The contributors to this volume demonstrate that it is now possible to undertake community prevention trials of alcohol-involved problems with the same precision, good design, and careful planning that has characterized similar prevention trials for heart disease and cancer prevention. This is the first book to establish a scientific basis for the integration of research into program design and in program evaluation, making it possible to determine if community programs are effective or worth the money spent for them. In part I, the contributors address issues of outcome measures, selection of relevant community interventions, utilization of appropriate research designs and analyses, and adjustment to social and political realities. Part II reviews definitions, perspectives, and issues that provide a conceptual base for the rest of the book. Also considered are the selection and measurement of alcohol problems that may be candidate outcome variables for a community intervention study. Part III summarizes the perspectives and prior experiences of community-based approaches in other health areas (including heart disease, cancer, and adolescent health) that may be applicable to the prevention of alcohol-related problems. Experiences and implications of alcohol-prevention projects in Ontario, Texas, and Rhode Island are discussed in part IV. Part V evaluates different experimental designs, methodologies, and relative risk regression models of community-based intervention programs in alcohol prevention. The two chapters in part VI discuss the dynamic social and political realities facing community prevention trials for alcohol problems and guidelines for undertaking such trials. This bookwill be useful for state and local prevention program planners and evaluators, researchers in alcohol and substance abuse, teachers of applied research methods or social program development and planning, and government policy makers.
