first-contact primary care?5 Are the ‘experts’ corr ect that teaching people with raised blood pressure all about their illness really makes them more likely to take their medicine?6 Just because the aorto-coronary arterial bypass is good for ischaemic hearts, should we accept claims that extracranial–intracranial arterial bypass is good for ischaemic brains?7In the year that the paper by T om Chalmers and his colleagues was published, there were only 347 reports of randomized trials. Half a century later, about 50,000 reports of randomized trials were being published every year, with the total number of trial reports by then exceeding half amillion. I am proud to have contributed to this development, to the skepticism that drives it, and to the better informed treatment decisions and choices which have been made possible as a result.。

英语:英汉十大区别

英语:英汉十大区别

英语:英汉十大区别英语:英汉十大区别英语:英汉十大区别一、英语重结构,汉语重语义我国著名语言学家王力先生曾经说过:就句子的结构而论,西洋语言是法治的,中国语言是人治的。

(《中国语法理论》,《王力文集》第一卷,第35页,山东教育出版社,1984年)我们看一看下面的例子:children will play with dolls equipped with personality chips, computers with inbuilt (成为固定装置的,嵌入墙内的;内在的,固有的)personalities will be regarded as workmates rather than tools, relaxation will be in front of smell television, and digital age will have arrived。

译文:儿童将与装有个性芯片的玩具娃娃玩耍,具有个性内置的计算机将被视为工作伙伴而不是工具,人们将在气味电视前休闲,到这时数字时代就来到了。

这句英语是由四个独立句构成的并列句,前三个句子都用简单将来时,最后一个句子用的是将来完成时,句子之间的关系通过时态、逗号和并列连词and表示得一清二楚。

而汉语译文明显就是简单的叙述,至于句子之间的关系完全通过句子的语义表现出来:前三个句子可以看成是并列关系,最后一个句子则表示结果。

二、英语多长句,汉语多短句由于英语是"法治"的语言,只要结构上没有出现错误,许多意思往往可以放在一个长句中表达;汉语则正好相反,由于是"人治",语义通过字词直接表达,不同的意思往往通过不同的短句表达出来。

正是由于这个原因,考研英译汉试题几乎百分之百都是长而复杂的句子,而翻译成中文经常就成了许多短小的句子。

例如:interest in historical methods had arisen less through external challenge to the validity of history as an intellectual discipline (身心的锻炼,训练;纪律,风纪,命令服从;惩戒,惩罚;学科,科目)and more from internal quarrels among historians themselves.译文:人们对历史研究方法产生了兴趣,这与其说是因为外部对历史作为一门知识学科的有效性提出了挑战,还不如说是因为历史学家内部发生了争吵。

有效性(validity)是指研究结果的意义、准确性和可操作性。

它的
内容包括:普遍性(generality)、内部有效性(internal validity)、外部有效性(external validity)和内容有效性(content validity)。

普遍性(generality)是指研究发现的效果具有普遍性,因而可在多
个环境和情景中使用。

它有助于确定研究结果是否具有更广泛的应用价值。

内部有效性(internal validity)是指测量所检测变化是由研究设
计或者操作所造成的一种可靠性。

这意味着研究应该以最少的外部因素干
扰作为基准,以便研究结果不被其他外来变量的影响所偏离。

外部有效性(external validity)是指研究结果能否正确反映受试
者的实际行为和能力。

它涉及到样品取向、干扰因素、历史效应,以及其
他可能影响研究结果的变量。

内容有效性(content validity)是指从技术上来说,研究中使用的
测量工具能否有效地评估被试者的能力或行为。

其部分内容包括:可测量性、具体性、可行性、简洁性以及对受试者有吸引力等。

案例研究法

案例研究法
临旳诸如财政危机等,而是真正没有选
择旳管理情境,如生死危机等。
(二)执行阶段
1.搜集数据资料 案例研究旳数据起源涉及五种: ①文件资料 ②访谈 访谈旳类型主要有下列三种:
开放型访谈
半构造型访谈
构造型访谈
③观察 1.参加型观察 2.非参加型观察
④档案统计
⑤实物资料
研究者不只是一位被动旳 观察者,而是真正参加正
2.多案例研究 多案例研究(Multiple Cases)中,研究者首先要将每一种案例及其
主题作为独立旳整体进行进一步旳分析,即案例内分析(Within-Case Analysis)。依托于同一研究主旨,在彼此独立旳案例内分析旳基础上, 研究者将对全部案例进行归纳、总结,并得出抽象旳、精辟旳研究结论, 这一分析被称作为跨案例分析(Cross-Case Analysis )。 (例如生活质 量满意度研究,医学药物临床试验等等)
个别知识,引 出一般知识
旳推理
1.难以对发觉进行归纳:案例研究旳归纳不是统计性旳而是分 析性旳,这肯定使归纳带有一定旳随意性和主观性。
2.技术上旳局限和研究者旳偏见:案例研究没有一种原则化旳 数据分析措施,证据旳提出和数据旳解释带有可选择性,研究者在 乎见上旳分歧以及研究者旳其他偏见都会影响数据分析旳成果。
但是当理论命题不存在时,是个能够采用旳替代措施
(三)总结阶段(撰写报告 )
案例研究成果旳表述形式具有很大程度旳灵活性,并不存在原则 或统一旳报告格式。但在社会科学研究领域,经常会使用与案例研究 过程相匹配旳格式,从而将案例研究报告分为相对独立旳几种部分: ①背景描述;②特定问题、现象旳描述和分析;③分析与讨论;④小 结与提议。
2.选择案例
案例选择旳原则与研究旳对象和研究要回答旳问题有关,它拟定 了什么样旳属性能为案例研究带来有 意义旳数据。案例研究能够使用 一种案例或涉及多种案例。应以为单个案例研究能够用作确认或挑战 一种理论,也能够用作提出一种独特旳或极端旳案例。多案例研究旳 特点在于它涉及了两个分析阶段—— 案例内分析和跨案例分析。前者 是把每一种案例看成独立旳整体进行全方面旳分析 , 后者是在前者旳 基础上对全部旳案例进行统一旳抽象和归纳 , 进而得出更精辟旳描述 和更有力旳解释。

国外SCI研究针刺的两种临床随机对照试验方法的特点分析及评价

国外SCI研究针刺的两种临床随机对照试验方法的特点分析及评价

国外SCI研究针刺的两种临床随机对照试验方法的特点分析及评价项燕;李瑞【摘要】Objective : The goal of this research was to know the current state of foreign acupuncture through literatures collected by SCI, including methords they used and the existing problems. So we could provide domestic research workers with meaningful information about the development of foreign acupuncture research. Methods :In Web of Science and PubMed database,taking "trials and acupuncture" , "RCT and acupuncture" as title, we finally got 1581 literatures related to acupuncture which were published in Science Citation Index (SCI) Periodicals. We analyzed the characteristics of RCTs involved in the literatures and assess on them. Results Explanatory randomized controlled trials were used in most literatures. But the result of this kind of RCTs presented poor acupuncture outcome,with a view that acupuncture was not superior to sham acupuncture. While more and more western researchers affirmed that pragmatic randomized controlled trials were more suitable for acupuncture with complex interventions as its feature. The poor outcome that acupuncture was not superior to sham acupuncture had been the result of most SCI clinical studies. While the using of technique of fMRI which presents different mechanisms between acupuncture and sham acupuncture was a new trend in the process of improving the trials protocol, which without any doubt was good news for those promoters.Conclusion: The author of this article thinks that the foreign technicians do not really understand acupuncture with" smoothing meridians and collaterals and adjusting qi and blood" as its main effect is the fundamental reason for why the effect of acupuncture in SCI clinical trials is not ideal. For the internal researches, we suggest that ensuring whether to study the mechanism of acupuncture or the comparison clinical effects between acupuncture and other therapies is the most important in future studies. So the most appropriate trial protocol for clinical acupuncture study is available.%目的:为了解国外SCI针刺的发展、研究方法和研究水平及存在的问题,以便于国内针灸学术界及时掌握国际上高水准的针刺研究方法的发展动态.方法:检索web of science,PubMed两大数据库近5年来以“trials and acupuncture”、“RCT and acupuncture”为标题的所有被SCI收录的论文共1581篇,对其内容进行提取并分析试验设计特点和试验质量.结果:国外SCI大部分临床试验采用的是解释性随机对照试验,然其对于解释针刺组疗效优于假针对照组疗效并不理想,也不利国外针刺研究的进一步发展;而实用性随机对照试验在方法学上更适合于复杂干预的针刺临床研究.对于国外SCI的针刺临床试验研究结果显示针刺疗效与假针疗效无差异.结论:通过数据分析,认为国外针刺临床研究中操作者未得针刺“通经络、调气血”之真义才是导致临床研究中针刺疗效不显著的根本原因所在.对于国内研究者来说,今后在选择临床试验设计方案时,应有一个明确的研究目标,无论是选择哪种研究方法,ERCT还是PRCT作为设计方案,重要的是要有一个明确的研究目标,明确研究的目的是探讨针刺的作用机制或针刺特异性还是研究针刺与其他疗法的疗效对比,从而选择最恰当的研究方案.【期刊名称】《针灸临床杂志》【年(卷),期】2012(028)009【总页数】5页(P9-13)【关键词】SCI;针灸;随机对照试验【作者】项燕;李瑞【作者单位】北京中医药大学,北京100029;北京中医药大学,北京100029【正文语种】中文【中图分类】R245-0针刺疗法是中国传统医学的重要组成部分,蕴含着中华民族特有的精神、思维和文化精华。

internal and external validity内部有效性和外部有效性

internal and external validity内部有效性和外部有效性

CHAPTER 8: INTERNAL and EXTERNAL VALIDITYAn experiment is internally valid if there are no confounds.... that is, the only reason why the groups are different (with respect to the DV) is “actually and only” because of differences in the IVEIGHT THREATS TO INTERNAL VALIDITYall of the following are a potential source of confounds:1. HistoryCan be a problem in a repeated measures (within subjects) design whereeach participant is tested in each group.A history effect is present when an event (external to participants) occurs:a) Between presentations of the levels of the IVe.g. IV = day of the week: between taking a quiz on Tuesdayand a quiz on Thursday, the campus “shuts down” on Wedwhen a student goes on the rampage (must of gotten his statstest back)orb) From pre-test to post-test with the IV presented in betweene.g. students take a questionnaire on assertiveness > thenreceive assertiveness training > then take the assertivenessquestionnaire again. What if something happens between thepre-test and post-test during the time the IV is presented (e.g.US goes to war with Canada)2. MaturationSystematic, time-related changes in the participants that occur betweenpresentations of the levels of the IV (or while the IV is being presented) ina repeated (within subjects) design (e.g. participants may be growingboard, anxious, hungry, tired etc... they are also getting older)Beware of a maturation effect especially if testing takes place over a longtime, or the task is very difficult, etc...3. Testingchanges in the DV occur simply because the DV was measured (i.e. notbecause of the particular level of the IV).Examplesi. The Hawthorn effect (also called reactance or reactivity effect)Elton Mayo's Hawthorne StudiesThe Hawthorne Studies (or Hawthorne Experiments) were conducted from1927 to 1932 at the Western Electric Hawthorne Works in Cicero, Illinois(a suburb of Chicago), where professor Elton Mayo examined productivityand work conditions. Elton Mayo started these experiments by examiningthe physical and environmental influences of the workplace (e.g.brightness of lights, humidity) and later, moved into the psychologicalaspects (e.g. breaks, group pressure, working hours, managerialleadership).The Hawthorne EffectIn essence, the Hawthorne Effect can be summarized as "Individualbehaviors may be altered because they know they are being studied."Elton Mayo's experiments showed an increase in worker productivity wasproduced by the psychological stimulus of being singled out, involved,and made to feel important.Additionally, the act of measurement, itself, impacts the results of themeasurement. Just as dipping a thermometer into a vial of liquid can affectthe temperature of the liquid being measured, the act of collecting data,where none was collected before creates a situation that didn't exist before,thereby affecting the results. Another example is measuring attitudestoward discrimination. If the survey is not “disguised” well, participantscould alter their responses (the DV) to provide only socially acceptableresponsesYou can avoid this problem by using non-reactive measures. Forexample, measure the DV in such a way that participants do not knowwhat’s being measured, or perhaps even that they are being observed.(One way mirrors, hidden cameras, deception)ii. Practice effects (or fatigue)Changes in the DV occur simply because of practice with the task(i.e. has nothing to do with the particular levels of the IV)... note thatthis effect is only a factor in repeated designs.E.g. if you take the GRE several times, you can expect your scoreto increase a little each time…it’s not that you know more, you justhave more practice and you are more familiar & comfortable withthe procedure4. Instrumentation effects and human errorValues of the DV change because of faulty equipment, the human scorergets tired etc... That is, changes in the DV which result fromchanges/errors in the recording device (whether synthetic or human)Control by testing a few participants from each group all around the same time. NEVER test all of group A, then test all of group B, then all of group C…a HUGE faux pas!Check your instruments/equipment before testing each day5. Statistical RegressionCan occur in repeated measure designs when people score eitherextremely high or extremely low. You could see regression toward themean. The next time you measure them, there will be a tendency for their scores to move in the direction toward the mean... This is a confoundbecause you will not know if the DV changed because of the IV, orbecause of regression toward the mean.6. SelectionThis is a problem that could arise when using an IV that is a classification (or subject) variable. Examples include: gender, SES, academic major,mental diagnosis… There are certainly pre-existing differences betweenthe levels (categories) of each factor. If you do see a difference betweenthe levels, how do you know if the IV produced the difference vs. the pre-existing differences which are only tangentally related to the IVe.g. Does watching American Idol increase singing in the shower? Tofind out, you record how long American Idol fans sing in the shower vsnon-American Idol fans. However, American Idol fans are probablydifferent from non-fans in other respects eg. AI fans are more intelligent!7. Mortalityrefers to attrition due to death and “no shows”If mortality occurs in one condition more than the other conditions, thenyou have a problem, specifically, a confoundThe “survivors” in the group that w as hit particularly hard are probably verydifferent from the subjects in the other groups. If you now see a differencebetween the groups, you won’t know if it’s because of the IV or somethingparticular to that one group of survivorsEven if mortality is approx the same for each group, you still have aproblem. To what extent do the survivors represent the population youhad originally targeted? I.e. you have a problem with external validity8. Diffusion or imitation of treatmentParticipants in one treatment group become familiar with the treatment ofanother group. They then either copy that treatment or are just otherwiseaffected by what they have learned. As such, they are no longer “naive”and this changes their behavior. This will minimize or mask completelythe difference between your groups in an experiment.We try to prevent this from happening by asking people to refrain fromtalking about the experiment with any other participant until the experimentis over.Interactions with selectionOccur when one or more of the effects discussed above (e.g. history, maturation, mortality, testing, instrumentation etc) are systematically different between the different levels of the classification IVE.g. cross-cultural research is prone to a selection x history effect. That is,different cultures differ not only by culture, but also by their historical experiencesPROTECTING INTERNAL VALIDITYThese actions need to be taken before you run the experiment.First, you must sit down and think about all the potential confounds. Askyourself, “what could go wrong”.Second, implement one or more of the control techniques discussed in chapters6 and 7. (e.g. balance, random assignment to group, hold the EV constant etc…)Third, carefully follow one of the standardized experimental designs, to bediscussed in chapters 10, 11, 12. (e.g. repeated measures t-tests, mixedANOVAs)Fourth, have a knowledgeable person(s) review your proposal before youconduct the experiment.The book says that statistics do not control/eliminate confounds, nor detect them.This is mainly true, but note exceptions:Analysis of co-variance can control for potential confoundsChi squares can help detect a potential confound by seeing if anextraneous variable is evenly distributed across the different levels of theIVThe extent to which your results apply to populations/situations/times/environments different from those in your experiment… concept of generalizabilityDifferent types of generalizationPopulation generalization: the extent to which your results generalize topeople/animals beyond just the participants you tested.Environmental: the extent to which your results generalize to situations orenvironment beyond those used in the current experiment Temporal: the extent to which your findings apply at all times, not just thespecific time/season your study was conducted.NOTE: in all cases, the lack of generalization could in and of itself be VERYinteresting and could yield vital clues about human/animal behavior Relationship between internal validity and external validityRemember this relationship from the previous chapter: as one goes up, the other goes down… as a general rule…As we implement more and more controls to reduce confounds (i.e. increaseinternal validity) we are making the experiment more and more artificial andthereby it’s generalizability (external validity) suffers.An exception would be in reference to specific control techniquese.g. the balance technique would allow for more generalizability thanwould the eliminate or hold constant techniquesRelationship between within group variability, power, and external validity Recall that one way to increase power is to test homogeneous groups. But, inthe real world, people are not homogeneous. So, by testing homogeneousgroups, our results may not generalize well to the real world.FOUR THREATS TO EXTERNAL VALIDITY BASED ON METHODSOften, the design of our experiment threatens its generalizability1. Interaction of testing and treatmentIn a pre-test, post-test design (also called a before-after design), the pre-test may sensitize people to the treatment yet to come. Since pre-testingdoes not occur in the real world, our results may fail to generalize wellYou can estimate the effect your pre-test has by adding another group:those who only get the post-test2. Interaction of selection and treatmentThis occurs when the groups of participants you test are so unique, yourresults do not generalize beyond them.3. Reactive arrangementsWhen people know they are part of an experiment, they typically changetheir behavior no matter what the IV is that they are exposed to (theHawthorne effect). This means that our results may not generalize to thereal world where people are not part of an experiment and whose behavioris not thus affectedDemand Characteristics present in reactive treatmentsRecall that these are just about anything (other than what theexperimenter says or does) that participants use to figure out thehypothesis or how they should behave. You cannot eliminate demandcharacteristics in an experiment where people know they are part of thestudy. Since the DC’s change participants’ behavior, and these DC’s arenot present in the real world, your results may not generalize well to thereal world. The only way to completely remove DC’s in a study is if youuse naturalistic observation4. Multiple Treatment InterfaceThese occur in repeated designs where the same people are tested ineach group or condition. It’s possible that the effect you observe ispresent only when people are exposed to this constellation of treatments.That is, in the real world you would not observe the same effect of aspecific treatment because it was not accompanied by the othertreatments.FIVE THREATS TO EXTERNAL VALIDITY BASED ON PARTICIPANTS Limited types of population tested (animal)Especially in animal research, we tend to test mostly rats (and specificbreeds at that). To what extent will the results generalize to other species,including humans?Limited types of population tested (human)In human research, we tend to use convenience sampling and test mostlycollege students. To what extent do college students represent thegeneral population? To the extent that they don’t, our external validitysuffers.Gender BiasFor many reasons, some of which persist today, men were studied morethan women in psychological and medical research. To what extent canyou generalize from research conducted on men to women (or vise versafor that matter)?Racial BiasSame idea as above. If your research does not include certain racialgroups, you must exercise caution when trying to generalize to them.Cultural Bias (ethnocentric research)If you study American culture in America, your results can only beassumed to generalize to American culture in AmericaFour goals of research that do not stress external validity1. Finding out if something CAN happen, not when if it usually happens2. Finding out if a real world phenomenon occurs in the lab3. Finding out if something occurs in the lab’s unnatural settings can strengthenthe validity of the phenomenon4. Studying a phenomenon in the lab that doesn’t have a real world counterpart According to Smith & Davis, internal validity is essential for an experiment, whereas external validity is not.Replication with extension can be used to establish the validity of the finding and its external validityOnce an effect is demonstrated under one set of circumstances (testingenvironment, time, participants), you can replicate the finding by changing one or more of these variables. It is advisable to change only one thing at a time. Why?。

医学科研中的偏倚及其控制课件

医学科研中的偏倚及其控制课件
常表现为研究人群的结论不能推广到目 标人群乃至更大的总体人群,影响内部真实 性和外部真实性。
1. 入院率偏倚(admission rate bias)
也称伯克森偏倚(Berkson’s bias) , 是指在进行病例对照研究,临床防治试验、 预后判断等研究时,利用医院就诊或住院 病人作为研究对象时,由于入院率或就诊 机会不同而导致的偏倚称为入院率偏倚。
结论:以医院病例作为样本所得观察结果,高血脂是 恶性黑素瘤的保护因素,而骨折则是一危险因素。
设hA为A病(研究疾病)的入院率 hB为B病(对照疾病)的入院率 hC为C因素(研究因素)的入院率
当hA = hB时,不发生入院率偏倚; hC =0时,也不发生入院率偏倚。
当hA > hB,且hC > 0时,发生入院率偏倚,它使 OR值减小,偏倚程度的大小取决于hC的大小, hC 越小,偏倚程度越小。 当hA < hB,且hC > 0时,也发生入院率偏倚,它 使OR值增加,偏倚程度的大小也取决于hC的大小。
亦称揭露伪装偏倚,指某因素与某疾病在病因学 上虽无关联,但由于该因素的存在而引起该疾病症状 或体症的出现,从而使患者及早就医,接受多种检查, 导致该人群较高的检出率,以致得出该因素与该疾病 相关联的错误结论。

对照
1. 入院率偏倚(admission rate bias)
控制: (1)进行以人群为基础的病例对照研究 (2)若仍采用以医院为基础的研究,最好 进行多中心合作研究
2. 现患病例-新发病例偏倚
(prevalence-incidence bias)
也称奈曼偏倚(Neyman bias),凡因现患 病例与新病例的构成不同,只调查典型病例 或者现患病例的暴露情况,致使调查结果出 现的系统误差都属于这类偏倚。

ReliabilityandValidityWhat

ReliabilityandValidityWhat

Reliability and Validity: What's the Difference?ReliabilityDefinition: Reliability is the consistency of your measurement, or the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects. In short, it is the repeatability of your measurement. A measure is considered reliable if a person's score on the same test given twice is similar. It is important to remember that reliability is not measured, it is estimated.There are two ways that reliability is usually estimated: test/retest and internal consistency.Test/RetestTest/retest is the more conservative method to estimate reliability. Simply put, the idea behindtest/retest is that you should get the same score on test 1 as you do on test 2. The three main components to this method are as follows:1.) implement your measurement instrument at two separate times for each subject;2). compute the correlation between the two separate measurements; and3) assume there is no change in the underlying condition (or trait you are trying to measure)between test 1 and test 2.Internal ConsistencyInternal consistency estimates reliability by grouping questions in a questionnaire that measure the same concept. For example, you could write two sets of three questions that measure the same concept (say class participation) and after collecting the responses, run a correlation between those two groups of three questions to determine if your instrument is reliably measuring that concept. One common way of computing correlation values among the questions on your instruments is by using Cronbach's Alpha. In short, Cronbach's alpha splits all the questions on your instrument every possible way and computes correlation values for them all (we use a computer program for this part). In the end, your computer output generates one number for Cronbach's alpha - and just like a correlation coefficient, the closer it is to one, the higher the reliability estimate of your instrument. Cronbach's alpha is a less conservative estimate of reliability than test/retest.The primary difference between test/retest and internal consistency estimates of reliability is that test/retest involves two administrations of the measurement instrument, whereas the internal consistency method involves only one administration of that instrument.ValidityDefinition:Validity is the strength of our conclusions, inferences or propositions. More formally, Cook and Campbell (1979) define it as the "best available approximation to the truth or falsity of a given inference, proposition or conclusion." In short, were we right? Let's look at a simple example. Say we are studying the effect of strict attendance policies on class participation. In our case, we saw that class participation did increase after the policy was established. Each type of validitywould highlight a different aspect of the relationship between our treatment (strict attendance policy) and our observed outcome (increased class participation).Types of Validity:There are four types of validity commonly examined in social research.1. Conclusion validity asks is there a relationship between the program and the observedoutcome? Or, in our example, is there a connection between the attendance policy and theincreased participation we saw?2. Internal Validity asks if there is a relationship between the program and the outcome wesaw, is it a causal relationship? For example, did the attendance policy cause classparticipation to increase?3. Construct validity is the hardest to understand in my opinion. It asks if there is there arelationship between how I operationalized my concepts in this study to the actual causalrelationship I'm trying to study/? Or in our example, did our treatment (attendance policy)reflect the construct of attendance, and did our measured outcome - increased classparticipation - reflect the construct of participation? Overall, we are trying to generalize our conceptualized treatment and outcomes to broader constructs of the same concepts.4. External validity refers to our ability to generalize the results of our study to other settings.In our example, could we generalize our results to other classrooms?Threats To Internal ValidityThere are three main types of threats to internal validity - single group, multiple group and social interaction threats.Single Group Threats apply when you are studying a single group receiving a program or treatment. Thus, all of these threats can be greatly reduced by adding a control group that is comparable to your program group to your study.A History Threat occurs when an historical event affects your program group such that it causes the outcome you observe (rather than your treatment being the cause). In our earlier example, this would mean that the stricter attendance policy did not cause an increase in class participation, but rather, the expulsion of several students due to low participation from school impacted your program group such that they increased their participation as a result.A Maturation Threat to internal validity occurs when standard events over the course of time cause your outcome. For example, if by chance, the students who participated in your study on class participation all "grew up" naturally and realized that class participation increased their learning (how likely is that?) - that could be the cause of your increased participation, not the stricter attendance policy.A Testing Threat to internal validity is simply when the act of taking a pre-test affects how that group does on the post-test. For example, if in your study of class participation, you measured class participation prior to implementing your new attendance policy, and students became forewarned that there was about to be an emphasis on participation, they may increase it simply as a result of involvement in the pretest measure - and thus, your outcome could be a result of a testing threat - not your treatment.An Instrumentation Threat to internal validity could occur if the effect of increased participation could be due to the way in which that pretest was implemented.A Mortality Threat to internal validity occurs when subjects drop out of your study, and this leads to an inflated measure of your effect. For example, if as a result of a stricter attendance policy, most students drop out of a class, leaving only those more serious students in the class (those who would participate at a high level naturally) - this could mean your effect is overestimated and suffering from a mortality threat.The last single group threat to internal validity is a Regression Threat. This is the most intimating of them all (just its name alone makes one panic). Don't panic. Simply put, a regression threat means that there is a tendency for the sample (those students you study for example) to score close to the average (or mean) of a larger population from the pretest to the posttest. This is a common occurrence, and will happen between almost any two variables that you take two measures of. Because it is common, it is easily remedied through either the inclusion of a control group or through a carefully designed research plan (this is discussed later). For a great discussion of regression threats, go to Bill Trochim's Center for Social Research Methods.In sum, these single group threats must be addressed in your research for it to remain credible. One primary way to accomplish this is to include a control group comparable to your program group. This however, does not solve all our problems, as I'll now highlight the multiple group threats to internal validity.Multiple Group Threats to internal validity involve the comparability of the two groups in your study, and whether or not any other factor other than your treatment causes the outcome. They also (conveniently) mirror the single group threats to internal validity.A Selection-History threat occurs when an event occurring between the pre and post test affects the two groups differently.A Selection-Maturation threat occurs when there are different rates of growth between the two groups between the pre and post test.Selection-Testing threat is the result of the different effect from taking tests between the two groups.A Selection-Instrumentation threat occurs when the test implementation affects the groups differently between the pre and post test.A Selection-Mortality Threat occurs when there are different rates of dropout between the groups which leads to you detecting an effect that may not actually occur.Finally, a Selection-Regression threat occurs when the two groups regress towards the mean at different rates.Okay, so know that you have dragged yourself through these extensive lists of threats to validity - you're wondering how to make sense of it all. How do we minimize these threats without going insane in the process? The best advice I've been given is to use two groups when possible, and if you do, make sure they are as comparable as is humanly possible. Whether you conduct a randomized experiment or a non-random study --> YOUR GROUPS MUST BE AS EQUIVALENT AS POSSIBLE! This is the best way to strengthen the internal validity of your research.The last type of threat to discuss involves the social pressures in the research context that can impact your results. These are known as social interaction threats to internal validity.Diffusion or "Imitation of Treatment occurs when the comparison group learns about the program group and imitates them, which will lead to an equalization of outcomes between the groups (you will not see an effect as easily).Compensatory Rivalry means that the comparison group develops a competitive attitude towards the program group, and this also makes it harder to detect an effect due to your treatment rather than the comparison groups reaction to the program group.Resentful Demoralization is a threat to internal validity that exaggerates the posttest differences between the two groups. This is because the comparison group (upon learning of the program group) gets discouraged and no longer tries to achieve on their own.Compensatory Equalization of Treatment is the only threat that is a result of the actions of the research staff - it occurs when the staff begins to compensate the comparison group to be "fair" in their opinion, and this leads to an equalization between the groups and makes it harder to detect an effect due to your program.Threats to Construct ValidityI know, I know - you're thinking - no I just can't go on. Let's take a deep breath and I'll remind you what construct validity is, and then we'll look at the threats to it one at a time. OK? OK.Constuct validity is the degree to which inferences we have made from our study can be generalized to the concepts underlying our program in the first place. For example, if we are measuring self-esteem as an outcome, can our definition (operationalization) of that term in our study be generalized to the rest of the world's concept of self-esteem?Ok, let's address the threats to construct validity slowly - don't be intimidated by their lengthy academic names - I'll provide an English translation.Inadequate Preoperational Explication of Constructs simply means we did not define our concepts very well before we measured them or implemented our treatment. The solution? Define your concepts well before proceeding to the measurement phase of your study.Mono-operation bias simply means we only used one version of our independent variable (our program or treatment) in our study, and hence, limit the breadth of our study's results. The solution? Try to implement multiple versions of your program to increase your study's utility.Mono-method bias simply put, means that you only used one measure or observation of an important concept, which in the end, reduces the evidence that your measure is a valid one. The solution? Implement multiple measures of key concepts and do pilot studies to try to demonstrate that your measures are valid.Interaction of Testing and Treatment occurs when the testing in combination with the treatment produces an effect. Thus you have inadequately defined your "treatment," as testing becomes part of it due to its influence on the outcome. The solution? Label your treatment accurately.Interaction of Different Treatments means that it was a combination of our treatment and other things that brought about the effect. For example, if you were studying the ability of Tylenol to reduce headaches and in actuality it was a combination of Tylenol and Advil or Tyle nol and exercise that reduced headaches -- you would have an interaction of different treatments threatening your construct validity.Restricted Generalizability Across Constructs simply put, means that there were some unanticipated effects from your program, that may make it difficult to say your program was effective.Confounding Constructs occurs when you are unable to detect an effect from your program because you may have mislabeled your constructs or because the level of your treatment wasn't enough to cause an effect.As with internal validity, there are a few social threats to construct validity also. These include:1. Hypothesis Guessing: when participants base their behavior on what they think yourstudy is about - so your outcome is really not due solely to the program - but also to theparticipants' reaction to you and your study.2.Evaluator Apprehension: When participant's are fearful of your study to the point that itinfluences the treatment effect you detect.3.Experimenter Expectancies: when researcher reactions shape the participant's responses -so you mislabel the treatment effect you see as due to the program when it is more likely due to the researchers behavior.See, that wasn't so bad. We broke things down and attacked them one at a time. You may be wondering why I haven't given you along list of threats to conclusion and external validity - the simple answer is it seems as if the more critical threats involve internal and construct validity. And, the means by which we improve conclusion and external validity will be highlighted in the section on Strengthening Your Analysis.SummaryThe real difference between reliability and validity is mostly a matter of definition. Reliability estimates the consistency of your measurement, or more simply the degree to which an instrument measures the same way each time it is used in under the same conditions with the same subjects. Validity, on the other hand, involves the degree to which your are measuring what you are supposed to, more simply, the accuracy of your measurement. It is my belief that validity is more important than reliability because if an instrument does not accurately measure what it is supposed to, there is no reason to use it even if it measures consistently (reliably).。

rct评价降级标准

rct评价降级标准

rct评价降级标准RCT(Randomized Controlled Trial)是一种高品质的实验研究设计,旨在评估一种干预措施的效果。

为了保证RCT研究的科学性和可靠性,评价降级标准是必不可少的。

下面将介绍一些相关的参考内容,以帮助研究人员进行评价降级。

1. 方法偏倚(Bias)RCT研究中常见的方法偏倚包括选择偏倚、信息偏倚、记忆偏倚等。

评价降级时,可以根据Cochrane Handbook for Systematic Reviews of Interventions中推荐的工具,例如Cochrane Risk of Bias Tool来评估RCT研究的偏倚程度。

通过对研究方法的严谨性进行评估,可以降低研究结果的不确定性。

2. 样本量(Sample Size)样本量是评价RCT研究的重要指标之一,它直接影响研究结果的可靠性和推广能力。

通常来说,样本量越大,研究结果的置信度越高。

因此,在评价降级时,可以参考Cochrane Handbook for Systematic Reviews of Interventions中推荐的计算样本量的方法,以评估研究是否具备足够的统计功效。

3. 外部效度(External Validity)外部效度指的是RCT研究结果在不同研究场景下的推广性。

评价降级时,可以考虑RCT研究中的参与者是否代表了目标人群,干预措施是否适用于实际临床实践。

此外,还可以参考公开发表的同类型研究,比较其研究人群的特征、干预措施的设置、结果的一致性等,以评估RCT研究的外部效度。

4. 结果的一致性(Consistency)结果的一致性是衡量RCT研究可靠性与有效性的重要指标之一。

评价降级时,可以考虑对研究结果进行Meta分析,检查不同研究之间的一致性。

一致的结果可以提高RCT研究的证据级别,反之则降低其证据级别。

5. 转化到临床实践的可行性(Feasibility)RCT研究的可行性评估是评价降级的关键之一。

Do the who, where, what & when of our study represent
what we intended want to study?
Measurement Validity
• Task/Stimulus
• Participant Selection -- Population Validity
Bivariate RH:s, Research Designs and Validity...
A RH: is a guess about the relationships between behaviors In order to test our RH: we have to decide on a research design, sample participants, collect data, statistically analyze those data and make a final conclusion about whether or not our results support our RH:
When we are all done, we want our conclusion to be “valid”
Validity … has lots of types, definitions & procedures but basically it means … Accuracy or Correctness
Internal Validity
– is it correct to give a causal interpretation to the relationship we found between the variables/behaviors ?
Statistical Conclusion Validity
the research “design” -- all the choices of how we will run the study
Internal validity
External validity
• control
• generalizability
• causal interpretability
• did we get non-representative results “by chance” ? • did we get non-representative results because of external, measurement or
