Book Description
Randomized clinical trials are the primary tool for evaluating new medical interventions. Randomization provides for a fair comparison between treatment and control groups, balancing out, on average, distributions of known and unknown factors among the participants. Unfortunately, these studies often lack a substantial percentage of data. This missing data reduces the benefit provided by the randomization and introduces potential biases in the comparison of the treatment groups. Missing data can arise for a variety of reasons, including the inability or unwillingness of participants to meet appointments for evaluation. And in some studies, some or all of data collection ceases when participants discontinue study treatment. Existing guidelines for the design and conduct of clinical trials, and the analysis of the resulting data, provide only limited advice on how to handle missing data. Thus, approaches to the analysis of data with an appreciable amount of missing values tend to be ad hoc and variable. The Prevention and Treatment of Missing Data in Clinical Trials concludes that a more principled approach to design and analysis in the presence of missing data is both needed and possible. Such an approach needs to focus on two critical elements: (1) careful design and conduct to limit the amount and impact of missing data and (2) analysis that makes full use of information on all randomized participants and is based on careful attention to the assumptions about the nature of the missing data underlying estimates of treatment effects. In addition to the highest priority recommendations, the book offers more detailed recommendations on the conduct of clinical trials and techniques for analysis of trial data.

Book Description
Whoever coined the adage "an ounce of prevention is worth a pound of cure" could not have known how important this adage would become. The challenge of altering the health trajectories of poor lifestyle decisions for such behaviors as smoking, drinking and using illicit drugs, violence, dropping out of school, engagement in risky sexual behaviors and crime through prevention research has led to a new discipline, prevention science. Defining Prevention Science covers this emerging field of science: its goals, its conceptual and theoretical foundations, its methods and especially its utility. Not content to simply differentiate the field from its close allies: epidemiology, psychology, neuroscience, sociology, economics, the text explains how these many disciplines enhance each other at both research and intervention levels and how prevention science draws on these biological, behavioral and social sciences to create an innovative knowledge base that has provided cost-effective, evidence-based prevention interventions and policies. To this end, familiar developmental benchmarks are recast in prevention/health promotion context, from the crucial importance of adolescence in encountering and deterring high-risk behaviors to the risks and resiliencies of single-mother families. An international group of contributors offers current findings, up-to-date methods for effective evidence-based interventions and improvements in research technologies in these key areas: Physical, cognitive and emotional vulnerability across the life course. The roles of developmental influences in prevention. Intervention development, delivery and implementation. Bringing the intervention approach to research design. New directions in analytic methods. Cost analysis and policy implications. Advances in Prevention Science: Defining Prevention Science aims to inspire further refinements in the field and encourage communication among researchers in its own and related disciplines, including public health, epidemiology, psychology, and criminology. This is the first volume in the series, Advances in Prevention Science, that provides the framework for other volume that will focus on such issues as: Prevention Science in School Settings: Complex Relationships and Processes; Preventing Crime and Violence and The Prevention of Substance Use.

Book Description
This provocative and useful volume is a step-by-step guide to assist professionals in implementing valid and useful community research and creating preventive interventions that have positive and lasting effects on the development of the community. The authors--including James G. Kelly, one of the fathers of prevention--offer valuable suggestions for developing community processes to assist the prevention researcher and the community in designing research that is embedded in the community. Experts focus on the topics that can help establish and sustain effective long-term working relationships with community members. Numerous examples illustrate how the collaborative working relationship can create the variety of resources that are needed to eventually implement policy changes stimulated by the research and help to sustain the impact of the research findings after the research has been completed. This exciting book illustrates how community research related to the prevention of mental illness and the promotion of mental health can be scientific and objective, as well as a positive collaboration between the research staff and community members. Focus upon community needs Emphasize educational activities to support the prevention research Identify points of policy impact before the research begins Enhance the development of social networks and social support systems for the development of competencies Provide criteria for the selection of systemic variables for the research Include reference to the multiple levels of a community which may affect the research topic Specify ways in which participants can identify and own the research topic Outline criteria for assessing the side effects of the prevention research In order to better understand the needs, values, commitments, and resources of the community in which he or she is working, the researcher is encouraged to select research topics derived from underlying community needs, educated the public about prevention, identify points of policy impact, and determine the informal social networks that enhance the development of social competencies in the community. The benefits of the collaborative relationship between prevention researchers and the community are strongly emphasized. A Guide to Conducting Prevention Research in the Community aims to guide citizens and professionals in implementing valid and useful community research and create preventive interventions that have positive and lasting effects on the development of the community.

Book Description
The understanding of how to reduce risk factors for mental disorders has expanded remarkably as a result of recent scientific advances. This study, mandated by Congress, reviews those advances in the context of current research and provides a targeted definition of prevention and a conceptual framework that emphasizes risk reduction. Highlighting opportunities for and barriers to interventions, the book draws on successful models for the prevention of cardiovascular disease, injuries, and smoking. In addition, it reviews the risk factors associated with Alzheimer's disease, schizophrenia, alcohol abuse and dependence, depressive disorders, and conduct disorders and evaluates current illustrative prevention programs. The models and examination provide a framework for the design, application, and evaluation of interventions intended to prevent mental disorders and the transfer of knowledge about prevention from research to clinical practice. The book presents a focused research agenda, with recommendations on how to develop effective intervention programs, create a cadre of prevention researchers, and improve coordination among federal agencies.

Book Description
Injuries are the leading cause of death and disability among people under age 35 in the United States. Despite great strides in injury prevention over the decades, injuries result in 150,000 deaths, 2.6 million hospitalizations, and 36 million visits to the emergency room each year. Reducing the Burden of Injury describes the cost and magnitude of the injury problem in America and looks critically at the current response by the public and private sectors, including: Data and surveillance needs. Research priorities. Trauma care systems development. Infrastructure support, including training for injury professionals. Firearm safety. Coordination among federal agencies. The authors define the field of injury and establish boundaries for the field regarding intentional injuries. This book highlights the crosscutting nature of the injury field, identifies opportunities to leverage resources and expertise of the numerous parties involved, and discusses issues regarding leadership at the federal level.

Book Description
This book offers a step-by-step guide to intervention research, including the methods and techniques that researchers, higher degree research students and others can use when pursuing intervention research in schools and other settings. Guided by the Intervention Research Framework, it also provides practical information on linking a program developed using a comprehensive, evidence-based approach, to research and evaluation processes. The handbook also illustrates how to select an appropriate research sample for research; how to develop valid and reliable instruments for measuring change, including how to devise appropriate measures for assessing behavioural change; how to recruit and negotiate with schools (and other settings) for research involving young people; how to measure and incorporate measures of fidelity of implementation to understand dose response and behavior change; and how to optimize data collection and dissemination. The development and longitudinal assessment of the multi award-winning School Health and Alcohol Harm Reduction Project (SHAHRP) – the first alcohol harm reduction study to assess the impact of a school-based classroom intervention on alcohol use, alcohol-related behaviors and alcohol-related harm using a harm reduction paradigm – provides a practical example of the intervention research processes described in this handbook.

Book Description
Health promotion and disease prevention are central priorities in the Centers for Disease Control and Prevention (CDC) vision. To advance research in these areas, Congress authorized and CDC established a program of university-based Centers for Research and Demonstration of Health Promotion and Disease Prevention to explore improved ways of appraising health hazards and to serve as demonstration sites for new and innovative research in public health. Begun in 1986 with three centers, there are now fourteen. In response to a CDC request to evaluate the program, Linking Research and Public Health Practice examines the vision for the prevention research centers program, the projects conducted by the centers, and the management and oversight of the program. In conducting the evaluation, the IOM committee took a broad view of how prevention research can influence the health of communities, and considered both the proximal risk factors for disease prevention and the more distal conditions for health promotion and improved equity in the distribution of risk factors.

Book Description
"The authors conducted a prevention program called Fast Track, consisting of multicomponent, home-school prevention activities carried out with at-risk children from first to 10th grades over a 10-year period, to prevent serious antisocial behavior and youth violence and achieve positive social, emotional, and academic outcomes. They describe the research that informed the design of the program as part of their Conduct Problems Prevention Research Group, how the study was implemented, and outcomes up to 20 years later. They discuss the context for youth violence prevention in the US; the developmental and intervention research that informed the design of the program; the study design and the children and families who participated in it; interventions and impacts in elementary, middle, and high school years; early adult outcomes of the program; implications for developmental theory and research on the prevention of violence; and how communities can address the problem of future violence by focusing on high-risk young children."--Provided by publisher.
