Systematic Review and Meta analysis - All you ever need to know
 
01:02:16
Meta analysis is a very common way of bringing together data to help us decide which treatments might be best. BUT, you have to take care when interpreting them - there's a lot more to it than just looking which side of the line the little black diamond is on! How do you construct a search for a systematic review?Can you trust the result of a meta analysis? How do you know if it has been done well? How to recognise different kinds of bias, how to interpret a forest plot, and funnel plot and a bubble plot. What is the I squared statistic and what does it tell you about the data and how much to trust the result? These and many more things to do with these common but complex analyses is explained by Brett Doleman, statistical guru!

Presentiment: "Feeling" the Future

Over the past 45 years, researchers have amassed a sizeable body of literature attesting to the human ability to "sense" things in the future.

What does META-ANALYSIS mean? META-ANALYSIS meaning - META-ANALYSIS definition - META-ANALYSIS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The basic tenet of a meta-analysis is that there is a common truth behind all conceptually similar scientific studies, but which has been measured with a certain error within individual studies. The aim in meta-analysis then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. In essence, all existing methods yield a weighted average from the results of the individual studies and what differs is the manner in which these weights are allocated and also the manner in which the uncertainty is computed around the point estimate thus generated. In addition to providing an estimate of the unknown common truth, meta-analysis has the capacity to contrast results from different studies and identify patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies. Meta-analysis can be thought of as "conducting research about previous research." Meta-analysis can only proceed if we are able to identify a common statistical measure that is shared among studies, called the effect size, which has a standard error so that we can proceed with computing a weighted average of that common measure. Such weighting usually takes into consideration the sample sizes of the individual studies, although it can also include other factors, such as study quality. A key benefit of this approach is the aggregation of information leading to a higher statistical power and more robust point estimate than is possible from the measure derived from any individual study. However, in performing a meta-analysis, an investigator must make choices many of which can affect its results, including deciding how to search for studies, selecting studies based on a set of objective criteria, dealing with incomplete data, analyzing the data, and accounting for or choosing not to account for publication bias. Meta-analyses are often, but not always, important components of a systematic review procedure. For instance, a meta-analysis may be conducted on several clinical trials of a medical treatment, in an effort to obtain a better understanding of how well the treatment works. Here it is convenient to follow the terminology used by the Cochrane Collaboration, and use "meta-analysis" to refer to statistical methods of combining evidence, leaving other aspects of 'research synthesis' or 'evidence synthesis', such as combining information from qualitative studies, for the more general context of systematic reviews.

A Meta-analysis of the Relationship between Psychological Disengagement Mechanisms and Self-esteem
 
09:02
When individuals feel disadvantaged or anticipate a threat to their self-esteem (because of their group membership, for example), they may psychologically disengage their self-esteem from a domain as a means of self-protection. This can be achieved via two mechanisms: discounting the validity of feedback received; and devaluing the importance of the domain for the self-concept. The study of psychological disengagement and the association between discounting and devaluing and self-esteem has generated unstable results. This meta-analysis conducted using 30 distinct samples sought to understand the association between psychological disengagement and self-esteem. A few key moderators were evaluated in order to attempt to explain the variance observed in the results of previous studies: the domain in which the study was conducted (school or work domain); the status of the group (minority or majority status); and the status of the domain (low or high). Results show that discounting and devaluing are negatively linked to self-esteem and the domain type seems to moderate these two links. Group status and domain status moderated some relationships for discounting and devaluing, respectively. These results suggest that psychological disengagement's association with self-esteem is not uniform. Theoretical implications and future directions of research are discussed.

APA Style Journal Article Reporting Standards
 
04:01
As part of its promotion of greater transparency and the assessment of rigor in psychological science, the American Psychological Association has released new Journal Article Reporting Standards for researchers seeking to publish in scholarly journals. The standards are specific to psychological research and offer guidelines on the information needed in a research article to ensure that the elements included are comprehensible and that the study can be replicated. The new standards: - Recommend the division of hypotheses, analyses and conclusions into primary, secondary and exploratory groupings to allow for a full understanding of quantitative analyses presented in a manuscript and enhance reproducibility. - Offer modules for authors reporting on N-of-1 design, replication, clinical trials, longitudinal studies and observational studies, as well as the analytic methods structural equation modeling and Bayesian analysis. - Address the plurality of inquiry traditions, methods and goals, providing guidance on material to include across diverse qualitative research methods. - Provide standards for reporting research using mixed-method designs, drawing on both qualitative and quantitative standards. For more information: “Journal Article Reporting Standards for Quantitative Research in Psychology: The APA Publications and Communications Board Task Force Report” - http://www.apa.org/pubs/journals/releases/amp-amp0000151.pdf “Journal Article Reporting Standards for Qualitative Primary, Qualitative Meta-Analytic, and Mixed Methods Research in Psychology: The APA Publications and Communications Board Task Force Report” - http://www.apa.org/pubs/journals/releases/amp-amp0000151.pdf "Editorial: Journal Article Reporting Standards” - http://www.apa.org/pubs/journals/releases/amp-amp0000263.pdf __ The American Psychological Association is the leading scientific and professional organization representing psychology in the United States, with more than 115,700 researchers, educators, clinicians, consultants and students as its members.

Randomized Controlled Trials (RCTs)
 
08:56
A randomized controlled trial (RCT) is an experimental form of impact evaluation in which the population receiving the programme or policy intervention is chosen at random from the eligible population, and a control group is also chosen at random from the same eligible population. It tests the extent to which specific, planned impacts are being achieved. The distinguishing feature of an RCT is the random assignment of units (e.g. people, schools, villages, etc.) to the intervention or control groups. One of its strengths is that it provides a very powerful response to questions of causality, helping evaluators and programme implementers to know that what is being achieved is as a result of the intervention and not anything else. This video summarizes the key features of an RCT. For details, please read Brief 7 at http://www.unicef-irc.org/KM/IE/

(This webinar was originally recorded Oct. 22) This webinar reviews the current guidelines for the treatment of posttraumatic stress disorder (PTSD) at all points in the treatment continuum. It highlights the significant areas where current major guidelines (VA/DoD, WHO, NICE, APA and ISTSS) are not in agreement including medications versus therapy, individual medications and behavioral therapies. The presenter shares variances in the evaluation of data that resulted in these differences and reviews an evaluation of current studies in the form of four meta-analyses looking at more than 17,000 citations for best evidence-based treatment. Webinar participants learn to: -- Restate the current guidelines for the treatment of PTSD -- Differentiate between the current evidence for medication versus behavioral therapy as evidence-based treatment -- Identify medications with the best evidence supporting their use for PTSD -- Compare behavioral therapies with the best evidence supporting their use for PTSD DCoE hosts monthly webinars to provide information and facilitate discussion on a variety of topics related to psychological health and traumatic brain injury.

This presentation, by Patrick Forscher of the University of Wisconsin, is titled "A Meta-Analysis of Interventions to Change Implicit Bias." Implicit bias has been implicated in a number of social problems, ranging from racial disparities to depression, leading to widespread calls to develop effective implicit bias interventions. However, despite two decades of effort, researchers have little knowledge of the relative effectiveness or generalizability of these interventions. To address this gap, researchers conducted a multivariate network metaanalysis of 220 randomized interventions to change implicit bias and, where available, explicit bias and behavior. Interventions that were coded into different categories based on their presumed mechanisms of change had differential effects on implicit bias. Moreover, interventions that were effective in changing implicit bias, in particular those based on the direct change of the activation of associations, were not necessarily effective in changing behavior. The results provide structure to implicit bias research and suggest that interventions that affect implicit bias will not necessarily have generalized effects on behavior in applied settings.

Каждому из нас приходится оказываться в ситуации, когда мы скучаем. Скука отравляет наше существование и мы стараемся сбежать от неё. Почему так? Потому что скука - неприятной чувство, оно нам не нравится из-за дискомфорта, а мало кому нравится оставаться там, где дискомфортно. Но давайте задумаемся - разве всегда дискомфорт является чем-то плохим?Разве "дискомфорт" и "плохо" являются синонимами? Например, горькое лекартсво однозначно дискомфортно. Но оно не плохое, а очень даже хорошее, полезное. Так и со скукой. Она нам неприятна, но, как оказывается, очень полезна для нас. Скука выполняет много функций и если знать, как её использовать, можно получить очень много полезных штук в своей жизни. Как раз о том, зачем на нужна скука и как её можно использовать, я и рассказываю в сегодняшнем видео.

What are Research Methods? (Basics for A Level Psychology)

This very short video highlights the importance of understanding what research method the investigator is using. That could be: Experiment Correlation Observation Self-Report Meta-anaylysis Case Study Content Analysis Once you know the research method you will be able to determine what next to look for, eg, if it's an experiment you would identify the IV and DV etc. If you would like to test your research methods skills for the exams, you can try this unofficial exam paper: https://www.tes.com/teaching-resource/unofficial-exam-paper-and-mark-scheme-for-research-methods-aqa-a-level-psychology-48-marks-1st-set-11847223 If you have any questions, please get in touch via YouTube or Twitter @blonde_pretzel Thanks

The New Statistics: Research Integrity & the New Statistics (Workshop Part 2)
 
29:43
Featuring Geoff Cumming La Trobe University, Australia Leading scholars in psychology and other disciplines are striving to help scientists enhance the way they conduct, analyze, and report their research. They advocate the use of “the new statistics,”— effect sizes, confidence intervals, and meta-analysis. APS’ flagship journal, Psychological Science, has been inviting authors to use the “new statistics” as part of a comprehensive effort to enhance research methodology. In this workshop, Geoff Cumming, a leading expert in new statistics, explains why all these changes are necessary, and suggests how psychological scientists can implement them. The workshop was recorded at the 2014 APS Annual Convention in San Francisco, and is presented here as six video segments. It makes extensive use of interactive simulations to illustrate concepts, and provides a wealth of practical guidance. Part 2 Includes: • The replicability crisis in many scientific disciplines • The over-reliance on p = .05 as an underlying cause of the replicability problem • Solutions being developed to enhance research integrity, including: • pre-registration of studies • full reporting of all procedures and data • encouragement of replication • The need for open science.
