Applied psychological research is worthless unless it is used in practice, but getting research information out to the practicing community is a real challenge. This book offers the beginnings of real change to the system of professional psychology. It is the first to examine standards of practice as a method of linking practical psychological work to contemporary scientific knowledge. The result of a national conference sponsored by the American Association of Applied and Preventive Psychology, these essays challenge the discipline to ensure that scientific knowledge is actually used by practitioners. Practice standards are being developed by the government, professional and scientific associations, and by the healthcare industry.
