A Brief Guide to Questionnaire Development. Robert Frary, Virginia Tech. This website is cited in Category: Survey design. Excerpt: Most people have responded to so many questionnaires in their lives that they have little concern when it becomes necessary to construct one of their own. Unfortunately the results are often unsatisfactory. These problems are sufficiently prevalent that numerous books and journal articles have been written addressing them (e.g., see Dillman, 1978). Also, various educational and proprietary organizations regularly offer workshops in questionnaire development. Therefore, the brief exposition that follows is intended only to identify some of the more prevalent problems in questionnaire development and to suggest ways of avoiding them. This paper does not cover the development of inventories designed to measure psychological constructs, which would require a deeper discussion of psychometric theory than is feasible here. Instead, the focus will be on questionnaires designed to collect factual information and opinions. This website was last verified on 2008-01-14. URL: www.testscoring.vt.edu/questionaire_dev.html

Clinical Trials Reporting and Publication. CRS Report for Congress. . Eric D. Williams. This website is cited in Category: PublicationBias. Excerpt: The central issue before Congress with respect to clinical trials reporting and publication is how to balance the potential beneficial public health effects of requiring that clinical trials data be made public with the burdens that such requirements may place on companies and their innovation. Clinical trials, which are conducted regularly to test the effects of new pharmaceuticals and medical devices, cost a significant amount of money, and by their nature may present some risk to the people who participate in them. Manufacturers as well as medical journal editors have been reluctant to publish clinical trial data indicating that products in development are harmful or ineffective. The availability of such information might save a duplication of effort and studies that harm or fail to help patients. This website was last verified on 2008-02-16.

Distinguishing Association from Causation: A Backgrounder for Journalists (Kathleen Meister). This website is cited in Category: Critical appraisal. Description: This 24 page report, published on October 29, 2007, by the American Council on Science and Health, argues that randomized trials, if they can be conducted, provide strong evidence for a causal effect. In contrast, animal and in vitro experiments do not provide strong evidence for a causal relationship but rather are useful for establishing biological mechanisms. Observational studies can sometimes establish a causal relationship. The key things to look for are temporality of the relationship, strength of the relationship, a dose-response relationship, consistency across varied conditions, and biological plausibility.

Engagement of Institutions in Research (J. Thomas Puglisi). This website is cited in Category: Ethics in research. Description: In a memo dated January 26, 1999, the Director of the Division of Human Subject Protections explained that an institution becomes engaged in human subjects research (and needs a formal review of that research) when they "intervene or interact with living individuals for research purposes" or they "obtain individually identifiable private information for research purposes." What about a statistician who analyzes data collected at another site? Does this constitute a level of work that would require review at the statistician's site? You're off the hook if you "at no time obtain, receive, or possess identifiable private information." If you receive coded data that can be linked back to private information, you do need to seek approval, unless "a written agreement unequivocally prohibits release of identifying codes."

Information Is Not Entropy, Information Is Not Uncertainty!. Thomas D. Schneider, National Cancer Institute. This website is cited in Category: Information theory. Excerpt: There are many many statements in the literature which say that information is the same as entropy. The reason for this was told by Tribus. The story goes that Shannon didn't know what to call his measure so he asked von Neumann, who said `You should call it entropy ... [since] ... no one knows what entropy really is, so in a debate you will always have the advantage' (Tribus1971). This website was last verified on 2008-01-14.

Instrumental variable. Wikipedia. This website is cited in Category: UnusualData. Excerpt: In statistics and econometrics, an instrumental variable (IV, or instrument) can be used to produce a consistent estimator of a parameter when the explanatory variables (covariates) are correlated with the error terms. Such correlation can be caused by endogeneity, by omitted covariates, or by measurement errors in the covariates. In this situation, ordinary linear regression produces biased and inconsistent estimates. However, if an instrument is available, consistent estimates may still be obtained. An instrument is a variable that does not itself belong in the explanatory equation, that is correlated with the suspect explanatory variable, and that is uncorrelated with the error term.

Instrumental Variable Estimation. David A. Kenny. This website is cited in Category: UnusualData. Excerpt: One way of identifying models that cannot be estimated by using multiple regression is through the use of instrumental variables. For path analysis, the disturbance must not be correlated with each causal variable. There are three reasons why such a correlation might exist: * Spuriousness (Third Variable Causation): A variable causes both the endogenous variable and one its causal variables and that variable is not included in the model. * Reverse Causation (Feedback Model): The endogenous variable causes, either directly or indirectly, one of its causes. * Measurement Error: There is measurement error in a causal variable.

Scientific Papers and Presentations (PDF). Martha Davis. This website is cited in Category: WritingResearchPapers, Category: PresentingResearchData. Excerpt: "Scientific communication is essential for helping us to use and take care of this earth. Researchers who discover the wonders of science must tell someone about their findings in clear, complete, and concise terms. To add to the pool of scientific knowledge, scientists must synthesize available information with what they discover. If a scientist garbles words or leaves out important points, messages become unclear, and the progress of science suffers." This website was last verified on 2008-03-09.

White Paper on the Shortcomings of How Clinical Trials are Designed, Carried Out and Funded in the U.S. [PDF]. EDICT (Eliminating Disparities in Clinical Trials). This website is cited in Category: ExclusionsInResearch. Excerpt: Clinical trials are a critical resource for the discovery of new, life-saving drugs and for developing better prevention and diagnostic screening methods. Today�s most effective prevention and treatment modalities are based on previous clinical trial results. But while the need for clinical research is undisputed, how clinical trials are now conducted remains problematic. Increasing research finds major deficiencies in the way clinical trials are designed, carried out and funded in the U.S. with serious implications for the outcomes of medical research studies. Of key significance for the future of scientific innovation is the exclusion or underrepresentation of women, older people, minorities, disabled persons, and rural populations in the vast majority of the research studies conducted in the U.S. Without adequate representation of all patient populations, researchers cannot learn about potential differences among groups and cannot ensure the generalization of results.

Yes, Polling Works. Frank Newport. This website is cited in Category: Survey design. Excerpt: There's little question that some Americans are skeptical of polls and the process by which we use small samples to represent the views of millions of people. We pick up that skepticism when we poll people about polls (something we do from time to time!), and I certainly hear it when I am on a radio talk show or make a speech and get bombarded with questions about the believability of our polls, which are based on what seems to the questioners to be ridiculously small numbers of people.

The Zoo of Loglinear Analysis. Ping Li, Department of Psychology, University of Richmond. This website is cited in Category: UnusualData. Excerpt: "Loglinear Analysis is a multivariate extension of Chi Square. You use Loglinear when you have more than two qualitative variables. Chi Square is insufficient when you have more than two qualitative variables because it only tests the independence of the variables. When you have more than two, it cannot detect the varying associations and interactions between the variables. Loglinear is a goodness-of-fit test that allows you to test all the effects (the main effects, the association effects and the interaction effects) at the same time."

3M APR-DRG Severity-of-Illness Software. 3M Innovation, 3M. This website is cited in Category: MeasuringBenefitRisk. Excerpt: Grouping, validating, and pricing claims data will never be the same. The State of Maryland is leading the move toward a more equitable and accurate way to pay for health care: A severity-based payment system. Supported by years of research, Maryland is acting on the fact that patients with a higher level of severity require more healthcare resources and that there are significant variances in patient severity in the existing payment system. As the State of Maryland moves toward its implementation of having hospitals set payment rates based on the 3M� APR-DRG� Classification System�s severity scoring, hospitals might feel overwhelmed with the requirements for change. But, this change doesn�t have to be complex. In fact, it can be easy and simple, thanks to 3M APR-DRG Severity-of-Illness Software. This website was last verified on 2008-Feb. 15.

Interesting website: Occam's Razor. F. Heylighen. Accessed on 2002-10-25. One of the hallmarks of critical appraisal is the ability to search for and prefer the simplest explanation that is consistent with the data. This concept was originally voiced by a medieval philosopher, William of Occam and the principle is called Occam's razor. Here's an excerpt from this site: "One should not increase, beyond what is necessary, the number of entities required to explain anything. Occam's razor is a logical principle attributed to the mediaeval philosopher William of Occam (or Ockham).

Fallacies. Michael C. Labossiere. Accessed on 2002-11-29. "A fallacy is, very generally, an error in reasoning. This differs from a factual error, which is simply being wrong about the facts. To be more specific, a fallacy is an "argument" in which the premises given for the conclusion do not provide the needed degree of support. A deductive fallacy is a deductive argument that is invalid (it is such that it could have all true premises and still have a false conclusion). An inductive fallacy is less formal than a deductive fallacy. They are simply "arguments" which appear to be inductive arguments, but the premises do not provided enough support for the conclusion. In such cases, even if the premises were true, the conclusion would not be more likely to be true." www1.ca.nizkor.org//features/fallacies/

Statistical methods for assessing agreement between two methods of clinical measurement. J. Martin Bland and Douglas G. Altman. Accessed on 2002-11-27. "In clinical measurement comparison of a new measurement technique with an established one is often needed to see whether they agree sufficiently for the new to replace the old. Such investigations are often analysed inappropriately, notably by using correlation coefficients. The use of correlation is misleading. An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability." www.mbland.sghms.ac.uk/ba.htm
