Available in PDF, EPUB and Kindle. Book excerpt: Classification and regression trees (CART) is one of the several contemporary statistical techniques with good promise for research in many academic fields. There are very few books on CART, especially on applied CART. This book, as a good practical primer with a focus on applications, introduces the relatively new statistical technique of CART as a powerful analytical tool. The easy-to-understand (non-technical) language and illustrative graphs (tables) as well as the use of the popular statistical software program (SPSS) appeal to readers without strong statistical background. This book helps readers understand the foundation, the operation, and the interpretation of CART analysis, thus becoming knowledgeable consumers and skillful users of CART. The chapter on advanced CART procedures not yet well-discussed in the literature allows readers to effectively seek further empowerment of their research designs by extending the analytical power of CART to a whole new level. This highly practical book is specifically written for academic researchers, data analysts, and graduate students in many disciplines such as economics, social sciences, medical sciences, and sport sciences who do not have strong statistical background but still strive to take full advantage of CART as a powerful analytical tool for research in their fields.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1990. There was a time when most researchers believed that the only phenomena that counted in the social sciences were those that could be measured. To make that perfectly clear, they called any phenomenon they intended to study a 'variable', indicating that the phenomenon could vary in size, length, amount, or any other quantity. Unfortunately, not many phenomena in the human world comes naturally in quantities. If we cannot even give a useful answer to what qualitative analysis is and how it works, then it seems rather incongruent to try and involve a computer, the very essence of precision and orderliness. Isn't qualitative analysis a much too individualistic and flexible an activity to be supported by a computer? Won't a computer do exactly what qualitative researchers want to avoid, namely standardize the process? Won't it mechanize and rigidify qualitative analysis? The answer to these questions is NO, and this book explains why.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Classification of study design can help provide a common language for researchers. Within a systematic review, definition of specific study designs can help guide inclusion, assess the risk of bias, pool studies, interpret results, and grade the body of evidence. However, recent research demonstrated poor reliability for an existing classification scheme. OBJECTIVES: To review tools used to classify study designs; to select a tool for evaluation; to develop instructions for application of the tool to intervention/exposure studies; and to test the tool for accuracy and interrater reliability. METHODS: We contacted representatives from all AHRQ Evidence-based Practice Centers (EPCs), other relevant organizations, and experts in the field to identify tools used to classify study designs. Twenty-three tools were identified; 10 were relevant to our objectives. The Steering Committee ranked the 10 tools using predefined criteria. The highest-ranked tool was a design algorithm for studies of health care interventions developed, but no longer advocated, by the Cochrane Non-Randomised Studies Methods Group. This tool was used as the basis for our classification tool and was revised to encompass more study designs and to incorporate elements of other tools. A sample of 30 studies was used to test the tool. Three members of the Steering Committee developed a reference standard (i.e., the "true" classification for each study); 6 testers applied the revised tool to the studies. Interrater reliability was measured using Fleiss' kappa (o) and accuracy of the testers' classification was assessed against the reference standard. Based on feedback from the testers and the reference standard committee, the tool was further revised and tested by another 6 testers using 15 studies randomly selected from the original sample. RESULTS: In the first round of testing the inter-rater reliability was fair among the testers (o = 0.26) and the reference standard committee (o = 0.33). Disagreements occurred at all decision points in the algorithm; revisions were made based on the feedback. The second round of testing showed improved interrater reliability (o = 0.45, moderate agreement) with improved, but still low, accuracy. The most common disagreements were whether the study was "experimental" (5/15 studies) and whether there was a comparison (4/15 studies). In both rounds of testing, the level of agreement for testers who had completed graduate-level training was higher than for testers who had not completed training. CONCLUSION: Potential reasons for the observed low reliability and accuracy include the lack of clarity and comprehensiveness of the tool, inadequate reporting of the studies, and variability in user characteristics. Application of a tool to classify study designs in the context of a systematic review should be accompanied by adequate training, pilot testing, and documented decision rules.

Available in PDF, EPUB and Kindle. Book excerpt: In 2006 the National Institutes of Health (NIH) established the Clinical and Translational Science Awards (CTSA) Program, recognizing the need for a new impetus to encourage clinical and translational research. At the time it was very difficult to translate basic and clinical research into clinical and community practice; making it difficult for individual patients and communities to receive its benefits. Since its creation the CTSA Program has expanded, with 61 sites spread across the nation's academic health centers and other institutions, hoping to provide catalysts and test beds for policies and practices that can benefit clinical and translation research organizations throughout the country. The NIH contracted with the Institute of Medicine (IOM) in 2012 to conduct a study to assess and provide recommendations on appropriateness of the CTSA Program's mission and strategic goals and whether changes were needed. The study was also address the implementation of the program by the National Center for Advancing Translational Sciences (NCATS) while exploring the CTSA's contributions in the acceleration of the development of new therapeutics. A 13-member committee was established to head this task; the committee had collective expertise in community outreach and engagement, public health and health policy, bioethics, education and training, pharmaceutical research and development, program evaluation, clinical and biomedical research, and child health research. The CTSA Program at NIH: Opportunities for Advancing Clinical and Translational Research is the result of investigations into previous program evaluations and assessments, open-session meetings and conference class, and the review of scientific literature. Overall, the committee believes that the CTSA Program is significant to the advancement of clinical and translational research through its contributions. The Program would benefit from a variety of revisions, however, to make it more efficient and effective.

This book was released on 2013-04-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The internal validity of a study reflects the extent to which the design and conduct of the study have prevented bias(es). One of the key steps in a systematic review is assessment of a study's internal validity, or potential for bias. This assessment serves to: (1) identify the strengths and limitations of the included studies; (2) investigate, and potentially explain heterogeneity in findings across different studies included in a systematic review; and (3) grade the strength of evidence for a given question. The risk of bias assessment directly informs one of four key domains considered when assessing the strength of evidence. With the increase in the number of published systematic reviews and development of systematic review methodology over the past 15 years, close attention has been paid to the methods for assessing internal validity. Until recently this has been referred to as “quality assessment” or “assessment of methodological quality.” In this context “quality” refers to “the confidence that the trial design, conduct, and analysis has minimized or avoided biases in its treatment comparisons.” To facilitate the assessment of methodological quality, a plethora of tools has emerged. Some of these tools were developed for specific study designs (e.g., randomized controlled trials (RCTs), cohort studies, case-control studies), while others were intended to be applied to a range of designs. The tools often incorporate characteristics that may be associated with bias; however, many tools also contain elements related to reporting (e.g., was the study population described) and design (e.g., was a sample size calculation performed) that are not related to bias. The Cochrane Collaboration recently developed a tool to assess the potential risk of bias in RCTs. The Risk of Bias (ROB) tool was developed to address some of the shortcomings of existing quality assessment instruments, including over-reliance on reporting rather than methods. Several systematic reviews have catalogued and critiqued the numerous tools available to assess methodological quality, or risk of bias of primary studies. In summary, few existing tools have undergone extensive inter-rater reliability or validity testing. Moreover, the focus of much of the tool development or testing that has been done has been on criterion or face validity. Therefore it is unknown whether, or to what extent, the summary assessments based on these tools differentiate between studies with biased and unbiased results (i.e., studies that may over- or underestimate treatment effects). There is a clear need for inter-rater reliability testing of different tools in order to enhance consistency in their application and interpretation across different systematic reviews. Further, validity testing is essential to ensure that the tools being used can identify studies with biased results. Finally, there is a need to determine inter-rater reliability and validity in order to support the uptake and use of individual tools that are recommended by the systematic review community, and specifically the ROB tool within the Evidence-based Practice Center (EPC) Program. In this project we focused on two tools that are commonly used in systematic reviews. The Cochrane ROB tool was designed for RCTs and is the instrument recommended by The Cochrane Collaboration for use in systematic reviews of RCTs. The Newcastle-Ottawa Scale is commonly used for nonrandomized studies, specifically cohort and case-control studies.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book covers the main issues, challenges and techniques concerning the application of qualitative methodologies to the study of migration. It discusses theoretical, epistemological and empirical questions that must be considered before, during, and after undertaking qualitative research in migration studies. It also covers recent innovative developments and addresses the key issues and major challenges that qualitative migration research may face at different stages i.e. crafting the research questions, defining approaches, developing concepts and theoretical frameworks, mapping categories, selecting cases, dealing with concerns of self-reflection, collecting and processing empirical evidence through various techniques, including visual data, dealing with ethical issues, and developing policy-research dialogues. Each chapter discusses relative strengths and limitations of qualitative research. The chapters also identify the main drivers for qualitative research development in migration studies. It is a unique volume as it brings together a multidisciplinary perspective as well as illustrations of different issues derived from the research experience of the recognized authors. One additional value of this book is its geographic focus on Europe. It seeks to explore theoretical and methodological issues that are raised by distinctive features of the European context. This volume will be a useful reference source for scholars and professionals in migration studies and in social sciences as well. The publication is also addressed to graduate and post-graduate students and, more generally, to those who embark on the task of doing qualitative research for the first time in the field of migration.
