This book aims to make familiar current methods and standards for research synthesis. It describes systematic reviews and meta-
analyses, with numerous examples relevant to social work practice and policy. Systematic reviews and meta-analysis can overcome important limitations that are inherent in traditional, narrative summaries of research. The process of conducting a systematic review is described.

Evidence-based practice (EBP) promises to have a profound impact on social work practice, education, and scholarship, but adopting EBP depends on the availability of evidence to support this endeavour and on strategies to synthesize this information. Systematic reviews provide a comprehensive, unbiased method for retrieving and synthesizing
relevant research. Finding and Evaluating Evidence: Systematic Reviews and Evidence-based Practice is a concise introduction to systematic reviews that describes the steps required to complete a review and the criteria that can be used to assess the quality of existing reviews.
This pocket guide provides straight-forward information on how to
1) define a search question that clearly defines the parameters of
the problem, 2) develop a search strategy that is transparent and
comprehensive to insure that all relevant research is included in the
review, 3) assess the quality and credibility of existing research, and 4) summarize the available research to support EBP in social work. One of the distinguishing features of this book is that both quantitative and qualitative synthesis methods are presented, and examples are provided to illustrate the steps and decisions associated with each approach to research synthesis. This pocket guide is an excellent introduction to EBP and systematic reviews that will be valued by social work students, practitioners, and scholars.
Introduction
Julia H. Littell, Jacqueline Corcoran, and Vijayan Pillai in Systematic Reviews and Meta-Analysis
Published in print: 2008 Published Online:
January 2009
ISBN: 9780195326543 eISBN: 9780199864959 Item type: chapter
Publisher: Oxford University Press DOI: 10.1093/
acprof:oso/9780195326543.003.0001
This chapter defines and compares systematic reviews and meta- analyses. Systematic reviews carefully locate relevant evidence and appraise study qualities, while meta-analyses provide quantitative
summaries of evidence, showing central trends, variations, and possible explanations for differences in results across studies. The advantages and disadvantages of these review methodologies are discussed, along with appropriate applications and quality standards.
Systematic Synthesis of Qualitative Research

Qualitative synthesis within the family of systematic reviews meets an urgent need to use knowledge derived from qualitative studies to inform practice, research, and policy. Despite the contingent nature of evidence gleaned from the synthesis of qualitative studies, systematic synthesis is an important technique and, used judiciously, can deepen our
understanding of the contextual dimensions that emerge from qualitative research. This book presents an overview for planning, developing,
and implementing qualitative synthesis within existing protocols and guidelines for conducting systematic reviews. The book also explores methodological challenges, including: the philosophical tensions of
integrating qualitative synthesis within the family of systematic reviews;
the balance of comprehensive and iterative information retrieval
strategies to locate and screen qualitative research; the use of appraisal tools to assess quality of qualitative studies; the various approaches to synthesize qualitative studies, including interpretive, integrated, and aggregative; and the tensions between the generalizability and transferability of findings that emerge from qualitative synthesis.
Understanding and Applying Analytic Tools
Ross C. Brownson, Elizabeth A. Baker, Terry L. Leet, Kathleen N. Gillespie, and William R. True
in Evidence-Based Public Health
Published in print: 2010 Published Online:

This chapter describes several useful tools for evidence-based public health practice. The chapter has five main parts. First, it describes some context and processes for developing systematic reviews and economic evaluations. It then discusses several analytic tools for measuring
intervention impact and effectiveness (e.g., systematic reviews, meta- analysis). The third part describes economic evaluation, a set of methods for comparing benefits and costs. One particular type of economic
evaluation, cost-utility analysis, is described in greater detail. The fourth section discusses several challenges and opportunities in using these analytic tools. The chapter concludes with a short discussion of processes for translating evidence into public health action (e.g., expert panels, practice guidelines).
Systematic reviews

Publisher: Oxford University Press DOI: 10.1093/
acprof:oso/9780198530251.003.0008
This chapter introduces systematic reviews and provides a summary of
systematic review methods. It highlights the reasons why a researcher
should use a systematic review, as well as the instances when systematic
reviews are not an ideal research method. It also discusses the different
systematic review methods that can be used, such as data extraction
and data synthesis.
Using systematic reviews in health promotion

A systematic review aims to search for and organize information in a systematic way, using transparent searches and inclusion and exclusion criteria to try, as far as is possible, to provide an unbiased summary of the evidence. This chapter briefly describes how to undertake a
systematic review, including the important step of defining the research question, and discusses some of the problems and challenges. Using examples, it describes some of the ways in which a systematic reviews can be used in evaluating health promotion, and how to evaluate the quality and relevance of such reviews.
Formulating a Topic and Developing a Protocol
Julia H. Littell, Jacqueline Corcoran, and Vijayan Pillai in Systematic Reviews and Meta-Analysis
Published in print: 2008 Published Online:
January 2009
ISBN: 9780195326543 eISBN: 9780199864959 Item type: chapter
Publisher: Oxford University Press DOI: 10.1093/
acprof:oso/9780195326543.003.0002
This chapter considers issues in formulating a research question and developing a protocol for a systematic review. The protocol is a written plan, which specifies the objectives of the review, study eligibility criteria (the populations, interventions, comparisons, outcomes, and research designs that will be included), and methodological issues, including search strategies and plans for data extraction, data analysis, and synthesis. The chapter discusses the composition of review teams, involvement of stakeholders, and uses of logic models in planning a systematic review.
Meta-analyses and Systematic Reviews

Item type: chapter
A meta-analysis is an analysis using either aggregate results or
individual patient data from published trials. It is done to provide a more comprehensive and informative view of results than is possible with any single trial. A related activity is systematic review. Such reviews, as applied to trials, typically involve efforts to identify all trials relevant to the question of interest, whether published or not, critical appraisals of the trials, and ultimately, a conclusion as to the weight of evidence for or against the treatment. Such reviews may or may not involve formal meta-analyses. Most meta-analyses, in contrast with systematic reviews, are based exclusively on published trials.
