Methodological problems have hampered researchers' efforts to understand and control AIDS since the beginning of the epidemic. This practical book addresses these problems by using actual health research case studies to develop strategies regarding design and sampling, measurement, and analysis and modeling issues. Researchers working on both biological and behavioral aspects of the disease will find this work a singularly effective tool to improve their study designs.

On any given day, nearly half a million children are served by foster care services in the U.S. at an annual cost of over $25 billion. Growing demand and shrinking funds have so greatly stressed the child welfare system that calls for orphanages have re-entered the public debate for the first time in nearly half a century. New ideas are desperately needed to transform a system in crisis, guarantee better outcomes for children in foster care, and reduce the need for out-of-home care in the first place. Yet little is known about what works in foster care. Very few studies have examined how alumni have fared as adults or tracked long-term health effects, and even fewer have directly compared different foster care services. In one of the most comprehensive studies of adults formerly in foster care ever conducted, the Northwest Foster Care Alumni Study found that quality foster care services for children pay big dividends when they grow into adults. Key investments in highly trained staff, low caseloads, and robust supplementary services can dramatically reduce the rates of mental disorders and substance abuse later in life and increase the likelihood of completing education beyond high school and remaining employed. The results of this unparalleled study document not only the more favorable outcomes for youth who receive better services but the overall return when an investment is made in high quality foster care: every dollar invested in a child generates $1.50 in benefits to society. These findings form the core of this book's blueprint for reform. By keeping more children with their families and investing additional funds in enhanced foster care services, child welfare agencies have the opportunity to greatly improve the health, well being, and economic prospects for foster care alumni. What Works in Foster Care? presents a model foster care program that promises to revolutionize the way policymakers, administrators, case workers, and researchers think about protecting our most vulnerable youth.

Mental disorders have profound social, cultural, and economic effects throughout the world. Although most psychiatry and psychology texts provide some basic data on the prevalence and treatment of mental disorders, no previous book has ever presented such data with the breadth or depth of the current volume.
Reported here are the first results of the WHO World Mental Health (WMH) Survey Initiative, the largest coordinated series of cross-national psychiatric epidemiological surveys ever undertaken. The general population surveys in the WMH series span 17 countries in all parts of the world. In many of these countries the WMH surveys provide the first community epidemiological data ever available on mental disorders in the population. The detailed information on lifetime prevalence, age of onset, course, correlates, and treatment of mental disorders in this volume provides mental health professionals and healthcare policy planners with an unprecedented state-of-the-art reference on the cross-national descriptive epidemiology of mental disorders.

This book is a resource for health and social scientists who assess the role of stress in their studies of physical and psychiatric illness. This work discusses how stress is conceptualized, the pathways through which stressors influence the onset and progression of psychiatric and physical illness, the alternate methods of measuring stress, and how one decides on appropriate measurement.
